Installing MariaDB 10 on CentOS 7 / RHEL 7
Installing MariaDB became very easy on the latest CentOS /RHEL Linux version 7. During initial setup MariaDB has a tick in the graphical setup environment which enables MariaDB and replaces MySQL.
During installation the section
allows enabling a MariaDB server.
If you prefer the command line the installation can be performed with:
shell> yum install mariadb-server
MariaDB is shipped untuned and not protected with MariaDB version 5.5.35. No basic optimizations in the configuration file have been set and the root user has no password. An update will install the version 5.5.37. (The latest version of MariaDB October 2014 is Version 5.5.39).
shell> yum update
It is important to secure the server. MariaDB is shipped with a script to harden the system accordingly using a user dialog. It is highly recommended to use this script before creating and populating the databases.
Install the latest Version 10 is an easy step since MariaDB's repository configuration wizard https://downloads.mariadb.org/mariadb/repositories has now the latest CentOS/RHEL version available.
Before installing 10.0 it is important to perform a backup and remove the existing 5.5 version
shell> yum remove mariadb-server mariadb-libs
Create the repository settings using the link and follow the steps
shell> /etc/init.d/mysql start shell> mysql_upgrade
You are now running the latest 10.0 version! In the next blog we will discuss basic tunings.
