Centos/rhel 5 Platform Installation fan Nagios

First, fan is a CentOS-based mini-version system that can download ISO image installation directly. It can also be installed on the Redhat platform, and FAN 2.1 is typically installed on a 32-bit system on the Redhat 5.x platform.

Second, Configure the network and DNS

1.network

[Email protected] desktop]# Cat/etc/sysconfig/network-scripts/ifcfg-eth3

2.dns

[Email protected] desktop]# cat/etc/resolv.conf

Search Localdomain

NameServer 210.21.4.130

NameServer 221.5.88.88

Second, installed on the 32-bit system is very simple

1. Installing Epel-release

[Email protected] desktop]# RPM-UVH http://dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm

2. Install Graphviz repo:

[email protected] desktop]# Yum localinstall--nogpgcheck fan-repo-2.4-fan.1.noarch.rpm

4.64-bit system can not install this, need fan_nagios_x86_64.repo.tar.gz package (this package is I created a new source), the package is extracted directly into the/etc/yum.repos.d/folder can be

Third, install stable version 2.4

FAN Poller

[email protected] desktop]# Yum install Fan-poller

FAN Central

Iv. plotting historical curves with PnP

1. PnP is a tool based on PHP and Perl that uses RRDtool to chart data from Nagios, so you must install PHP, Perl, and RRDtool before you install PNP.

2. Install the required plugins

Yum-y Install gcc-c++

Yum-y Install Libxml2-devel

Yum-y Install pango*

3. Installing Cgilib

Tar zxvf cgilib-0.5.tar.gz

CD cgilib-0.5

CP Cgi.h/usr/include

4. Installing RRDtool

Tar zxvf rrdtool-1.4.5.tar.gz

CD RRDtool

./configure

Make all

Make install

5. Edit the file to the last face

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>

This is the end of the installation, the following is the error that occurred during my installation, and the workaround
