Install WordPress on Apache & Ubuntu 22.04

WordPress is by far the most popular Content Management System (CMS) in the world with over 455 million websites using it, and with over 55,000 plugins available, it’s extremely flexible too. Today’ I’ll show you how to install WordPress on an Ubuntu 22.04 LAMP stack.

This article is part of my series The Ultimate Web Server.



Create a new MySQL Database & User

Before we start uploading files, we need to create a new MySQL database and user for your WordPress installation. Open your SSH client and login to your server with a non-root user with sudo privileges. Then we login to the MySQL:

sudo mysql -uroot -p

Next, we create a database for WordPress. I am calling my database wpress but you can call it anything you like:


Let’s create a MySQL user for WordPress and grant privileges required to access the WordPress database, then flush privileges, and exit MySQL. My users name is wpuser, but you can use any name you like. Replace password with a strong password of your choosing:

CREATE USER 'wpuser'@'%' IDENTIFIED WITH mysql_native_password BY 'password';
GRANT ALL ON wpress.* TO 'wpuser'@'%';

Install Required PHP Extensions

WordPress requires certain PHP extensions to be installed. Let’s update the package cache first, install required extensions, and restart Apache. If a module is already installed, the apt package manager will simply skip it:

sudo apt update
sudo apt install php-curl php-gd php-xml php-xmlrpc php-mbstring php-soap php-intl php-zip
sudo systemctl restart apache2

Allow .htaccess Files in Apache

If you’re following my guide The Ultimate Web Server then you will already have a website set-up with an SSL certificate, Apache Virtual Hosts, and a .conf file inside the /etc/apache2/sites-available/ folder (in my guide I use /etc/apache2/sites-available/

If you haven’t setup Virtual Hosts, you will need to edit the default configuration file located in /etc/apache2/sites-available/000-default.conf and upload files to the default /var/www/html directory instead.

Open your websites configuration file replacing with your website file (or the default file 000-default.conf). If you have already installed Let’s Encrypt SSL certificate, the default .conf file with be (replace with your website):

sudo nano /etc/apache2/sites-available/

Under the <VirutalHost *:443> grouping, copy and paste the following code replacing with your websites directory (found under /var/www/ folder):

    <Directory /var/www/>
        AllowOverride All

Then save ctrl + o, ENTER and exit nano ctrl + x and restart Apache:

Enabling Mod-Rewrite

WordPress makes use of the Apache mod_rewrite module for pretty permalinks, so instead of you can have more human-readable URLs like Let’s enable them:

sudo a2enmod rewrite

Now let’s test the new configuration:

sudo apache2ctl configtest
Apache configtest result - Syntax OK

You should see Syntax OK. If not, go back to your websites .conf file and make sure the directives are correct. Let’s restart Apache to implement the changes:

sudo systemctl restart apache2

Download and Install WordPress

We will be downloading WordPress to a temporary location, then create some configuration files, and finally copy the directory to your websites root folder. Head over to the writeable /tmp directory:

cd /tmp

Download the latest WordPress release:

curl -O

Extract the compressed folder use the built-in tar archiver:

tar xzvf latest.tar.gz

Create a blank .htaccess file inside the new WordPress directory:

touch /tmp/wordpress/.htaccess

Create the configuration file by copying the sample config file:

cp /tmp/wordpress/wp-config-sample.php /tmp/wordpress/wp-config.php

Create an upgrade folder so WordPress doesn’t run into any permission errors later:

mkdir /tmp/wordpress/wp-content/upgrade

Now copy the WordPress folder into your website root folder. In my case it’s /var/www/ Replace with your folder name:

sudo cp -a /tmp/wordpress/. /var/www/

Configure Directory & File Permissions

By default, the files and folders we just copied over are owned by your non-root user, but we need them to be owned by the web server account www-data. We also need to change file and folder permissions for WordPress to work:

First, we change ownership of all the files and folders using the chown command:

sudo chown -R www-data:www-data /var/www/

Now change folder/directory permissions to 755 using the chmod command:

sudo find /var/www/ -type d -exec chmod 755 {} \;

Then change file permissions to 644:

sudo find /var/www/ -type f -exec chmod 644 {} \;

Setting up the WordPress Config File

WordPress provides a free tool to create a unique “Salt” or secret keys that are used to secure your WordPress installation. Enter the following code to generate your unique keys:

curl -s
Generate a unique set of Salt keys for WordPress

Copy the generated data to clipboard and paste them into a text file on you local PC, then open the WordPress configuration file:

sudo nano /var/www/

Using your arrow keys, scroll down to the “Authentication and salt keys” section, and copy and paste the generated values to the corresponding lines inside the ‘put your unique phrase here’ brackets (i.e. “AUTH_KEY” value to “AUTH_KEY” line).

Auth Keys blank

It should look similar to this:

Auth Keys filled

Scroll up to the Database Settings and enter your database information (replace my values with your own):

  • Database name – wpress
  • Database User – wpuser
  • Database Password – password
Database name, user and password

For extra security, add some random numbers or letters to your table prefix so it’s not easy for a hacker to guess. Scroll down to the Table Prefix section and add either numbers or letters between wp and the underscore _:

Change the WordPress table prefix

If you’ve been following my guide The Ultimate Web Server you may have an index.html file inside your website’s root folder. We need to delete it:

sudo rm -rf /var/www/

Installing WordPress

Open your web browser and enter your website URL. In my case it’s You’ll be presented with the WordPress installation page. Choose your language, then enter your information (be sure to record your username and password). Some tips on usernames and passwords:

  • Always append a username with random data (numbers and letters) and never use “Admin” or “Administrator” as they’re easy to guess. A good username for me would be: richie_8sxd23r7
  • Use a strong password with letters, numbers and special characters. WordPress can generate one for you. Click the “Show” button and keep a record of it

Once you have finished entering your information, click the “Install WordPress” button. You will then be asked to login with your new user.

Install WordPress
