This brief tutorial is going to show students and new users how to install WordPress CMS on Ubuntu 16.04 / 18.10 and 18.04 LTS…

To get started with installing WordPress, follow the steps below:

Step 1: Install Apache2 HTTP Server

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:

sudo apt update
sudo apt install apache2

After installing Apache2, the commands below can be used to stop, start and enable Apache2 service to always start up with the server boots…

sudo systemctl stop apache2.service
sudo systemctl start apache2.service
sudo systemctl enable apache2.service

Now that Apache2 is installed…. to test whether the web server is working, open your browser and browse to the URL below…

http://localhost

If you see the page above, then Apache2 is successfully installed…

Step 2: Install MariaDB Database Server

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…

Run these on Ubuntu 16.04 LTS

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

Run these on Ubuntu 18.10 and 18.04 LTS

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

type the root password when prompted…

mariadb welcome

If you see a similar screen as shown above, then the server was successfully installed…

Step 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… To run PHP 7.2 on Ubuntu 16.04 and previous, you may need to run the commands below:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:ondrej/php

Then update and upgrade to PHP 7.2

sudo apt update

Next, run the commands below to install PHP 7.2 and related modules.

sudo apt install php7.2 libapache2-mod-php7.2 php7.2-common php7.2-mysql php7.2-gmp php7.2-curl php7.2-intl php7.2-mbstring php7.2-xmlrpc php7.2-gd php7.2-xml php7.2-cli php7.2-zip

After installing PHP 7.2, run the commands below to open PHP default configuration file for Apache2…

sudo nano /etc/php/7.2/apache2/php.ini

The lines below is a good settings for most PHP based CMS… Update the configuration file with these and save….

file_uploads = On
allow_url_fopen = On
short_open_tag = On
memory_limit = 256M
upload_max_filesize = 100M
max_execution_time = 360
date.timezone = America/Chicago

Everytime 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

http://localhost/phpinfo.php

You should see PHP default test page…

Step 4: Create WordPress Database

Now that you’ve installed all the packages that are required for WordPress to function, continue below to start configuring the servers. First run the commands below to create a blank WordPress database.

To logon to MariaDB database server, run the commands below.

sudo mysql -u root -p

Then create a database called wordpress

CREATE DATABASE wordpress;

Create a database user called wordpressuser with a new password

CREATE USER 'wordpressuser'@'localhost' IDENTIFIED BY 'new_password_here';

Then grant the user full access to the database.

GRANT ALL ON wordpress.* TO 'wordpressuser'@'localhost' IDENTIFIED BY 'user_password_here' WITH GRANT OPTION;

Finally, save your changes and exit.

FLUSH PRIVILEGES;
EXIT;

Step 5: Download WordPress Latest Release

To get WordPress latest release you will need to go to its official download page and get it from there… The link below is where to find WordPress latest archive versions…

https://wordpress.org/download/

cd /tmp
wget https://wordpress.org/latest.tar.gz
tar -xvzf latest.tar.gz
sudo mv wordpress /var/www/html/wordpress

Then run the commands below to set the correct permissions for WordPress root directory and give Apache2 control….

sudo chown -R www-data:www-data /var/www/html/wordpress/
sudo chmod -R 755 /var/www/html/wordpress/

Step 6: Configure Apache2

Finally, configure Apahce2 site configuration file for WordPress. This file will control how users access WordPress content. Run the commands below to create a new configuration file called wordpress.conf

sudo nano /etc/apache2/sites-available/wordpress.conf

Then copy and paste the content below into the file and save it. Replace the highlighted line with your own domain name and directory root location.

<VirtualHost *:80>
     ServerAdmin admin@example.com
     DocumentRoot /var/www/html/wordpress
     ServerName example.com
     ServerAlias www.example.com

     <Directory /var/www/html/wordpress/>
          Options FollowSymlinks
          AllowOverride All
          Require all granted
     </Directory>

     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined
    
     <Directory /var/www/html/wordpress/>
            RewriteEngine on
            RewriteBase /
            RewriteCond %{REQUEST_FILENAME} !-f
            RewriteRule ^(.*) index.php [PT,L]
    </Directory>
</VirtualHost>

Save the file and exit.

Step 7: Enable the WordPress and Rewrite Module

After configuring the VirtualHost above, enable it by running the commands below

sudo a2ensite wordpress.conf
sudo a2enmod rewrite
sudo systemctl restart apache2.service

Then open your browser and browse to the server domain name. You should see WordPress setup wizard to complete. Please follow the wizard carefully.

http://example.com/

Then follow the on-screen instructions… Select the installation language then click Continue

WordPress Ubuntu Installation

You will need to know the following items before proceeding…. Use the database connection info you created above….

  • Database name
  • Database username
  • Database password
  • Database host
  • Table prefix (if you want to run more than one WordPress in a single database)

The wizard will use the database information to create a wp-config.php file in WordPress root folder….

If for any reason this automatic file creation doesn’t work, don’t worry… All this does is fill in the database information to a configuration file. You may also simply open wp-config-sample.php in a text editor, fill in your information, and save it as wp-config.php.

Next, type in the database connection info and click Submit
