Wt

h1. FastCGI on lighttpd

• Table of contents
• FastCGI (mod_fastcgi)

h3. OpenSUSE configuration

• On OpenSUSE the lighttpd is in the factory tree at repos.opensuse.org http://repos.opensuse.org:/http/SUSE_Linux_10.1/i586/lighttpd-1.4.15-6.1.i586.rpm
• Store the wt application in /srv/www/cgi-bin /srv/www/cgi-bin/helloworld.fcgi
• The OpenSUSE lighttpd configuration are modular - create a new file /etc/lighttpd/conf.d/helloworld.conf fastcgi.server += ("/helloworld" => ("helloworld" => ("socket" => "/usr/wt/socket", "bin-path" => "/srv/www/cgi-bin/helloworld.fcgi", "max-procs" => 1, "check-local" => "disable", "bin-environment" => ("FOO" => "bar") ) ) )

• in /etc/lighttpd/modules.conf
  enable the following (existing) section
  
  ##

  FastCGI (mod_fastcgi)¶

  ##
  include "conf.d/fastcgi.conf"
  
  append an include line at the end of the modules.conf file
  
  include "conf.d/helloworld.conf"

• When done you can access the application on htpp://your.server/helloworld

h3. Flat File Configuration

If you have a single configuration file, add such a section

server.modules += ( "mod_fastcgi" )
fastcgi.server += ("/helloworld" =>
("helloworld" =>
("socket" => "/usr/wt/socket",
"bin-path" => "/srv/www/cgi-bin/helloworld.fcgi",
"max-procs" => 1,
"check-local" => "disable",
"bin-environment" => ("FOO" => "bar")
)
)
)

• When done you can access the application on htpp://your.server/helloworld

h3. /usr/wt

The FastCGI socket has been put into /usr/wt/socket because the default Wt build does put its own session server sockets as $prefix/wt/run/server-$X. There is no requirement to let the lighttpd precreate FastCGI Wt servers to handle different connections as Wt will schedule server creation and session scheduling internally. The internal creation of session servers is not logged to httpd log (where it should be).
