Installing httpd and PHP on Centos 5
Introduction
Apache is the software that allows websites to be displayed through a web browser such as Microsoft Internet explorer, Mozilla Firefox, Opera and Google Chrome etc. Apache on its own can only display HTML (Hyper Text Mark-up Language) Files.
PHP allows you to run server side code, Web Applications, Dynamic Websites can be run or created on the server. Many websites use PHP such as Facebook, Wikipedia, Yahoo, Digg, Joomla, WordPress, Drupal etc.
PHP is required to run many Web Applications, such as
Blogs:
- Wordpress
Galleries:
- Gallery
- Camera Life
Forums:
- phpBB
- Invision Power Board
- PHP Forum Script
Content Management Systems:
- PHPNuke
- Drupal
- PHP-Fusion
Tools:
- Webmin
- Drupal
- Squirrel Mail
PHP doesn’t just run with Apache, you can use PHP to run code at the command line too.
Installation
[root@vps ~]# yum install httpd php php-mysql
N.B Dont worry if what comes up on your screen is different to this. Software Versions and dependencies change.

Dont worry about the extra packages showing up in the list, these extras are required to make PHP and Apache work.
Press Y and then Enter.

Now that Yum has completed installing Apache and PHP, we just need to create a system start-up link, so that Apache starts when the server does. PHP doesn't need this doing, as it utilised when Apache needs it.
[root@vps ~]# chkconfig httpd on
Finally all we need to do is to start Apache
[root@vps ~]# service httpd start Starting httpd: [ OK ]
You can check to make sure its working by going to your server IP in your web browser.
You should see the Apache test page.
Basic Configuration Httpd
The apache config file is located /etc/httpd/conf/httpd.conf
At this stage there isn't really anything that needs changing in the config file, except maybe the server email address.
Editing the config file with vi (vi is a text editor) for more information about text editors click here
[root@vps ~]# vi /etc/httpd/conf/httpd.conf
if you wish to add your email address, find
# # ServerAdmin: Your address, where problems with the server should be # e-mailed. This address appears on some server-generated pages, such # as error documents. e.g. admin@your-domain.com # ServerAdmin root@localhost
Update root@localhost and then save the file.
If you make any changes to the config file, you will need to restart httpd.
[root@vps ~]# service httpd restart Stopping httpd: [ OK ] Starting httpd: [ OK ]
Basic Configuration PHP
The PHP config file can be found /etc/php.ini. At this time there isn't anything that needs changing as part of the basic setup. However if you do need to change any settings with in PHP then its the same process as described in Basic Configuration Httpd but with the path to php.ini instead.
