我这个菜鸟。。。。。还在挣扎中

这坑啊，爬了一天

直接给出脚本了

主要的也就这几个脚本，感觉安装的Nagios监控服务还有点问题

少了nrpe模块还没有搞定，慢慢来嘛 - -

脚本自己写的

这里给出几个可能错误的原因：

502 Bad Gateway（看nginx日志，很重要，里面有你想要的答案）

请检查php服务是否开启（php-fpm）

请检查perl-fcgi是否OK（可能是权限问题，nginx的user没有/bin/bash权限，修改/etc/passwd文件里面的nginx用户bash）

403 （查看Nagios的日志）

还是各种权限问题，或者nginx的根目录有点问题，用这个脚本我是没碰到过这种错误，但是前面手动安装的时候出现过

参考：一键安装LNMP脚本

我只是他们的搬运工- - 、、、、、、、、、、、

这里只是一个模版，可以自行修改脚本
