报错信息 [root@controller ~]# openstack-service status | grep failed MainPID=0 Id=neutron-server.service
但是通过systemctl show --property MainPID 命令只能获取最左边的父进程ID....怎么样通过这个MainPID获取实际工作的子进程ID呢，ps的 -g选项可以根据PID过程要显示的所有属于指定PID的进程及子进程，比如： $ ps --forest -o pid,cmd -g 1088.../bin/bash # 获取服务的MainPID,$service_name 为服务名称 main_pid="$(systemctl show $service_name --property=MainPID
