deleted from the folder. This happens when the slave has been disconnected failed to open the relay log from the master for quite a long time already and has not replicated anything. A simple way to fix this could not initialize master info structure is to flush the logs, but make sure the slave is stopped before using this command… FLUSH LOGS; Bring in a fresh copy of the database from the master-server and update

the slave-server database. THIS IS IMPORTANT! Since if you don't update the slave database, you will not have the data from the time you were disconnected until you reset the relay logs. So UPDATE YOUR SLAVE WITH THE LATEST DATABASE FROM THE MASTER! Now when the logs are flushed,all the relay-bin logs will be deleted when the slave is started again. Usually, this fixes
Error Reading Master Configuration
the problem, but when you start the slave and the failed relay log error is still there, now you have to do some more desperate measures… reset the slave. This is what I had to do to fully restore my MySQL slave server. Reseting the slaves restores all the settings to default… password, username, relay-log, port, table to replicate, etc… So better to have a copy of your settings first before actually do a slave reset. When your ready to rest the slave, do the command… RESET SLAVE; after which you should restore all your setting with a command something like… CHANGE MASTER TO MASTER_HOST=..... now start your server with… SLAVE START; check your slave server with… SHOW SLAVE STATUS\G look for … Slave_IO_Running: Yes
Slave_SQL_Running: Yes both should be YES, if not, check your syslog if there are other errors encountered. I'll leave this until here since this is what I encountered and I was able to fix it. Edit 5/14/11: There is a possible change that after executing the CHANGE MASTER command that you'll receive this error below… ERROR 1201 (HY000): Could not initialize master info

Under normal circumstances it performs as intended, but it breaks if it encounters a hard reboot (I pull the http://serverfault.com/questions/715849/hard-reboot-causes-mysql-replication-to-break power cable). Setup The setup consists of two servers, server-1 and server-2. The replication setup is a circular replication. Both servers are slaves replicating from the other host as if it were the master. Software Red Hat 6.5 MySQL 5.1.73-3 MySQL-libs 5.1.73-3 MySQL-server 5.1.73-3 Redundancy configuration The replication configuration is as follows for server-1, and is mirrored for server-2: GRANT REPLICATION SLAVE ON *.* TO 'replicant'; FLUSH TABLES WITH READ LOCK;" #Use "SHOW MASTER STATUS \G;" to determine log position and log file UNLOCK TABLES; # set status on slave server using the values retieved earlier CHANGE MASTER TO MASTER_HOST='server-2', MASTER_USER='replicant', MASTER_LOG_FILE='[log file]', MASTER_LOG_POS=[log pos];" START SLAVE; Error information This information is retrieved when the server-2 has encountered a hard reboot and the replication is broken. server-1 slave status *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: server-2 Master_User: replicant Master_Port: 3306 Connect_Retry: 60 Master_Log_File: bin.000004 Read_Master_Log_Pos: 37550 Relay_Log_File: relay.000427 Relay_Log_Pos: 245 Relay_Master_Log_File: bin.000004 Slave_IO_Running: Yes Slave_SQL_Running: Yes 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: 37550 Relay_Log_Space: 529 Until_Condition: None Until_Log_File: Un
