【Linux笔记】CentOS 7 systemctl、firewalld

一、CentOS7 systemctl

在CentOS7中,进行chkconfig命令操作时会发现有类似“systemctl.....”的提示,systemctl可以简单实现service和chkconfig的结合,这样通过一个命令就可以实现两个命令的功能。

systemctl命令的基本操作格式是:

systemctl [OPTIONS...]  {COMMAND}...

以nginx服务为例,实现停止、启动、重启的动作如下:

systemctl stop    nginx.service
systemctl start   nginx.service
systemctl restart nginx.service

检查服务状态

systemctl status nginx.service

使服务开机启动

systemctl enable nginx.service

取消服务开机启动

systemctl disable nginx.service

二、CentOS 7 firewalld
