+It is aweome! I could test galera without edit mysql files. But I have a doubt, if I stop the node1, insert some records and then start node1 again, we will have a desync for this node. Do you know how to solve this?

+You need to restart node1 without --wsrep-new-cluster or it will create a new standalone single node cluster.
