Copying from:

  https://www.openmicroscopy.org/site/support/omero4/troubleshooting

you may need a file (not a directory) named /etc/hosts with the
following contents:

    127.0.0.1       localhost
    192.168.0.100   my-hostname.lifesci.example.com my-hostname

where "192.168.0.100" is your actual IP, and my-hostname...etc is your
actual hostname.

These steps you were taking were for a complete install. Not that you
have them working, you don't need all of them.

These setup your environment. Always needed.

These create the database. Only needed (successfully) once. If you
remove them from the script you are using, then more will succeed. In
general, though, once the server is installed and your environment
variables are correct, you don't need anything more than:

  bin/omero admin stop

and 

  bin/omero admin start

Best wishes,
~Josh.
