## Benchmark
|
||
|
||
- [Which is the fastest web framework?](https://github.com/the-benchmarker/web-frameworks)
|
||
|
||
- [TechEmpower Framework Benchmarks](https://www.techempower.com/benchmarks/)
|
||
|
||
## 要求
|
||
|
||
| 依赖 | 说明 |
|
||
| -------- | -------- |
|
||
| [PHP](https://www.php.net/) | `>=8.2` `启用扩展intl` |
|
||
| [Swoole](https://www.swoole.com/) | `>=5.0` |
|
||
| [Laravel](https://laravel.com/)/[Lumen](https://lumen.laravel.com/) | `>=10` |
|
||
|
||
## 安装
|
||
|
||
1.通过[Composer](https://getcomposer.org/)安装([packagist](https://packagist.org/packages/hhxsv5/laravel-s))。有可能找不到`3.0`版本,解决方案移步[#81](https://github.com/hhxsv5/laravel-s/issues/81)。
|
||
```bash
|
||
# PHP >=8.2
|
||
composer require "hhxsv5/laravel-s:~3.8.0"
|
||
|
||
# PHP >=5.5.9,<=7.4.33
|
||
# composer require "hhxsv5/laravel-s:~3.7.0"
|
||
|
||
# 确保你的composer.lock文件是在版本控制中
|
||
```
|
||
|
||
2.注册Service Provider(以下两步二选一)。
|
||
|
||
- `Laravel`: 修改文件`config/app.php`,`Laravel 5.5+支持包自动发现,你应该跳过这步`
|
||
```php
|
||
'providers' => [
|
||
//...
|
||
Hhxsv5\LaravelS\Illuminate\LaravelSServiceProvider::class,
|
||
],
|
||
```
|
||
|
||
- `Lumen`: 修改文件`bootstrap/app.php`
|
||
```php
|
||
$app->register(Hhxsv5\LaravelS\Illuminate\LaravelSServiceProvider::class);
|
||
```
|
||
|
||
3.发布配置和二进制文件。
|
||
> *每次升级LaravelS后,需重新publish;点击[Release](https://github.com/hhxsv5/laravel-s/releases)去了解各个版本的变更记录。*
|
||
|
||
```bash
|
||
php artisan laravels publish
|
||
# 配置文件:config/laravels.php
|
||
# 二进制文件:bin/laravels bin/fswatch bin/inotify
|
||
```
|
||
|
||
4.修改配置`config/laravels.php`:监听的IP、端口等,请参考[配置项](https://github.com/hhxsv5/laravel-s/blob/PHP-8.x/Settings-CN.md)。
|
||
|
||
5.性能调优
|
||
|
||
- [调整内核参数](https://wiki.swoole.com/#/other/sysctl?id=%e5%86%85%e6%a0%b8%e5%8f%82%e6%95%b0%e8%b0%83%e6%95%b4)
|
||
|
||
- [Worker数量](https://wiki.swoole.com/#/server/setting?id=worker_num):LaravelS 使用 Swoole 的`同步IO`模式,`worker_num`设置的越大并发性能越好,但会造成更多的内存占用和进程切换开销。如果`1`个请求耗时`100ms`,为了提供`1000QPS`的并发能力,至少需要配置`100`个Worker进程,计算方法:worker_num = 1000QPS/(1s/1ms) = 100,故需进行增量压测计算出最佳的`worker_num`。
|
||
|
||
- [Task Worker数量](https://wiki.swoole.com/#/server/setting?id=task_worker_num)
|
||
|
||
|
||
## 运行
|
||
> `在运行之前,请先仔细阅读:`[注意事项](https://github.com/hhxsv5/laravel-s/blob/PHP-8.x/README-CN.md#%E6%B3%A8%E6%84%8F%E4%BA%8B%E9%A1%B9)(这非常重要)。
|
||
|
||
- 操作命令:`php bin/laravels {start|stop|restart|reload|info|help}`。
|
||
|
||
| 命令 | 说明 |
|
||
| --------- | --------- |
|
||
| start | 启动LaravelS,展示已启动的进程列表 "*ps -ef|grep laravels*" |
|
||
| stop | 停止LaravelS,并触发自定义进程的`onStop`方法 |
|
||
| restart | 重启LaravelS:先平滑`Stop`,然后再`Start`;在`Start`完成之前,服务是`不可用的` |
|
||
| reload | 平滑重启所有Task/Worker/Timer进程(这些进程内包含了你的业务代码),并触发自定义进程的`onReload`方法,不会重启Master/Manger进程;修改`config/laravels.php`后,你`只有`调用`restart`来完成重启 |
|
||
| info | 显示组件的版本信息 |
|
||
| help | 显示帮助信息 |
|
||
|
||
- 启动选项,针对`start`和`restart`命令。
|
||
|
||
| 选项 | 说明 |
|
||
| --------- | --------- |
|
||
| -d|--daemonize | 以守护进程的方式运行,此选项将覆盖`laravels.php`中`swoole.daemonize`设置 |
|
||
| -e|--env | 指定运行的环境,如`--env=testing`将会优先使用配置文件`.env.testing`,这个特性要求`Laravel 5.2+` |
|
||
| -i|--ignore | 忽略检查Master进程的PID文件 |
|
||
| -x|--x-version | 记录当前工程的版本号(分支),保存在`$_ENV`/`$_SERVER`中,访问方式:`$_ENV['X_VERSION']` `$_SERVER['X_VERSION']` `$request->server->get('X_VERSION')` |
|
||
|
||
- `运行时`文件:`start`时会自动执行`php artisan laravels config`并生成这些文件,开发者一般不需要关注它们,建议将它们加到`.gitignore`中。
|
||
|
||
| 文件 | 说明 |
|
||
| --------- | --------- |
|
||
| storage/laravels.conf | LaravelS的`运行时`配置文件 |
|
||
| storage/laravels.pid | Master进程的PID文件 |
|
||
| storage/laravels-timer-process.pid | 定时器Timer进程的PID文件 |
|
||
| storage/laravels-custom-processes.pid | 所有自定义进程的PID文件 |
|
||
|
||
## 部署
|
||
> 建议通过[Supervisord](http://supervisord.org/)监管主进程,前提是不能加`-d`选项并且设置`swoole.daemonize`为`false`。

|
||
## 启用WebSocket服务器
|
||
> WebSocket服务器监听的IP和端口与Http服务器相同。
|
||
|
||
1.创建WebSocket Handler类,并实现接口`WebSocketHandlerInterface`。start时会自动实例化,不需要手动创建实例。
|
||
|
||
```php
|
||
namespace App\Services;
|
||
use Hhxsv5\LaravelS\Swoole\WebSocketHandlerInterface;
|
||
use Swoole\Http\Request;
|
||
use Swoole\Http\Response;
|
||
use Swoole\WebSocket\Frame;
|
||
use Swoole\WebSocket\Server;
|
||
/**
|
||
* @see https://wiki.swoole.com/#/start/start_ws_server
|
||
*/
|
||
class WebSocketService implements WebSocketHandlerInterface
|
||
{
|
||
// 声明没有参数的构造函数
|
||
public function __construct()
|
||
{
|
||
}
|
||
// public function onHandShake(Request $request, Response $response)
|
||
// {
|
||
// 自定义握手:https://wiki.swoole.com/#/websocket_server?id=onhandshake
|
||
// 成功握手之后会自动触发onOpen事件
|
||
// }
|
||
public function onOpen(Server $server, Request $request)
|
||
{
|
||
// 在触发onOpen事件之前,建立WebSocket的HTTP请求已经经过了Laravel的路由,
|
||
// 所以Laravel的Request、Auth等信息是可读的,Session是可读写的,但仅限在onOpen事件中。
|
||
// \Log::info('New WebSocket connection', [$request->fd, request()->all(), session()->getId(), session('xxx'), session(['yyy' => time()])]);
|
||
// 此处抛出的异常会被上层捕获并记录到Swoole日志,开发者需要手动try/catch
|
||
$server->push($request->fd, 'Welcome to LaravelS');
|
||
}
|
||
public function onMessage(Server $server, Frame $frame)
|
||
{
|
||
// \Log::info('Received message', [$frame->fd, $frame->data, $frame->opcode, $frame->finish]);
|
||
// 此处抛出的异常会被上层捕获并记录到Swoole日志,开发者需要手动try/catch
|
||
$server->push($frame->fd, date('Y-m-d H:i:s'));
|
||
}
|
||
public function onClose(Server $server, $fd, $reactorId)
|
||
{
|
||
// 此处抛出的异常会被上层捕获并记录到Swoole日志,开发者需要手动try/catch
|
||
}
|
||
}
|
||
```
|
||
|
||
2.更改配置`config/laravels.php`。
|
||
|
||
```php
|
||
// ...
