Hello all,
I have problem. I accidently install mysql 5 on my Plesk 8.1 server. Now i Cant access my Plesk panel and all of my webpages are down. Is there any way for example to downgrade to privies version of mysql?
I didn’t make any databases backup lately but I can see there all of them are in /var/lib/mysql but there are not *.sql. I notice also that there are daily backups of main database for plesk /var/lib/psa/dumps.

Could anybody tell me what should I do now?

If you upgraded to MySQL 5, what packages did you install? If you installed server, devel, client, and shared (or shared compat) that should be ok.

First, check /etc/my.cnf and comment out the line


Second, check the permissions of /var/lib/mysql and /var/lib/mysql*

Everything should be owned by mysql.mysql and if it isn't, you will want to correct that.

Now check to see if MySQL starts.
