Centos 7启动命令发生了很大的变化

设置开机自启动

systemctl enable nfs-server.service

下面以nfs服务为例:

1.启动nginx服务

systemctl start nfs-server.service

2.设置开机自启动

systemctl enable nfs-server.service

3.停止开机自启动

systemctl disable nfs-server.service

4.查看服务当前状态

systemctl status nfs-server.service

5.重新启动某服务

systemctl restart nfs-server.service

6.查看所有已启动的服务

systemctl list -units --type=service
