sudo mkdir /var/www/wordpress
# 1.1. Create a configuration file for our web server
sudo nano /etc/apache2/sites-available/x11.xyz.conf
#____________________________________________________________________
<VirtualHost *:80>
        ServerAdmin postmaster@x11.xyz
        ServerName www.x11.xyz
        ServerAlias x11.xyz
        DocumentRoot /var/www/wordpress
        ErrorLog ${APACHE_LOG_DIR}/x11.xyz-error.log

# 1.3. Reload apache
sudo systemctl reload apache2

2. Create a MariaDB DB User for WordPress

# 2.1. Login to MariaDB
mariadb -u root -p
# 2.2. Create a database named as wordpress, create a user named as wordpressuser
#      and give the user necessarry permissions for the database.
CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8 COLLATE utf8_unicode_ci;
CREATE USER 'wordpressuser'@'localhost' IDENTIFIED BY 'pAsswOrd1234';
GRANT ALL ON wordpress.* TO 'wordpressuser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

3. Install Additional PHP Extensions

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

4. Adjust Apache for WordPress

# 4.1. Enable wordpress' .htaccess files
#      by editing our site config, adding folders to override
sudo nano /etc/apache2/sites-available/x11.xyz.conf

5. Download WordPress

#    WordPress can be installed by apt install, but 
#      we prefer to download the latest version from the original source
# 5.1. Go to temp directory, download wordpress, extract it
cd /tmp
curl -O https://wordpress.org/latest.tar.gz
tar xzvf latest.tar.gz
# 5.2. Before copying to its home we need to make some additions
#   Create a dummy .htaccess file
touch /tmp/wordpress/.htaccess
#   Copy sample config file to real config file
cp /tmp/wordpress/wp-config-sample.php /tmp/wordpress/wp-config.php
# 5.3. Copy wordpress files to their location
sudo cp -a /tmp/wordpress/. /var/www/wordpress

6. Configure WordPress Directory

# 6.1. Set ownerships and permissions
#     Owned by www-data:www-data
sudo chown -R www-data:www-data /var/www/wordpress
#     All files 640, all dirs 750
sudo find /var/www/wordpress/ -type d -exec chmod 750 {} \;
sudo find /var/www/wordpress/ -type f -exec chmod 640 {} \;
# 6.2. Setup wordpress config file
# 6.2.1. Generate secure phrases
#    WP requires some secure phrases for security, we will create them now
curl -s https://api.wordpress.org/secret-key/1.1/salt/
#    The output of this program will be something like following:
#    Copy them into a text file
