Installing Apache2 With PHP5 And MySQL Support On CentOS 5.6 (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

<?php
phpinfo();
?>

Now we call that file in a browser (e.g. http://192.168.0.100/info.php):

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 http://192.168.0.100/info.php 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 5.6 repositories:

On x86_64 systems:

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm
rpm -Uhv rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

On i386 systems:

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm
rpm -Uhv rpmforge-release-0.5.2-2.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 127.0.0.1
#</Directory>

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/config.inc.php

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

Restart Apache:

/etc/init.d/httpd restart

Afterwards, you can access phpMyAdmin under http://192.168.0.100/phpmyadmin/:

The "mysql_secure_installation" step failed with the error:

-------------------------------------------------------------------

Remove anonymous users? [Y/n] Y

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

... Failed!

-------------------------------------------------------------------

To solve this problem change line (~50) in the script: /usr/bin/mysql_secure_installation

from

echo "password=$rootpass"

to

echo "password='$rootpass'"

After this change, no problems!

The original reference for this bug fix is at: http://bugs.mysql.com/bug.php?id=48031

I hope this saves others some time.

After the apache2 steps, open the "www" ports in the firewall using:

 system-config-securitylevel

Why stick to PHP 5.1.6 ??

Perhaps time for SL 6? It has PHP 5.3
