sudo apt-get update
sudo apt-get install apache2 - Webserver
sudo apt-get install mysql-server mysql-client libmysqlclient-dev - MySql
sudo apt-get install -y phpmyadmin - PhpMyAdmin

Naturally, because phpMyAdmin is such a common application installed on many web servers, it is a popular target for unauthorized access attempts. We can easily secure our phpMyAdmin installation by using Apache’s built-in .htaccess authentication.

Step 1: Edit phpMyAdmin’s Apache Config
We want to edit the phpMyAdmin Apache config that was created earlier:

sudo vi /etc/apache2/conf-available/phpmyadmin.conf

Add AllowOverride “ALL” directive below the DirectoryIndex:

        Options FollowSymLinks
        DirectoryIndex index.php
        AllowOverride ALL

Step 2: Restart Apache to Accept Config Changes
Restart Apache so our changes take affect:
sudo service apache2 restart
Step 3: Create an .htaccess File
Now that we’ve enabled overrides for our phpMyAdmin application from Apache, we need to actually create an override with an .htaccess file.

sudo vi /usr/share/phpmyadmin/.htaccess
Add this text:
AuthType Basic
AuthName "phpMyAdmin Users Only"
AuthUserFile /etc/phpmyadmin/.htpasswd
Require valid-user
Step 4: Create an .htpasswd File for Authentication
First we need the htpasswd utility. If you don’t already have this installed, use the following:
sudo apt-get install apache2-utils
Now we can create a secure user for our phpMyAdmin application with the command:

$ sudo htpasswd -c /etc/phpmyadmin/.htpasswd phpmyadmin
New password:
Re-type new password:
Adding password for user phpmyadmin
