"Error 1067: The process terminated unexpectedly" when trying to start MySQL

Question

I'm using Windows 7 and running XAMPP MySQL SVC service. I'm seeing the following error:

Windows could not start the Mysql service on Local Computer.

Error 1067: The process terminated unexpectedly.

What does this mean, and how can I fix it?

Answer 1

You need to:

1. stop the MySQL service:
2. Open mysql path\data
3. Remove both ib_logfile0 and ib_logfile1.
4. Restart the service

Answer 2

Examine error log (start eventvwr.msc). MySQL typically writes something to the Application log.

In very rare cases it does not write anything (I'm only aware of one particular bug http://bugs.mysql.com/bug.php?id=56821, where services did not work at all). There is also error log file, normally named .err in the data directory that has the same info as written to windows error log.

Answer 3

I had the same problem. I am using mysql 5.6.11. To solve this problem I had to change my-default.ini file in mysql-5.6.11-win32 folder So I just pasted the following lines under line [mysqld]

basedir="D:\mysql-5.6.11-win32\"
datadir="D:\mysql-5.6.11-win32\data\"
port=3306
server-id=1
bind-address=127.0.0.1

Options basedir and datadir need to be modified for mysql location.

Answer 4

Don't forget to check

innodb_data_home_dir = <your_directory_location>
innodb_log_group_home_dir = <your_directory_location>

on my.ini files. Wrong set value for these two variable make mysql process terminated and produce error 1067. Also check eventvwr.msc and mysql_error.log for detail error.

Answer 5

I had the same problem but I was confused with @Vladislav's answer and couldn't seem to find the solution from that. Of course, my problem may not be exactly the same as I encountered the problem when trying to upgrade XAMPP, but it also gave the same Error 1067 message.

With further search I found this:

https://serverfault.com/questions/214435/error-1067-the-process-terminated-unexpectedly-when-trying-to-install-mysql-on

The answer from that is straightforward, that is, to completely clean up the folder, which doesn't always happen. As in regards to XAMPP, I guess I backed up the necessary files first (data folder from mysql folder and the htdocs folder). Uninstall XAMPP. Check the xampp folder for any content that remains and delete everything. You may want to reboot afterwards, just in case. Then reinstall XAMPP. Copy the backed-up folders back to their respective places, and hopefully, mySql will work again in XAMPP.

This should solve the issue.
