This guide is to help you get MariaDB 10.3 running on CentOS 7 and Ubuntu 18.04 server. As of this writing, the latest stable release of MariaDB is 10.3.  The default version of MariaDB installed on CentOS 7 is 5.5 and  MariaDB 10.1 for Ubuntu 18.04. These versions are available on OS upstream repositories.

For Debian 9 / Debian use How to Install MariaDB 10.3 on Debian 9 / Debian 8

For Ubuntu 16.04 use How to install MariaDB 10.3 on Ubuntu 16.04 LTS (Xenial)

Before you can install MariaDB 10.3, you may need to uninstall the current version of MariaDB server. You can ignore this if upgrading.  On Ubuntu, run:

sudo apt-get remove mariadb-server

For CentOS 7, run:

sudo yum remove mariadb-server

Install MariaDB 10.3 on Ubuntu 18.04

To install MariaDB 10.3 on Ubuntu 18.04, you need to add MariaDB repository on to the system.

Step 1: Install software-properties-common if missing:

sudo apt-get install software-properties-common

Step 2: Import MariaDB gpg key:

Run the command below to add Repository Key to the system

sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8

Step 3: Add the apt repository

Once the PGP key is imported, proceed to add repository URL to your Ubuntu 18.04 server:

sudo add-apt-repository 'deb [arch=amd64] http://mirror.zol.co.zw/mariadb/repo/10.3/ubuntu bionic main'

Step 4: Install MariaDB

The last step is the installation of MariaDB Server:

sudo apt update
sudo apt -y install mariadb-server mariadb-client

You will be prompted to provide MariaDB root password.

Step 5: Install Desktop Database Management Tool

If working with MySQL command line is not your thing, then consider installing a Database Tool to help you. Check out our guide below:

Install and Configure DBeaver on Ubuntu 18.04 / Ubuntu 16.04 / Debian 9

For phpMyAdmin, use our guide below:

Install MariaDB 10.3 on CentOS 7

Add MariaDB YUM repository to CentOS 7 server:

cat <<EOF | sudo tee /etc/yum.repos.d/MariaDB.repo
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64

To install other versions of MariaDB like 10.1 or 10.2 replace 10.3 with the other version on baseurl.

Clean yum cache index:

sudo yum makecache fast

Install MariaDB 10.3:

sudo yum -y install MariaDB-server MariaDB-client

Start MariaDB service:

sudo systemctl start mariadb
sudo systemctl enable mariadb

Secure MariaDB by running mysql_secure_installation.

# mysql_secure_installation 


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!

# mysql -u root -p
