nagios监控windows和linux主机示意图:
1.首先要确定nagios监控软件在服务器端安装
2.在监控端要安装nrpe插件
[root@tong1 ~]# yum install xinetd openssl openssl-devel -y
[root@tong1 ~]# wget http://liquidtelecom.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz
[root@tong1 ~]# tar xvf nrpe-2.15.tar.gz
[root@tong1 ~]# cd /root/nrpe-2.15
[root@tong1 nrpe-2.15]# ./configure --prefix=/usr/local/nagios-plugins-2.0.3/
[root@tong1 nrpe-2.15]# make all
[root@tong1 nrpe-2.15]# make install-plugin
[root@tong1 nrpe-2.15]# ll /usr/local/nagios-4.0.8/libexec/check_nrpe
-rwxrwxr-x. 1 nagios nagios 76769 Apr 1 17:35 /usr/local/nagios-4.0.8/libexec/check_nrpe
[root@tong1 nrpe-2.15]#
3.在Linux被控端安装客户端软件(nagios-plugins和nrpe)
[root@tong2 ~]# yum install openssl openssl-devel xinetd -y
[root@tong2 ~]# groupadd -g 500 nagios
[root@tong2 ~]# useradd -r -s /sbin/nologin -u 500 -g nagios nagios
[root@tong2 ~]# wget http://nagios-plugins.org/download/nagios-plugins-2.0.3.tar.gz
[root@tong2 ~]# wget http://liquidtelecom.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz
[root@tong2 ~]# tar xvf nagios-plugins-2.0.3.tar.gz
[root@tong2 ~]# tar xvf nrpe-2.15.tar.gz
[root@tong2 ~]# cd nagios-plugins-2.0.3
[root@tong2 nagios-plugins-2.0.3]# ./configure --prefix=/usr/local/nagios-plugins-2.0.3 --with-nagios-user=nagios --with-nagios-group=nagios
[root@tong2 nagios-plugins-2.0.3]# make && make install
[root@tong2 nagios-plugins-2.0.3]# cd /usr/local/
[root@tong2 local]# chown -R nagios:nagios nagios-plugins-2.0.3/
[root@tong2 local]# cd /root/nrpe-2.15
[root@tong2 nrpe-2.15]# ./configure --prefix=/usr/local/nagios-plugins-2.0.3/
[root@tong2 nrpe-2.15]# make all
[root@tong2 nrpe-2.15]# make install-plugin
[root@tong2 nrpe-2.15]# make install-daemon
[root@tong2 nrpe-2.15]# make install-daemon-config
[root@tong2 nrpe-2.15]# make install-xinetd
[root@tong2 nrpe-2.15]# ll /usr/local/nagios-plugins-2.0.3/

[root@tong2 nrpe-2.15]# vim /etc/xinetd.d/nrpe
only_from = 127.0.0.1 192.168.1.247 --添加监控服务器端地址
[root@tong2 nrpe-2.15]# vim /usr/local/nagios-plugins-2.0.3/etc/nrpe.cfg
allowed_hosts=127.0.0.1,192.168.1.247 --添加监控服务器主机的IP地址
[root@tong2 nrpe-2.15]# vim /etc/services
nrpe 5666/tcp # nrpe --添加服务器监听端口
[root@tong2 nrpe-2.15]# /etc/init.d/xinetd restart
Stopping xinetd: [ OK ]
Starting xinetd: [ OK ]
[root@tong2 nrpe-2.15]# netstat -antup | grep 5666
tcp 0 0 :::5666 :::* LISTEN 32747/xinetd
[root@tong2 nrpe-2.15]# /usr/local/nagios-plugins-2.0.3/libexec/check_nrpe -H localhost
NRPE v2.15
[root@tong2 nrpe-2.15]#
3.在监控端测试连接被控端,添加被控端主机
[root@tong1 nrpe-2.15]# /usr/local/nagios-4.0.8/libexec/check_nrpe -H 192.168.1.248
NRPE v2.15
[root@tong1 etc]# cd /usr/local/nagios-4.0.8/etc/objects/
[root@tong1 objects]# cp -a templates.cfg tong2.cfg
[root@tong1 objects]# vim tong2.cfg
