安装Nagios-plugin：
[root@localhost software]# tar -zxvf nagios-plugins-1.4.15.tar.gz &>/dev/null
[root@localhost software]# cd nagios-plugins-1.4.15
[root@localhost nagios-plugins-1.4.15]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --enable-perl-modules
[root@localhost nagios-plugins-1.4.15]# make &&make install
[root@localhost software]# ls /usr/local/nagios/libexec/|wc -l

[root@localhost software]#
安装NRPE：
[root@localhost software]# yum -y install openssl openssl-devel
[root@localhost software]# tar -zxvf nrpe-2.13.tar.gz &>/dev/null
[root@localhost software]# cd nrpe-2.13
[root@localhost nrpe-2.13]# ./configure

[root@localhost etc]# echo "/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d" >> /etc/rc.local
[root@localhost etc]# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.13
[root@localhost etc]#
访问:http://192.168.10.99/nagios
但是，打开页面时，其他选项卡都是显示的502 Bad Gateway
[root@localhost ~]# chown nagios:nagcmd /usr/local/nagios/ -R
[root@localhost ~]# chown www:nagcmd /usr/local/nginx/ -R
[root@localhost ~]# cd /usr/local/nginx/
[root@localhost nginx]# ./start_perl_cgi.sh start
ERROR PID file /usr/local/nginx/logs/perl-fcgi.pid already exists
start perl-fcgi done
[root@localhost nginx]#
因为perl-fcgi进程意外中断，但是进程未退出变成了孤儿进程，所以就变成这样了
修改下脚本start_perl_cgi.sh
[root@localhost nginx]# ./start_perl_cgi.sh start
start perl-fcgi done
[root@localhost nginx]#
[root@localhost nginx]# /etc/init.d/nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios: done.
[root@localhost nginx]# /etc/init.d/nginx restart
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
Stopping nginx: [ OK ]
Starting nginx: [ OK ]
[root@localhost nginx]#
OK，在Nginx上安装Nagios成功
如果出现上面的问题，解决方法：
[root@localhost ~]# sed -i ‘/use_authentication/s/1/0/g‘ /usr/local/nagios/etc/cgi.cfg
[root@localhost ~]# /etc/init.d/nagios restart
Running configuration check...done.
Stopping nagios: done.
Starting nagios: done.
[root@localhost ~]# /etc/init.d/nginx restart
nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
Stopping nginx: [ OK ]
Starting nginx: [ OK ]
[root@localhost ~]#
访问http://192.168.10.99/nagios/
OK，Successful
