"Log in to cluster
If you created a cluster from scratch, you’ll need to get the login credentials (i.e., user name, host address, password) to access one of the nodes with a MySQL client. This can be found by clicking on one of the nodes in Galera Manager, then its Configuration tab. There you’ll find the
DB Address and the
DB Root Password for accessing the database system."
No its not. And without which I can't really do anything else.