|
||
'websocket' => [
|
||
'enable' => true, // 注意:设置enable为true
|
||
'handler' => \App\Services\WebSocketService::class,
|
||
],
|
||
'swoole' => [
|
||
//...
|
||
// dispatch_mode只能设置为2、4、5,https://wiki.swoole.com/#/server/setting?id=dispatch_mode
|
||
'dispatch_mode' => 2,
|
||
//...
|
||
],
|
||
// ...
|
||
```
|
||
|
||
3.使用`SwooleTable`绑定FD与UserId,可选的,[Swoole Table示例](#使用swooletable)。也可以用其他全局存储服务,例如Redis/Memcached/MySQL,但需要注意多个`Swoole Server`实例时FD可能冲突。
|
||
|
||
4.与Nginx配合使用(推荐)
|
||
> 参考 [WebSocket代理](http://nginx.org/en/docs/http/websocket.html)
|
||
|
||
```nginx
|
||
map $http_upgrade $connection_upgrade {
|
||
default upgrade;
|
||
'' close;
|
||
}
|
||
upstream swoole {
|
||
# 通过 IP:Port 连接
|
||
server 127.0.0.1:5200 weight=5 max_fails=3 fail_timeout=30s;
|
||
# 通过 UnixSocket Stream 连接,小诀窍:将socket文件放在/dev/shm目录下,可获得更好的性能
|
||
#server unix:/yourpath/laravel-s-test/storage/laravels.sock weight=5 max_fails=3 fail_timeout=30s;
|
||
#server 192.168.1.1:5200 weight=3 max_fails=3 fail_timeout=30s;
|
||
#server 192.168.1.2:5200 backup;
|
||
keepalive 16;
|
||
}
|
||
server {
|
||
listen 80;
|
||
# 别忘了绑Host
|
||
server_name laravels.com;
|
||
root /yourpath/laravel-s-test/public;
|
||
access_log /yourpath/log/nginx/$server_name.access.log main;
|
||
autoindex off;
|
||
index index.html index.htm;
|
||
# Nginx处理静态资源(建议开启gzip),LaravelS处理动态资源。
|
||
location / {
|
||
try_files $uri @laravels;
|
||
}
|
||
# 当请求PHP文件时直接响应404,防止暴露public/*.php
|
||
#location ~* \.php$ {
|
||
# return 404;
|
||
#}
|
||
# Http和WebSocket共存,Nginx通过location区分
|
||
# !!! WebSocket连接时路径为/ws
|
||
# Javascript: var ws = new WebSocket("ws://laravels.com/ws");
|
||
location =/ws {
|
||
# proxy_connect_timeout 60s;
|
||
# proxy_send_timeout 60s;
|
||
# proxy_read_timeout:如果60秒内被代理的服务器没有响应数据给Nginx,那么Nginx会关闭当前连接;同时,Swoole的心跳设置也会影响连接的关闭
|
||
# proxy_read_timeout 60s;
|
||
proxy_http_version 1.1;
|
||
proxy_set_header X-Real-IP $remote_addr;
|
||
proxy_set_header X-Real-PORT $remote_port;
|
||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||
proxy_set_header Host $http_host;
|
||
proxy_set_header Scheme $scheme;
|
||
proxy_set_header Server-Protocol $server_protocol;
|
||
proxy_set_header Server-Name $server_name;
|
||
proxy_set_header Server-Addr $server_addr;
|
||
proxy_set_header Server-Port $server_port;
|
||
proxy_set_header Upgrade $http_upgrade;
|
||
proxy_set_header Connection $connection_upgrade;
|
||
proxy_pass http://swoole;
|
||
}
|
||
location @laravels {
|
||
# proxy_connect_timeout 60s;
|
||
# proxy_send_timeout 60s;
|
||
# proxy_read_timeout 60s;
|
||
proxy_http_version 1.1;
|
||
proxy_set_header Connection "";
|
||
proxy_set_header X-Real-IP $remote_addr;
|
||
proxy_set_header X-Real-PORT $remote_port;
|
||
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
|
||
proxy_set_header Host $http_host;
|
||
proxy_set_header Scheme $scheme;
|
||
proxy_set_header Server-Protocol $server_protocol;
|
||
proxy_set_header Server-Name $server_name;
|
||
proxy_set_header Server-Addr $server_addr;
|
||
proxy_set_header Server-Port $server_port;
|
||
proxy_pass http://swoole;
|
||
}
|
||
}
|
||
```
|
||
|
||
5.心跳配置
|
||
|
||
- Swoole的心跳配置
|
||
|
||
```php
|
||
// config/laravels.php
|
||
'swoole' => [
|
||
//...
|
||
// 表示每60秒遍历一次,一个连接如果600秒内未向服务器发送任何数据,此连接将被强制关闭
|
||
'heartbeat_idle_time' => 600,
|
||
'heartbeat_check_interval' => 60,
|
||
//...
|
||
],
|
||
```
|
||
|
||
- Nginx读取代理服务器超时的配置
|
||
|
||
```nginx
|
||
# 如果60秒内被代理的服务器没有响应数据给Nginx,那么Nginx会关闭当前连接
|
||
proxy_read_timeout 60s;
|
||
```
|
||
|
||
6.在控制器中推送数据
|
||
|
||
```php
|
||
namespace App\Http\Controllers;
|
||
class TestController extends Controller
|
||
{
|
||
public function push()
|
||
{
|
||
$fd = 1; // Find fd by userId from a map [userId=>fd].
