newbie with mysql problem

[Anon]

Hi,

I have a problem with my mysql server running on a mandrake 8.1 machine. I accidentally changed a setting under webmin (user permissions) I changed localhost to all. And now i cant get in at all. And setting it back is also impossible cause i get the message "Access denied for user: '@' to database 'mysql'"

How can i change a standard privileges back? Or is the only solution to install the whole machine from scratch?

Hope someone knows how to solve this.

Yours thankfully,

Kee

Kee,

Generally (unless you've put entries into the host table), your security entries will be held in 2 tables in the mysql database.

a. User
b. Db

Easy solution: (if you have a backup)
1. shutdown mysql.
2. Overwrite the files db. and user. in the mysql directory from the backup.
3. Restart mysql.

If you don't have a backup, drop me a mail and I'll send you a copy of these files with blank passworded root user entries.

Once you've got it working, it's definitely worth scheduling a nightly shutdown and backup of you database files (cron et al.)

Cheers

Justin
