1062錯誤----主鍵沖突,出現這種情況就是從庫出現插入操作,主庫又重新來了一遍,iothread沒問題,sqlthread出錯
解決方案:
mysql> stop slave;
mysql> set global sql_slave_skip_counter=1;
mysql> start slave;
故障模擬:
從庫如果誤插入
mysql> insert into helei(text) values('iii');
Query OK, 1 row affected (0.28 sec)
mysql> select * from helei;
+----+------+
| id | text |

| 2 | bb
| 3 | cc
| 4 | ee
| 5 | ff
| 6 | gg
| 7 | hh
| 8 | iii
+----+------+
8 rows in set (0.00
mysql> show slave

這時候從庫是正常的,但由於從庫私自插入數據,已經和主庫不一致,如果這時主庫也插入相同的數據
主庫此時沒有8,iii這條記錄

出現這樣的問題,先停從庫,set跳過這條事務
HE1從庫操作
mysql> stop slave;
Query OK, 0 rows
affected (0.26 sec)
mysql> set global sql_slave_skip_counter=1;(這裏寫10也是一樣的,最好不用這種方法,用pt-slave-restart,無需手動stop/start slave)
Query OK, 0 rows
affected (0.30 sec)
mysql> start slave;
Query OK, 0 rows
affected (0.04 sec)
mysql> show slave status\G
