How to install Centos 5.2, PHP 5.2x, Mysql 5.1x and Magento 1.2.x Assuming that this is a server behind a firewall

Install Centos 5.2 (64bit) with correct IP settings and no packages selected except “base” restart and login

Update the system and download kernel headers in case they are needed for future software

yum update
yum install kernel*
reboot

Set the hosts file and disable ip6

nano /etc/hosts
Add IP and a hostname
nano /etc/modprobe.conf
Add 'alias ipv6 off'
Add 'net-pf-10 off'
Reboot

Disable un-needed services (look them up if you are interested)

chkconfig NetworkManager off
chkconfig NetworkManagerDispatcher off
chkconfig anacron off
chkconfig atd off
chkconfig bluetooth off
chkconfig cpuspeed off
chkconfig cups off
chkconfig gpm off

Install the remi repositories for updated versions of PHP and MySQL not offered by Centos

wget http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
wget http://rpms.famillecollet.com/el5.i386/remi-release-5-7.el5.remi.noarch.rpm
rpm -Uvh remi-release-5*.rpm epel-release-5*.rpm

yum --enablerepo=remi install php-mcrypt php-xml php-xml php-devel php-imap php-soap php-mbstring php-mysql
yum --enablerepo=remi install php-mhash php-simplexml php-dom php-gd

(php-mhash extension no longer required as of php5.3(which is what you’ll get following these commands)-replaced by HASH Message Digest Framework in php core)

yum --enablerepo=remi install mysql mysql-server
yum --enablerepo=remi install php-mysql php-pdo