|
||
/**@var \Swoole\WebSocket\Server $swoole */
|
||
$swoole = app('swoole');
|
||
$success = $swoole->push($fd, 'Push data to fd#1 in Controller');
|
||
var_dump($success);
|
||
}
|
||
}
|
||
```
|
||
|
||
## 监听事件
|
||
|
||
### 系统事件
|
||
> 通常,你可以在这些事件中重置或销毁一些全局或静态的变量,也可以修改当前的请求和响应。
|
||
|
||
- `laravels.received_request` 将`Swoole\Http\Request`转成`Illuminate\Http\Request`后,在Laravel内核处理请求前。
|
||
|
||
```php
|
||
// 修改`app/Providers/EventServiceProvider.php`, 添加下面监听代码到boot方法中
|
||
// 如果变量$events不存在,你也可以通过Facade调用\Event::listen()。
|
||
$events->listen('laravels.received_request', function (\Illuminate\Http\Request $req, $app) {
|
||
$req->query->set('get_key', 'hhxsv5');// 修改querystring
|
||
$req->request->set('post_key', 'hhxsv5'); // 修改post body
|
||
});
|
||
```
|
||
|
||
- `laravels.generated_response` 在Laravel内核处理完请求后,将`Illuminate\Http\Response`转成`Swoole\Http\Response`之前(下一步将响应给客户端)。
|
||
|
||
```php
|
||
// 修改`app/Providers/EventServiceProvider.php`, 添加下面监听代码到boot方法中
|
||
// 如果变量$events不存在,你也可以通过Facade调用\Event::listen()。
|
||
$events->listen('laravels.generated_response', function (\Illuminate\Http\Request $req, \Symfony\Component\HttpFoundation\Response $rsp, $app) {
|
||
$rsp->headers->set('header-key', 'hhxsv5');// 修改header
|
||
});
|
||
```
|
||
|
||
### 自定义的异步事件
|
||
> 此特性依赖`Swoole`的`AsyncTask`,必须先设置`config/laravels.php`的`swoole.task_worker_num`。异步事件的处理能力受Task进程数影响,需合理设置[task_worker_num](https://wiki.swoole.com/#/server/setting?id=task_worker_num)。
|
||
|
||
1.创建事件类。
|
||
|
||
```php
|
||
use Hhxsv5\LaravelS\Swoole\Task\Event;
|
||
class TestEvent extends Event
|
||
{
|
||
protected $listeners = [
|
||
// 监听器列表
|
||
TestListener1::class,
|
||
// TestListener2::class,
|
||
];
|
||
private $data;
|
||
public function __construct($data)
|
||
{
|
||
$this->data = $data;
|
||
}
|
||
public function getData()
|
||
{
|
||
return $this->data;
|
||
}
|
||
}
|
||
```
|
||
|
||
2.创建监听器类。
|
||
|
||
```php
|
||
use Hhxsv5\LaravelS\Swoole\Task\Event;
|
||
use Hhxsv5\LaravelS\Swoole\Task\Task;
|
||
use Hhxsv5\LaravelS\Swoole\Task\Listener;
|
||
class TestListener1 extends Listener
|
||
{
|
||
public function handle(Event $event)
|
||
{
|
||
\Log::info(__CLASS__ . ':handle start', [$event->getData()]);
|
||
sleep(2);// 模拟一些慢速的事件处理
|
||
// 监听器中也可以投递Task,但不支持Task的finish()回调。
|
||
// 注意:config/laravels.php中修改配置task_ipc_mode为1或2,参考 https://wiki.swoole.com/#/server/setting?id=task_ipc_mode
|
||
$ret = Task::deliver(new TestTask('task data'));
|
||
var_dump($ret);
|
||
// 此处抛出的异常会被上层捕获并记录到Swoole日志,开发者需要手动try/catch
|
||
// return false; // 停止将事件传播到后面的监听器
|
||
}
|
||
}
|
||
```
|
||
|
||
3.触发事件。
|
||
|
||
```php
|
||
// 实例化TestEvent并通过fire触发,此操作是异步的,触发后立即返回,由Task进程继续处理监听器中的handle逻辑
|
||
use Hhxsv5\LaravelS\Swoole\Task\Event;
|
||
$event = new TestEvent('event data');
|
||
// $event->delay(10); // 延迟10秒触发
|
||
// $event->setTries(3); // 出现异常时,累计尝试3次
|
||
$success = Event::fire($event);
|
||
var_dump($success);// 判断是否触发成功
|
||
```
|
||
|
||
## 异步的任务队列
|
||
> 此特性依赖`Swoole`的`AsyncTask`,必须先设置`config/laravels.php`的`swoole.task_worker_num`。异步任务的处理能力受Task进程数影响,需合理设置[task_worker_num](https://wiki.swoole.com/#/server/setting?id=task_worker_num)。
|
||
|
||
1.创建任务类。
|
||
|
||
```php
|
||
use Hhxsv5\LaravelS\Swoole\Task\Task;
|
||
class TestTask extends Task
|
||
{
|
||
private $data;
|
||
private $result;
|
||
public function __construct($data)
|
||
{
|
||
$this->data = $data;
|
||
}
|
||
// 处理任务的逻辑,运行在Task进程中,不能投递任务
|
||
public function handle()
|
||
{
|
||
\Log::info(__CLASS__ . ':handle start', [$this->data]);
|
||
sleep(2);// 模拟一些慢速的事件处理
|
||
// 此处抛出的异常会被上层捕获并记录到Swoole日志,开发者需要手动try/catch
|
||
$this->result = 'the result of ' . $this->data;
|
||
}
|
||
// 可选的,完成事件,任务处理完后的逻辑,运行在Worker进程中,可以投递任务
|
||
public function finish()
|
||
{
|
||
\Log::info(__CLASS__ . ':finish start', [$this->result]);
|
||
Task::deliver(new TestTask2('task2')); // 投递其他任务
|
||
}
|
||
}
|
||
```
|
||
|
||
2.投递任务。
|
||
|
||
```php
|
||
// 实例化TestTask并通过deliver投递,此操作是异步的,投递后立即返回,由Task进程继续处理TestTask中的handle逻辑
|
||
use Hhxsv5\LaravelS\Swoole\Task\Task;
|
||
$task = new TestTask('task data');
|
||
// $task->delay(3); // 延迟3秒投递任务
|
||
// $task->setTries(3); // 出现异常时,累计尝试3次
|
||
$ret = Task::deliver($task);
|
||
var_dump($ret);// 判断是否投递成功
|
||
```
|
||
|
||
## 毫秒级定时任务
|
||
> 基于[Swoole的毫秒定时器](https://wiki.swoole.com/#/timer),封装的定时任务,取代`Linux`的`Crontab`。
|
||
|
||
1.创建定时任务类。
|
||
```php
|
||
namespace App\Jobs\Timer;
|
||
use App\Tasks\TestTask;
|
||
use Swoole\Coroutine;
|
||
use Hhxsv5\LaravelS\Swoole\Task\Task;
|
||
use Hhxsv5\LaravelS\Swoole\Timer\CronJob;
|
||
class TestCronJob extends CronJob
|
||
{
|
||
protected $i = 0;
|
||
// !!! 定时任务的`interval`和`isImmediate`有两种配置方式(二选一):一是重载对应的方法,二是注册定时任务时传入参数。
|
||
// --- 重载对应的方法来返回配置:开始
|
||
public function interval()
|
||
{
|
||
return 1000;// 每1秒运行一次
|
||
}
|
||
public function isImmediate()
|
||
{
|
||
return false;// 是否立即执行第一次,false则等待间隔时间后执行第一次
|
||
}
|
||
// --- 重载对应的方法来返回配置:结束
|
||
public function run()
|
||
{
|
||
\Log::info(__METHOD__, ['start', $this->i, microtime(true)]);
|
||
// do something
|
||
// sleep(1); // Swoole < 2.1
|
||
Coroutine::sleep(1); // Swoole>=2.1 run()方法已自动创建了协程。
|
||
$this->i++;
|
||
\Log::info(__METHOD__, ['end', $this->i, microtime(true)]);
|
||
|
||
if ($this->i >= 10) { // 运行10次后不再执行
|
||
\Log::info(__METHOD__, ['stop', $this->i, microtime(true)]);
|
||
$this->stop(); // 终止此定时任务,但restart/reload后会再次运行
|
||
// CronJob中也可以投递Task,但不支持Task的finish()回调。
|
||
// 注意:修改config/laravels.php,配置task_ipc_mode为1或2,参考 https://wiki.swoole.com/#/server/setting?id=task_ipc_mode
|
||
$ret = Task::deliver(new TestTask('task data'));
|
||
var_dump($ret);
|
||
}
|
||
// 此处抛出的异常会被上层捕获并记录到Swoole日志,开发者需要手动try/catch
|
||
}
|
||
}
|
||
```
|
||
|
||
2.注册定时任务类。
|
||
|
||
```php
|
||
// 在"config/laravels.php"注册定时任务类
|
||
[
|
||
// ...
