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
  chkconfig hidd off
  chkconfig ip6tables off
  chkconfig iptables off
  chkconfig irda off
  chkconfig mdmonitor off
  chkconfig mdmpd off

Install Apache

  yum install httpd
  chkconfig httpd on
  service httpd start

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

Install php and required php extensions for Magento

  yum --enablerepo=remi install php-common
  yum --enablerepo=remi install php
  yum install gd gd-devel
  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-pear php-pecl-imagick php-magickwand

(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)

Install/Configure newest Mysql and Php extensions and enable in php.ini

  yum --enablerepo=remi install mysql mysql-server
  yum --enablerepo=remi install php-mysql php-pdo
  nano /etc/php.ini
      Add 'extension=pdo.so'
      Add 'extension=pdo_mysql.so'
  mysql_install_db
  mysqladmin -u root password SOMEPASSWORD

(I had an error at mysql_install_db-the errmsg.sys file in mysql/share/english did not match the required file-it had a different number of errors. I solved this by downloading the most recent non-rpm linux binary to my local machine and uploading that errmsg.sys file to mysql/share/english)
