FCGIWRAP(8)						      System Manager's Manual						       FCGIWRAP(8)

NAME

       fcgiwrap - serve CGI applications over FastCGI

SYNOPSIS

       fcgiwrap [OPTIONS]

DESCRIPTION

       fcgiwrap  is  a	simple	server	for  running  CGI applications over FastCGI. It hopes to provide clean CGI support to Nginx (and other web
       servers that may need it).

OPTIONS

       -c number
	      Number of fcgiwrap processes to prefork.

       -s socket_url
	      A URL for the listen socket to bind to. By default fcgiwrap expects a listen socket to be passed on file descriptor 0, matching  the
	      FastCGI  convention.   The  recommended  way  to deploy fcgiwrap is to run it under a process manager that takes care of opening the
	      socket.  However,  for  simple  configurations  and  one-off  tests  this  option   may	be   used.   Valid   socket_urls   include
	      unix:/path/to/unix/socket, tcp:dot.ted.qu.ad:port and tcp6:[ipv6_addr]:port.

       -h     Show a help message and exit.

ENVIRONMENT

       When  running, fcgiwrap evaluates these environment variables set by the web server calling an fcgi-script. The variables DOCUMENT_ROOT and
       SCRIPT_NAME will be concatenated and the resulting executable run as CGI script wrapped as FastCGI, with the  remainder	after  the  script
       name  available	as PATH_INFO. To disable PATH_INFO mangling, set up your web server to pass SCRIPT_FILENAME, which should contain the com-
       plete path to the script. Then PATH_INFO will not be modified.

       DOCUMENT_ROOT
	      directory which the script resides in
       SCRIPT_NAME
	      actual executable
       SCRIPT_FILENAME
	      complete path to CGI script. When set, overrides DOCUMENT_ROOT and SCRIPT_NAME

EXAMPLE

       The fastest way to see fcgiwrap do something is to launch it at the command line like this:
       fcgiwrap -s unix:/var/run/fcgiwrap.sock
       Apart from potential permission problems etc., it should be ready to accept FastCGI requests and run CGI scripts.

       Most probably you will want to launch fcgiwrap by spawn-fcgi using a configuration like this:

       FCGI_SOCKET=/var/run/fcgiwrap.sock
       FCGI_PROGRAM=/usr/sbin/fcgiwrap
       FCGI_USER=nginx
       FCGI_GROUP=www
       FCGI_EXTRA_OPTIONS="-M 0700"
       ALLOWED_ENV="PATH"

       Nginx can be configured to have the arbitrary CGI cgit run as FastCGI as follows:

       location / {
	    fastcgi_param DOCUMENT_ROOT /var/www/localhost/htdocs/cgit/;
	    fastcgi_param SCRIPT_NAME	cgit;
	    fastcgi_pass unix:/var/run/fastcgi.sock;
       }
