mysql主从 1061 log同步错误处理

1062和1063错误可以跳过

开发在从库上添加索引导致不同步。

报错如下

Last_Errno: 1061

error 'Duplicate key name 'wolf_cert_no'' on query. Default database: 'wolf'. Query: 'ALTER TABLE cpn_wolf ADD INDEX wolf_cert_no (cert_no)'

库 wolf

表 cpn_wolf

索引 wolf_cert_no (cert_no)

mysql> show index from cpn_wolf;

+------------+------------+--------------------+--------------+-------------+-----------+-------------+----------+--------+------+------------+---------+---------------+

从库上删除

ALTER TABLE `cpn_wolf` DROP INDEX `cert_no`;

从起从库

use mysql

stop slave；

start slave；

mysql> show slave status\G;
