EXAMPLES

systemd

When MariaDB Server (mariadbd) is started via systemd, the galera_new_cluster utility can be used:

$ sudo galera_new_cluster

When the galera_new_cluster utility is executed, it starts the mariadb.service systemd unit with the --wsrep-new-cluster command-line option added to the mariadbd command.

Since this command starts the mariadb.service systemd unit, the service should be stopped prior to running this command.

Set on the Command-line

When MariaDB Server (mariadbd) is started via the command-line, the --wsrep-new-cluster command-line option can be specified:

$ mariadbd .. --wsrep-new-cluster ..

Set in a Configuration File

The --wsrep-new-cluster command-line option can be specified in a configuration file:

[mariadb]
wsrep-new-cluster

When the --wsrep-new-cluster command-line option is specified in a configuration file that the node reads during startup, the node forms a new cluster. MariaDB recommends removing the option from the configuration file immediately for safety reasons. If the option is left in the configuration file, the node will form a new cluster every time it is restarted, even if the other cluster nodes are online.
