# ==== 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_skip_sync
|
|
# By default, all slaves are synced using rpl_sync.inc. Set this
|
|
# option to 1 to disable this behavior (note that you must
|
|
# manually sync all servers in this case). Normally you want to
|
|
# sync, but you need to disable sync if you use multi-source.
|
|
#
|
|
# $rpl_debug
|
|
# See include/rpl_init.inc
|
|
#
|
|
# $rpl_no_start_slave
|
|
# Don't execute START SLAVE.
|
|
#
|
|
# $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
|
|
|
|