|
||
'timer' => [
|
||
'enable' => true, // 启用Timer
|
||
'jobs' => [ // 注册的定时任务类列表
|
||
// 启用LaravelScheduleJob来执行`php artisan schedule:run`,每分钟一次,替代Linux Crontab
|
||
// \Hhxsv5\LaravelS\Illuminate\LaravelScheduleJob::class,
|
||
// 两种配置参数的方式:
|
||
// [\App\Jobs\Timer\TestCronJob::class, [1000, true]], // 注册时传入参数
|
||
\App\Jobs\Timer\TestCronJob::class, // 重载对应的方法来返回参数
|
||
],
|
||
'max_wait_time' => 5, // Reload时最大等待时间
|
||
// 打开全局定时器开关:当多实例部署时,确保只有一个实例运行定时任务,此功能依赖 Redis,具体请看 https://laravel.com/docs/7.x/redis
|
||
'global_lock' => false,
|
||
'global_lock_key' => config('app.name', 'Laravel'),
|
||
],
|
||
// ...
|
||
];
|
||
```
|
||
|
||
3.注意在构建服务器集群时,会启动多个`定时器`,要确保只启动一个定期器,避免重复执行定时任务。
|
||
|
||
4.LaravelS `v3.4.0`开始支持热重启[Reload]`定时器`进程,LaravelS 在收到`SIGUSR1`信号后会等待`max_wait_time`(默认5)秒再结束进程,然后`Manager`进程会重新拉起`定时器`进程。
|
||
|
||
5.如果你仅需要用到`分钟级`的定时任务,建议启用`Hhxsv5\LaravelS\Illuminate\LaravelScheduleJob`来替代Linux Crontab,这样就可以沿用[Laravel任务调度](https://learnku.com/docs/laravel/7.x/scheduling/7492)的编码习惯,配置`Kernel`即可。
|
||
|
||
```php
|
||
// app/Console/Kernel.php
|
||
protected function schedule(Schedule $schedule)
|
||
{
|
||
// runInBackground()方法会新启子进程执行任务,这是异步的,不会影响其他任务的执行时机
|
||
$schedule->command(TestCommand::class)->runInBackground()->everyMinute();
|
||
}
|
||
```
|
||
|
||
## 修改代码后自动Reload
|
||
|
||
- 基于`inotify`,仅支持Linux。
|
||
|
||
1.安装[inotify](http://pecl.php.net/package/inotify)扩展。
|
||
|
||
2.开启[配置项](https://github.com/hhxsv5/laravel-s/blob/PHP-8.x/Settings-CN.md#inotify_reloadenable)。
|
||
|
||
3.注意:`inotify`只有在`Linux`内修改文件才能收到文件变更事件,建议使用最新版Docker,[Vagrant解决方案](https://github.com/mhallin/vagrant-notify-forwarder)。
|
||
|
||
- 基于`fswatch`,支持OS X、Linux、Windows。
|
||
|
||
1.安装[fswatch](https://github.com/emcrisostomo/fswatch)。
|
||
|
||
2.在项目根目录下运行命令。
|
||
|
||
```bash
|
||
# 监听当前目录
|
||
./bin/fswatch
|
||
# 监听app目录
|
||
./bin/fswatch ./app
|
||
```
|
||
|
||
- 基于`inotifywait`,仅支持Linux。
|
||
|
||
1.安装[inotify-tools](https://github.com/rvoicilas/inotify-tools)。
|
||
|
||
2.在项目根目录下运行命令。
|
||
|
||
```bash
|
||
# 监听当前目录
|
||
./bin/inotify
|
||
# 监听app目录
|
||
./bin/inotify ./app
|
||
```
|
||
|
||
- 当以上方法都不行时,终极解决方案:配置`max_request=1,worker_num=1`,这样`Worker`进程处理完一个请求就会重启,这种方法的性能非常差,`故仅限在开发环境使用`。
|
||
|
||
## 在你的项目中使用`SwooleServer`实例
|
||
|
||
```php
|
||
/**
|
||
* 如果启用WebSocket server,$swoole是`Swoole\WebSocket\Server`的实例,否则是是`Swoole\Http\Server`的实例
|
||
* @var \Swoole\WebSocket\Server|\Swoole\Http\Server $swoole
|
||
*/
|
||
$swoole = app('swoole');
|
||
var_dump($swoole->stats());
|
||
$swoole->push($fd, 'Push WebSocket message');
|
||
```
|
||
|
||
## 使用`SwooleTable`
|
||
|
||
1.定义Table,支持定义多个Table。
|
||
> Swoole启动之前会创建定义的所有Table。
|
||
|
||
```php
|
||
// 在"config/laravels.php"配置
|
||
[
|
||
// ...
|
||
'swoole_tables' => [
|
||
// 场景:WebSocket中UserId与FD绑定
|
||
'ws' => [// Key为Table名称,使用时会自动添加Table后缀,避免重名。这里定义名为wsTable的Table
|
||
'size' => 102400,//Table的最大行数
|
||
'column' => [// Table的列定义
|
||
['name' => 'value', 'type' => \Swoole\Table::TYPE_INT, 'size' => 8],
|
||
],
|
||
],
|
||
//...继续定义其他Table
|
||
],
|
||
// ...
