If you guys are using centos 5.6
then follow the steps below:

su root:

yum install httpd php

yum install gcc-3.4.6-8 compat-gcc* libgcc* compat-libgcc* compat-gcc-32* gcc-c++* glibc* glibc-common*

yum install gd gd-devel

/usr/sbin/useradd -m nagios

passwd nagios

/usr/sbin/groupadd nagcmd

/usr/sbin/usermod -a -G nagcmd nagios

/usr/sbin/usermod -a -G nagcmd apache

Download nagios and nagios-plugins as follows:

wget http://nchc.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.3.1/nagios-3.3.1.tar.gz

wget http://space.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz
eg: if you are downloading as a user called, ishara: then enter the command:

cd /home/ishara/Downloads

Extract and Install nagios as follows:

tar xvf nagios-3.3.1.tar.gz

cd nagios*
./configure –with-command-group=nagcmd
make all

make install

make install-init

make install-config

make install-commandmode

make install-webconf

Now provide a password for the username called nagiosadmin: run the following command:

htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

/sbin/service httpd restart

Now let’s install the nagios-plugins as follows: Enter

tar xvf nagios-plugins-1.4.15.tar.gz

cd nagios-plugins*

./configure –with-nagios-user=nagios –with-nagios-group=nagios

make

make install

Add nagios service to the startup as follows: Enter:

chkconfig —add nagios

chkconfig nagios on

To disable SELinux to permissive mode: Enter:

/usr/sbin/setenforce 0

chcon -R -t httpd_sys_content_t /usr/local/nagios/sbin/

chcon -R -t httpd_sys_content_t /usr/local/nagios/share/

All work done in the terminal now in and now in firefox or any web-browser, type

http://localhost/nagios/

Enter username : nagiosadmin and the relevant password you entered above:

DONE!!! ENJOY NAGIOS
