Prerequisites for Installing WordPress on Ubuntu 22.04
Before diving into the installation process, it’s essential to ensure that your Ubuntu 22.04 system meets the necessary requirements for running WordPress. WordPress is a PHP-based application that also requires a web server and a database to function properly. Here are the prerequisites you’ll need to have in place:
- LAMP Stack: Linux, Apache, MySQL, and PHP are the components that make up the LAMP stack, which is the platform on which WordPress runs.
- Secure Shell (SSH): Access to your server via SSH is required for executing commands.
- Root Privileges: You’ll need to have root access or a user with sudo privileges to install packages and make configuration changes.
- Domain Name (optional): If you’re setting up a live website, you’ll need a registered domain name pointed to your server’s IP address.
Step 1: Installing the LAMP Stack on Ubuntu 22.04
The first step in setting up WordPress is to install the LAMP stack. This involves setting up the Apache web server, MySQL (or MariaDB) database, and PHP programming language.
Installing Apache
To install Apache, open your terminal and run the following command:
sudo apt update
sudo apt install apache2
Once the installation is complete, you can check the status of Apache with:
sudo systemctl status apache2
If Apache is running correctly, you should see an active (running) status.
Installing MySQL
Next, install MySQL with the following command:
sudo apt install mysql-server
After installation, run the secure installation script to set up basic security for your MySQL server:
sudo mysql_secure_installation
Follow the prompts to set a root password, remove anonymous users, disallow root login remotely, and remove the test database.
Installing PHP
WordPress requires PHP to execute its code. To install PHP along with commonly used extensions, use the following command:
sudo apt install php libapache2-mod-php php-mysql php-cli php-curl php-gd php-xml php-mbstring
After installing PHP, you can check the version with:
php -v
Step 2: Creating a MySQL Database and User for WordPress
WordPress uses a MySQL database to store all site data, so you’ll need to create a database and user specifically for WordPress.
Accessing MySQL
Log in to the MySQL shell with the following command:
sudo mysql -u root -p
Enter the root password you set during the MySQL secure installation when prompted.
Creating Database and User
Once logged in, create a new database for WordPress:
CREATE DATABASE wordpress_db;
Next, create a new user and grant privileges to the WordPress database:
CREATE USER 'wordpress_user'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON wordpress_db.* TO 'wordpress_user'@'localhost';
FLUSH PRIVILEGES;
EXIT;
Replace ‘password’ with a strong password of your choice.
Step 3: Installing WordPress on Ubuntu 22.04
With the LAMP stack installed and the database ready, you can now install WordPress.
Downloading WordPress
Download the latest version of WordPress using the wget command:
wget https://wordpress.org/latest.tar.gz
Next, extract the downloaded file to the Apache web root directory:
tar -xzvf latest.tar.gz
sudo mv wordpress /var/www/html/
Configuring WordPress
Navigate to the WordPress directory and rename the sample configuration file to ‘wp-config.php’:
cd /var/www/html/wordpress
sudo cp wp-config-sample.php wp-config.php
Now, edit the ‘wp-config.php’ file with your preferred text editor and update the database details:
sudo nano wp-config.php
Find the following lines and replace ‘database_name_here’, ‘username_here’, and ‘password_here’ with your database name, user, and password:
define('DB_NAME', 'wordpress_db');
define('DB_USER', 'wordpress_user');
define('DB_PASSWORD', 'password');
Setting File Permissions
Set the correct file permissions for the WordPress directory:
sudo chown -R www-data:www-data /var/www/html/wordpress
sudo find /var/www/html/wordpress/ -type d -exec chmod 750 {} ;
sudo find /var/www/html/wordpress/ -type f -exec chmod 640 {} ;
Step 4: Configuring Apache for WordPress
For Apache to serve the WordPress site, you need to set up a virtual host.
Creating Apache Virtual Host
Create a new Apache configuration file for your WordPress site:
sudo nano /etc/apache2/sites-available/wordpress.conf
Add the following configuration, replacing ‘your_domain.com’ with your actual domain name:
ServerAdmin webmaster@your_domain.com
ServerName your_domain.com
ServerAlias www.your_domain.com
DocumentRoot /var/www/html/wordpress
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
Enable the new site and disable the default site:
sudo a2ensite wordpress.conf
sudo a2dissite 000-default.conf
Enabling Apache Rewrite Module
Enable mod_rewrite for WordPress permalinks to work correctly:
sudo a2enmod rewrite
Restart Apache to apply the changes:
sudo systemctl restart apache2
Step 5: Completing the WordPress Installation Through the Web Interface
With all the server-side configuration done, you can now finalize the WordPress installation by accessing your website through a web browser.
- Open your web browser and navigate to your domain name.
- Follow the on-screen instructions to select a language, set up a site title, create an admin user, and set a password.
- Once the installation is complete, log in to the WordPress dashboard to start customizing your site.
Securing Your WordPress Installation
Security is crucial for any website. Here are some tips to secure your WordPress installation:
- Keep WordPress, themes, and plugins up to date.
- Use strong passwords and change them regularly.
- Install a security plugin to monitor and protect your site.
- Implement SSL/TLS to encrypt data transmitted between the server and users.
