1、安裝所需組件
yum install perl perl-devel perl-CPAN bc perl-Time-HiRes
perl -MCPAN -eshell
cpan> install Bundle::LWP
編譯安裝nrpe（參考教程：http://2860664.blog.51cto.com/2850664/1559056）
以下是被監控端設置
2、下載check_nginx_status.pl腳本
下載地址：https://codeload.github.com/regilero/check_nginx_status/zip/master
解壓文件後，上傳check_nginx_status.pl到/usr/local/nagios/libexec
chmod +x check_nginx_status.pl
chown nagios.nagcmd check_nginx_status.pl
3、vi /usr/local/nginx/conf/nginx.conf 在需要監控的虛擬主機下加入
location /nginx_status {
stub_status on;
allow 192.168.1.247;
access_log off;
}3、在被監控端測試腳本
cd /usr/local/nagios/libexec
./check_nginx_status.pl -H 192.168.1.247 -s www.xxx.com -P 80
NGINX OK - 0.067 sec. response time, Active: 1 (Writing: 1 Reading: 0 Waiting: 0) ReqPerSec: 0.111 ConnPerSec: 0.111 ReqPerConn: 1.000|Writing=1;;;; Reading=0;;;; Waiting=0;;;; Active=1;;;; ReqPerSec=0.111111;;;; ConnPerSec=0.111111;;;; ReqPerConn=1.000000;;;;
其中紅色爲nginx服務器的IP地址；綠色爲需要監控的網站網址。
4、vi /usr/local/nagios/etc/nrpe.cfg 添加
command[check_nginx]=/usr/local/nagios/libexec/check_nginx_status.pl -H 192.168.1.247 -s www.xxx.com -P 80
5、刪除/tmp生成的192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9不然後面後報錯！提示無法生成文件。
rm /tmp/192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9
以下是nagios主機的設置
5、服務器端測試
/usr/local/nagios/libexec/check_nrpe -H 192.168.1.247 -c check_nginx
NGINX OK - 0.065 sec. response time, Active: 1 (Writing: 1 Reading: 0 Waiting: 0) ReqPerSec: 0.020 ConnPerSec: 0.020 ReqPerConn: 1.000|Writing=1;;;; Reading=0;;;; Waiting=0;;;; Active=1;;;; ReqPerSec=0.020000;;;; ConnPerSec=0.020000;;;; ReqPerConn=1.000000;;;;
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 （注意修改被監控端的IP）內容如下

報錯信息
7、nagios服務器報錯
NGINX UNKNOWN - unable to write temporary data in:/tmp/192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9
解決方法：刪除被監控主機/tmp下的文件192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9
rm /tmp/192.168.1.247_check_nginx_status8d727909e5ace94dc547c3af50af6cb9