|
||
];
|
||
```
|
||
|
||
2.访问Table:所有的Table实例均绑定在`SwooleServer`上,通过`app('swoole')->xxxTable`访问。
|
||
|
||
```php
|
||
namespace App\Services;
|
||
use Hhxsv5\LaravelS\Swoole\WebSocketHandlerInterface;
|
||
use Swoole\Http\Request;
|
||
use Swoole\WebSocket\Frame;
|
||
use Swoole\WebSocket\Server;
|
||
class WebSocketService implements WebSocketHandlerInterface
|
||
{
|
||
/**@var \Swoole\Table $wsTable */
|
||
private $wsTable;
|
||
public function __construct()
|
||
{
|
||
$this->wsTable = app('swoole')->wsTable;
|
||
}
|
||
// 场景:WebSocket中UserId与FD绑定
|
||
public function onOpen(Server $server, Request $request)
|
||
{
|
||
// var_dump(app('swoole') === $server);// 同一实例
|
||
/**
|
||
* 获取当前登录的用户
|
||
* 此特性要求建立WebSocket连接的路径要经过Authenticate之类的中间件。
|
||
* 例如:
|
||
* 浏览器端:var ws = new WebSocket("ws://127.0.0.1:5200/ws");
|
||
* 那么Laravel中/ws路由就需要加上类似Authenticate的中间件。
|
||
* Route::get('/ws', function () {
|
||
* // 响应状态码200的任意内容
|
||
* return 'websocket';
|
||
* })->middleware(['auth']);
|
||
*/
|
||
// $user = Auth::user();
|
||
// $userId = $user ? $user->id : 0; // 0 表示未登录的访客用户
|
||
$userId = mt_rand(1000, 10000);
|
||
// if (!$userId) {
|
||
// // 未登录用户直接断开连接
|
||
// $server->disconnect($request->fd);
|
||
// return;
|
||
// }
|
||
$this->wsTable->set('uid:' . $userId, ['value' => $request->fd]);// 绑定uid到fd的映射
|
||
$this->wsTable->set('fd:' . $request->fd, ['value' => $userId]);// 绑定fd到uid的映射
|
||
$server->push($request->fd, "Welcome to LaravelS #{$request->fd}");
|
||
}
|
||
public function onMessage(Server $server, Frame $frame)
|
||
{
|
||
// 广播
|
||
foreach ($this->wsTable as $key => $row) {
|
||
if (strpos($key, 'uid:') === 0 && $server->isEstablished($row['value'])) {
|
||
$content = sprintf('Broadcast: new message "%s" from #%d', $frame->data, $frame->fd);
|
||
$server->push($row['value'], $content);
|
||
}
|
||
}
|
||
}
|
||
public function onClose(Server $server, $fd, $reactorId)
|
||
{
|
||
$uid = $this->wsTable->get('fd:' . $fd);
|
||
if ($uid !== false) {
|
||
$this->wsTable->del('uid:' . $uid['value']); // 解绑uid映射
|
||
}
|
||
$this->wsTable->del('fd:' . $fd);// 解绑fd映射
|
||
$server->push($fd, "Goodbye #{$fd}");
|
||
}
|
||
}
|
||
```
|
||
|
||
## 多端口混合协议
|
||

|
||
|
||
为了使我们的主服务器能支持除`HTTP`和`WebSocket`外的更多协议,我们引入了`Swoole`的`多端口混合协议`特性,在LaravelS中称为`Socket`。现在,可以很方便地在Laravel上构建`TCP/UDP`应用。
|
||
|
||
1. 创建`Socket`处理类,继承`Hhxsv5\LaravelS\Swoole\Socket\{TcpSocket|UdpSocket|Http|WebSocket}`
|
||
|
||
```php
|
||
namespace App\Sockets;
|
||
use Hhxsv5\LaravelS\Swoole\Socket\TcpSocket;
|
||
use Swoole\Server;
|
||
class TestTcpSocket extends TcpSocket
|
||
{
|
||
public function onConnect(Server $server, $fd, $reactorId)
|
||
{
|
||
\Log::info('New TCP connection', [$fd]);
|
||
$server->send($fd, 'Welcome to LaravelS.');
|
||
}
|
||
public function onReceive(Server $server, $fd, $reactorId, $data)
|
||
{
|
||
\Log::info('Received data', [$fd, $data]);
|
||
$server->send($fd, 'LaravelS: ' . $data);
|
||
if ($data === "quit\r\n") {
|
||
$server->send($fd, 'LaravelS: bye' . PHP_EOL);
|
||
$server->close($fd);
|
||
}
|
||
}
|
||
public function onClose(Server $server, $fd, $reactorId)
|
||
{
|
||
\Log::info('Close TCP connection', [$fd]);
|
||
$server->send($fd, 'Goodbye');
|
||
}
|
||
}
|
||
```
|
||
|
||
这些连接和主服务器上的HTTP/WebSocket连接共享`Worker`进程,因此可以在这些事件回调中使用LaravelS提供的`异步任务投递`、`SwooleTable`、Laravel提供的组件如`DB`、`Eloquent`等。同时,如果需要使用该协议端口的`Swoole\Server\Port`对象,只需要像如下代码一样访问`Socket`类的成员`swoolePort`即可。
|
||
|
||
```php
|
||
public function onReceive(Server $server, $fd, $reactorId, $data)
|
||
{
|
||
$port = $this->swoolePort; // 获得`Swoole\Server\Port`对象
|
||
}
|
||
```
|
||
|
||
```php
|
||
namespace App\Http\Controllers;
|
||
class TestController extends Controller
|
||
{
|
||
public function test()
|
||
{
|
||
/**@var \Swoole\Http\Server|\Swoole\WebSocket\Server $swoole */
|
||
$swoole = app('swoole');
|
||
// $swoole->ports:遍历所有Port对象,https://wiki.swoole.com/#/server/properties?id=ports
|
||
$port = $swoole->ports[1]; // 获得`Swoole\Server\Port`对象,$port[0]是主服务器的端口
|
||
foreach ($port->connections as $fd) { // 遍历所有连接
|
||
// $swoole->send($fd, 'Send tcp message');
|
||
// if($swoole->isEstablished($fd)) {
|
||
// $swoole->push($fd, 'Send websocket message');
|
||
// }
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
2. 注册套接字。
|
||
|
||
```php
|
||
// 修改文件 config/laravels.php
|
||
// ...
|
||
'sockets' => [
|
||
[
|
||
'host' => '127.0.0.1',
|
||
'port' => 5291,
|
||
'type' => SWOOLE_SOCK_TCP,// 支持的嵌套字类型:https://wiki.swoole.com/#/consts?id=socket-%e7%b1%bb%e5%9e%8b
|
||
'settings' => [// Swoole可用的配置项:https://wiki.swoole.com/#/server/port?id=%e5%8f%af%e9%80%89%e5%8f%82%e6%95%b0
|
||
'open_eof_check' => true,
|
||
'package_eof' => "\r\n",
|
||
],
|
||
'handler' => \App\Sockets\TestTcpSocket::class,
|
||
'enable' => true, // 是否启用,默认为true
|
||
],
|
||
],
|
||
```
|
||
|
||
关于心跳配置,只能设置在`主服务器`上,不能配置在`套接字`上,但`套接字`会继承`主服务器`的心跳配置。
|
||
|
||
对于TCP协议,`dispatch_mode`选项设为`1/3`时,底层会屏蔽`onConnect`/`onClose`事件,原因是这两种模式下无法保证`onConnect`/`onClose`/`onReceive`的顺序。如果需要用到这两个事件,请将`dispatch_mode`改为`2/4/5`,[参考](https://wiki.swoole.com/#/server/setting?id=dispatch_mode)。
|
||
|
||
```php
|
||
'swoole' => [
|
||
//...
|
||
'dispatch_mode' => 2,
|
||
//...
