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)

从库上删除  
ALTER TABLE \`cpn\_wolf\` DROP INDEX \`cert\_no\`;  
  
  
从起从库  
use mysql  
stop slave；  
start slave；
