3分鍾解決MySQL 1032主從錯誤
Part1:寫在最前
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
解決方案
Part1:臨時方案
mysql> stop slave; Query OK, 0 rows affected (0.00 sec) mysql> set global sql_slave_skip_counter=1; Query OK, 0 rows affected (0.00 sec) mysql> start slave; Query OK, 0 rows affected (0.00 sec)
Part2:永久方案
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 row affected (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 (0.00 sec) mysql> show slave status\G; *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.1.250 Master_User: mysync Master_Port: 2503306 Connect_Retry: 60 Master_Log_File: mysql-bin.000005 Read_Master_Log_Pos: 3711 Relay_Log_File: HE1-relay-bin.000007 Relay_Log_Pos: 484 Relay_Master_Log_File: mysql-bin.000005 Slave_IO_Running: Yes Slave_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
mysql> update helei set text='ccc' where id=3; Query OK, 1 row affected (0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql> select * from helei; +----+------+ | id | text | +----+------+ | 1 | aa | | 2 | bb | | 3 | ccc | | 4 | ee | | 5 | ff | | 6 | gg | | 7 | hh | +----+------+ 7 rows in set (0.00 sec)HE1從庫報錯

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！這並不能解決該問題，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。
mysql> stop slave; Query OK, 0 rows affected (0.00 sec) mysql> set global sql_slave_skip_counter=1; Query OK, 0 rows affected (0.00 sec) mysql> start slave; Query OK, 0 rows affected (0.00 sec) mysql> select * from helei; +----+--------+ | id | text | +----+--------+ | 1 | aa | | 2 | bb | | 4 | ee | | 5 | ff | | 6 | gg | | 7 | hh | | 8 | helei1 | +----+--------+ 7 rows in set (0.00 sec) mysql> show slave status\G; *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.1.250 Master_User: mysync Master_Port: 2503306 Connect_Retry: 60 Master_Log_File: mysql-bin.000005 Read_Master_Log_Pos: 4119 Relay_Log_File: HE1-relay-bin.000008 Relay_Log_Pos: 283 Relay_Master_Log_File: mysql-bin.000005 Slave_IO_Running: Yes Slave_SQL_Running: Yes
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
