If your data is important make sure you are on a RAID1 or RAID5 setup (so that if one hard drive dies, your server will continue running normally). 'Any recommendations on strategies for reducing likelihood of corruption?'Ĭorruption can typically be traced back to either hardware failure or high load. I strongly discourage using InnoDB databases on a shared hosting platform. If you're running on a shared-server hosting platform, you can still export/import all data by using phpmyadmin (should be provided by your host).

Step 1: Add this line to your /etc/my.cnf configuration file: Once you have corrupt InnoDB tables that are preventing your database from starting, you should follow this five step process: You lose data consistency and will often break replication.

There are tricks to update InnoDB's internal log counter so that it skips the queries causing the crash, but in our experience this is not a good idea. This is one reason why you should always run a master/master setup when using InnoDB - have a redundant master if one fails to start.īefore you go any further, review MySQL log file and confirm the database is not starting due to InnoDB corruption. You can try to restart the database again and again, but if the repair process fails - the database will refuse to start.

MySQL will exit with an error message and your entire database will be offline. Unfortunately if InnoDB fails to repair itself, the -entire- database will not start. In most cases it will succeed and the entire process is transparent. If the database crashes, InnoDB will attempt to fix everything by running the log file from the last timestamp. InnoDB's internal recovery mechanism is pretty good. Transactional, reliable and unlike MyISAM, InnoDB supports concurrent writes into the same table. If you're getting bombarded with queries and you need to be able to connect to the database to make some table changes, set a different port number in your /etc/my.cnf file, start the database, make any changes, then update the port back to normal (master-port = 3306) and restart. Try restarting the database and see if that helps.
