Plesk won't start

[MoriI]

[Plesk 9.5.4 / CentOS 5]

Suddenly our server stopped working. When we try to connect via http all we get is 403 Permission Denied errors.

When trying to start Plesk, the output is:

[root@d]# /etc/init.d/psa start

and:

SSH works fine.

What can we do to fix the problem?

MySQL server can't be started.

Can't create/write to file '/tmp/ibkyVhex'

Are you sure that you have not changed permissions on /tmp directory at least?

It looks like mysql server is not started there. Did you check it?
