Hi Config follows: # 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 # This is a must for paralell applying innodb_locks_unsafe_for_binlog=1 #Try to fix futex loop innodb_thread_concurrency = 32 # Query Cache is not supported with wsrep query_cache_size=0 query_cache_type=0 # 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=10.0.176.3 port=3307 ## ## WSREP options ## # Full path to wsrep provider library or 'none' wsrep_provider=/usr/lib/galera/libgalera_smm.so # Provider specific configuration options # See http://www.codership.com/wiki/doku.php?id=faq wsrep_provider_options="pc.ignore_sb = no;ist.recv_addr=10.0.176.3;gmcast.listen_addr=tcp://10.0.176.3:4567" # Logical cluster name.
