Installing Nagios made easy

Installing nagios by hand is good but not recommended.Instead use a small script to do the job for you...because being an system admin you have lot of thing to take care...so the time will be crucial factor. But having said I have had no intention to make it a point that you automate whatever you want. Sometime the automation has the adverse effect on system.You do automation when it must require and need.

I do not issue any guarantee that this will work for you.

So the script for installing Nagios and it's plugins from source is below...u can also enhance it if you want...

#!/bin/bash
# This script will install Nagios from source along with the plugins.
dir=/usr/local/nagios
wget -c http://osdn.dl.sourceforge.net/sourceforge/nagios/nagios-3.0.6.tar.gz
wget -c http://osdn.dl.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.11.tar.gz
mkdir -p $dir
grep -i “red hat” /etc/issue>/dev/null2>&1
if [ `echo $? ` = 0 ];then
useradd nagios
else
groupadd nagios
useradd -G nagios nagios
fi
tar xzf nagios-plugins-1.4.11.tar.gz
cd nagios-plugins-1.4.11
./configure –prefix=/usr/local/nagios –enable-redhat-pthread-workaround
make
make install
cd ..
tar xzf nagios-3.0.6.tar.gz
cd nagios-3.0.6
./configure –prefix=/usr/local/nagios
make install
make install-init
make install-config
make install-commandmode
make install-webconf
# make sure xinetd is installed.
echo ” nrpe 5666/tcp #nrpe” >> /etc/services
chown -R nagios.nagios /usr/local/nagios
service xinetd [...]

But one word caution for heaven's sake please investigate manually or put some mechanism within the script to check that everything done as required.

Hope this will help.
