For the production environment, it’s recommended that we should use separate server for each Galera Cluster node but sometimes, for the testing purpose we have to setup it on one server with different ports. Here are the steps for how to do that with CentOS 6.8, MariaDB Galera Cluster 10.1.21 and MySQL Sandbox

• Download MariaDB 10.1.21 from this location

Tokutek tests its TokuDB Fractal Tree storage engine with multiple MySQL distributions. We make extensive use of the MySQL Sandbox in our test automation. We tweaked the regular expressions that match binary tarball names in the MySQL Sandbox so that MariaDB releases can be easily loaded by the MySQL Sandbox. These changes can be found in launchpad lp:~prohaska7/mysql-sandbox/mariadb.
