CentOS/RHEL 5平臺如何安裝FAN nagios

這篇文章主要為大家展示了“CentOS/RHEL 5平臺如何安裝FAN nagios”，內容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領大家一起研究并學習一下“CentOS/RHEL 5平臺如何安裝FAN nagios”這篇文章吧。

一、FAN是一個基于centos的迷你版系統，可以直接下載iso鏡像安裝。它也可以安裝在redhat平臺上，FAN 2.1一般都是安裝在redhat 5.x平臺的32位系統上。

二、配置網絡和dns

1.network

[root@oracle64 Desktop]# cat /etc/sysconfig/network-scripts/ifcfg-eth4 

2.dns

[root@oracle64 Desktop]# cat /etc/resolv.conf 

search localdomain

nameserver 210.21.4.130

nameserver 221.5.88.88

二、安裝在32位的系統上很簡單

1.安裝 epel-release

[root@oracle64 Desktop]# rpm -Uvh http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

2.安裝 Graphviz repo :

[root@oracle64 Desktop]# cd /etc/yum.repos.d/

[root@oracle64 Desktop]# wget http://www.graphviz.org/graphviz-rhel.repo

3.安裝 FAN repo :

[root@oracle64 Desktop]# wget http://www.fullyautomatednagios.org/FAN/repository/2.4/i386/fan-repo-2.4-fan.1.noarch.rpm

[root@oracle64 Desktop]# yum localinstall --nogpgcheck fan-repo-2.4-fan.1.noarch.rpm

4.64位系統不能這樣安裝，需要fan_nagios_x86_64.repo.tar.gz包(這個包是我自己新建了一個源),把該包直接解壓縮到/etc/yum.repos.d/文件夾即可

三、安裝 stable version 2.4

FAN standalone

[root@oracle64 Desktop]# yum install fan-standalone

FAN poller

[root@oracle64 Desktop]# yum install fan-poller

FAN central

[root@oracle64 Desktop]# yum install fan-central

FAN database

[root@oracle64 Desktop]# yum install fan-database

四、用PNP繪制歷史曲線

1. Pnp是一個基于php和perl，用rrdtool將nagios采集的數據繪制圖表的工具，所以安裝pnp之前必須先安裝php、perl和rrdtool。

2.安裝需要的插件

yum -y install gcc-c++ 

yum -y install libxml2-devel

yum -y install pango*

3.安裝cgilib

tar zxvf cgilib-0.5.tar.gz

cd cgilib-0.5

cp cgi.h /usr/include

4.安裝rrdtool

tar zxvf rrdtool-1.4.5.tar.gz

cd rrdtool

./configure

make all

make install

5.編輯文件添加到最后面

vi /etc/httpd/conf/http.conf

Alias /pnp "/usr/local/nagios/share/pnp"

<Directory "/usr/local/nagios/share/pnp">

     Options None

     AllowOverride None

     Order allow,deny

     Allow from all

     Authname "nagios access"

     Authuserfile /etc/nagios/htpasswd.users

     Require valid-user

     Authtype basic

</Directory>

6.啟動apache和nagios就ok了，瀏覽器訪問http://ip/nagios，nagios默認用戶名密碼都是nagiosadmin

五、報錯

1.網卡流量報錯：Return code of 127 is out of bounds - plugin may be missing

/usr/lib/nagios/plugins/該文件夾下面缺少流量檢查腳本，然后賦權

ll /usr/lib/nagios/plugins/check_traffic.sh

cd /usr/lib/nagios/plugins

chmod 777 -R plugins

chown -R nagios.nagios  plugins

2.vi /etc/httpd/conf/httpd.conf 

找到#ServerName www.example.com:80   把#去掉，再重啟apache即可

Starting httpd: httpd: Could not reliably determine the server's fully qualified domain name, using 172.16.195.101 for ServerName

3.nagios告警全部關掉模塊報錯

Error: Could not stat() command file '/var/log/nagios/rw/nagios.cmd'!

拷貝一個nagios.cmd文件到下面目錄，然后賦權解決

chmod -R 777 /var/log/nagios/rw/

4.CHECK_NRPE: Error - Could not complete SSL handshake.

 vi /usr/local/nagios/etc/nrpe.cfg

添加nagios IP地址210.31.118.245 

然后重啟nrpe

5.這些是只有210.31.118.245 機器ping不通，那就是防火墻屏蔽了，添加

PING CRITICAL - Packet loss = 100% 

/sbin/iptables -A INPUT -p icmp -s 210.31.118.245  -j ACCEPT

6.這些都是5666端口telnet不通的，也是防火墻屏蔽了

CHECK_NRPE: Socket timeout after 10 seconds.

CHECK_NRPE: Socket timeout after 10 seconds.

/sbin/iptables -A INPUT -p tcp --dport 5666 -i eth2 -j ACCEPT
