First let's install the pre-req's


 


INSTALL APACHE



yum install httpd -y


service httpd start


chkconfig httpd on

NOTE: If you get an error like



[root@srvr01 ~]# service httpd start


Starting httpd: httpd: apr_sockaddr_info_get() failed for srvr01.thezah.com


httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName


 



The fix is to add your IPAddress and hostname to /etc/hosts


 


Allow port 80 through the builtin firewall (iptables)



vi /etc/sysconfig/iptables

Add the following line




-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

Restart the builtin firewall



service iptables restart

Test that Apache is working by opening a browser and navigating to http://localhost/ or http://server-ip-address/


 


INSTALL MySQL



yum install mysql mysql-server -y

Start MySQL Service



service mysqld start

Turn mysql service each time your server reboots



chkconfig mysqld on

Set the mysql root password



mysql_secure_installation

INSTALL PHP



yum install php -y

Create a test php file



vi /var/www/html/testphp.php

Add the following




<?php
phpinfo();
?>

Restart Apache



service httpd restart

See if your PHP is working by loading that testphp.php file you created



http://server-ip-address/testphp.php

Install mysql plugin for php



yum install php-mysql -y

INSTALL phpMyAdmin


PreReq is to add distribution that holds the phpmyadmin package to yum repository



wget http://epel.mirror.net.in/epel/6/i386/epel-release-6-8.noarch.rpm
rpm -Uvh epel-release-6-8.noarch.rpm
yum repolist

yum install phpmyadmin -y


cp /usr/share/phpMyAdmin/config.sample.inc.php /usr/share/phpMyAdmin/config.inc.php


vi /usr/share/phpMyAdmin/config.inc.php

change cookie to http



/* Authentication type */ 
$cfg['Servers'][$i]['auth_type'] = 'http';
