——解决方案——————–
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
——解决方案——————–
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;

、？
？？？？？？？？？？？？？？？？？？？？？？？？
——解决方案——————–
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。
——解决方案——————–
1. mysql> stop slave;
2. mysql> set global sql_slave_skip_counter=1;
3. mysql> start slave;
