把下面的代码保存为nginx 没有后缀名的文件

放在/etc/init.d/nginx 文件里面

3.设置权限并启动nginx ：

chmod 755 /etc/init.d/nginx

/etc/init.d/nginx start

//添加为系统服务

chkconfig –add nginx

//查看服务拉几个模式开启了次服务

chkconfig –list nginx

//下面是开启345模式启动php-fpm 就是系统自动启动的时候自动开启此服务

chkconfig –level 345 nginx on

最后，给出nginx 以服务的方式启动、停止和重启：

service nginx start

service nginx stop

service nginx reload

#!/bin/sh

# chkconfig:   - 85 15
