sudo systemctl start httpd && systemctl start mariadb

sudo systemctl enable httpd && systemctl enable mariadb 

Create a MySQL Database and user for WordPress

sudo mysql -u root -p

Creating a New WordPress Database

To get started with WordPress, the first step is to set up a new database that WordPress will manage. This database will store all your website's necessary information, from user data to content posts. Follow the steps below to create your new database:

To create a new account, use the username user_name and assign it the password

CREATE USER 'username'@'host' IDENTIFIED BY 'password';

Granting Database Access to the WordPress User

Now that you have created a dedicated database and user for WordPress, the next step is to grant the user access to the database. This is crucial for enabling the WordPress installation to interact with its database. Follow these steps to establish the necessary permissions:

1. Log in to your database management interface, such as phpMyAdmin.

2. Select the database you created for WordPress from the list on the left-hand side.

3. Click on the "Privileges" or "Users" tab, depending on your interface.

4. Find and click on the "Add user to database" option.

5. In the drop-down menus, select the WordPress user and the WordPress database.

6. Grant all privileges to the user for this database by checking the option "ALL PRIVILEGES".

7. Click on the "Make changes" or "Save" button to apply the permissions.

With these steps, your WordPress user now has full access to its database, allowing for a smooth WordPress installation and operation.

GRANT ALL PRIVILEGES ON database.* TO 'username'@'host' IDENTIFIED BY 'Password@123$#@' WITH GRANT OPTION;

To ensure MySQL recognizes the recent changes to privileges, it's necessary to flush the privileges.

FLUSH PRIVILEGES;
