Fun with MariaDB Galera cluster
Written by Dominik Joe Pantůček on 2016-04-21
Striving for high-availability of some software systems requires ensuring their individual components are reliable and usually redundant. A typical example of such component is a SQL database - MariaDB being the case we had to handle this time.
We decided to go for MariaDB Galera cluster on CentOS and I would like to write about our experience here. We have chosen active-active (master-master) design with two nodes called nodeA and nodeB having IP addresses 192.168.0.1 and 192.168.0.2 respectively.
