首先是先安装

composer require workerman/gateway-worker
composer require workerman/gatewayclient

下载demo

服务器开通TCP端口8282、1238

将Applications\YourApp目录随便放ThinkPHP6的哪个位置，我这里放在了app\gateway\ws目录中
配置composer.json

"autoload": {"psr-4": {"app\\": "app","": "app/gateway/ws" # 增加这一行},"psr-0": {"": "extend/"}},

保存后执行composer dumpautoload更新

将Events.php、start_businessworker.php、start_gateway.php和 start_register.php文件中的require_once __DIR__ . '/../../vendor/autoload.php';删除

修改start_gateway.php文件，设置ssl

// 证书最好是申请的证书
$context = array(// 更多ssl选项请参考手册 https://php.net/manual/zh/context.ssl.php'ssl' => array(// 请使用绝对路径'local_cert' => '/www/wwwroot/xxx.xxx.com/app/gateway/ws/ssl/server.pem', // 也可以是crt文件'local_pk' => '/www/wwwroot/xxx.xxx.com/app/gateway/ws/ssl/server.key','verify_peer' => false,// 'allow_self_signed' => true, //如果是自签名证书需要开启此选项)
);
// websocket协议(端口任意，只要没有被其它程序占用就行)
$gateway = new Gateway("websocket://0.0.0.0:8282", $context);
// 开启SSL，websocket+SSL 即wss
$gateway->transport = 'ssl';// gateway 进程，这里使用Text协议，可以用telnet测试
//$gateway = new Gateway("text://0.0.0.0:8282");

使用ThinkPHP6的自定义命令开启服务

php think make:command Ws 

Ws.php内容

<?php
declare (strict_types=1);namespace app\command;use think\console\Command;
use think\console\Input;
use think\console\input\Argument;
use think\console\input\Option;
use think\console\Output;
use Workerman\Worker;class Ws extends Command
{protected function configure(){// 指令配置$this->setName('ws')->addArgument('action', Argument::OPTIONAL, "start|stop|restart|reload|status|connections", 'start')->addOption('mode', 'm', Option::VALUE_OPTIONAL, 'Run the workerman server in daemon mode.')->setDescription('workerman');}protected function execute(Input $input, Output $output){$action = $input->getArgument('action');$mode = $input->getOption('mode');// 重新构造命令行参数,以便兼容workerman的命令global $argv;$argv = [];array_unshift($argv, 'think', $action);if ($mode == 'd') {$argv[] = '-d';} else if ($mode == 'g') {$argv[] = '-g';}// 检查扩展if (!extension_loaded('pcntl')) {exit("Please install pcntl extension. See http://doc3.workerman.net/appendices/install-extension.html\n");}if (!extension_loaded('posix')) {exit("Please install posix extension. See http://doc3.workerman.net/appendices/install-extension.html\n");}// 标记是全局启动define('GLOBAL_START', 1);foreach (glob(app()->getBasePath() . '/gateway/*/start*.php') as $start_file) {require_once $start_file;}Worker::runAll();}
}

配置自定义指令，在config/console.php中增加

<?php
// +----------------------------------------------------------------------
// | 控制台配置
// +----------------------------------------------------------------------
return [// 指令定义'commands' => ['ws' => \app\command\Ws::class # 增加],
];

命令启动服务

# debug启动
php think ws start 
# 守护进程启动
php think ws start --mode d
# 停止服务
php think ws stop

我是docker配置的环境，报错了Please install pcntl extension.
因为pcntl是php自带的扩展，所以只要执行命令安装一下就可以

docker-php-ext-install pcntl  

如果没有执行composer dumpautoload运行时可能会报错：Waring: Events::onMessage is not callable
