One server with two rails applications

Rails
1

Hello all,

I have one machine and two ruby applications, app1 and app2.
Currently, I have an Apache server and a mongrel server. Apache runs
on port 80 and proxies to mongrel on port 3001, which runs app1. But
I wish to run both applications on the one machine. There is
documentation that suggests clustering. But each application will
need it’s own URL, http://localhost/app1 and http://localhost/app2.
Can anyone direct me on how to do this?

Thanks,

j

Apache rewrite rules that rewrites urls matching /app1 to the balancer
(or the single instance if you’re not using mod_proxy_balancer) for the
first mongrel and similarly for the second ?

John - you’re gonna want to look into virtual hosts.

Virtual hosts allow you to serve multiple sites from one IP address.

Here’s a sample server_one.com vhost. Sending server_one.com requests
to a cluster of 4 mongrels- Duplicate it, and change for a second to
answer on the same ip. Not the below may need some more params to
work plus the correct mods installed.

ServerName www. server_one.com

ServerAlias www. server_one.com server_one.com

DocumentRoot /var/www/apps/server_one/current/public

<Proxy balancer://server_one_cluster>
BalancerMember http://127.0.0.1:6000
BalancerMember http://127.0.0.1:6001
BalancerMember http://127.0.0.1:6002
BalancerMember http://127.0.0.1:6003

But neither app1 nor app2 will have URLs like that by default.

How do you configure Rails to prepend “/app1” to every URL that it
creates?

You could fix that with routing I think. Or you could go the virtual
host way (my preference)

Try this guide for full setup of Apache (with virtual hosts) and a
mongrel cluster.

? Can you be more explicit?

But that’s not what the OP asked for.

And for future reference I’d also like to know if it’s possible…

I changed map.connect ‘:controller/:action/:id’ to
map.connect ‘foo/:controller/:action/:id’
and restarted the server.

If you choose this approach you are, as far as I can gather, forced to
change all your hrefs & forms in the applications to mimic this sort
of set up.
I.e application: test, controller: teams, action: list
URL: http://localhost/test/teams/list
But it is quite a job to rename all the URLs in the application.

Is there another way around this?

Setting the routes as I did should automatically prepend test/ to
urls generated from url_for (or the things that use it (form_tag/for,
link_to etc…); at least it did when I tried it.

I use this setup, just pass --prefix=/app1 or --prefix=/app2 into
mongrel. The only changes you will need to make are image urls in
your stylesheets.
