nginx开机自启动init脚本

适用于源码编译安装nginx的用户，支持RedHat、CentOS、Debian、Ubuntu等发行版，支持start|stop|restart|reload 四个基本操作，非常简单实用。

一、使用方法

1、安装

        
        bash
    
wget http://www.wangyan.cloud/download/conf/init.d.nginx -P /etc/init.d/nginx
chmod 755  /etc/init.d/nginx
chkconfig --add nginx (RedHat)
update-rc.d -f nginx defaults (debian)

2、卸载

        
        bash
    
chkconfig --del nginx (RedHat)
update-rc.d -f nginx remove (debian)

3、使用实例

        
        bash
    
service nginx stop
service nginx start
service nginx restart
service nginx reload
