Hmm, you have several databases missing, you suspect hackers, yet you continue

The golden rule is, at the first sign of any suspicious activity (yes having
several databases deleted does count as suspicious activity!), take the
server off-line, backup all your important data, and investigate.

I think a better question to be asking is *how* they did this. Knowing that
would stand you in good stead to prevent it from happenning in the future.
Depending on the ability of the 'hacker' the logs may be a source of info.

See what you can salvage from the directory where MySQL keeps the databases.
If there's nothing there then your only salvation are in the backups.

1) The RAQs and its siblings seems to be notoriously insecure. You really need
to keep up with any new security updates.
2) A default installation of MySQL is also insecure in that you do not need a
password to use the root account.
As with all break-ins or suspected break-ins, to be on the safe side you
should recover any data that you can (making sure that they haven't been
tainted) then format the hard-disk (or better still, put in a new hard-disk,
keeping the old one for analysis) and re-install.
