# This file contains wsrep-related mysqld options. It should be included # in the main MySQL configuration file. # # Options that need to be customized: # - wsrep_provider # - wsrep_cluster_address # - wsrep_sst_auth # The rest of defaults should work out of the box. ## ## mysqld options _MANDATORY_ for correct opration of the cluster ## [mysqld] # (This must be substituted by wsrep_format) binlog_format=ROW # Currently only InnoDB storage engine is supported default-storage-engine=innodb # to avoid issues with 'bulk mode inserts' using autoinc innodb_autoinc_lock_mode=2 # Override bind-address # In some systems bind-address defaults to 127.0.0.1, and with mysqldump SST # it will have (most likely) disastrous consequences on donor node bind-address=0.0.0.0 ## ## WSREP options ## # Enable wsrep wsrep_on=1 # Full path to wsrep provider library or 'none' wsrep_provider=none # Provider specific configuration options #wsrep_provider_options= # Logical cluster name.
