MySql Won't Start Up [SOLVED]

[Henness0666]

I've installed Xampp 1.7.7, Apache runs just fine, but as soon as I click the "Start" button for MySql, it says that it's starting, but then a few seconds latter it goes off again...

This is what the console says

Code: Select all

XAMPP Control Panel Version 2.5 (16. March, 2011)
Windows 6.1 Build 7601 Platform 2 Service Pack 1
Current Directory: c:\xampp
Install(er) Directory: c:\xampp
WARN:This program must be run from your XAMPP root directory.
INFO: Perhaps this program running on a 64 bit plattform please ignore the message above.

At this point I clicked on the "Start" button for MySql

Busy...
MySql started [Port 3306]

At this point the "Stop" button goes back to "Start" and shows MySql is not on but does not say it in the console.

Any advice is helpful. Thanks!

You could use the version 3 control panel found in the xampp installation folder:
xampp-control-3-beta.exe
Right click on it to select to run as an admin for best results.
Stop all XAMPP components and remove the ticks in the Svc check boxes then click on Exit in the older 2.5 version before starting this version 3 control panel.

The latest Control Panel Version3 download is linked in my signature.
Simply extract all the files from the archive to the xampp installation folder and overwrite when asked.
Then right click the exe file to run as administrator and to create a shortcut to the desktop, for example, for easier access.

Make sure that you have exited all other control panel versions before starting this latest version.

This new version has a better log window and is easier to copy and paste in here.

Also in the C:\xampp\mysql\data folder you will find the mysql_error.log file which may give clues and this log file among others is accessible from the latest XCPv3 with the click of a button.

Good luck.

I am now using The beta Control panel v3.0.11, But MySQL still will not start up.

I am still have the same problem can any one help? Here is the error File

Here is the problem.

In the C:\xampp\mysql\data\mysql folder you should see a host.MYD file and it should have a zero size.

If this file is missing then it means that either you have run a clean-up utility that has deleted temp, tmp and zero length files (the xampp folder should be excluded) or they were not extracted when you installed XAMPP.

These files are needed and there are hundreds of zero length files in XAMPP.

You can either uninstall then install again using a different method as outlined in this post:
viewtopic.php?p=179699#p179699
or you can download the zip version and extract all the missing files to their correct locations (this method may be somewhat time consuming).
You could start by extracting from the zip archive, by comparing the data\mysql folder in the zip archive with the same folder in your installation, those zero length files that are missing.

Once you have these zero length files like the host.MYD file replaced then you may be able to start MySQL.

Good luck.

You're welcome and thanks for the feedback.

I will close this topic and mark it solved.

Please feel free to start a new topic if you have any more issues with XAMPP for Windows.

Best wishes.
