nagios监控windows和linux主机示意图:http://s3.运维网.com/wyfs02/M02/75/02/wKiom1YweoTDy8pZAAH2FnORSwA486.jpg
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
# yum install xinetd openssl openssl-devel -y
# wget http://liquidtelecom.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz
# tar xvf nrpe-2.15.tar.gz
# cd /root/nrpe-2.15
# ./configure--prefix=/usr/local/nagios-plugins-2.0.3/
# make all
# make install-plugin
# ll /usr/local/nagios-4.0.8/libexec/check_nrpe
-rwxrwxr-x. 1 nagios nagios 76769 Apr1 17:35 /usr/local/nagios-4.0.8/libexec/check_nrpe
#
3.在Linux被控端安装客户端软件(nagios-plugins和nrpe)
# yum install openssl openssl-devel xinetd -y
# groupadd-g 500 nagios
# useradd-r -s /sbin/nologin -u 500 -g nagios nagios
# wget http://nagios-plugins.org/download/nagios-plugins-2.0.3.tar.gz
# wget http://liquidtelecom.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz
# tar xvf nagios-plugins-2.0.3.tar.gz
# tar xvf nrpe-2.15.tar.gz
# cd nagios-plugins-2.0.3
# ./configure --prefix=/usr/local/nagios-plugins-2.0.3 --with-nagios-user=nagios --with-nagios-group=nagios
# make && make install
# cd /usr/local/
# chown-R nagios:nagios nagios-plugins-2.0.3/
# cd /root/nrpe-2.15
# ./configure--prefix=/usr/local/nagios-plugins-2.0.3/
# make all
# make install-plugin
# make install-daemon
# make install-daemon-config
# make install-xinetd
# ll /usr/local/nagios-plugins-2.0.3/

only_from = 127.0.0.1 192.168.1.247 --添加监控服务器端地址
# 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
# vim /etc/services
nrpe 5666/tcp # nrpe --添加服务器监听端口
# /etc/init.d/xinetd restart
Stopping xinetd:
Starting xinetd:
# netstat -antup | grep 5666

# /usr/local/nagios-plugins-2.0.3/libexec/check_nrpe -H localhost
NRPE v2.15
#
3.在监控端测试连接被控端,添加被控端主机
# /usr/local/nagios-4.0.8/libexec/check_nrpe -H 192.168.1.248
NRPE v2.15
# cd /usr/local/nagios-4.0.8/etc/objects/
# cp -a templates.cfgtong2.cfg
# vim tong2.cfg
