Relay log read failure的处理

以下是代码片段: mysql> show slave status\G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: 192.168.10.118 Master_User: repl_wu Master_Port: 3306 Connect_Retry: 30 Master_Log_File: mysql-bin.005121 Read_Master_Log_Pos: 64337286 Relay_Log_File: relay-bin.003995 Relay_Log_Pos: 18446697137031827760 Relay_Master_Log_File: mysql-bin.005121 Slave_IO_Running: Yes Slave_SQL_Running: No Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 1594 Last_Error: Relay log read failure: Could not parse relay log event entry. The possible reasons are: the master’s binary log is corrupted (you can check this by running ’mysqlbinlog’ on the binary log), the slave’s relay log is corrupted (you can check this by running ’mysqlbinlog’ on the relay log), a network problem, or a bug in the master’s or slave’s MySQL code. If you want to check the master’s binary log or slave’s relay log, you will be able to know their names by issuing ’SHOW SLAVE STATUS’ on this slave.

从上面可以看到是中继日值或是Master上的日值出问题了。
首先如果是中继日值坏掉,那只需要找到同步的时间点,然后重新同步,这样就可以有新的中继日值了。如果Master上的日值坏了就麻烦了。
从经验来看,这是中继日值出问题了。处理方法:
需要找到同步的点。
日值为:Master_Log_File: mysql-bin.005121,Relay_Master_Log_File: mysql-bin.005121以Relay_Master_Log_File为准,Master_Log_File为参考。
日值执行时间点:
以下是代码片段: Exec_Master_Log_Pos: 4 |
那么现在就可以:
以下是代码片段:
mysql>stop slave;
mysql>change master to Master_Log_File=’mysql-bin.005121’, Master_Log_Pos=4;
mysql>start slave;
mysql>show slave status\G;
进行确认。
建议:
在使用MySQL-5.1.36以下的版本的同学,请尽快升级到MySQL-5.1.40 & MySQL-5.1.37sp1
