sql_error后重启mysql复制

Question

我有两台mysql服务器，一台主一台从。

有人继续到从站并创建了一个表，然后又继续到主站并创建了同一张表。当然这个DDL语句被复制到了slave，导致出错，导致复制在出错点停止。

在从属服务器上删除表或在该语句之后开始复制后，我应该如何重新启动复制过程？

显示从站状态输出：

Answer 1

您可以使用以下命令（在 mysql 提示符下）：

mysql> STOP SLAVE;
mysql> SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;
mysql> START SLAVE;
mysql> SHOW SLAVE STATUS;

该值1表示要跳过的语句数。您可以重复执行此操作，直到修复复制。你可以看到这个页面。
