Why Install WordPress on a Subdomain with Nginx?

Install WordPress on a Subdomain with Nginx

WordPress is a widely used self-hosted Content Management System (CMS) for powering blogs and general-purpose websites.

Creating a quick and dependable WordPress website necessitates the use of a trustworthy web server, such as Nginx, to provide all essential files requested by website visitors on a given domain.

This article demonstrates how to install WordPress on a subdomain and configure it to operate properly with the underlying architecture using Nginx as the web server and MySQL or MariaDB as the database server.

Requirements to Install WordPress on a Subdomain with Nginx

Before we begin, we need to have the following set up:

• Install a fresh Ubuntu 20.04 server with an LEMP stack, or deploy a Vultr One-Click LEMP server.
• Create a subdomain and point it to the server.
• Use sudo to connect to the server as a non-root user.

Setup the WordPress Database

To set up the database follow the steps givemn below:

• Firstly, Access the MySQL database server.

  $ mysql -u root -p
• Setup a new database

  mysql> CREATE DATABASE wp;
• Make a new database user with a strong password.

  mysql> CREATE USER `wpuser`@`localhost` IDENTIFIED BY ‘Strong-Password’;
• Grant full privileges to the user in the WordPress database.

  mysql> GRANT ALL PRIVILEGES ON wp.* TO 'wpuser’@’localhost';
• MySQL privileges should be refreshed.

  mysql> FLUSH PRIVILEGES
• Exit the MySQL console.

  mysql> EXIT

Install WordPress

Follow the steps given below:

• Create a new files directory in WordPress.

  $ sudo mkdir /var/www/wp.example.com
• Get the most recent WordPress release file.

  $ wget http://wordpress.org/latest.tar.gz
• Files should be extracted from the archive.

  $ tar -xzf latest.tar.gz
• Replace the extracted files in the WordPress directory.

  $ sudo mv wordpress/* /var/www/wp.example.com
• Give Nginx read and write access to the directory.

  $ sudo chown -R www-data:www-data /var/www/wp.example.com

Configure Nginx

For the setting up the Nginx:

• Firstly, In the /etc/nginx/sites-available</code >directory, create a new Nginx Server Block.

  
$ sudo touch /etc/nginx/sites-available/wp.example.com.conf

• After that, edit the server block file using any text editor.

  $ sudo nano /etc/nginx/sites-available/wp.example.com.conf
• Copy and paste the configuration lines below into the file.
  

  

  

• Check for configuration issues in Nginx.

  $ sudo nginx -t
• Link the Nginx server block to the /etc/nginx/sites-enabled directory to activate it.

  $ sudo ln -s /etc/nginx/sites-available/wp.example.com.conf /etc/nginx/sites-enabled/wp.example.com.conf
• To make changes take effect, restart Nginx.

  $ sudo systemctl nginx restart
• Finaly, launch PHP-FPM to serve PHP files from WordPress.

  $ sudo systemctl php7.4-fpm start

Security

Follow the steps given below:

• Firstly, enable HTTP and HTTPS ports to pass past the firewall.
• UFW on Debian-based systems:

  $ sudo ufw allow 80/tcp
$ sudo ufw allow 443/tcp
• FirewallD on RHEL-based systems:

  $ sudo firewall-cmd --permanent --zone=public --add-service=http. $ sudo firewall-cmd --permanent --zone=public --add-service=https.
• Install Certbot to provide HTTPS security to the WordPress site. On Debian-based machines:

  $ sudo apt install certbot python3-certbot-nginx
• After that, on RHEL-based systems type in the following:

  $ sudo yum install certbot python3-certbot-nginx
• Certbot may be used to obtain a free Let’s Encrypt SSL Certificate.

  $ sudo certbot -d wp.example.com -d www.wp.example.com
• Edit the Nginx server block file.

  $ sudo nano /etc/nginx/sites-available/wp.example.com.conf
• Finally, in the server section, add the following lines to redirect all HTTP queries to HTTPS and to limit access to important website files such as.php and.htaccess.
