h1. Ruby on Rails with Lighttpd
h2. Starting the rails application
In lighttpd 1.4 you have the option to spawn FastCGI backends from lighttpd with the "bin-path" option; but it is recommend to use [[spawn-fcgi:WikiStart|spawn-fcgi]] for that.
Use something like this with daemontools to supervise your rails backends: (./run script, you need a public/dispatch.fcgi for this; most rails applications provide it or an example which you can use)
<pre>
#!/bin/sh
# needs spawn-fcgi version >= 1.6
exec 2>&1
export RAILS_ENV=production
export LANG=en_US.UTF-8
# www-data is the user lighty runs as
exec /usr/bin/spawn-fcgi -s /var/run/lighttpd/rails-application.sock -n -U www-data -u rails-app-user -- /path/to/rails-application/public/dispatch.fcgi
</pre>
h2. Lighttpd 1.4
Get "cleanurl.lua":http://nordisch.org./cleanurl.lua from http://nordisch.org./; the file /path/to/rails-application/public/dispatch.fcgi must exist even if you use something else for spawning (or you may need "check-local" => "disable").
<pre>
$HTTP["host"] == "rails-app.example.org" {
server.document-root = "/path/to/rails-application/public/"
magnet.attract-physical-path-to = ( "/etc/lighttpd/cleanurl.lua" )
fastcgi.server = ( "dispatch.fcgi" =>
((
"socket" => "/var/run/lighttpd/rails-application.sock",
# if you don't use spawn-fcgi you may try this:
# "bin-path" => "/path/to/rails-application/public/dispatch.fcgi",
# "max-procs" => 1,
# "bin-environment" => (
# "RAILS_ENV" => "production",
# "LANG" => "en_US.UTF-8",
# ),
# "bin-copy-environment" => (
# "PATH",
# ),
))
)
}
</pre>
h3. Running rails application in a subdirectory
*Warning*: Not every rails application supports this.
Lets assume you want to have your blog in http://rails-app.example.org/blog, try this:
<pre>
$HTTP["host"] == "rails-app.example.org" {
$HTTP["url"] =~ "^/blog" {
alias.url = (
"/blog" => "/path/to/rails-application/public/",
)
server.document-root = "/path/to/rails-application/public/" # needed so cleanurl.lua finds the right dispatch.fcgi
magnet.attract-physical-path-to = ( "/etc/lighttpd/cleanurl.lua" )
fastcgi.server = ( "dispatch.fcgi" =>
((
"socket" => "/var/run/lighttpd/rails-application.sock",
"strip-request-uri" => "/blog",
))
)
}
}
</pre>
And add this to your rails application config, for example in config/environments/production.rb
<pre>
config.action_controller.relative_url_root = "/blog"
</pre>
h2. Lighttpd 1.5
Get "cleanurl.lua":http://nordisch.org./cleanurl.lua from http://nordisch.org./.
<pre>
$HTTP["host"] == "rails-app.example.org" {
server.document-root = "/path/to/rails-application/public/"
magnet.attract-physical-path-to = ( "/etc/lighttpd/cleanurl.lua" )
$HTTP["url"] == "/dispatch.fcgi" {
proxy-core.backends = ( "unix:/var/run/lighttpd/rails-application.sock" )
proxy-core.protocol = "fastcgi"
proxy-core.allow-x-sendfile = "enable"
}
}
</pre>
h2. Using RubyOnRails in a simple-vhost environment
Let's say: For an easy setup you want to use [[lighttpd:Docs_ModSimpleVhost|simple-vhost]] [[lighttpd:Docs:ModSimpleVhost|simple-vhost]] but still want to separate the rails-installation:
<pre>
$HTTP["host"] == "ruby.example.org" {
server.document-root = "/var/www/site/public/"
fastcgi.server = ...
}
else $HTTP["host"] =~ "" {
simple-vhost.server-root = "/var/www/servers/"
simple-vhost.default-host = "www.example.org"
simple-vhost.document-root = "pages"
}
</pre>
