Use the following command to install Apache (httpd):

yum install httpd

Again, using yum to install PHP:

yum install php php-cli php-mysql

Note, there may be other PHP libraries you wish to install (search by yum search php*)

yum again:

yum install mysql-server mysql-common

Both will be installed as a service, so to start/restart/etc either, all you need do is:

service <httpd or mysql> <start, restart, stop>

A quick method:

service httpd start; service mysql start

Use this command to install Apache:

apt-get install apache2

Make sure the Apache log directory is owned by www-data:

chown www-data:www-data /var/log/apache2

Create an empty config file:

touch /etc/apache2/httpd.conf

Run this command to install the PHP packages needed to work with Apache:

apt-get install libapache2-mod-php5 php5-cli php5-common php5-cgi

Apache should automatically bind itself to run PHP when it encounters .php files.

This is the command to install the MySQL server, client and PHP’s MySQL libraries:

apt-get install mysql-client mysql-common mysql-server php5-mysql

Go to your document root(/var/www) and create a PHP file called ‘info.php’ and put this code inside it:

<?php
phpinfo();

First, start the MySQL database server:

/etc/init.d/mysql start

Then, start the Apache Web Server:

/etc/init.d/apache2 start

Then go to

http://yourhostname_or_ip/info.php

If you see a page looking like this, Apache and PHP are working.
