Replica’s IP address was changed so it went out of sync and can’t re-sync automatically as bin log file no longer exists on the source. I’ve been reading other posts with similar issues but I couldn’t find a solution.
I want to avoid recreating replica. Is there a way we could start syncing replica from the most recent bin log files on source? Can I run following command, will it work?
# stop slave
mysql> stop slave;
# make slave forget its replication position in the master's binary log
mysql> reset slave;
# change slave to start reading from new/most recent position
mysql> change master to master_log_file='mysql-bin.000084', master_log_pos=0;
# start slave
mysql> start slave;
Replica
mysql> show replica status\G
