Återgå till traditionell replikering från GTID

Om du vill gå tillbaka till gamla :

# Nu ska vi stänga av GTID

Slav 192.168.66.7

mysql> set global gtid_mode='on_permissive';
Query OK, 0 rows affected (0.02 sec)

Mästare 192.168.66.5

mysql> set global gtid_mode='on_permissive';
Query OK, 0 rows affected (0.02 sec)

Slav 192.168.66.7

mysql> set global gtid_mode='off_permissive';
Query OK, 0 rows affected (0.01 sec)

Mästare 192.168.66.5

mysql> set global gtid_mode='off_permissive';
Query OK, 0 rows affected (0.01 sec)

Vid denna tidpunkt kommer replikeringen att bryta på slavsidan. vi kommer att stoppa salvan och ändra masterposition och loggfilen nämner som nedan fel som visas från slavstatus.

Slav 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)

Kontrollera nu att slavstatusreplikeringen fungerar bra, men vi måste fortfarande stoppa GTID:erna.

Nu kommer vi att stänga av gtid-läget =off

Detta kommer att sluta ändra GTID efter att du flyttat tillbaka

Men Exec_Master_Log_Pos:181924 Relay_Log_Space:182357 kommer att förändras hela tiden, denna utgång kan observeras i visa slavstatus.
