1067 error on attempt to start MySQL

Question

I\'ve installed MySQL on Windows 7. When I\'m trying to start MySQL service I\'m getting error 1067: The process terminated unexpectedly. Log message:

Answer 1

The solution to the problem for me was looking in my install directory, finding the /data folder, and copying it's content to the data folder that was specified in my .ini/.cnf configuration file.

Answer 2

when looked at mysql log (.err file under data folder), i could see the following

21:41:47 UTC - mysqld got exception 0xc0000005 ; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. Attempting to collect some information that could help diagnose the problem. As this is a crash and something is definitely wrong, the information collection process might fail.

I realized i was starting the service while i plugged usb. To be honest, the problem was resolved after i restarted my machine followed by restarting the service. In addition i removed ib_logfile0 and ib_logfile1 files before my restart. Though the event logger indicated "InnoDB: Your database may be corrupt or you may have copied the InnoDB tablespace but not the InnoDB log files. Please refer to http://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html for information

about forcing recovery.For more information, see Help and Support Center at http://www.mysql.com", i do not think so because i never changed any configurations.

Answer 3

I run MariaDB (MySQL compatible) on two machines locally. I'm not sure what prompted the error and nothing I tried worked. So I stopped the service, deleted everything in MariaDB's directory (except the data directory) and copied the files from my secondary machine and everything is working well enough as far as I can tell.

For a live server it'd be a bit different and a super-guru might be able to add an insight comment (e.g. something outside of the data directory might have something to do with preventing data corruption or indexes in example?). I would just stop the service and copy the entire directory once every month or so and then start the service again.

Answer 4

In my case, I had chosen a custom path for my log-files in the MySQL installer. I had put the log-files in my user-folder C:\Users\%MY_USERACCOUNT%\Documents\mysql-logs, and by default, NETWORK SERVICE (or any other non-administrator useraccount in Windows) does not have access to a user's folder.

I fixed this by changing security options for the log-folder, giving modify rights read/write/modify rights to NETWORK SERVICE.

Answer 5

I have mysql data folder replaced by a windows directory junction. I suspect ib_logfile0/1 and/or ibdata1 is corrupted.

Just try to delete those files and computername.err. Then restart mysql service. That's what I did, with success.

Copying ibdata1 files, after a full reinstallation of mysql, to the junction dir and replacing dir by the junction, restarting mysql, was not enough.

You have to let mysql rebuild those files.

Answer 6

I just encountered a similar issue and I found that it is a permission problem. When I copy the database "data", I have to add the permission for "NETWORK SERVICE"
