FastCGI

Managing dispatch.fcgi listeners

========= runit ============

~/Services/rails/rails-{1,2,3,4,5} (there is a model) + ln -s
~/runit/Services/rails/rails-X

========= spinner/spawner.reaper ========

~/Sites/{appname}/script/process/*

======== spawn-fcgi (from lighttpd) =========

Original: Tip: TextDrive and Lighttpd

# create spinner.sh
APP=yourapp
ROOT=$HOME/Sites/$APP
TMP=$ROOT/tmp
ENV=production

RAILS_ENV=$ENV spawn-fcgi -f $ROOT/public/dispatch.fcgi \
   -s $TMP/$APP-0.socket -P $TMP/$APP-0.pid
RAILS_ENV=$ENV spawn-fcgi -f $ROOT/public/dispatch.fcgi \
   -s $TMP/$APP-1.socket -P $TMP/$APP-1.pid

# in lighttpd.conf
fastcgi.server = ( ".fcgi" =>
     ( "localhost" =>
       ( "socket" => "/home/{user}/Sites/{app}/tmp/APP-0.socket" ),
       ( "socket" => "/home/{user}/Sites/{app}/tmp/APP-1.socket" )))

Use the Rails reaper command to restart your application. Restarting lighttpd is a very light, very inexpensive because your fastcgi processes are managed independently.

There is also Rakefile for fcgi listeeners restart