|
||
];
|
||
```
|
||
|
||
3. 测试。
|
||
|
||
- TCP:`telnet 127.0.0.1 5291`
|
||
|
||
- UDP:Linux下 `echo "Hello LaravelS" > /dev/udp/127.0.0.1/5292`
|
||
|
||
4. 其他协议的注册示例。
|
||
|
||
- UDP
|
||
```php
|
||
'sockets' => [
|
||
[
|
||
'host' => '0.0.0.0',
|
||
'port' => 5292,
|
||
'type' => SWOOLE_SOCK_UDP,
|
||
'settings' => [
|
||
'open_eof_check' => true,
|
||
'package_eof' => "\r\n",
|
||
],
|
||
'handler' => \App\Sockets\TestUdpSocket::class,
|
||
],
|
||
],
|
||
```
|
||
|
||
- Http
|
||
```php
|
||
'sockets' => [
|
||
[
|
||
'host' => '0.0.0.0',
|
||
'port' => 5293,
|
||
'type' => SWOOLE_SOCK_TCP,
|
||
'settings' => [
|
||
'open_http_protocol' => true,
|
||
],
|
||
'handler' => \App\Sockets\TestHttp::class,
|
||
],
|
||
],
|
||
```
|
||
|
||
- WebSocket:主服务器必须`开启WebSocket`,即需要将`websocket.enable`置为`true`。
|
||
```php
|
||
'sockets' => [
|
||
[
|
||
'host' => '0.0.0.0',
|
||
'port' => 5294,
|
||
'type' => SWOOLE_SOCK_TCP,
|
||
'settings' => [
|
||
'open_http_protocol' => true,
|
||
'open_websocket_protocol' => true,
|
||
],
|
||
'handler' => \App\Sockets\TestWebSocket::class,
|
||
],
|
||
],
|
||
```
|
||
|
||
|
||
## 协程
|
||
|
||
> [Swoole原始文档](https://wiki.swoole.com/#/start/coroutine)
|
||
|
||
- 警告:协程下代码执行顺序是乱序的,请求级的数据应该以协程ID隔离,但Laravel/Lumen中存在很多单例、静态属性,不同请求间的数据会相互影响,这是`不安全`的。比如数据库连接就是单例,同一个数据库连接共享同一个PDO资源,这在同步阻塞模式下是没问题的,但在异步协程下是不行的,每次查询需要创建不同的连接,维护不同的IO状态,这就需要用到连接池。
|
||
|
||
- `不要`使用协程,仅`自定义进程`中可使用协程。
|
||
|
||
## 自定义进程
|
||
|
||
> 支持开发者创建一些特殊的工作进程,用于监控、上报或者其他特殊的任务,参考[addProcess](https://wiki.swoole.com/#/server/methods?id=addprocess)。
|
||
|
||
1. 创建Proccess类,实现CustomProcessInterface接口。
|
||
|
||
```php
|
||
namespace App\Processes;
|
||
use App\Tasks\TestTask;
|
||
use Hhxsv5\LaravelS\Swoole\Process\CustomProcessInterface;
|
||
use Hhxsv5\LaravelS\Swoole\Task\Task;
|
||
use Swoole\Coroutine;
|
||
use Swoole\Http\Server;
|
||
use Swoole\Process;
|
||
class TestProcess implements CustomProcessInterface
|
||
{
|
||
/**
|
||
* @var bool 退出标记,用于Reload更新
|
||
*/
|
||
private static $quit = false;
|
||
|
||
public static function callback(Server $swoole, Process $process)
|
||
{
|
||
// 进程运行的代码,不能退出,一旦退出Manager进程会自动再次创建该进程。
|
||
while (!self::$quit) {
|
||
\Log::info('Test process: running');
|
||
// sleep(1); // Swoole < 2.1
|
||
Coroutine::sleep(1); // Swoole>=2.1 已自动为callback()方法创建了协程并启用了协程Runtime,注意所使用的组件与协程兼容性,不兼容时可仅开启部分协程,如:\Swoole\Runtime::enableCoroutine(SWOOLE_HOOK_TCP | SWOOLE_HOOK_SLEEP | SWOOLE_HOOK_FILE);
|
||
// 自定义进程中也可以投递Task,但不支持Task的finish()回调。
|
||
// 注意:修改config/laravels.php,配置task_ipc_mode为1或2,参考 https://wiki.swoole.com/#/server/setting?id=task_ipc_mode
|
||
$ret = Task::deliver(new TestTask('task data'));
|
||
var_dump($ret);
|
||
// 上层会捕获callback中抛出的异常,并记录到Swoole日志,然后此进程会退出,3秒后Manager进程会重新创建进程,所以需要开发者自行try/catch捕获异常,避免频繁创建进程。
|
||
// throw new \Exception('an exception');
|
||
}
|
||
}
|
||
// 要求:LaravelS >= v3.4.0 并且 callback() 必须是异步非阻塞程序。
|
||
public static function onReload(Server $swoole, Process $process)
|
||
{
|
||
// Stop the process...
|
||
// Then end process
|
||
\Log::info('Test process: reloading');
|
||
self::$quit = true;
|
||
// $process->exit(0); // 强制退出进程
|
||
}
|
||
// 要求:LaravelS >= v3.7.4 并且 callback() 必须是异步非阻塞程序。
|
||
public static function onStop(Server $swoole, Process $process)
|
||
{
|
||
// Stop the process...
|
||
// Then end process
|
||
\Log::info('Test process: stopping');
|
||
self::$quit = true;
|
||
// $process->exit(0); // 强制退出进程
|
||
}
|
||
}
|
||
```
|
||
|
||
2. 注册TestProcess。
|
||
|
||
```php
|
||
// 修改文件 config/laravels.php
|
||
// ...
|
||
'processes' => [
|
||
'test' => [ // Key为进程名
|
||
'class' => \App\Processes\TestProcess::class,
|
||
'redirect' => false, // 是否重定向输入输出
|
||
'pipe' => 0, // 管道类型:0不创建管道,1创建SOCK_STREAM类型管道,2创建SOCK_DGRAM类型管道
|
||
'enable' => true, // 是否启用,默认true
|
||
//'num' => 3, // 创建多个进程实例,默认为1
|
||
//'queue' => [ // 启用消息队列作为进程间通信,配置空数组表示使用默认参数
|
||
// 'msg_key' => 0, // 消息队列的KEY,默认会使用ftok(__FILE__, 1)
|
||
// 'mode' => 2, // 通信模式,默认为2,表示争抢模式
|
||
// 'capacity' => 8192, // 单个消息长度,长度受限于操作系统内核参数的限制,默认为8192,最大不超过65536
|
||
//],
|
||
//'restart_interval' => 5, // 进程异常退出后需等待多少秒再重启,默认5秒
|
||
],
|
||
],
|
||
```
|
||
|
||
3. 注意:callback()方法不能退出,如果退出,Manager进程将会重新创建进程。
|
||
|
||
4. 示例:向自定义进程中写数据。
|
||
|
||
```php
|
||
// config/laravels.php
|
||
'processes' => [
|
||
'test' => [
|
||
'class' => \App\Processes\TestProcess::class,
|
||
'redirect' => false,
|
||
'pipe' => 1,
|
||
],
|
||
],
|
||
```
|
||
|
||
```php
|
||
// app/Processes/TestProcess.php
|
||
public static function callback(Server $swoole, Process $process)
|
||
{
|
||
while ($data = $process->read()) {
|
||
\Log::info('TestProcess: read data', [$data]);
|
||
$process->write('TestProcess: ' . $data);
|
||
}
|
||
}
|
||
```
|
||
|
||
```php
|
||
// app/Http/Controllers/TestController.php
|
||
public function testProcessWrite()
|
||
{
|
||
/**@var \Swoole\Process[] $process */
|
||
$customProcesses = \Hhxsv5\LaravelS\LaravelS::getCustomProcesses();
|
||
$process = $customProcesses['test'];
|
||
$process->write('TestController: write data' . time());
|
||
var_dump($process->read());
|
||
}
|
||
```
|
||
|
||
## 常用组件
|
||
|
||
### Apollo
|
||
> 启动`LaravelS`时会获取`Apollo`配置并写入到`.env`文件,同时会启动自定义进程`apollo`用于监听配置变更,当配置发生变更时自动`reload`。
|
||
|
||
1. 启用Apollo组件:启动参数加上`--enable-apollo`以及Apollo的配置参数。
|
||
|
||
```bash
|
||
php bin/laravels start --enable-apollo --apollo-server=http://127.0.0.1:8080 --apollo-app-id=LARAVEL-S-TEST
|
||
```
|
||
|
||
2. 配置热更新(可选的)。
|
||
|
||
```php
|
||
// 修改文件 config/laravels.php
|
||
'processes' => Hhxsv5\LaravelS\Components\Apollo\Process::getDefinition(),
|
||
```
|
||
|
||
```php
|
||
// 当存在其他自定义进程配置时
|
||
'processes' => [
|
||
'test' => [
|
||
'class' => \App\Processes\TestProcess::class,
|
||
'redirect' => false,
|
||
'pipe' => 1,
|
||
],
|
||
// ...
