swoole 命令查看进程的对应程序

[zhengzongqiang@localhost ~]$ ps aft | grep http
 40193 pts/2    S+     0:00  \_ grep --color=auto http
 39658 pts/1    Sl+    0:00      \_ /opt/soft/php/bin/php /opt/work/htdocs/swoole_mooc/demo/process/../server/http.php
 39659 pts/1    S+     0:00          \_ /opt/soft/php/bin/php /opt/work/htdocs/swoole_mooc/demo/process/../server/http.php
 39661 pts/1    S+     0:00              \_ /opt/soft/php/bin/php /opt/work/htdocs/swoole_mooc/demo/process/../server/http.php

我们可以看到，http进程ID为39659，其父进程ID为39658进程，即swoole_process进程，再父进程就是启动swoole_process进程的进程，即执行此文件的的命令的进程，即39657进程。
39659进程也有子进程，即worker进程。
可以理解为39658进程为master进程，39659进程为manager进程。
