Jika Anda ingin memutar kembali ke yang lama :
# Sekarang, kita akan mematikan GTID
Budak 192.168.66.7
mysql> set global gtid_mode='on_permissive'; Query OK, 0 rows affected (0.02 sec)
Kuasai 192.168.66.5
mysql> set global gtid_mode='on_permissive'; Query OK, 0 rows affected (0.02 sec)
Budak 192.168.66.7
mysql> set global gtid_mode='off_permissive'; Query OK, 0 rows affected (0.01 sec)
Kuasai 192.168.66.5
mysql> set global gtid_mode='off_permissive'; Query OK, 0 rows affected (0.01 sec)
Pada titik ini, replikasi akan pecah di sisi budak. kita akan menghentikan salve dan mengubah posisi master dan penyebutan file log seperti kesalahan di bawah ini yang ditunjukkan dari status budak.
Budak 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)
Sekarang periksa apakah replikasi status slave akan berfungsi dengan baik, tetapi kita masih perlu menghentikan GTID.

Sekarang kita akan mematikan gtid-mode =off
Budak 192.168.66.7
mysql> set global gtid_mode=off; Query OK, 0 rows affected (0.01 sec)
Kuasai 192.168.66.5

Ini akan menghentikan Mengubah GTID setelah Anda kembali

Tetapi Exec_Master_Log_Pos:181924 Relay_Log_Space:182357 akan terus berubah, output ini dapat diamati dalam status show slave.
