SystemMen - This article will show you how to install MariaDB 10.3 in CentOS 6. Version 10.3 is the latest MariaDB version at this time.
Configure server requirements
The following is the recommended configuration to use the server when installing MariaDB.
- OS: CentOS 6.10 (Final) 64bit.

- HDD: free more then 5GB space. Most providers now offer 20 GB of disk for 1GB RAM VPS, so you don’t need to worry about it.

Add MariaDB repository to the server
To install MariaDB via yum and be convenient for later updates, we add MariaDB repository to the server.
MariaDB provides a page that allows you to select the operating system and configure the corresponding repository.
We create a file named MariaDB.repo with the following command.
# yum install nano -y && nano /etc/yum.repos.d/MariaDB.repo
And then copy the content below to the file just created above, save the file.
# MariaDB 10.3 CentOS repository list - created 2019-02-28 03:04 UTC # http://downloads.mariadb.org/mariadb/repositories/ [mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.3/centos6-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
Then update new packages from MariaDB repository.

This process look like below.
[root@cent6 ~]# 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!

Open port 3306 in IPtables
MariaDB’s mysql service runs the default port of 3306. If you want to connect from other servers to this database server, you need to open the port on the IPtables firewall.
Warning: You only open port 3306 when needed. If you run a web server type all-in-one combination database, you do not need to do this.
Type the following command to add a rule to IPtables.
# iptables -I INPUT 1 -m tcp -p tcp --dport 3306 -j ACCEPT
Save the current rules to IPtables file.
# iptables-save > /etc/sysconfig/iptables
Check the opened port 3306 with this command.
# iptables -L -n
If you do not see the port 3306, you may have to restart service iptables and check it again.
# service iptables restart
Login to your mysql service
Now, everything seem okey, you can login to your mysql with below command and create your first database.
# mysql -u root -p'pass'
Replace from the
pass with your root password that you have set up above.
