CentOS7查看systemctl 控制的服务的相关配置

例如，启动配置文件

[root@Docker_Machine_192.168.31.130 ~]# systemctl show --property=FragmentPath docker 
FragmentPath=/usr/lib/systemd/system/docker.service
[root@Docker_Machine_192.168.31.130 ~]# systemctl  show docker  | grep  FragmentPath  
FragmentPath=/usr/lib/systemd/system/docker.service
