1032错误----现在生产库中好多数据，在从库误删了，生产库更新后找不到了，现在主从不同步了，再跳过错误也没用，因为没这条，再更新还会报错

临时解决方案

mysql> stop slave;

Query OK, 0 rowsaffected (0.00 sec)

mysql> set global sql_slave_skip_counter=1;

ERROR 1193 (HY000):Unknown system variable 's_slave_skip_counter'

mysql> set global sql_slave_skip_counter=1;

Query OK, 0 rowsaffected (0.00 sec)

mysql> start slave;

Query OK, 0 rowsaffected (0.00 sec)

永久解决方案：

end_log_pos有了它，根据pos值，直接就能找到，找到delete那条数据，反做(变成insert)

故障模拟：

HE1从库误删

mysql> delete from helei where id=3;

Query OK, 1 rowaffected (0.29 sec)

mysql> select * from helei;

6 rows in set (0.00sec)

mysql> show slavestatus\G;

此时从库状态是正常的，但一旦主库对该条记录进行操作

此时主从又不同步了,如果还去执行跳过错误操作，主从恢复同步，而且状态均为yes，但！这并不能解决该问题，如果主库又更新该条记录，那么还是会报相同错误，而且pos号还会变，这就导致了恢复时你不知道前一条的pos号，导致丢失数据。
