监控软件nagios之添加Linux主机

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/
total 20
drwxrwxr-x. 2 nagios nagios 4096 Apr  1 17:18 bin
drwxrwxr-x. 2 nagios nagios 4096 Apr  1 17:18 etc
drwxr-xr-x. 2 nagios nagios 4096 Apr  1 17:10 include
drwxrwxr-x. 2 nagios nagios 4096 Apr  1 17:18 libexec
drwxr-xr-x. 3 nagios nagios 4096 Apr  1 17:10 share

[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
