一、安装 官方手册
http://doc.workerman.net/315116
1.1、 安装错误:
WARNING: channel "pecl.php.net" has updated its protocols, use "pecl channel-update pecl.php.net" to update
解决办法：
pecl channel-update pecl.php.net
1.2 错误：

ERROR: failed to run `phpize'
解决办法：
popen readlink putenv三个函数在php.ini里将popen函数禁用了
或者在这里添加
disable_functions中去掉对应三个函数，重启服务
1.3 继续安装 pecl install event （重点关注1.2.3地方输入的值）
三个地方按上面来操作
二 安装Event扩展
注意目前libevent扩展不支持php7，php7用户只能使用Event扩展。
yum install libevent-devel
pecl install channel://pecl.php.net/libevent-0.1.0 //提示libevent installation [autodetect]: 时按回车
echo extension=libevent.so > /etc/php.d/libevent.ini
四、测试是否成功
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">
<title>Title</title>
</head>
<body>
<script>
ws = new WebSocket("wss://www.xxxx.com:2xxx");
ws.onopen = function() {
alert("连接成功");
ws.send('tom');
alert("给服务端发送一个字符串：tom");
};
ws.onmessage = function(e) {
alert("收到服务端的消息：" + e.data);
};
</script>
</body>
</html>
注意：每次修改Workerman,都要重新启动
五、Workerman TP5 php代码测试启动
要启动Workerman，首先需要有一个启动入口文件，里面定义了服务监听的端口及协议。
可以参考入门指引--简单开发实例部分
这里以我们自己的项目为例，它的启动入口为server.php。
server.php文件是自己写的php文件,路径放到项目中，
<?php
define('APP_PATH', __DIR__ . '/application/');
define('BIND_MODULE','push/Worker');
// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';
?>
进入项目根目录后再命令启动
宝塔操作方法：
启动
以debug（调试）方式启动
php server.php start
以daemon（守护进程）方式启动
php server.php start -d
停止
php server.php stop
重启
php start.php restart
平滑重启
php server.php reload
查看状态
php server.php status
4.1 错误:pcntl_fork() has been disabled for security reasons in file
由于安全原因，pcntl_fork()在第1515行文件/xxxxxx/vendor/workerman/workerman/Worker.php中被禁用
四、给Workerman 配置SSL证书，就是域名那个SSL证书
创建wss服务
问：
Workerman如何创建一个wss服务，使得客户端可以用过wss协来连接通讯，比如在微信小程序中连接服务端。
答：
wss协议实际是websocket+SSL，就是在websocket协议上加入SSL层，类似https(http+SSL)。 所以只需要在websocket协议的基础上开启SSL即可支持wss协议。
方法一 ，直接用Workerman开启SSL
准备工作：
1、Workerman版本不小于3.3.7
2、PHP安装了openssl扩展
3、已经申请了证书（pem/crt文件及key文件）放在磁盘任意目录
代码：
<?php
require_once __DIR__ . '/Workerman/Autoloader.php';
use Workerman\Worker;
// 证书最好是申请的证书
$context = array(
// 更多ssl选项请参考手册 http://php.net/manual/zh/context.ssl.php
'ssl' => array(
// 请使用绝对路径
'local_cert' => '磁盘路径/server.pem', // 也可以是crt文件
'local_pk' => '磁盘路径/server.key',
'verify_peer' => false,
// 'allow_self_signed' => true, //如果是自签名证书需要开启此选项
)
);
// 这里设置的是websocket协议（端口任意，但是需要保证没被其它程序占用）
$worker = new Worker('websocket://0.0.0.0:443', $context);
// 设置transport开启ssl，websocket+ssl即wss
$worker->transport = 'ssl';
$worker->onMessage = function($con, $msg) {
$con->send('ok');
};
Worker::runAll();
参考：http://doc.workerman.net/faq/secure-websocket-server.html
在代码中配置对应SSL证书的路径：
4.1 把证书上传到宝塔SSL证书路径/www/server/panel/vhost/ssl/www.xxx.com/
名称与后缀修改成下面这样子
密钥： privkey.pem
fullchain.pem
4.2 修改代码中证书路径：\vendor\topthink\think-worker\src\Server.php
