How to restore mysql database in XAMPP?

Question

I have a backup of the entire xampp/mysql folder. How can I use it to recover my old db on a fresh installation of XAMPP?

Simply copying the old

Answer 1

I got the following logs:

2020-02-11 14:26:06 0 [ERROR] mysqld: Table '.\mysql\db' is marked as crashed and last (automatic?) repair failed 2020-02-11 14:26:06 0 [ERROR] Fatal error: Can't open and lock privilege tables: Table '.\mysql\db' is marked as crashed and last (automatic?) repair failed 2020-02-11 14:26:06 0 [ERROR] Aborting

Well, what I did as follows:

1. Installed a new instance of XAMPP in a different directory (e.g. C:\xampp_new)
2. Copied back the three db files from the new installation to the old one:

• C:\xampp_new\mysql\data\mysql\db.frm to C:\xampp\mysql\data\mysql\db.frm

• C:\xampp_new\mysql\data\mysql\db.MAD to C:\xampp\mysql\data\mysql\db.MAD

• C:\xampp_new\mysql\data\mysql\db.MAI to C:\xampp\mysql\data\mysql\db.MAI

3. Started MySQL service from XAMPP then it worked well.

I hope it could also be useful information for those who steps into an error like this.

Be careful when you are trying to set privileges.
