First of all make sure that you have installed Ruby on Rails support. Just run /usr/local/psa/admin/sbin/autoinstaller and select 'Ruby on Rails support' in '13 <+> Plesk hosting features'
that option does not exist under autoinstaller in any section. The options I have under hosting features is:
Bandwidth Limiter For Apache support (mod_bw)
Apache ASP support
Tomcat Java Servlets support
Apache mod_python module
ColdFusion support for Plesk
MIVA Empresa support
Cloudflare Apache Module
I could really use some help to get Ruby on Rails working in Plesk 11
It's sad, buy I could say that there is nothing special for Rails hosting in Plesk 11.
I can recommend you to install ruby, gems and mod_passenger manually (see https://www.phusionpassenger.com/download/#open_source ).
thanks for your reply.. if I had known 2 months ago when I migrated to a new server that I would be getting into ruby on rails then I would have stayed with Plesk 10 instead of moving to the newest version which I expected to be better andit kinda is but lacks some features such as this one. As a Parallels rep has stated above about the autoinstaller, it clearly does not have that option in version 11 but I hope they add it very soon!
