[系统运维]systemctl命令管理nginx

编译安装的nginx要使用/usr/local/nginx/sbin/nginx -s reload和/usr/local/nginx/sbin/nginx -s stop来重启和停止十分麻烦。现在我们来使用system来管理

一、在/lib/systemd/system/创建文件

[root@localhost ~]# vi /lib/systemd/system/nginx

二、新建文件写入

##配置参数解释##
[Unit]
Description=nginx                             ##描述
After=network.target                          ##描述服务类别，网络服务模式
[Service]
Type=forking                                  ##后台运行形式
PIDFile=/usr/local/nginx/logs/nginx.pid       ##PID文件位置 ，记录进程号 
ExecStart=/usr/local/nginx/sbin/nginx         ##启动服务脚本
ExecReload=/usr/bin/kill -s HUP $MAINPID      ##根据PID（nginx进程号）重载配置
ExecStop=/usr/bin/kill -s QUIT $MAINPID       ##根据PID（nginx进程号）终止进程
PrivateTmp=true
[Install]
WantedBy=multi-user.target

三、刷新

 [root@localhost]#systemctl daemon-reload

四、启动并查看状态

[root@localhost]# systemctl start nginx
[root@localhost]# systemctl status nginx
