Notable changes in this release:

  • If needed, initialization of the initial MySQL database can be performed using the --initialize command:
  • sudo /usr/sbin/mysqld --user=mysql --initialize --log-error=/tmp/mysqld_initialize.log
  • On systemd systems, bootstrapping the first node of the cluster is performed using the following command:
  • sudo /usr/bin/mysqld_bootstrap

Known issues with this release:

  • Mixed-version clusters containing both 5.6 and 5.7 nodes are not supported
  • GTID mode and associated options are not supported and may cause the applier thread to abort;
  • Running the mysqld_upgrade script should be done while the wsrep_provider is not loaded;
  • The --wsrep-replication-bundle option has no effect and may be removed in a future release;
  • InnoDB tablespaces outside of the data directory are not supported, as they may not get copied over during SST;
  • Compilation with DTrace enabled may fail, so -DENABLE_DTRACE=0 may be used to disable DTrace.
  • Packages for RHEL, Debian, and Ubuntu 14.04 will be provided with the GA release.
