Installing PHP MyAdmin on Ubuntu is very easy, in this tutorial we will install PHP MyAdmin via command line, it is assumed that you have already installed Apache, MySQL and PHP, if not follow instruction in this post to install and configure Apache, MySQL and PHP.

Installing PHP MyAdmin

Open up your terminal application, Terminal app is located

In Ubuntu Unity: Click the dash icon in the upper left corner of desktop, and type terminal, click terminal icon under applications.

If not using Unity: Goto Applications > Accessories > Terminal

Or simply press Alt + Ctrl + T at the same time

Execute following command to install PHP MyAdmin

sudo apt-get install phpmyadmin

In the middle of installation you will be prompted to select a web-server in list of available web-servers, select Apache 2 and hit enter, PHP MyAdmin is installed on Ubuntu now but you will not be able to access it via “http://localhost/phpmyadmin/”, default installation directory for PHP MyAdmin is “/usr/share/phpmyadmin/“, we need to create Symbolic Link (symlink) to the installation directory from document root. Execute following command to create one.

sudo ln -s /usr/share/phpmyadmin/ /var/www/phpmyadmin

After you have done this you will be able to access PHP MyAdmin via “http://localhost/phpmyadmin/”, use your MySQL username and password to login to PHP Myadmin.

• Installing LAMP (Linux, Apache, MySQL, PHP), which is not more than just extracting an archive file to a directory, and you are done everything is pre-configured you just need to run lamp start command. (Will be covered in other post)
• Installing Apache, MySQL, PHP one by one using terminal application, this method help us understand some basic configurations.

As we are going to install all these applications using terminal, open up your terminal application, Terminal app is located

In Ubuntu Unity: Click the dash icon in the upper left corner of desktop, and type terminal, click terminal icon under applications.

If not using Unity: Applications > Accessories > Terminal

Or simply press Alt + Ctrl + T at the same time

 Installing Apache

Now so that terminal app is open enter following command to install Apache webserver

sudo apt-get install apache2

After installation is complete goahead and type “http://localhost/” in your web-browser and hit enter. If you are able to see “It Works”, you installed Apache correctly.

Note: if you see an error like “Could not reliably determine the server’s fully qualified domain name, using 127.0.0.1 for ServerName“, at the end of installation, fix this issue using following command

gksu gedit /etc/apache2/conf.d/fqdn

This command will open Gedit, enter following line in the file, save it and close the file.

“ServerName localhost”

After you have done with above fix, type following command to restart Apache, and you will no more see the error

sudo service apache2 restart

Installing PHP

To install and configure PHP with Apache, execute following command

sudo apt-get install php5 libapache2-mod-php5

This command does two things, install PHP5 and configure it with Apache, after terminal is finished with the installation you have to restart Apache in order to complete the installation and finish PHP configuration with apache. Use one the following command to restart Apache.

sudo /etc/init.d/apache2 restart

OR

sudo service apache2 restart

To test your configuration, use following command to open Gedit, which will save file index.php in /var/www/ which is default document root for Apache

sudo gedit /var/www/index.php

Put following code in the file and open “http://localhost/” in web-browser, it will display all your PHP settings

<?php phpInfo(); ?>

Installing MySQL

Inside terminal type following command to install MySQL, this command installs MySQL and configure it with Apache and PHP

sudo apt-get install mysql-server libapache2-mod-auth-mysql php5-mysql

Once the installation is complete, you will be prompted to enter password for the default user “root” of MySQL. Provide a password and confirm it to complete the installation or you can leave it blank by clicking enter.
