If you want to roll back to old :
# Now, we are going to turn GTID’s off
Slave 192.168.66.7
mysql> set global gtid_mode='on_permissive'; Query OK, 0 rows affected (0.02 sec)
Master 192.168.66.5
mysql> set global gtid_mode='on_permissive'; Query OK, 0 rows affected (0.02 sec)
Slave 192.168.66.7
mysql> set global gtid_mode='off_permissive'; Query OK, 0 rows affected (0.01 sec)
Master 192.168.66.5
mysql> set global gtid_mode='off_permissive'; Query OK, 0 rows affected (0.01 sec)
At this point, the replication will break at slave side. we will stop the salve and change master position and logfile mention as below error shown from slave status.
Slave 192.168.66.7
mysql> show slave status\G *************************** 1. row *************************** Last_IO_Errno: 13114 Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: 'Cannot replicate anonymous transaction when AUTO_POSITION = 1, at file ./mysql-bin.000007, position 196.; the first event '' at 4, the last event read from './mysql-bin.000007' at 275, the last byte read from './mysql-bin.000007' at 275.' mysql> stop slave; Query OK, 0 rows affected (0.00 sec) mysql> change master to master_log_file='mysql-bin.000007', master_log_pos=196,master_auto_position=0; Query OK, 0 rows affected (0.02 sec) mysql> start slave; Query OK, 0 rows affected (0.00 sec)
Now check the slave status replication will work fine, but we will still need to stop the GTID’s.

Now we will turn off the gtid-mode =off
Slave 192.168.66.7
mysql> set global gtid_mode=off; Query OK, 0 rows affected (0.01 sec)
Master 192.168.66.5
mysql> set global gtid_mode=off; Query OK, 0 rows affected (0.01 sec)
This will stop Changing the GTID after you move back
Executed_Gtid_Set: 95358015-b479-11ea-ab4c-080027267f61:1-10110
But Exec_Master_Log_Pos: 181924 Relay_Log_Space: 182357 will keep changing, this output can be observed in show slave status.
