Error: MySQL shutdown unexpectedly.

[grifon]

Hi,

I have never worked with XAMPP, so I am sorry for my maybe stupid questions. I have downloaded the programme and I wanted to start MySQL, but an error message appeared, which said that the port: 3306 would be already taken. I have restarted the programme and un- and reinstalled the MySQL Service. Now another error message appears:

I am sorry, if this problem has already been solved here, but I have not found it.

Please help me, I do not have an idea what it could be.

If you can reproduce the "3306 is taken". Run Command Prompt -> Type in: NetStat -o
This will show you a list of services using that port associated with a PID.
Start Task Manager -> Go to Services Tab and search for the same PID and this is what is using that port.
Stop the service and make sure it is not set to start up automatically otherwise you will encounter this issue again.
This should allow you to start MySQL without issue.

Make sure the MySQL service is uninstalled first ->
Re-Download XAMPP and copy over any missing files. Make sure this file exists: "D:\xampp\mysql\data\ib_logfile1"
-2015-02-28 15:07:06 7676 [ERROR] InnoDB: Cannot create D:\xampp\mysql\data\ib_logfile1

Replace this file: D:\xampp\mysql\data\ibdata1
2015-02-28 15:07:22 6052 [ERROR] InnoDB: space header page consists of zero bytes in data file D:\xampp\mysql\data\ibdata1

I would suggest you download a fresh copy of xampp (same version) and replace the mysql folder to start fresh.
I would highly recommend downloading the latest version of XAMPP and getting a fresh start if there is not much developed.
