The Camping Server for Lighttpd

1. Install Lighttpd.
2. Install FastCGI.
3. Install ruby-fcgi
4. Add to lighttpd.conf:

    server.port                 = 3045                                                                                                
    server.bind                 = "192.168.0.103"                                                                                     
    server.modules              = ( "mod_fastcgi" )                                                                                   
    server.document-root        = "/usr/local/www/data/examples/"                                                                     
    server.errorlog             = "/usr/local/www/data/examples/error.log"                                                            
                                                                                                                                       
    #### fastcgi module                                                                                                               
    fastcgi.server = ( "" => (                                                                                                        
      "localhost" => (                                                                                                                
        "socket" => "/tmp/camping-examples.socket",                                                                                   
        "bin-path" => "/usr/local/www/data/dispatch.rb",                                                                              
        "bin-environment" => ("FORCE_ROOT" => "1"),                                                                                   
        "allow-x-send-file" => "enable",
        "check-local" => "disable",                                                                                                   
        "max-procs" => 1 ) ) )  
   

   These server settings are just an example, change them to suit your needs. However, the FastCGI settings are very finnicky. In particular: mount your app at the empty string "" and add FORCE_ROOT to your environment when you do that.
5. In dispatch.rb:

    #!ruby
    #!/usr/local/bin/ruby                                                                                           
    require 'rubygems'                                                                                                                
    require 'camping/fastcgi'                                                                                                         
    Camping::Models::Base.establish_connection :adapter => 'sqlite3',
      :database => "/tmp/camping.db"                                  
    Camping::FastCGI.serve("/usr/local/data/examples/")
   

Serving One File

The above setup will serve a whole directory, just like TheCampingServer. If you only want to serve one app (at the root) change the last line in dispatch.rb to point to a single file.

 #!ruby
 Camping::FastCGI.serve("/usr/local/data/examples/blog.rb")

Mounting at a Subdirectory

You can certainly mount your app at a subdirectory on the web server. But remove the FORCE_ROOT and be sure the subdirectory name has no closing slash. Lighttpd is very particular about that. Here, let's mount at /myapp.

 server.port                 = 3045                                                                                                
 server.bind                 = "192.168.0.103"                                                                                     
 server.modules              = ( "mod_fastcgi" )                                                                                   
 server.document-root        = "/usr/local/www/data/examples/"                                                                     
 server.errorlog             = "/usr/local/www/data/examples/error.log"                                                            
                                                                                                                                    
 #### fastcgi module                                                                                                               
 fastcgi.server = ( "/myapp" => (                                                                                               
   "localhost" => (                                                                                                                
     "socket" => "/tmp/camping-examples.socket",                                                                                   
     "bin-path" => "/usr/local/www/data/dispatch.rb",                                                                              
     "allow-x-send-file" => "enable",
     "check-local" => "disable",                                                                                                   
     "max-procs" => 1 ) ) )
