Nginx启动、关闭、重新加载脚本

#! /bin/sh

　　备注：着红色的地方要根据实际路径进行修改，将上述脚本命名为nginx，保存到/etc/init.d目录下。尝试/etc/init.d/nginx start 命令，会报“权限不足”的错误，执行chmod +x /etc/init.d/nginx 给其赋执行权限。

可以用一下方式来执行此脚本：

/etc/init.d/nginx start

/etc/init.d/nginx sttop

/etc/init.d/nginx reload

/etc/init.d/nginx restart

如果想让此脚本开机自启动  还需在脚本头部家 chkconfig xx  xx等注释（具体需要参考chkconfig命令用法），让它支持chckconfig  然后执行/sbin/chkconfig nginx on 命令。同时，可以sudo /sbin/chkconfig --list nginx  来查看效果。
