In this tutorial we’ll learn how to install MariaDB on CentOS 7. We will also install and configure its prerequisites. MariaDB is a drop-in replacement for MySQL. It is developed by former members of MySQL team who concerned that Oracle might turn MySQL into a closed-source product. Many Linux distributions and companies have migrated to MariaDB.
I recommend to use a minimal Ubuntu server setup as a basis for the tutorial, that can be a virtual or a root server image with an CentOS 7 minimal install from a web hosting company or you use our minimal server tutorial to install a server from scratch.
Install MariaDB on CentOS 7
Step 1. First, ensure your system is fully up-to-date by running the following:
yum -y update
Step 2. Installing MariaDB on CentOS 7.
First, adding the MariaDB YUM repository for CentOS systems:
Now add the following lines:
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.1/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
Once MariaDB repository has been added, you can easily install the following lines:
yum install mariadb-server mariadb-client
Next, Start the MariaDB service and make it auto-start on system boot:
systemctl start mariadb.service systemctl enable mariadb.service
With MariaDB installed, we must now turn to security. The next step will perform some basic hardening on the newly-installed database server:
Follow the prompts as below:
- Would you like to setup VALIDATE PASSWORD plugin? press Enter here for No
- Please set the password for root here. New password: Type a secure password here then press Enter
- Re-enter new password: Re-type the secure password here then press Enter
- Remove anonymous users? (Press y|Y for Yes, any other key for No) : press y and then Enter here
- Disallow root login remotely? (Press y|Y for Yes, any other key for No) : press y and then Enter here
- Remove test database and access to it? (Press y|Y for Yes, any other key for No) : press y and then Enter here
- Reload privilege tables now? (Press y|Y for Yes, any other key for No) : press y and then Enter here
Once the database server is secured, check itâs installed version and login to the MariaDB command shell as follows:
To access the MariaDB instance, run the following command on the terminal.
mysql -u root -p
Congratulation’s! You have successfully configured MariaDB on your CentOS 7 server.
