MySQL don't start

[felixinx]

Hi,

I recently update my xampp to the latest version, and, MySQL don't start. Here you can see the log error;

Code: Select all

Note that I copy the

Code: Select all

C:\xampp_oldbkp\mysql\data

to

Code: Select all

C:\xampp\mysql\data

for duplicate the database. I think this is the error but i don't know how to do it because my oldmysql don't start (and my new too now). Tank you!

How did you "update" Xampp? There is neither an update procedure, nor an update installation. If you simply installed a new version over the old, you destroyed all documents and all databases.

This is how I upgarde from 5.5 to 5.6.3 (latest).

1. Rename C:\xampp to C:\xampp_oldbkp
2. Install new version with insatller to C:\xampp
3. Move all the file and folder from C:\xampp_old_bkp\htdocs to C:\xampp\htdocs (works great!)
4. Move all the file and folder from C:\xampp-old_bkp\mysql\data to C:\xampp\mysql\data

This is all my steps and the PHP and APACHE are working great.

EDIT: I reinstall the mysql folder file by deafult and copied only my database. the problem was corrupted file with the older version and new one.

Problem solved!

Tank you.
