I don't see an error in this log!?
Maybe you should try again to describe your problem more precisely.

my squl doesnt start.. i didn´t do anything

[Altrea]

Please try to start MariaDB that way and report back, what you get as response:

• Open your XAMPP control panel
• click the Shell Button. If you get asked to create the file for the first time, confirm this.
• Execute the following command
  

  Code: Select all

  mysqld --defaults-file=mysql\bin\my.ini --standalone --console

[Mada]

does it delete my data? i allready created a lot on wordpress..
will it delete?
i have no backup

[Altrea]

No, if you strictly follow these instructions, these files do not contain any important database data.

Please try the following workaround:

Open your folder "\xampp\mysql\data"
Delete all files beginning with "master-"
Delete all files beginning with "mysql_relay-bin-"
Delete all files beginning with "relay-log-"
Delete all files beginning with "ib_logfile"
Delete all files beginning with "aria_log."

Now try to start MariaDB again as regular.

[Mada]

ih, it still says that has an error

[Altrea]

Ok, so what files are left in your \xampp\mysql\data\ folder?

[kubegus]

Hi!

I have the same problem. I tried your advices, but the problem still.

I can run Apache, but not MySQL

After delete the files you indicated, I got:

ibdata1
multi-master.info
my.ini
mysql_error.log



cheers!

[Altrea]

Delete the file multi-master.info

What is the output of running mysqld in console like described earlier after this?

[kubegus]

I think is the same message than Mada...
