MariaDB Galera Cluster is a separate product from MariaDB. So, installing it is similar, but not quite the same as installing MariaDB. In particular, the package names for MariaDB's server components are different and there is an extra
galera package that needs to be installed.
For this recipe, we'll assume that we have three servers named
db03, with IP addresses
192.168.1.103, respectively. We'll further assume that they are all running fresh installs of Ubuntu 12.04 LTS.
