Rails - Dec 2004 - Multiple application deployments on a single Apache host

Hi Everyone,

I am setting up Rails for a team of developers to be able to set up 
their own apps easily to play with Rails.  Ideally this would look 
something like:

http://servername/app1/list
http://servername/app2/edit/0
http://servername/app3/show/1
etc...

all on the same server, on port 80

All of the examples I have seen have you set up a single app at a time 
with its own host.  I looked at the FAQ and didn''t see anything.  Can I
have a single host in Apache with multiple "/public" directories that 
run different Rails apps?

What I''ve done in the meantime is gone with a new port for each app, 
adding this section to httpd.conf for new apps

Listen 3000
  < VirtualHost theipaddresshere:3000>
  DocumentRoot /Users/admin/rails/bin/App1/public
  ServerName servername.domain.com

  <Directory "/Users/bob/rails/bin/App1/public/" >
  Options ExecCGI FollowSymLinks
  AddHandler cgi-script .cgi
  AllowOverride all
  Order allow,deny
  Allow from all
  </Directory>

  </VirtualHost>

Obviously this isn''t ideal, but it works fine for testing. 
I''m running
on Mac OS X Panther Server.

Thanks for any ideas!

Damon

Look at the alias directive in apache. You can map in URLs to other
directories this way.

Next you will need to modify the .htaccess file to deal with the
different app[1-3...etc] directories and not default to the root level.

Sorry to be dense here, but I haven''t been able to get these rules 
right.

Can you show one example of the corrected mod_rewrite rules for app1?

Here are the default rewrite rules:

# Default rewriting rules. Change extension from .cgi to .fcgi to 
switch to FCGI and to .rb to switch to mod_ruby
RewriteRule ^([-_a-zA-Z0-9]+)/([-_a-zA-Z0-9]+)/([-_a-zA-Z0-9]+)$ 
/dispatch.cgi?controller=$1&action=$2&id=$3 [QSA] [L]
RewriteRule ^([-_a-zA-Z0-9]+)/([-_a-zA-Z0-9]+)$ 
/dispatch.cgi?controller=$1&action=$2 [QSA] [L]
RewriteRule ^([-_a-zA-Z0-9]+)/$ 
/dispatch.cgi?controller=$1&action=index [QSA] [L]
RewriteRule ^([-_a-zA-Z0-9]+)$ /$1/ [R]

I''ve tried adding /app1/ to both the left hand and right hand side and 
various other combinations, but none of them seem to work correctly.  
Always a 404 it seems, not even showing up in apache.log or 
production.log.

Hitting the /dispatch.cgi directly works to display the scaffolding 
"list" page, except the Show,Edit,Destroy links aren''t right.
It has
something like http://servername/app1/dispatch.cgi/1 for the Show link. 
    How can I get those "magic rails urls"  in the context of multiple
apps?

Thanks in advance,
-damon

Hello,

I posted a page with a apache configuration to do that on the rails wiki, but 
unfortunately it got lost.
I''m attaching it now, because the lines are a bit uncomfortably long
for
email.
With this method you can do what you want just fine, and avoid per directory 
rewriting which is a hack, really.
Of course you have to take care with relative URLs in the application, but 
resource sharing is much easier.

Cheers,

Han Holl