|
||
] + Hhxsv5\LaravelS\Components\Apollo\Process::getDefinition(),
|
||
```
|
||
|
||
3. 可用的参数列表。
|
||
|
||
| 参数名 | 描述 | 默认值 | 示例 |
|
||
| -------- | -------- | -------- | -------- |
|
||
| apollo-server | Apollo服务器URL | - | --apollo-server=http://127.0.0.1:8080 |
|
||
| apollo-app-id | Apollo应用ID | - | --apollo-app-id=LARAVEL-S-TEST |
|
||
| apollo-namespaces | APP所属的命名空间,可指定多个 | application | --apollo-namespaces=application --apollo-namespaces=env |
|
||
| apollo-cluster | APP所属的集群 | default | --apollo-cluster=default |
|
||
| apollo-client-ip | 当前实例的IP,还可用于灰度发布 | 本机内网IP | --apollo-client-ip=10.2.1.83 |
|
||
| apollo-pull-timeout | 拉取配置时的超时时间(秒) | 5 | --apollo-pull-timeout=5 |
|
||
| apollo-backup-old-env | 更新配置文件`.env`时是否备份老的配置文件 | false | --apollo-backup-old-env |
|
||
|
||
### Prometheus
|
||
> 支持Prometheus监控与告警,Grafana可视化查看监控指标。请参考[Docker Compose](https://github.com/hhxsv5/docker)完成Prometheus与Grafana的环境搭建。
|
||
|
||
1. 依赖[APCu >= 5.0.0](https://pecl.php.net/package/apcu)扩展,请先安装它 `pecl install apcu`。
|
||
|
||
2. 拷贝配置文件`prometheus.php`到你的工程`config`目录。视情况修改配置。
|
||
```bash
|
||
# 项目根目录下执行命令
|
||
cp vendor/hhxsv5/laravel-s/config/prometheus.php config/
|
||
```
|
||
如果是`Lumen`工程,还需要在`bootstrap/app.php`中手动加载配置`$app->configure('prometheus');`。
|
||
|
||
3. 配置`全局`中间件:`Hhxsv5\LaravelS\Components\Prometheus\RequestMiddleware::class`。为了尽可能精确地统计请求耗时,`RequestMiddleware`必须作为`第一个`全局中间件,需要放在其他中间件的前面。
|
||
|
||
4. 注册 ServiceProvider:`Hhxsv5\LaravelS\Components\Prometheus\ServiceProvider::class`。
|
||
|
||
5. 在`config/laravels.php`中配置 CollectorProcess 进程,用于定时采集 Swoole Worker/Task/Timer 进程的指标。
|
||
```php
|
||
'processes' => Hhxsv5\LaravelS\Components\Prometheus\CollectorProcess::getDefinition(),
|
||
```
|
||
|
||
6. 创建路由,输出监控指标数据。
|
||
```php
|
||
use Hhxsv5\LaravelS\Components\Prometheus\Exporter;
|
||
|
||
Route::get('/actuator/prometheus', function () {
|
||
$result = app(Exporter::class)->render();
|
||
return response($result, 200, ['Content-Type' => Exporter::REDNER_MIME_TYPE]);
|
||
});
|
||
```
|
||
|
||
7. 完成Prometheus的配置,启动Prometheus。
|
||
```yml
|
||
global:
|
||
scrape_interval: 5s
|
||
scrape_timeout: 5s
|
||
evaluation_interval: 30s
|
||
scrape_configs:
|
||
- job_name: laravel-s-test
|
||
honor_timestamps: true
|
||
metrics_path: /actuator/prometheus
|
||
scheme: http
|
||
follow_redirects: true
|
||
static_configs:
|
||
- targets:
|
||
- 127.0.0.1:5200 # The ip and port of the monitored service
|
||
# Dynamically discovered using one of the supported service-discovery mechanisms
|
||
# https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config
|
||
# - job_name: laravels-eureka
|
||
# honor_timestamps: true
|
||
# scrape_interval: 5s
|
||
# metrics_path: /actuator/prometheus
|
||
# scheme: http
|
||
# follow_redirects: true
|
||
# eureka_sd_configs:
|
||
# - server: http://127.0.0.1:8080/eureka
|
||
# follow_redirects: true
|
||
# refresh_interval: 5s
|
||
```
|
||
|
||
8. 启动Grafana,然后导入[panel json](https://github.com/hhxsv5/laravel-s/tree/PHP-8.x/grafana-dashboard.json)。
|
||
|
||
<img src="https://raw.githubusercontent.com/hhxsv5/laravel-s/PHP-8.x/grafana-dashboard.png" height="800px" alt="Grafana Dashboard">
|
||
|
||
## 其他特性
|
||
|
||
### 配置Swoole事件
|
||
|
||
支持的事件列表:
|
||
|
||
| 事件 | 需实现的接口 | 发生时机 |
|
||
| -------- | -------- | -------- |
|
||
| ServerStart | Hhxsv5\LaravelS\Swoole\Events\ServerStartInterface | 发生在Master进程启动时,`此事件中不应处理复杂的业务逻辑,只能做一些初始化的简单工作` |
|
||
| ServerStop | Hhxsv5\LaravelS\Swoole\Events\ServerStopInterface | 发生在Server正常退出时,`此事件中不能使用异步或协程相关的API` |
|
||
| WorkerStart | Hhxsv5\LaravelS\Swoole\Events\WorkerStartInterface | 发生在Worker/Task进程启动完成后 |
|
||
| WorkerStop | Hhxsv5\LaravelS\Swoole\Events\WorkerStopInterface | 发生在Worker/Task进程正常退出后 |
|
||
| WorkerError | Hhxsv5\LaravelS\Swoole\Events\WorkerErrorInterface | 发生在Worker/Task进程发生异常或致命错误时 |
|
||
|
||
1.创建事件处理类,实现相应的接口。
|
||
```php
|
||
namespace App\Events;
|
||
use Hhxsv5\LaravelS\Swoole\Events\ServerStartInterface;
|
||
use Swoole\Atomic;
|
||
use Swoole\Http\Server;
|
||
class ServerStartEvent implements ServerStartInterface
|
||
{
|
||
public function __construct()
|
||
{
|
||
}
|
||
public function handle(Server $server)
|
||
{
|
||
// 初始化一个全局计数器(跨进程的可用)
|
||
$server->atomicCount = new Atomic(2233);
|
||
|
||
// 控制器中调用:app('swoole')->atomicCount->get();
|
||
}
|
||
}
|
||
```
|
||
|
||
```php
|
||
namespace App\Events;
|
||
use Hhxsv5\LaravelS\Swoole\Events\WorkerStartInterface;
|
||
use Swoole\Http\Server;
|
||
class WorkerStartEvent implements WorkerStartInterface
|
||
{
|
||
public function __construct()
|
||
{
|
||
}
|
||
public function handle(Server $server, $workerId)
|
||
{
|
||
// 初始化一个数据库连接池对象
|
||
// DatabaseConnectionPool::init();
|
||
}
|
||
}
|
||
```
|
||
|
||
2.配置。
|
||
```php
|
||
// 修改文件 config/laravels.php
|
||
'event_handlers' => [
|
||
'ServerStart' => [\App\Events\ServerStartEvent::class], // 按数组顺序触发事件
|
||
'WorkerStart' => [\App\Events\WorkerStartEvent::class],
|
||
],
|
||
```
|
||
|
||
### Serverless
|
||
|
||
#### 阿里云函数计算
|
