Usage: ${0}

The script galera_new_cluster is used to bootstrap new Galera Cluster,
    when all the nodes are down. Run galera_new_cluster on the first node only.
    On the remaining nodes simply run 'service  start'.

For more information on Galera Cluster configuration and usage see:
    https://mariadb.com/docs/galera-cluster/galera-cluster-quickstart-guides/mariadb-galera-cluster-guide
