程序代码

DEBUG模式正常，如下所示

Workerman[worker_think.php] start in DEBUG mode
------------------------------------------- WORKERMAN --------------------------------------------
Workerman version:4.0.19          PHP version:5.4.45
-------------------------------------------- WORKERS ---------------------------------------------
proto   user            worker          listen                      processes    status           
ssl     root            none            websocket://0.0.0.0:1234    1             [OK]            
--------------------------------------------------------------------------------------------------

DAEMON模式也成功启动，如下所示

[root@VM-20-191-centos wmserver]# php worker_think.php start -d
Workerman[worker_think.php] start in DAEMON mode
------------------------------------------- WORKERMAN --------------------------------------------
Workerman version:4.0.19          PHP version:5.4.45
-------------------------------------------- WORKERS ---------------------------------------------
proto   user            worker          listen                      processes    status           
ssl     root            none            websocket://0.0.0.0:1234    1             [OK]            
--------------------------------------------------------------------------------------------------
Input "php worker_think.php stop" to stop. Start success.

status却是not run，实际也无法通信

[root@VM-20-191-centos wmserver]# php worker_think.php status
Workerman[worker_think.php] status 
Workerman[worker_think.php] not run
