Installing Apache2 With PHP5 And MySQL Support On CentOS 5.3 (LAMP) - Page 2

5 Testing PHP5 / Getting Details About Your PHP5 Installation

The document root of the default web site is /var/www/html. We will now create a small PHP file (info.php) in that directory and call it in a browser. The file will display lots of useful details about our PHP installation, such as the installed PHP version.

vi /var/www/html/info.php


Now we call that file in a browser (e.g.

As you see, PHP5 is working, and it's working through the Apache 2.0 Handler, as shown in the Server API line. If you scroll further down, you will see all modules that are already enabled in PHP5. MySQL is not listed there which means we don't have MySQL support in PHP5 yet.


6 Getting MySQL Support In PHP5

To get MySQL support in PHP, we can install the php-mysql package. It's a good idea to install some other PHP5 modules as well as you might need them for your applications. You can search for available PHP5 modules like this:

yum search php

Pick the ones you need and install them like this:

yum install php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc

Now restart Apache2:

/etc/init.d/httpd restart

Now reload in your browser and scroll down to the modules section again. You should now find lots of new modules there, including the MySQL module:


7 phpMyAdmin

phpMyAdmin is a web interface through which you can manage your MySQL databases.

First we enable the RPMforge repository on our CentOS system as phpMyAdmin is not available in the official CentOS 5.3 repositories:

On x86_64 systems:

rpm -Uvh rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

On i386 systems:

rpm -Uvh rpmforge-release-0.3.6-1.el5.rf.i386.rpm

phpMyAdmin can now be installed as follows:

yum install phpmyadmin

Now we configure phpMyAdmin. We change the Apache configuration so that phpMyAdmin allows connections not just from localhost (by commenting out the <Directory "/usr/share/phpmyadmin"> stanza):

vi /etc/httpd/conf.d/phpmyadmin.conf

#  Web application to manage MySQL
#<Directory "/usr/share/phpmyadmin">
#  Order Deny,Allow
#  Deny from all
#  Allow from
Alias /phpmyadmin /usr/share/phpmyadmin
Alias /phpMyAdmin /usr/share/phpmyadmin
Alias /mysqladmin /usr/share/phpmyadmin

Next we change the authentication in phpMyAdmin from cookie to http:

vi /usr/share/phpmyadmin/

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

Restart Apache:

/etc/init.d/httpd restart

Afterwards, you can access phpMyAdmin under

Instead of using the command "mysqladmin" to set the root password and access mask, you are better off using the command "/usr/bin/mysql_secure_installation"; it will run you through several steps to make your mysql installation secure (root password, root access mask, test users, test databases).

Great guide and works perfectly, thank you.

Useful for setting up so many things, in my case it was Joomla.

Thanks a lot, its working well. :)

From: Andriy Zhdanov at: 2012-04-22 23:30:32

First of all, thanks, it helped a lot.

And, it's missing:

yum install php-mysql

And to set host password the new password is also needed:

mysqladmin -h -u root -pyourrootpassword password yogamamadvd

From: Kenshin at: 2009-10-23 03:35:52

why does it ask for a username/password after going to phpmyadmin?

From: byoungtgs at: 2011-01-17 23:06:00

I ran into an issue using RPMforge on RedHat 5.5, it is looking for the dep "php-mcrypt", but that package isn't supplied by rpmforge or RedHat.

I used "epel" instead of "rpmforge".

rpm -Uvh
then ran a "yum install phpmyadmin" and it worked perfectly

From: John Hopkins at: 2011-10-03 21:38:24

Thanks for the heads up. Worked great for me. 

From: elmo at: 2012-05-30 13:22:35

Great!!!Thumbs up :)

You should consider adding simple instructions or links to configuring iptables to allow http access.  Here's my "quick and dirty" version for those who need help:

You'll need to add one line to the iptables file, and restart the services:

# cd /etc/sysconfig
# vi iptables

##### Insert the following line, to allow any user to access port 80, the common port for http.

-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

# /sbin/service iptables restart

From: DeJoe at: 2012-07-17 04:54:45

if firewall blocked use  # system-config-firewall-tui , enable www(http). and yes http is apache in redhat family ..
