We have to setup two server one for database and one for WordPress file.

#database server setup.

step 1: Buy an instance from any cloud platform based on the required storage and other specifications.
step 2: Set up the database server:
- #install MySQL

commands: sudo apt update && upgrade -y
sudo apt install mysql-server
sudo mysql_secure_installation #' set or change the root password for the MYSQL server'

- #Configure MySQL

commands: #Edit the configuration file /etc/mysql/my.cnf for MySQL
[mysqld]
bind-address = 0.0.0.0

sudo systemctl restart mysql

#Create Database and User

sudo mysql -u root -p
CREATE DATABASE wordpress_db;
CREATE USER 'wp_user'@'%' IDENTIFIED BY 'your_password';
GRANT ALL PRIVILEGES ON wordpress_db.* TO 'wp_user'@'%';
FLUSH PRIVILEGES;
EXIT;

#Configure Firewall

command: sudo ufw allow 3306

#wordpress file server setup:

- Buy another instance from the same cloud platform used for the database server.

commands: sudo apt update && upgrade -y
