nginx配置成系统服务 systemctl

(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

（4）Nginx命令配置到系统环境

(1)修改/etc/profile文件

vim /etc/profile
在最后一行添加
export PATH=$PATH:/usr/local/nginx/sbin

source /etc/profile

(3)执行nginx命令

nginx -V
