1 row in set (0.00 sec)

您的从服务器数据和主服务器不一致,从服务器没有这个索引

‘ALTER TABLE `company_position` DROP INDEX `user_id_2

主服务器上看看这个语句,删除索引可以跳过去的

SHOW BINLOG EVENTS IN ‘mysql-bin.000048’ FROM 137205272;

从服务器上执行，就可以跳过一个语句

SET GLOBAL sql_slave_skip_counter = 1;

参见

http://dev.mysql.com/doc/refman/5.1/en/set-global-sql-slave-skip-counter.html




这个位置，上面看错了

主服务器上看看这个语句,删除索引可以跳过去的

SHOW BINLOG EVENTS IN ‘mysql-bin.000037’ FROM 943949;

、？

？？？？？？？？？？？？？？？？？？？？？？？？




意思就是说你从机上没有那个INDEX，但是现在要执行，所以就报错了。




1. mysql> stop slave; 

2. mysql> set global sql_slave_skip_counter=1;

3. mysql> start slave;
