# ==== Purpose ==== # # Reset all replication servers to a clean state: # # - sync all slaves, # - stop all slaves (STOP SLAVE), # - remove all binlogs and relay logs (RESET MASTER and RESET SLAVE), # - start all slaves again (START SLAVE). # # It does not execute CHANGE MASTER, so the replication topology is # kept intact. # # # ==== Usage ==== # # [--let $rpl_only_running_threads= 1] # [--let $rpl_debug= 1] # [--let $slave_timeout= NUMBER] # --source include/rpl_end.inc # # Parameters: # $rpl_only_running_threads # If one or both of the IO and SQL threads is stopped, sync and # stop only the threads that are running. See # include/rpl_sync.inc and include/stop_slave.inc for details. # # $rpl_debug # See include/rpl_init.inc # # $slave_timeout # Set the timeout when waiting for slave threads to stop and # start, respectively. See include/wait_for_slave_param.inc # # Note: # This script will fail if Last_SQL_Error or Last_IO_Error is # nonempty. If you expect an error in the SQL thread, you should # normally do this before you source include/rpl_reset.inc: # # --source include/wait_for_slave_sql_error.inc # --source include/stop_slave_io.inc # RESET SLAVE; --let $include_filename= rpl_reset.inc --source include/begin_include_file.inc if (!$rpl_debug) { --disable_query_log } --source include/rpl_sync.inc if ($rpl_debug) { --echo ---- Stop and reset all servers ---- } --let $_rpl_server= $rpl_server_count while ($_rpl_server) { --let $rpl_connection_name= server_$_rpl_server --source include/rpl_connection.inc # Check if this server is configured to have a master if (`SELECT SUBSTRING('$rpl_master_list', 1 + ($_rpl_server - 1) * $rpl_server_count_length, $rpl_server_count_length) != ''`) { --source include/stop_slave.inc RESET SLAVE; } RESET MASTER; --dec $_rpl_server } --source include/rpl_start_slaves.inc --let $include_filename= rpl_reset.inc --source include/end_include_file.inc
