1. Install Apache

WordPress CMS requires a web server and Apache2 HTTP server is the most popular open source web server available today… To install Apache2 server, run the commands below:

2. Install MariaDB

WordPress also requires a database server to store its content. If you're looking for a truly open source database server, then MariaDB is a great place to start. 

To install MariaDB run the commands below:

$ sudo apt-get install mariadb-server mariadb-client

After installing MariaDB, the commands below can be used to stop, start and enable MariaDB service to always start up when the server boots.

For Ubuntu 16.04 LTS, execute the following commands to stop, start and enable MariaDB service respectively:

$ sudo systemctl stop mysql.service
$ sudo systemctl start mysql.service
$ sudo systemctl enable mysql.service

For Ubuntu 18.10 and 18.04 LTS, run the following commands to do same:

$ sudo systemctl stop mariadb.service
$ sudo systemctl start mariadb.service
$ sudo systemctl enable mariadb.service

Next, run the commands below to secure the database server with a root password if you were not prompted to do so during the installation:

$ sudo mysql_secure_installation

When prompted, answer the questions below by following the guide:

Enter current password for root (enter for none): Just press the Enter
Set root password? [Y/n]: Y
New password: Enter password
Re-enter new password: Repeat password
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]:  Y
Reload privilege tables now? [Y/n]:  Y

Now that MariaDB is installed, to test whether the database server was successfully installed, run the commands below:

$ sudo mysql -u root -p

Then type the root password when prompted. 

3. Install PHP 7.2 and Related Modules

WordPress CMS is a PHP based CMS and PHP is required. However, PHP 7.2 may not be available in Ubuntu default repositories.

Every time you make changes to PHP configuration file, you should also restart Apache2 web server.

To do so, run the commands below:

$ sudo systemctl restart apache2.service

Now that PHP is installed, to test whether it's functioning, create a test file called phpinfo.php in Apache2 default root directory "( /var/www/html/)":

$ sudo nano /var/www/html/phpinfo.php

Then type the content below and save the file:

<?php phpinfo( ); ?>

Next, open your browser and browse to the server's hostname or IP address followed by phpinfo.php:


Now, You should see PHP default test page.
