前言
本文主要给大家介绍了关于Yii2结合Workerman的websocket的相关内容，两者都是好东西，我就想着能不能结合起来，这样Yii2出现瓶颈的时候有些业务就可以平滑地迁移到Workerman中。下面话不多说了，来随着小编来一起看看详细的介绍吧
步骤如下
1、安装workerman
代码语言：javascript复制composer require workerman/workerman2、启动workerman
创建commands/WorkermanWebSocketController.php文件
创建actionIndex()函数，用来启动，代码如下
代码语言：javascript复制public function actionIndex()
{
if ('start' == $this- send) {
try {
$this- start($this- daemon);
} catch (Exception $e) {
$this- stderr($e- getMessage() . "n", Console::FG_RED);
}
} else if ('stop' == $this- send) {
$this- stop();
} else if ('restart' == $this- send) {
$this- restart();
} else if ('reload' == $this- send) {
$this- reload();
} else if ('status' == $this- send) {
$this- status();
} else if ('connections' == $this- send) {
$this- connections();
}
}添加初始化模块
代码语言：javascript复制public function initWorker()
{
$ip = isset($this- config['ip']) ? $this- config['ip'] : $this- ip;
$port = isset($this- config['port']) ? $this- config['port'] : $this- port;
$wsWorker = new Worker("websocket://{$ip}:{$port}");
// 4 processes
$wsWorker- count = 4;
// Emitted when new connection come
$wsWorker- onConnect = function ($connection) {
echo "New connectionn";
};
// Emitted when data received
$wsWorker- onMessage = function ($connection, $data) {
// Send hello $data
$connection- send('hello ' . $data);
};
// Emitted when connection closed
$wsWorker- onClose = function ($connection) {
echo "Connection closedn";
};
}添加启动模块
代码语言：javascript复制/**
* workman websocket start
*/
public function start()
{
$this- initWorker();
// 重置参数以匹配Worker
global $argv;
$argv[0] = $argv[1];
$argv[1] = 'start';
if ($this- daemon) {
$argv[2] = '-d';
}
// Run worker
Worker::runAll();
}添加停止模块
代码语言：javascript复制/**
* workman websocket stop
*/
public function stop()
{
$this- initWorker();
// 重置参数以匹配Worker
global $argv;
$argv[0] = $argv[1];
$argv[1] = 'stop';
if ($this- gracefully) {
$argv[2] = '-g';
}
// Run worker
Worker::runAll();
}添加重启模块
代码语言：javascript复制/**
* workman websocket restart
*/
public function restart()
{
$this- initWorker();
// 重置参数以匹配Worker
global $argv;
$argv[0] = $argv[1];
$argv[1] = 'restart';
if ($this- daemon) {
$argv[2] = '-d';
}
if ($this- gracefully) {
$argv[2] = '-g';
}
// Run worker
Worker::runAll();
}添加重载模块
代码语言：javascript复制/**
* workman websocket reload
*/
public function reload()
{
$this- initWorker();
// 重置参数以匹配Worker
global $argv;
$argv[0] = $argv[1];
$argv[1] = 'reload';
if ($this- gracefully) {
$argv[2] = '-g';
}
// Run worker
Worker::runAll();
}添加状态模块
代码语言：javascript复制/**
* workman websocket status
*/
public function status()
{
$this- initWorker();
// 重置参数以匹配Worker
global $argv;
$argv[0] = $argv[1];
$argv[1] = 'status';
if ($this- daemon) {
$argv[2] = '-d';
}
// Run worker
Worker::runAll();
}添加链接数模块
代码语言：javascript复制/**
* workman websocket connections
*/
public function connections()
{
$this- initWorker();
// 重置参数以匹配Worker
global $argv;
$argv[0] = $argv[1];
$argv[1] = 'connections';
// Run worker
Worker::runAll();
}3、前端调用
代码语言：javascript复制<script
// Create WebSocket connection.
const ws = new WebSocket('ws://{{ app.request.hostName }}:2347/'); // 这里是获取的网站的域名，测试的时候可以改为自己的本地的ip地址
// Connection opened
ws.addEventListener('open', function (event) {
ws.send('Hello Server!');
});
// Listen for messages
ws.addEventListener('message', function (event) {
console.log('Message from server ', event.data);
});
setTimeout(function() {
ws.send('ssssss');
}, 10000);
</script 4、config参数配置
修改console.php并添加如下代码
代码语言：javascript复制'controllerMap' = [
'workerman-web-socket' = [
'class' = 'appcommandsWorkermanWebSocketController',
'config' = [
'ip' = '127.0.0.1',
'port' = '2346',
'daemonize' = true,
],
],
],5、nginx配置
为什么会用 nginx， 我们正常部署上线是不可能直接使用ip的，这个户存在安全隐患，最好是绑定一个域名
代码语言：javascript复制server {
charset utf-8;
client_max_body_size 128M;
listen 2347;
server_name www.gowhich.com; # 这里改为自己的域名
access_log /xxx.workerman.access.log; # 换成自己服务器的nginx日志路径
error_log /xxx.workerman.error.log; # 换成自己服务器的nginx日志路径
location / {
proxy_pass http://127.0.0.1:2346; # 代理2346 也可以根据项目配置为自己的端口
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}重新nginx
代码语言：javascript复制nginx -s relad 或者 sudo nginx -s reload然后将第3步的代码加入自己做的视图中，如果没有问题的话，websocket启动后就能正常通讯了。
6、启动workerman websocket
代码语言：javascript复制// 启动
./yii workerman-web-socket -s start -d如果没有问题的话会得到类似如下的结果
代码语言：javascript复制$ ./yii workerman-web-socket -s start -d
Workerman[workerman-web-socket] start in DAEMON mode
----------------------- WORKERMAN -----------------------------
Workerman version:3.5.13 PHP version:7.1.16
------------------------ WORKERS -------------------------------
user worker listen processes status
durban none websocket://127.0.0.1:2346 4 [OK]
----------------------------------------------------------------
Input "php workerman-web-socket stop" to stop. Start success.7、其他
commands/WorkermanWebSocketController.php 完整代码如下
