Installation

Adminer is available in source package, Debian package and Arch Linux package.

On Debian / Ubuntu based Linux

$ sudo apt-get install adminer
$ sudo /etc/init.d/apache2 restart

The latest version of Adminer at the time this article is written is version 4.0.2. But on Debian package, it still at the 3.3.3 version. So if you are using apt-get tool, you will get 3.3.3 version.

To upgrade it into the latest version, we need to use it’s source code file. Installation using source file can be applied in most Linux distribution.

Before we continue, please notice that we only show to you that how easy to setup Adminer using Apache as a web server. But since managing database should be installed in a secure way - such as using .htaccess file -, this installation may not the best installation from security point of view.

Here are the steps :

1. Download the latest version of Adminer

$ wget http://downloads.sourceforge.net/adminer/adminer-4.0.2.php

2. Create a directory named adminer (or any name you want) in Apache DocumentRoot directory
Let say that the Apache DocumentRoot directory is /var/www

$ mkdir /var/www/adminer

3. Copy the file - adminer-4.0.2.php - into the adminer directory

$ cp adminer-4.0.2.php /var/www/adminer

Databases

Adminer provide a clean login page. We only need to fill what kind database we are using, the server address, username, password and database (optional).

After those fields are filled correctly, then you will see a database administration page.
