1032錯誤----現在生產庫中好多數據，在從庫誤刪了，生產庫更新后找不到了，現在主從不同步了，再跳過錯誤也沒用，因為沒這條，再更新還會報錯

臨時解決方案

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)

永久解決方案：

end_log_pos 有了它，根據pos值，直接就能找到，找到delete那條數據，反做（變成insert）

故障模擬：

HE1從庫誤刪

mysql> delete from helei where id=3; Query OK, 1 rowaffected (0.29 sec)mysql> select * from helei; +----+------+ | id | text | +----+------+ | 1 | aa | | 2 | bb | | 4 | ee | | 5 | ff | | 6 | gg | | 7 | hh | +----+------+ 6 rows in set (0.00sec)mysql> show slavestatus\G; ***************************1. row ***************************Slave_IO_State: Waiting formaster to send eventMaster_Host: 192.168.1.250Master_User: mysyncMaster_Port: 2503306Connect_Retry: 60Master_Log_File: mysql-bin.000005Read_Master_Log_Pos: 3711Relay_Log_File:HE1-relay-bin.000007Relay_Log_Pos: 484Relay_Master_Log_File: mysql-bin.000005Slave_IO_Running: YesSlave_SQL_Running: Yes

此時從庫狀態是正常的，但一旦主庫對該條記錄進行操作

HE3主庫更新從庫剛剛誤刪的數據

此時主從又不同步了,如果還去執行跳過錯誤操作，主從恢復同步，而且狀態均為yes，但！這并不能解決該問題，如果主庫又更新該條記錄，那么還是會報相同錯誤，而且pos號還會變，這就導致了恢復時你不知道前一條的pos號，導致丟失數據。

這里雖然通過跳過錯誤達到恢復主從同步，但如果主庫又對該條記錄更新