||
> [函数计算官方文档](https://help.aliyun.com/product/50980.html)。
|
||
|
||
1.修改`bootstrap/app.php`,设置storage目录。因为项目目录只读,`/tmp`目录才可读写。
|
||
|
||
```php
|
||
$app->useStoragePath(env('APP_STORAGE_PATH', '/tmp/storage'));
|
||
```
|
||
|
||
2.创建Shell脚本`laravels_bootstrap`,并赋予`可执行权限`。
|
||
|
||
```bash
|
||
#!/usr/bin/env bash
|
||
set +e
|
||
|
||
# 创建storage相关目录
|
||
mkdir -p /tmp/storage/app/public
|
||
mkdir -p /tmp/storage/framework/cache
|
||
mkdir -p /tmp/storage/framework/sessions
|
||
mkdir -p /tmp/storage/framework/testing
|
||
mkdir -p /tmp/storage/framework/views
|
||
mkdir -p /tmp/storage/logs
|
||
|
||
# 设置环境变量APP_STORAGE_PATH,请确保与.env的APP_STORAGE_PATH一样
|
||
export APP_STORAGE_PATH=/tmp/storage
|
||
|
||
# Start LaravelS
|
||
php bin/laravels start
|
||
```
|
||
|
||
3.配置`template.xml`。
|
||
|
||
```xml
|
||
ROSTemplateFormatVersion: '2015-09-01'

## 注意事项
|
||
|
||
### 单例问题
|
||
|
||
- 传统FPM下,单例模式的对象的生命周期仅在每次请求中,请求开始=>实例化单例=>请求结束后=>单例对象资源回收。
|
||
|
||
- Swoole Server下,所有单例对象会常驻于内存,这个时候单例对象的生命周期与FPM不同,请求开始=>实例化单例=>请求结束=>单例对象依旧保留,需要开发者自己维护单例的状态。
|
||
|
||
- 常见的解决方案:
|
||
|
||
1. 写一个`XxxCleaner`清理器类来清理单例对象状态,此类需实现接口`Hhxsv5\LaravelS\Illuminate\Cleaners\CleanerInterface`,然后注册到`laravels.php`的`cleaners`中。
|
||
|
||
2. 用一个`中间件`来`重置`单例对象的状态。
|
||
|
||
3. 如果是以`ServiceProvider`注册的单例对象,可添加该`ServiceProvider`到`laravels.php`的`register_providers`中,这样每次请求会重新注册该`ServiceProvider`,重新实例化单例对象,[参考](https://github.com/hhxsv5/laravel-s/blob/PHP-8.x/Settings-CN.md#register_providers)。

|
||
|
||
### 调试方式
|
||
|
||
- 记录日志;如想要在控制台输出,可使用`stderr`,Log::channel('stderr')->debug('debug message')。
|
||
|
||
- [Laravel Dump Server](https://github.com/beyondcode/laravel-dump-server)(Laravel 5.7已默认集成)。
|
||
|
||
### 读取请求
|
||
应通过`Illuminate\Http\Request`对象来读取请求信息,$_ENV是可读取的,$_SERVER是部分可读的,`不能使用`$_GET、$_POST、$_FILES、$_COOKIE、$_REQUEST、$_SESSION、$GLOBALS。
|
||
|
||
```php
|
||
public function form(\Illuminate\Http\Request $request)
|
||
{
|
||
$name = $request->input('name');
|
||
$all = $request->all();
|
||
$sessionId = $request->cookie('sessionId');
|
||
$photo = $request->file('photo');
|
||
// 调用getContent()来获取原始的POST body,而不能用file_get_contents('php://input')
|
||
$rawContent = $request->getContent();
|
||
//...
|
||
}
|
||
```
|
||
|
||
### 输出响应
|
||
推荐通过返回`Illuminate\Http\Response`对象来响应请求,兼容echo、vardump()、print_r(),`不能使用`函数 dd()、exit()、die()、header()、setcookie()、http_response_code()。
|
||
|
||
```php
|
||
public function json()
|
||
{
|
||
return response()->json(['time' => time()])->header('header1', 'value1')->withCookie('c1', 'v1');
|
||
}
|
||
```
|
||
|
||
### 持久连接
|
||
`单例的连接`将被常驻内存,建议开启`持久连接`,获得更好的性能。
|
||
1. 数据库连接,连接断开后会自动重连
|
||
|
||
```php
|
||
// config/database.php
|
||
'connections' => [
|
||
'my_conn' => [
|
||
'driver' => 'mysql',
|
||
'host' => env('DB_MY_CONN_HOST', 'localhost'),
|
||
'port' => env('DB_MY_CONN_PORT', 3306),
|
||
'database' => env('DB_MY_CONN_DATABASE', 'forge'),
|
||
'username' => env('DB_MY_CONN_USERNAME', 'forge'),
|
||
'password' => env('DB_MY_CONN_PASSWORD', ''),
|
||
'charset' => 'utf8mb4',
|
||
'collation' => 'utf8mb4_unicode_ci',
|
||
'prefix' => '',
|
||
'strict' => false,
|
||
'options' => [
|
||
// 开启持久连接
|
||
\PDO::ATTR_PERSISTENT => true,
|
||
],
|
||
],
|
||
],
|
||
```
|
||
|
||
2. Redis连接,连接断开后`不会立即`自动重连,会抛出一个关于连接断开的异常,下次会自动重连。需确保每次操作Redis前正确的`SELECT DB`。
|
||
|
||
```php
|
||
// config/database.php
|
||
'redis' => [
|
||
'client' => env('REDIS_CLIENT', 'phpredis'), // 推荐使用phpredis,以获得更好的性能
|
||
'default' => [
|
||
'host' => env('REDIS_HOST', 'localhost'),
|
||
'password' => env('REDIS_PASSWORD', null),
|
||
'port' => env('REDIS_PORT', 6379),
|
||
'database' => 0,
|
||
'persistent' => true, // 开启持久连接
|
||
],
|
||
],
|
||
```
|
||
|
||
### 关于内存泄露
|
||
|
||
- 避免使用全局变量,如一定要,请手动清理或重置。
|
||
|
||
- 无限追加元素到全局变量、静态变量、单例,将导致内存溢出。
|
||
|
||
```php
|
||
class Test
|
||
{
|
||
public static $array = [];
|
||
public static $string = '';
|
||
}
|
||
|
||
// 某控制器
|
||
public function test(Request $req)
|
||
{
|
||
// 内存溢出
|
||
Test::$array[] = $req->input('param1');
|
||
Test::$string .= $req->input('param2');
|
||
}
|
||
```
|
||
|
||
- 内存泄露的检测方法
|
||
|
||
1. 修改`config/laravels.php`:`worker_num=1, max_request=1000000`,测试完成后记得改回去;
|
||
|
||
2. 增加路由`/debug-memory-leak`,不设置任何`路由中间件`,用于观察`Worker`进程的内存变化情况;
|
||
|
||
```php
|
||
Route::get('/debug-memory-leak', function () {
|
||
global $previous;
|
||
$current = memory_get_usage();
|
||
$stats = [
|
||
'prev_mem' => $previous,
|
||
'curr_mem' => $current,
|
||
'diff_mem' => $current - $previous,
|
||
];
|
||
$previous = $current;
|
||
return $stats;
|
||
});
|
||
```
|
||
|
||
3. 启动`LaravelS`,请求`/debug-memory-leak`,直到`diff_mem`小于或等于零;如果`diff_mem`一直大于零,说明`全局中间件`或`Laravel框架`可能存在内存泄露;
|
||
|
||
4. 完成`步骤3`后,`交替`请求业务路由与`/debug-memory-leak`(建议使用`ab`/`wrk`对业务路由进行大量的请求),刚开始出现的内存增涨是正常现象。业务路由经过大量请求后,如果`diff_mem`一直大于零,并且`curr_mem`持续增大,则大概率存在内存泄露;如果`curr_mem`始终在一定范围内变化,没有持续变大,则大概率不存在内存泄露。
|
||
|
||
5. 如果始终没法解决,[max_request](https://wiki.swoole.com/#/server/setting?id=max_request)是最后兜底的方案。
