Now create a database for Xoops to use (consult your MySQL manual if you don't
know how.
You will need to
chmod 666 ${MY_INSTALLDIR}/mainfile.php
Then browse to http://${VHOST_HOSTNAME}/xoops
When you are done with the installer:
rm -rf ${MY_INSTALLDIR}/install
chmod 444 ${MY_INSTALLDIR}/mainfile.php
