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.servicesystemctl start nginx.servicesystemctl 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
