binlog/relay_log的清理

CHANGE MASTER TO
changes the parameters that the slave server uses for connecting to the master server, for reading the master binary log, and reading the slave relay log. It also updates the contents of the master.info
andrelay-log.info
files. To use CHANGE MASTER TO
, the slave replication threads must be stopped (use STOP SLAVE
if necessary).
CHANGE MASTER TO
deletes all relay log files and starts a new one, unless you specify RELAY_LOG_FILE
orRELAY_LOG_POS
. In that case, relay log files are kept; the relay_log_purge
global variable is set silently to 0.
