Prerequisites

Before we start, make sure you have the following:

  • A virtual private server (VPS) or dedicated server running Caddy
  • A domain name that you control
  • A MySQL or MariaDB database ready for WordPress
  • A domain name (optional)

Step 1: Installing Caddy

If you have not installed Caddy on your server, you need to do so. Depending on your server’s operating system, the installation process might differ. Caddy’s officialinstallation guideprovides comprehensive instructions.

Step 2: Configuring Caddy for WordPress

You will need to configure Caddy to work with WordPress. Create or modify a Caddyfile, Caddy’s configuration file, to include your website details:

yourdomain.com {
    root * /var/www/html
    encode gzip
    file_server
    php_fastcgi unix//run/php/php8.0-fpm.sock
}

Remember to replace ‘yourdomain.com’ with your actual domain and adjust the root path and PHP FastCGI directive according to your server setup.

Step 3: Downloading WordPress

Next, download the latest WordPress package and extract it:

cd /var/www/html
wget https://wordpress.org/latest.tar.gz
tar -xzvf latest.tar.gz
mv wordpress/* ./
rm -rf wordpress latest.tar.gz

Ensure to adjust the directory paths as per your setup.

Step 4: Creating the WordPress Database

You’ll need to create a database for WordPress. Log in to your MySQL or MariaDB server and create a new database and user:

CREATE DATABASE wordpress;
CREATE USER 'wordpressuser'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpressuser'@'localhost';
FLUSH PRIVILEGES;
exit

Replace ‘wordpress’, ‘wordpressuser’, and ‘password’ with your database name, username, and password, respectively.

Step 5: Installing WordPress

Now, you can run the WordPress installation. Open a web browser and navigate to your domain name. You should see the WordPress installation wizard. Follow the prompts, entering your database information when asked.

Step 6. Configuring WordPress
