In this post, I will show you how to install MariaDB on a CentOS/RHEL 7 machine. This task is really easy to complete and could be done in couple minutes.
Installing the Software###
[[email protected] ~]# yum install mariadb-server
Enabling and starting the service
To enable the service and making it persistent across reboots:
[[email protected] ~]# systemctl enable mariadb.service
To start the service:
[[email protected] ~]# systemctl start mariadb.service
Basic MariaDB configuration###
Now we are going to do some basic configuration. To do this we will execute the mysql_secure_installation script. To do this run:
[[email protected] ~]# mysql_secure_installation
Here are some steps to follow:
[[email protected] ~]# mysql_secure_installation /bin/mysql_secure_installation: line 379: find_mysql_client: command not found 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! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? [Y/n] Y ... Success! Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? [Y/n] Y ... Success! By default, MariaDB comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? [Y/n] Y - Dropping test database... ... Success! - Removing privileges on test database... ... Success! Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? [Y/n] Y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!
After this we are going to test that we could connect to the MariaDB server:
[[email protected] ~]# mysql -u root -p
We are done, we have installed and configured MariaDB on CentOS/RHEL.
