MariaDB Galera cluster with xtrabackup-v2 sst

Updated at by

Easier to maintain server and client configuration with one file (/etc/my.cnf) as xtrabackup doesn't understand !include directive. Xtrabackup also reads the datadir from the configuration even if it's the default one. You need MariaDB version >= 10.0.10 for xtrabackup-v2.


Xtrabackup installation

yum install
yum install percona-xtrabackup.x86_64

Mysql user for xtrabackup

GRANT RELOAD, LOCK TABLES, REPLICATION CLIENT, SUPER ON *.* TO xtra@'localhost' identified by 'dunkgonkBlong';
