I followed the plone install guide from the docs.
It goes well and I can access Plone at localhost:8080 . Now I'd like to change the port to 80 so I edit the buildout file, change http-address = 8080
to http-address = 80
, build the thing and restart the plone service.
I'd expect to be able to access it now without the :8080 suffix but alas...
How can I achieve this?
As sdupton says in the comments, don't do it.
Use Nginx to front it.
