We are assuming that you have root permission, otherwise, you may start commands with “sudo”.

Before You Begin

You have to update your repositories cache to get the latest versions. execute:

 apt‐get update

Install and configure Apache 2.4

Install apache 2.4:

 apt-get install apache2

You can change the configurations using a text editor (Optional)

 nano /etc/apache2/apache2.conf

And after changing the configurations you should restart apache2:

 systemctl restart apache2

Install MySQL

For installing MySQL type:

 apt‐get install mysql‐server

Input a secure password when prompted by the installation.
Run secure installation to remove the test database and any user permissions added during the installation.

 mysql_secure_installation

It’s recommended to select yes (y) for all questions. if you already have a secure root password you don’t need to change it.

Setup MySQL Database

Now you can create a database and grant your users permissions.
Login to MySQL:

 mysql ‐u root ‐p

For creating a database and granting permissions to users you can use following commands: (you may change the values of “dbname”,”username”,”password” to your own values)

mysql> create database dbname;
-> grant all on dbname.* to 'username' identified by 'password';

Exit MySQL

mysql> quit

Install PHP

In this section, we have 2 options to install PHP 7 or PHP 5, the official repository of  Ubuntu 16 only provides PHP 7 at the moment, as you will see we have to add an unofficial repository in order to install PHP 5.

Install PHP 7

Install PHP with the following command:

 apt-get install php7.0-mysql php7.0-curl php7.0-json php7.0-cgi  php7.0 libapache2-mod-php7.0

Now it’s time to test the PHP software that you just installed. move to your public web directory:

 cd /var/www/html

Now use your favorite text editor to create a file named info.php

 nano info.php

Inside that file, type the following:

<?php phpinfo(); ?>

Install PHP 5.6

In this tutorial we are using PPA repository:

apt-get install python-software-properties
add-apt-repository ppa:ondrej/php
apt-get update
apt-get install -y php5.6

Now you have to make our Apache to work with PHP 5:

a2enmod php5.6
systemctl restart apache2

Finally, we are going to test our PHP5:
move to your public web directory:

 cd /var/www/html

Now use your favorite text editor to create a file named info.php

 nano info.php

Inside that file, type the following:

<?php phpinfo(); ?>
