At the time of writing, MariaDB 10.1 is the development version of MariaDB. It is based on MariaDB 5.5, and includes back-ported features from MySQL 5.6. There are also new features that are exclusive to MariaDB.
For CentOS, RedHat, and Fedora, it is highly recommended to install from a repository using yum. This guide will walk you through the installation steps for CentOS 6.
Add the MariaDB repository
First, ensure the list of available packages is up-to-date before installing. Open your SSH terminal and input the following commands.
yum -y update
Add the MariaDB repository.
For 32-bit users, paste the following text:
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.1/centos6-x86 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
For 64-bit users, paste the following text:
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.1/centos6-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
At this point, installing MariaDB is as simple as running just one command.
yum install MariaDB-server MariaDB-client -y
Once the installation completes, start MariaDB.
service mysql start
Next, set MariaDB to start on every boot.
chkconfig mysql on
Secure your MariaDB installation. The following checklist shows the steps that will be performed.
- Set (Change) root password.
- Remove anonymous users.
- Disallow root login remotely.
- Remove test database and access to it.
- Reload privilege tables.
Run the secure installation command.
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: ENTER YOUR PASSWORD Re-enter new password: REPEAT YOUR 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!
