1 row in set (0.00 sec)
第五步 – 检查Master的数据是否都同步到Slave上了，Empty表示都同步了
- 匿名复制，即所有非gtid的复制，即基于日志的复制;
- 如果结果非空，要等到结果为空才能继续操作;
mysql> show status like 'ongoing_anonymouse_transaction_count';
Empty set (0.00 sec)
第六步
mysql> set @@global.gtid_mode=on;
Query OK, 0 rows affected (0.02 sec)
第七步
mysql> stop slave;
Query OK, 0 rows affected (0.01 sec)
第八步
mysql> change master to master_auto_position=1;
Query OK, 0 rows affected (0.01 sec)
第九步
mysql> start slave;
Query OK, 0 rows affected (0.01 sec)
第十步
- 当主从间发生同步后，Retrieved_Gtid_Set & Executed_Gtid_Set才有值；
mysql> show slave status\G;
