MariaDB is an open source relational database management system, backward compatible, binary drop-in replacement of MySQL. It is developed by some of the original developers of the MySQL and by many people in the community. With the release of CentOS 7, MySQL was replaced with MariaDB as the default database system.
In this tutorial we will show you how to install the latest version of MariaDB on CentOS 7 using the official MariaDB repositories.
Install MariaDB 10.3 on CentOS 7
First add MariaDB yum repository in our system. Create a new repo file /etc/yum.repos.d/mariadb.repo in your system and add below code:
# MariaDB 10.3 CentOS repository list - created 2019-02-03 17:47 UTC # http://downloads.mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.3/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
Install the MariaDB server and client packages using yum, same as other CentOS package:
# sudo yum install MariaDB-server MariaDB-client
Once the installation is complete, enable MariaDB to start on boot and start the service:
# systemctl enable mariadb # systemctl start mariadb
To verify the installation check the MariaDB service status by typing:
# systemctl status mariadb
[[email protected] ~]# systemctl status mariadb ● mariadb.service - MariaDB 10.3.12 database server Loaded: loaded (/usr/lib/systemd/system/mariadb.service; enabled; vendor preset: disabled) Drop-In: /etc/systemd/system/mariadb.service.d └─migrated-from-my.cnf-settings.conf Active: active (running) since Sun 2019-02-03 17:56:25 UTC; 6s ago Docs: man:mysqld(8) https://mariadb.com/kb/en/library/systemd/
You also need to secure your MariaDB installation using passwords and do some other changes. To do this run secure installation script from command line.
The secure installation script will ask for user input as some points, follow the installation as per below output showing, All user inputs are highlighted with red color.
[[email protected] ~]# 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! 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!
Connect to MariaDB from the command line
After installing and completing the configuration, connect to MariaDB server using the following command.
# mysql -u root -p
You will be prompted to enter the root password you have previously set when the mysql_secure_installation script was run.
Once you enter the password you will be presented with the MariaDB shell as shown below:
[[email protected] ~]# mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 17 Server version: 10.3.12-MariaDB MariaDB Server Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]>
