Install Adminer on Ubuntu 18.04 bionic

In the next few steps, I'll show you how I installed adminer for Ubuntu 18.04.1 LTS .

1. After installation with apt package manager change into the adminer directory.

   cd /usr/share/adminer
   

   There you will find a file called compile.php.

2. Run the following command and the adminer-X.X.X.php (X.X.X for your version) file will be created.

   sudo php compile.php
   

3. Create the apache adminer configuration file.

   sudo echo "Alias /adminer.php /usr/share/adminer/adminer-X.X.X.php" | sudo tee /etc/apache2/conf-available/adminer.conf
   

4. Now you'll need to activate the configuration.

   cd /etc/apache2/conf-available/
   sudo a2enconf adminer.conf
   

5. Reload your apache webserver.

   sudo systemctl reload apache2.
   

6. Test in your browser of choice (localhost/adminer.php)
