I managed to install omero and omero web on centos 7. If I use insight, I can login with both the root account and other created. However, using omero web, after entering the credentials and clicking login, the page just refresh to its default (not even wrong password message it displays; if wrong credentials are inserted the message displays).
I tried to look into the log files to identify the problem without success.
OMERO.server/bin/omero config get:
omero.data.dir=/OMERO
omero.db.name=omero_odonto
omero.db.pass=********
omero.db.user=SauchiehallOmeroUser
omero.web.application_server=wsgi-tcp
omero.web.prefix=/omero
omero.web.session_engine=django.contrib.sessions.backends.cache
omero.web.session_expire_at_browser_close=True
