mysql slave狀態如下，發現IO線程為NO狀態，並且報1236錯誤碼

mysql> show slave status\G*************************** 1. row ***************************               Slave_IO_State:                   Master_Host: 10.0.0.20                  Master_User: rep                  Master_Port: 3307                Connect_Retry: 60              Master_Log_File: mysql-bin.000001          Read_Master_Log_Pos: 4               Relay_Log_File: relay-bin.000001                Relay_Log_Pos: 4        Relay_Master_Log_File: mysql-bin.000001             Slave_IO_Running: No            Slave_SQL_Running: Yes              Replicate_Do_DB:           Replicate_Ignore_DB: mysql           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: 4              Relay_Log_Space: 107              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: NULLMaster_SSL_Verify_Server_Cert: No                Last_IO_Errno: 1236                Last_IO_Error: Got fatal error 1236 from master when reading data from binary log: ‘Could not find first log file name in binary log index file‘               Last_SQL_Errno: 0               Last_SQL_Error:   Replicate_Ignore_Server_Ids:              Master_Server_Id: 31 row in set (0.00 sec)

解決辦法

登陸master端做以下操作，並記錄File_zize對應的值107

mysql> reset master;Query OK, 0 rows affected (0.11 sec)mysql> show master logs;+------------------+-----------+| Log_name         | File_size |+------------------+-----------+| mysql-bin.000001 |       107 |+------------------+-----------+1 row in set (0.00 sec)

登陸slave端做一下操作，master_log_pos的值設定為107

mysql> stop slave;Query OK, 0 rows affected (0.00 sec)mysql> change master to master_log_pos=107;Query OK, 0 rows affected (0.11 sec)mysql> start slave;Query OK, 0 rows affected (0.00 sec)mysql> show slave status\G*************************** 1. row ***************************               Slave_IO_State: Waiting for master to send event                  Master_Host: 10.0.0.20                  Master_User: rep                  Master_Port: 3307                Connect_Retry: 60              Master_Log_File: mysql-bin.000001          Read_Master_Log_Pos: 107               Relay_Log_File: relay-bin.000002                Relay_Log_Pos: 253        Relay_Master_Log_File: mysql-bin.000001             Slave_IO_Running: Yes            Slave_SQL_Running: Yes              Replicate_Do_DB:           Replicate_Ignore_DB: mysql           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: 107              Relay_Log_Space: 403              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: 0Master_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: 31 row in set (0.00 sec)

最後主從同步恢複了正常^_^
