How to Install phpmyadmin on Ubuntu 10.04 LTS Server

phpmyadmin is a web interface to your MySQL databases. It makes managing, creating and configuring your MySQL database a breeze. It is a very common tool and is often installed by default by many web host. In this article we will cover on how to install PHPMYSQL on Ubuntu Server 10.04 (LTS).

Create phpmyadmin db password or you can leave it blank to have one created for you. I have always created one myself.

We will need to know the IP address of the machine you just installed phpmyadmin on. Once we know this we can access the tools from a web browser on a computer on your network. It is a good idea to set a static IP address on your server so it will not change. If you need some help on how to do this on an Ubuntu server take a look at the following article:

Type the following to find your IP address






You can see one device has an IP address of We can ignore this address because this is a loopback address. I can see that my IP address for device eth0 is



ifconfig find ip




So now that we know the IP address of the machine with phpmyadmin installed. Let’s navigate to the phpmyadmin login page.




url - phpmyadmin




phpmyadmin login page




User name will be root

Password will be the root password when you installed MySQL.

How to install LAMP on Ubuntu (Linux, Apache, MySQL and PHP) in one command

Lamp stands for Linux, Apache, MySQL and PHP. These tools are very common for running many websites such as WordPress, Drupal, Joomla, Collabtive…etc. In Ubuntu we can easily install Apache2, MySQL and PHP with one simple command. In later articles we will later setup some of these open source web applications and use the complete LAMP server.  If you are interested in following some of theses tutorials please subscribe to the RSS feed.

Since by default the Ubuntu server does not have a GUI we will install LAMP with the command line. If you do have a GUI installed, you can open a terminal and issue the following commands. This goes for your desktop as well.  Lets get started.


sudo apt-get install lamp-server^


sudo apt-get install lamp-server^
