centos7 设置 查看 开机 启动项

1.查看开机自启项
centos7自启项已不用chkconfig改为：
systemctl list-unit-files
左边是服务名称，右边是状态，enabled是开机启动，disabled是开机不启动。

当然还可以过滤一下 比如：查看启动项
systemctl list-unit-files | grep enable

2.设置开机自启项
systemctl enable redis
systemctl enable nginx.service

启动nginx
systemctl start nginx.service

结束nginx
systemctl stop nginx.service

重启nginx
systemctl restart nginx.service
