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.

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:

# apt-get remove remove mariadb-server

For CentOS 7, run:

# 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
Reading package lists... Done
Building dependency tree 
Reading state information... Done
software-properties-common is already the newest version (0.96.24.32.2).
Step 2: Import MariaDB gpg key:
sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8
Executing: /tmp/apt-key-gpghome.AI8MsOQWNW/gpg.1.sh --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0xF1656F24C74CD1D8
gpg: key F1656F24C74CD1D8: 5 signatures not checked due to missing keys
gpg: key F1656F24C74CD1D8: public key "MariaDB Signing Key <signing-key@mariadb.org>" imported
gpg: Total number processed: 1
Step 3: Add the apt repository:
sudo add-apt-repository 'deb [arch=amd64] http://mirror.zol.co.zw/mariadb/repo/10.3/ubuntu bionic main'

The last step is the installation of MariaDB Server:

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

You will be prompted to provide MariaDB root password.

Enter a password to set.

Confirm password:

Press <Ok> to confirm the new password and install MariaDB. Make sure you note provided password.

Confirm MariaDB version:

$ mysql -u root -p
Enter password:

Install MariaDB 10.3 on CentOS 7

Add MariaDB YUM repository to CentOS 7 server:

# cat /etc/yum.repos.d/MariaDB.repo 
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1

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:

# yum makecache fast

Install MariaDB 10.3:

#  yum install MariaDB-server MariaDB-client

Start MariaDB service:

# systemctl start mariadb && systemctl enable mariadb

Secure MariaDB by running mysql_secure_installation.

# 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!

Log in and check MariaDB version:

]# mysql -u root -p
