Getting MariaDB Up and Running

3 min read

RHEL 7 comes with MariaDB by default. Don’t get surprised if you don’t see MySQL server specific packages being displayed through YUM search utility. While most of your applications still uses MySQL in older generation of RHEL 6 or CentOS 6, migrating to newer RHEL 7 or CentOS 7 might require MariaDB configuration. This post will help you get started with MariaDB Up and Running.

Installing MariaDB:

[root@collabnix ~]# yum install mariadb mariadb-server
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: centos-hcm.viettelidc.com.vn
* epel: epel.mirror.net.in
* extras: centos-hn.viettelidc.com.vn
* updates: centos-hcm.viettelidc.com.vn
