Once the installation is complete, enable MariaDB (to start automatically upon system boot), start the MariaDB and verify the status using the commands below.

systemctl enable mariadb

systemctl start mariadb

Secure your MariaDB server

---

You must secure the MariaDB server by running the following command for production use.

mysql_secure_installation

Output:

[root@vps ~]# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user.  If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
 ... Success!

Now, log in to the MariaDB server.

To login to the MariaDB server, enter the following command with the password set previously,

mysql -u root -p

Output:

[root@vps ~]# mysql -u root -p
Enter password:

Create new DataBase and User

---

Here, we'll look into creating new database, new database user and add the user to database. (eg: Here we'll cerate database called "crowncloud" and the new user called "ccuser1"),

First, log in as root user:

mysql -u root -p

CREATE DATABASE crowncloud;

CREATE user ccuser1;

GRANT ALL ON crowncloud.* TO ccuser1@localhost IDENTIFIED BY 'secretePasswordHere';

Output:

[root@vps ~]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 19
Server version: 10.3.17-MariaDB MariaDB Server

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]> CREATE DATABASE crowncloud;
Query OK, 1 row affected (0.002 sec)

MariaDB [(none)]> CREATE user ccuser1;
Query OK, 0 rows affected (0.004 sec)

MariaDB [(none)]> GRANT ALL ON crowncloud.* TO ccuser1@localhost IDENTIFIED BY 'secretePasswordHere';
Query OK, 0 rows affected (0.004 sec)

Accessing the database

---

Now, we will access MariaDB with the newly created Database and User as shown below,

mysql -u ccuser1 -p'secretePasswordHere' crowncloud

show databases;

Output:

[root@vps ~]# mysql -u ccuser1 -p'secretePasswordHere' crowncloud
