Vraťte se k tradiční replikaci z GTID

Pokud se chcete vrátit ke starému :

# Nyní vypneme GTID

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)

V tomto okamžiku se replikace přeruší na podřízené straně. zastavíme salve a změníme hlavní pozici a logovací soubor jako níže uvedenou chybu ze stavu podřízeného.

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)

Nyní zkontrolujte, že replikace stavu slave bude fungovat dobře, ale stále budeme muset zastavit GTID.

Tím přestanete měnit GTID poté, co se přesunete zpět

Ale Exec_Master_Log_Pos:181924 Relay_Log_Space:182357 se bude neustále měnit, tento výstup lze sledovat ve stavu show slave.
