Lighttpd

Hi All,

I'm new to LightTPD and am having an issue getting two old rails apps to run.

The environment is:
LightTPD 1.4.49
OS: Ubuntu 16.04.4
uname -a: Linux dominiondev 4.4.0-130-generic #156-Ubuntu SMP Thu Jun 14 08:53:28 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
Rails 1.2.3
Ruby 1.8.5 level 52
RubyGems 0.9.2

I managed to get the first app running using the rails script/server lighttpd command with the following config file.

posmaxweb/config/lighttpd.conf

# Default configuration file for the lighttpd web server
# Start using ./script/server lighttpd

server.bind = "10.10.15.10" 
server.port = 81

server.modules           = ( "mod_rewrite", "mod_accesslog", "mod_fastcgi", "mod_compress", "mod_expire" )

server.error-handler-404 = "/dispatch.fcgi" 
server.pid-file          = CWD + "/tmp/pids/lighttpd.pid" 
server.document-root     = CWD + "/public/" 

server.errorlog          = CWD + "/log/lighttpd.error.log" 
accesslog.filename       = CWD + "/log/lighttpd.access.log" 

url.rewrite              = ( "^/$" => "index.html", "^([^.]+)$" => "$1.html" )

compress.filetype        = ( "text/plain", "text/html", "text/css", "text/javascript" )
compress.cache-dir       = CWD + "/tmp/cache" 

expire.url               = ( "/favicon.ico"  => "access 3 days",
                             "/images/"      => "access 3 days",
                             "/stylesheets/" => "access 3 days",
                             "/javascripts/" => "access 3 days" )

# Change *-procs to 2 if you need to use Upload Progress or other tasks that
# *need* to execute a second request while the first is still pending.
fastcgi.server      = ( ".fcgi" => ( "localhost" => (
  "min-procs"       => 1,
  "max-procs"       => 1,
  "socket"          => CWD + "/tmp/sockets/fcgi.socket",
  "bin-path"        => CWD + "/public/dispatch.fcgi",
  "bin-environment" => ( "RAILS_ENV" => "production" )
) ) )

mimetype.assign = (
  ".css"        =>  "text/css",
  ".gif"        =>  "image/gif",
  ".htm"        =>  "text/html",
  ".html"       =>  "text/html",
  ".jpeg"       =>  "image/jpeg",
  ".jpg"        =>  "image/jpeg",
  ".js"         =>  "text/javascript",
  ".png"        =>  "image/png",
  ".swf"        =>  "application/x-shockwave-flash",
  ".txt"        =>  "text/plain" 
)

# Making sure file uploads above 64k always work when using IE or Safari
# For more information, see http://trac.lighttpd.net/trac/ticket/360
$HTTP["useragent"] =~ "^(.*MSIE.*)|(.*AppleWebKit.*)$" {
  server.max-keep-alive-requests = 0
}

The above application runs fine but the second application with the following config file results in a ruby error:

dominion/config/lighttpd.conf

# Default configuration file for the lighttpd web server
# Start using ./script/server lighttpd

server.bind = "10.10.15.10" 
server.port = 82

server.modules           = ( "mod_rewrite", "mod_accesslog", "mod_fastcgi", "mod_compress", "mod_expire" )

server.error-handler-404 = "/dispatch.fcgi" 
server.pid-file          = "/programs/dominion/tmp/pids/lighttpd.pid" 
server.document-root     = "/programs/dominion/public/" 

server.errorlog          = "/programs/dominion/log/lighttpd.error.log" 
accesslog.filename       = "/programs/dominion/log/lighttpd.access.log" 

url.rewrite              = ( "^/$" => "index.html", "^([^.]+)$" => "$1.html" )

compress.filetype        = ( "text/plain", "text/html", "text/css", "text/javascript" )
compress.cache-dir       = "/programs/dominion/tmp/cache" 

expire.url               = ( "/favicon.ico"  => "access 3 days",
                             "/images/"      => "access 3 days",
                             "/stylesheets/" => "access 3 days",
                             "/javascripts/" => "access 3 days" )

# Change *-procs to 2 if you need to use Upload Progress or other tasks that
# *need* to execute a second request while the first is still pending.
fastcgi.server      = ( ".fcgi" => ( "localhost" => (
  "min-procs"       => 1,
  "max-procs"       => 1,
  "socket"          => "/programs/dominion/tmp/sockets/fcgi.socket",
  "bin-path"        => "/programs/dominion/public/dispatch.fcgi",
  "bin-environment" => ( "RAILS_ENV" => "production" )
) ) )

mimetype.assign = (
  ".css"        =>  "text/css",
  ".gif"        =>  "image/gif",
  ".htm"        =>  "text/html",
  ".html"       =>  "text/html",
  ".jpeg"       =>  "image/jpeg",
  ".jpg"        =>  "image/jpeg",
  ".js"         =>  "text/javascript",
  ".png"        =>  "image/png",
  ".swf"        =>  "application/x-shockwave-flash",
  ".txt"        =>  "text/plain" 
)

# Making sure file uploads above 64k always work when using IE or Safari
# For more information, see http://trac.lighttpd.net/trac/ticket/360
$HTTP["useragent"] =~ "^(.*MSIE.*)|(.*AppleWebKit.*)$" {
  server.max-keep-alive-requests = 0
}

The ruby error is:
/programs/dominion/public/../config/boot.rb:19:in `require': no such file to load -- rubygems (LoadError)
from /programs/dominion/public/../config/boot.rb:19
from /programs/dominion/public/../config/environment.rb:11:in `require'
from /programs/dominion/public/../config/environment.rb:11
from /programs/dominion/public/dispatch.fcgi:21:in `require'
from /programs/dominion/public/dispatch.fcgi:21

This error would seem straight forward except that rubygems is installed and is in the ruby load path. Both apps can be started with ./script/console and both run under Webrick. Why does it work in one instance but not the other?

Thanks,
Don
