Nagios被監控端的安裝
作者：lz1130
Nagios被監控端安裝：Nagios的功能是監控服務和主機，而且提供了友好的WEB界面查看當前的網絡狀態、通知和故障歷史、日志文件…但是他自身并不包括這部分功能的代碼，所有的監控、檢測功能都是有插件來完成的。本文講述的是Nagios被監控端的安裝
Nagios被監控端安裝
沒安裝xinetd的要安裝
- yum -y install xinetd
- yum -y install xinetd
安裝Nagios插件
- ./configure --with-nagios-user=nagios --with-nagios-group=nagios
- make
- make install
- ./configure --with-nagios-user=nagios --with-nagios-group=nagios
- make
- make install
安裝nrpe
- ./configure
- make all
- make install-daemon
- make install-daemon-config
- make install-xinetd
- ./configure
- make all
- make install-daemon
- make install-daemon-config
- make install-xinetd
配置nrpe啟動
- vi /etc/xinetd.d/nrpe
- service nrpe
- {
- flags = REUSE
- socket_type = stream
- port = 5666
- wait = no
- user = nagios
- group = nagios
- server = /usr/local/nagios/bin/nrpe
- server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
- log_on_failure += USERID
- disable = no
- only_from = 127.0.0.1 10.3.37.110
- #only_from: allow monit server ip. “ ”ge kai duo ge ip
- }
- vi /etc/xinetd.d/nrpe
- service nrpe
- {
- flags = REUSE
- socket_type = stream
- port = 5666
- wait = no
- user = nagios
- group = nagios
- server = /usr/local/nagios/bin/nrpe
- server_args = -c /usr/local/nagios/etc/nrpe.cfg --inetd
- log_on_failure += USERID
- disable = no
- only_from = 127.0.0.1 10.3.37.110
- #only_from: allow monit server ip. “ ”ge kai duo ge ip
- }
- vi /etc/services
- vi /etc/services
加入以下：
- nrpe 5666/tcp # nrpe
- nrpe 5666/tcp # nrpe
重啟 xinetd 服務
- /etc/init.d/xinetd restart
- /etc/init.d/xinetd restart
檢查nrpe是否正常工作
在監控端執行以下命令，返回版本則成功。
/usr/local/nagios/libexec/check_nrpe -H 被監控端ip
NRPE v2.8.1
/usr/local/nagios/libexec/check_nrpe -H 被監控端ip
NRPE v2.8.1
配置監控命令
- vi /usr/local/nagios/etc/nrpe.cfg
- vi /usr/local/nagios/etc/nrpe.cfg

檢查監控命令是否生效
在監控端執行以下命令，返回結果則成功。
- /usr/local/nagios/libexec/check_nrpe -H被監控端ip -c check_load
- OK - load average: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0; load5=0.000;10.000;25.000;0; load15=0.000;5.000;20.000;0;
