This article will guide through installing MariaDB server and its configuration on CentOS7/RHEL7. The assumption for this article is that you are using a clean build of CentOS7. Let’s start with setting up the repo for MariaDB.
Go ahead and setup MariaDB repo for the download.
# vi /etc/yum.repos.d/MariaDB.repo [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.1/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
Now download MariaDB
# yum -y install MariaDB-server
Now enable it start at boot and start the service
# openssl req -text -noout -verify -in testwps.off.local.csr | grep -A2 Alternative
Now securely configure MariaDB
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?

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.

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!
