nginx ---- 配置成系统服务

把Nginx应用服务设置成为系统服务，方便对Nginx服务的启动和停止等相关操作，具体实现步骤:

(1) 在/usr/lib/systemd/system目录下添加nginx.service,内容如下:

vim /usr/lib/systemd/system/nginx.service

[Unit]
Description=nginx web service
documentation=http://nginx.org/en/docs/
After=network.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
ExecStart=/usr/local/nginx/sbin/nginx
ExecReload=/usr/local/nginx/sbin/nginx -s reload
ExecStop=/usr/local/nginx/sbin/nginx -s stop
PrivateTmp=true

[Install]
WantedBy=default.target

(2)添加完成后如果权限有问题需要进行权限设置

chmod 755 /usr/lib/systemd/system/nginx.service

(3)使用系统命令来操作Nginx服务

启动: systemctl start nginx
停止: systemctl stop nginx
重启: systemctl restart nginx
重新加载配置文件: systemctl reload nginx
查看nginx状态: systemctl status nginx
开机启动: systemctl enable nginx
