Deletes all binary log files listed in the index file, resets the binary log index file to be empty, and creates a new binary log file. This statement is intended to be used only when the master is started for the first time.
RESET MASTER removes
all binary log files that are listed
in the index file, leaving only a single, empty binary log
file with a numeric suffix of
whereas the numbering is not reset by
PURGE BINARY LOGS.
RESET MASTER is
not intended to be used while any
replication slaves are running. The behavior of
RESET MASTER when used
while slaves are running is undefined (and thus
LOGS may be safely used while replication slaves
RESET MASTER can prove useful
when you first set up the master and the slave, so that you can
verify the setup as follows:
Start the master and slave, and start replication (see Section 16.1.1, “How to Set Up Replication”).
Execute a few test queries on the master.
Check that the queries were replicated to the slave.
RESET MASTER on the
master to clean up the test queries.
After verifying the setup and getting rid of any unwanted and log files generated by testing, you can start the slave and begin replicating.
