h2. lighttpd config
<pre>
setup {
module_load ( "mod_expire", "mod_fastcgi", "mod_vhost" );
}
# looks for cached pages (with '.html' appended to the url), but only if the file for
# the original url doesn't exists and doesn't end with '.html' (in the first case we already have a file,
# in the second case we don't want to append another '.html' - if a file exists for the url we will still find it)
#
# remove it if your rails app doesn't cache files, or modify it to look somewhere else (depending on your rails application).
# see below for the lua script.
# you can also use "lua.handler" from "mod_lua" instead of "include_lua" if you need high performance with multiple workers.
cached_html {
if !phys.is_file {
if phys.path !$ ".html" {
include_lua "/etc/lighttpd2/cached_html.lua"; "/etc/lighttpd-sandbox/cached_html.lua";
}
}
}
var.vhosts = [];
# ...
var.vhosts = var.vhosts + [
"www.lighttpd.net": ${
docroot "/var/www/servers/www.lighttpd.net/mephisto/public/";
index ("index.html");
cached_html;
# deliver static files directly, forward everything else to the rails application
if physical.is_file {
header.add ("X-cleanurl", "hit");
} else {
header.add ("X-cleanurl", "miss");
fastcgi "unix:/var/run/lighttpd/sockets/www.lighttpd.net.sock";
}
if req.path =~ "\.(png|css|gif)$" {
expire "access 1 week";
}
}
];
# ...
vhost.map var.vhosts;
</pre>
h3. lua script
<pre>
-- /etc/lighttpd2/cached_html.lua /etc/lighttpd-sandbox/cached_html.lua
function try_cached_html(vr)
local p = vr.phys.path .. '.html'
st, res = vr:stat(p)
if st and st.is_file then
-- found the file
vr.phys.path = p
elseif res == lighty.HANDLER_WAIT_FOR_EVENT then
return lighty.HANDLER_WAIT_FOR_EVENT
end
-- ignore other errors
end
actions = try_cached_html
</pre>
h2. spawn rails application
Simple ./run script to spawn rails applications with [[spawn-fcgi:WikiStart|spawn-fcgi]] and runit/daemontools:
<pre>
#!/bin/sh
exec 2>&1
RAILS_ENV="production" \
LANG=C LC_ALL=C \
exec /usr/bin/spawn-fcgi -n -s /var/run/lighttpd/sockets/www.lighttpd.net.sock -u www-default -U www-data -- /var/www/servers/www.lighttpd.net/mephisto/public/dispatch.fcgi
</pre>
h3. dispatch.fcgi
Obviously you need a dispatch.fcgi FastCGI handler, if you don't have one, just try this one:
<pre>
#!/usr/bin/env ruby
require File.dirname(__FILE__) + "/../config/environment"
require 'fcgi_handler'
RailsFCGIHandler.process!
</pre>
