yum安裝nagios(centos 6.2)

發(fā)布時(shí)間：2020-06-17 20:39:15 來(lái)源：網(wǎng)絡(luò) 閱讀：2130 作者：zhhmj 欄目：移動(dòng)開(kāi)發(fā)

前提先自行安裝好Apache+php
測(cè)試環(huán)境
主監(jiān)控機(jī)：CentOS 6.2  172.16.1.8
被監(jiān)控機(jī)：CentOS 6.2  172.16.5.11
主監(jiān)控機(jī)設(shè)置:
1、安裝epel
# cat /etc/issue
CentOS release 6.2 (Final)
Kernel \r on an \m
# rpm -ivh rpm -ivh http://dl.iuscommunity.org/pub/ius/stable/Redhat/6/x86_64/epel-release-6-5.noarch.rpm                         這里應(yīng)該對(duì)應(yīng)你服務(wù)器的版本
2、安裝nagios、nagios-plugin與nrpe (nagios 3.3.1版本)
# yum install nagios nagios-plugins nagios-plugins-all nagios-plugins-nrpe nrpe
3、創(chuàng)建一個(gè)nagiosadmin 的用戶(hù)用于Nagios的WEB接口登錄，用戶(hù)認(rèn)證配置useradd nagiosadmin
# htpasswd -c /etc/nagios/passwd nagiosadmin
New password:
Re-type new password:
Adding password for user nagiosadmin
4、修改cgi.cfg文件，找到use_authentication=1 這行，把1改成0
#find -name cgi.cfg -print    查找
#vi /etc/nagios/cgi.cfg
5、啟動(dòng)apache與nagios
# /etc/init.d/httpd restart
# /etc/init.d/nagios start
6、登陸http://localhost/nagios/，輸入用戶(hù)密碼后查看是否正常運(yùn)行
注：別忘記了nagios后面那個(gè)/
被監(jiān)控機(jī)設(shè)置:
1、安裝需要軟件
# yum install nagios-plugins nagios-plugins-nrpe nrpe
2、配置nrpe
# vi /etc/nagios/nrpe.cfg 修改監(jiān)控機(jī)的地址或域名
allowed_hosts=127.0.0.1,192.168.1.8
3、修改/etc/hosts.allow增加監(jiān)控機(jī)ip
# echo ‘nrpe:192.168.1.8′ >> /etc/hosts.allow
4、檢查 NRPE 是否正常：
監(jiān)控機(jī)上：
# /usr/lib64/nagios/plugins/check_nrpe -H 192.168.5.11
NRPE v2.12
查看相應(yīng)的端口：netstat -an |grep 5666
防火墻開(kāi)啟5666 允許局域網(wǎng)IP或固定IP連接
5、啟動(dòng) NRPE 守護(hù)進(jìn)程：
# /usr/sbin/nrpe -c /etc/nagios/nrpe.cfg –d     或者
#/etc/init.d/nrpe start
6、關(guān)閉selinux：
#setenforce 0
在回到監(jiān)控機(jī)：
添加nrpe的定義
# vi commands.cfg
# ‘check_nrpe’ command definition
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
增加主機(jī)監(jiān)控配置項(xiàng)www.cfg

并把www.cfg添加到nagios主配置項(xiàng)
# echo “cfg_file=/etc/nagios/objects/www.cfg” >> /etc/nagios/nagios.cfg
其他機(jī)器如法炮制即可
