I/o Error Reading The Header From The Binary Log Errno=-1
to start mysql ,i got the following error : 121010 13:57:47 [ERROR] I/O error reading the header from the binary log, errno=175, io cache code=0 121010 13:57:47 [ERROR] I/O error reading the header from the binary log 121010 13:57:47 [ERROR] Can't init tc log 121010 13:57:47 [ERROR] Aborting This means that you have a problem related to binary log files , the binary logs are broken, or at least the last one is. They are usually located in /var/logs/mysql/ and you should not start copying over some old logs with the new name because that would just not make it right, so the solution is, read your logs and see which *.bin file is corrupted delete it open /var/log/mysql/mysql-bin.index and delete the line with the bin file on it. Restart mysql

If this hex value is not in the header of the binlog, it is definitely corrupt. BINLOG FILESIZE For any binlog position, there is a a corresponding filesize. In other words, whenever mysqld records a SQL command, it does the following: retrieves the current filesize to the statement size calculates the size of the statement it will record (comments included) Comment contains filesize + statement size This sum is designated the binlog position Statement is appended to the binlog Comments are appended to the binlog In light of this, you can run SHOW MASTER STATUS; and get something like this: mysql> show master status; +------------------+-----------+--------------+------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +------------------+-----------+--------------+------------------+ | mysql-bin.000109 | 569025336 | | | +------------------+-----------+--------------+------------------+ 1 row in set (0.00 sec) mysql> If there are no writes going on (low writes,high reads), you
