Question

我刚刚通过我的提供者的API自动创建了一个mysql 5.6主/从关系，这意味着我没有root用户。所以在设置了slave之后，我启用了slave上的root用户，这当然打破了复制。我需要跳过那个GTID，但我很难理解这个问题。

STOP SLAVE;
SET GTID_NEXT="5b182ac6-8a79-11e4-8f28-001851cf5e10:10";
BEGIN; COMMIT;
SET GTID_NEXT="AUTOMATIC";
START SLAVE

导致相同的错误。什么是正确的GTID选择？

Answer 1

查看已执行的GTID集。

Executed_Gtid_Set: 08bc8aa0-8a7a-11e4-8f2d-001851502460:1-41,
                   5b182ac6-8a79-11e4-8f28-001851cf5e10:9-69

08bc8aa0-8a7a-11e4-8f2d-001851502460可能是你的奴隶，你的主人是

Master_UUID: 5b182ac6-8a79-11e4-8f28-001851cf5e10

你可以看到上面的几行。因此，从主人那里执行交易9-69。所以下一个GTID是70。

另请注意，您应该使用Auto_Position: 1语句设置CHANGE MASTER TO。阅读更多相关信息here。
