1.登录从库 mysql -u root -p

2.输入命令查看状态

SHOW SLAVE STATUS\G;

 3.找到对应的错误数据位置

4.查看日志命令

/usr/local/mysql/bin/mysqlbinlog --no-defaults --base64-output=decode-rows -v /mysql/mysqldb/binlog.000552 |grep  -A 20 "4512"

5.具体的错误

6.再从库中，对数据进行相关的操作。

7. 重启 START SLAVE;

8.再次查看状态 SHOW SLAVE STATUS\G。如果没有错误恢复正常，有错误，继续处理。

9.正常状态
