In this article, we will focus on how to install WordPress on Ubuntu 18.04. WordPress is a free and open-source content management platform based on PHP and MySQL. It’s the world’s leading blogging and content management system with a market share of over 60%, dwarfing its rivals such as Joomla and Drupal. WordPress was first released on May 27th, 2003 and powers over 60 million websites to date! So powerful and popular it has become that some major brands/companies have hosted their sites on the platform. These include Sony Music, Katy Perry, New York Post, and TED.

So why is WordPress this popular? Let’s briefly look into some of the factors that have led to the immense success of the platform.

Ease of Use

WordPress comes with a simple, intuitive and easy to use dashboard. The dashboard doesn’t require any knowledge in web programming languages like PHP, HTML5, and CSS3 and you can build a website with just a few clicks on a button. In addition, there are free templates, widgets, and plugins that come with the platform to help you get started with your blog or website.

Cost effectiveness

WordPress drastically saves you the agony of having to pay developer tonnes of cash to develop your website. All you have to do is to get a free WordPress theme or purchase one and install it. Once installed, you have the freedom to deploy whatever features that suit you and customize a myriad of features without running much code. What’s more, is that it takes a much shorter time to design your site that coding from scratch.

WordPress sites are Responsive

WordPress platform is inherently responsive and you do not have to stay awake worrying about your sites being able to fit across multiple devices. This benefit also adds to your site being ranked higher in Google’s SEO score!

WordPress is SEO ready

WordPress is built using well-structured, clean and consistent code. This makes your blog/site easily indexable by Google and other search engines thereby making your site rank higher. In addition, you can decide which pages rank higher or alternatively use SEO plugins like the popular Yoast plugin which enhances your site’s ranking on Google.

Easy to install and upgrade

It’s very easy to install WordPress on Ubuntu or any other operating system. There are so many open-source scripts to even automate this process. Many hosting companies provide a one-click install feature for WordPress to get you started in no time.

Install WordPress on Ubuntu 18.04

Before we begin, let’s update and upgrade the system. Login as the root user to your system and update the system to update the repositories.

apt update && apt upgrade

Output update and upgrade the ubuntu system Next, we are going to install the LAMP stack for WordPress to function. LAMP is short for Linux Apache MySQL and PHP.

Step 1: Install Apache

Let’s jump right in and install Apache first. To do this, execute the following command.

apt install apache2

Output Install Apache2 To confirm that Apache is installed on your system, execute the following command.

systemctl status apache2

Output how to check apache2 status To verify further, open your browser and go to your server’s IP address.

https://ip-address

Output Apache Web Server Default Page

Step 2: Install MySQL

Next, we are going to install the MariaDB database engine to hold our Wordpress files. MariaDB is an open-source fork of MySQL and most of the hosting companies use it instead of MySQL.

apt install mariadb-server mariadb-client

Output Install MySQL Mariadb Server Mariadb Client Let’s now secure our MariaDB database engine and disallow remote root login.

$ mysql_secure_installation

The first step will prompt you to change the root password to login to the database. You can opt to change it or skip if you are convinced that you have a strong password. To skip changing type n. Change The Root Password For safety’s sake, you will be prompted to remove anonymous users. Type Y. Remove Anonymous Users Next, disallow remote root login to prevent hackers from accessing your database. However, for testing purposes, you may want to allow log in remotely if you are configuring a virtual server Disallow Root Login Remotely Next, remove the test database. Remove Test Database Finally, reload the database to effect the changes. Reload Privilege Table

Step 3: Install PHP

Lastly, we will install PHP as the last component of the LAMP stack.

apt install php php-mysql

Output Install Php To confirm that PHP is installed , created a info.php file at /var/www/html/ path

vim /var/www/html/info.php

Append the following lines:

<?php
phpinfo();
?>

Save and Exit. Open your browser and append /info.php to the server’s URL.

https://ip-address/info.php

Output Info Php Webpage

Step 4: Create WordPress Database

Now it’s time to log in to our MariaDB database as root and create a database for accommodating our WordPress data.

$ mysql -u root -p

Output Mysql Root Login Create a database for our WordPress installation.

CREATE DATABASE wordpress_db;

Output Create Wordpress Database Next, create a database user for our WordPress setup.

CREATE USER 'wp_user'@'localhost' IDENTIFIED BY 'password';

Output Create User For Wordpress Database Grant privileges to the user Next, grant the user permissions to access the database

GRANT ALL ON wordpress_db.* TO 'wp_user'@'localhost' IDENTIFIED BY 'password';

Output Grant Privileges To Wp User On Wordpress Database Great, now you can exit the database.

FLUSH PRIVILEGES;

Exit;

Step 5: Install WordPress CMS

Go to your temp directory and download the latest WordPress File

cd /tmp && wget https://wordpress.org/latest.tar.gz

Output Download Wordpress Next, Uncompress the tarball which will generate a folder called “wordpress”.

tar -xvf latest.tar.gz

Output Uncompress Wordpress Tarball Copy the wordpress folder to /var/www/html/ path.

cp -R wordpress /var/www/html/

Run the command below to change ownership of ‘wordpress’ directory.

chown -R www-data:www-data /var/www/html/wordpress/

change File permissions of the WordPress folder.

chmod -R 755 /var/www/html/wordpress/

Create ‘uploads’ directory.

$ mkdir /var/www/html/wordpress/wp-content/uploads

Finally, change permissions of ‘uploads’ directory.

chown -R www-data:www-data /var/www/html/wordpress/wp-content/uploads/

Open your browser and go to the server’s URL. In my case it’s

https://server-ip/wordpress

You’ll be presented with a WordPress wizard and a list of credentials required to successfully set it up. install wordpress on ubuntu 18.04 Fill out the form as shown with the credentials specified when creating the WordPress database in the MariaDB database.

the best tutor ever thanks

- muhammad afnan afif

    Uh hello. I’ve just finished installing WordPress on my webserver. Everything worked fine for some minutes, then, out of the nowhere, it tells me “Error establishing a database connection”. I have done everything exactly like you (except setting up Apache2, I already did that way before). Where am I/did go wrong? Could anyone give me a solution/explanation if possible? However, this is a great tutorial. If you would include some troubleshooting with (probably) common errors like this, it would be even way better! Thanks in advance, Saintly.
