manually with this path /etc/yum.repos.d/
, To create a MariaDB repository file, you can use the following command,
vi /etc/yum.repos.d/mariadb.repo

Once the installation is complete, you can verify the version of the MariaDB server by using the following command:
mysql -V
Output:
[root@vps ~]# mysql -V
mysql Ver 15.1 Distrib 10.11.5-MariaDB, for Linux (x86_64) using readline 5.1
[root@vps ~]#
Now, 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
systemctl status mariadb
Output:
[root@vps etc]# systemctl status mariadb

Secure your MariaDB server
You can secure your MariaDB installation by following these steps
Start the MariaDB shell:
mysql
Change the root user's password:
ALTER USER 'root'@'localhost' IDENTIFIED BY 'your_new_password';
Replace 'your_new_password' with the password you want to set for the root user.
Remove anonymous users:
DELETE FROM mysql.user WHERE User='';
Disallow remote root login. This ensures that the root user can only log in from the localhost:
DELETE FROM mysql.user WHERE User='root' AND Host NOT IN ('localhost', '127.0.0.1', '::1');
Remove the test database:
DROP DATABASE IF EXISTS test;
Reload the privileges to apply the changes:
FLUSH PRIVILEGES;
Exit the MariaDB shell:
EXIT;
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:

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
