1、服务器与被监控主机安装组件

   yum install bc

   编译安装nrpe（参考教程：http://2860664.blog.51cto.com/2850664/1559056）

以下为被监控主机设置

2、下载监控脚本 check_nginx.sh，并上传到被监控主机的 /usr/local/nagios/libexec目录

   下载地址：http://exchange.nagios.org/components/com_mtree/p_w_upload.php?link_id=622&cf_id=24

   给予脚本可执行权限

   chmod +x /usr/local/nagios/libexec/check_nginx.sh

3、vi /usr/local/nagios/etc/nrpe.cfg  添加

   command[check_nginx]=/usr/local/nagios/libexec/check_nginx.sh -H www.xxx.com -P 80 -p /usr/local/nginx/logs/ -n nginx.pid -s nginx_status -w 15000 -c 20000

   其中红色为你要监控的网站；

   绿色为nginx.pid的保存路径，可以在nginx.conf中添加：pid        /usr/local/nginx/logs/nginx.pid;进行设置，切记。

4、测试脚本运行

   cd /usr/local/nagios/libexec

   ./check_nginx.sh -H www.xxx.com -P 80 -p /usr/local/nginx/logs/ -n nginx.pid -s nginx_status -w 15000 -c 20000

OK - nginx is running. 1 requests per second, 1 connections per second (1.00 requests per connection) | 'reqpsec'=1 'conpsec'=1 'conpreq'=1.00 ]

以下为监控主机设置

5、vi /usr/local/nagios/etc/nagios.cfg  添加

   cfg_file=/usr/local/nagios/etc/objects/nginx.cfg

6、touch /usr/local/nagios/etc/objects/nginx.cfg

   vi /usr/local/nagios/etc/objects/nginx.cfg  （注意修改被监控端的IP）内容如下
