Anyone have success installing it with apache alias (not on root) or with mod_proxy?

Hi guys,

I’m trying to configure dreamfactory with mod_alias or mod_proxy. With both attempts got 404:
Alias /df /opt/dreamfactory/public
I see login screen, but when try to login got 404:
I’ve tried with rewrite:
RewriteRule ^api$ /df/api? [L,R=301] with no success

Any suggestions?
