Laravel workerman 创建并实时聊天 操作文档
1. 安装composer require workerman/workerman
2. 运行php artisan workerman start
3. 以daemon（守护进程）方式启动php artisan workerman start-d
4. php artisan workerman reload // 重新加载配置
5. php artisan workerman reload // 重启workerman
6. php artisan workerman stop // 停止workerman
7. workerman创建php artisan make:command 文件名
8. 修改文件protected $signature = '进程名 {action}';
9. workerman注册Kernel.php protected $commands = [文件类];
