解決mysql 1062 主從錯誤
阿新 • • 發佈：2019-01-08
1062錯誤----主鍵衝突，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：
從庫操作
mysql> stop slave; Query OK, 0 rowsaffected (0.26 sec) mysql> set global sql_slave_skip_counter=1; Query OK, 0 rowsaffected (0.30 sec) mysql> start slave; Query OK, 0 rowsaffected (0.04 sec) mysql> show slavestatus\G ***************************1. row *************************** Slave_IO_State: Waiting formaster 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: 2909 Relay_Log_File:HE1-relay-bin.000006 Relay_Log_Pos: 283 Relay_Master_Log_File: mysql-bin.000005 Slave_IO_Running: <strong>Yes</strong> Slave_SQL_Running: <strong>Yes</strong> Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 0 Last_Error: Skip_Counter: 0 Exec_Master_Log_Pos: 2909 Relay_Log_Space: 1214 Until_Condition: None Until_Log_File: Until_Log_Pos: 0 Master_SSL_Allowed: No Master_SSL_CA_File: Master_SSL_CA_Path: Master_SSL_Cert: Master_SSL_Cipher: Master_SSL_Key: Seconds_Behind_Master: 0 Master_SSL_Verify_Server_Cert:No Last_IO_Errno: 0 Last_IO_Error: Last_SQL_Errno: 0 Last_SQL_Error: Replicate_Ignore_Server_Ids: Master_Server_Id: 2503306 Master_UUID:f7c96432-f665-11e5-943f-000c2967a454 Master_Info_File:/data/mysql/master.info SQL_Delay: 0 SQL_Remaining_Delay: NULL Slave_SQL_Running_State: Slave has readall relay log; waiting for the slave I/O thread to update it Master_Retry_Count: 86400 Master_Bind: Last_IO_Error_Timestamp: Last_SQL_Error_Timestamp: Master_SSL_Crl: Master_SSL_Crlpath: Retrieved_Gtid_Set: Executed_Gtid_Set: Auto_Position: 0 1 row in set (0.00sec)
故障模擬
從庫如果誤插入
mysql> insertinto helei(text) values('iii'); Query OK, 1 rowaffected (0.28 sec) mysql> select *from helei; +----+------+ | id | text | +----+------+ | 1 | aa | | 2 | bb | | 3 | cc | | 4 | ee | | 5 | ff | | 6 | gg | | 7 | hh | | 8 | iii | +----+------+ 8 rows in set (0.00sec) mysql> show slavestatus\G ***************************1. row *************************** Slave_IO_State: Waiting formaster 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: 2509 Relay_Log_File:HE1-relay-bin.000005 Relay_Log_Pos: 480 Relay_Master_Log_File: mysql-bin.000005 Slave_IO_Running: <strong>Yes</strong> Slave_SQL_Running: <strong>Yes</strong>
這時候從庫是正常的，但由於從庫私自插入資料，已經和主庫不一致，如果這時主庫也插入相同的資料
主庫此時沒有8,iii這條記錄
