Plack::Handler::FCGI(3pm) User Contributed Perl Documentation Plack::Handler::FCGI(3pm) NAME
Plack::Handler::FCGI - FastCGI handler for Plack SYNOPSIS
# Run as a standalone daemon plackup -s FCGI --listen /tmp/fcgi.sock --daemonize --nproc 10 # Run from your web server like mod_fastcgi #!/usr/bin/env plackup -s FCGI my $app = sub { ... }; # Roll your own my $server = Plack::Handler::FCGI->new( nproc => $num_proc, listen => [ $port_or_socket ], detach => 1, ); $server->run($app); DESCRIPTION
This is a handler module to run any PSGI application as a standalone FastCGI daemon or a .fcgi script. OPTIONS listen listen => [ '/path/to/socket' ] listen => [ ':8080' ] Listen on a socket path, hostname:port, or :port. port listen via TCP on port on all interfaces (Same as "listen => ":$port"") leave-umask Set to 1 to disable setting umask to 0 for socket open nointr Do not allow the listener to be interrupted by Ctrl+C nproc Specify a number of processes for FCGI::ProcManager pid Specify a filename for the pid file manager Specify a FCGI::ProcManager sub-class daemonize Daemonize the process. proc-title Specify process title keep-stderr Send STDERR to STDOUT instead of the webserver backlog Maximum length of the queue of pending connections WEB SERVER CONFIGURATIONS In all cases, you will want to install FCGI and FGCI::ProcManager. You may find it most convenient to simply install Task::Plack which includes both of these. nginx This is an example nginx configuration to run your FCGI daemon on a Unix domain socket and run it at the server's root URL (/). http { server { listen 3001; location / { set $script ""; set $path_info $uri; fastcgi_pass unix:/tmp/fastcgi.sock; fastcgi_param SCRIPT_NAME $script; fastcgi_param PATH_INFO $path_info; fastcgi_param QUERY_STRING $query_string; fastcgi_param REQUEST_METHOD $request_method; fastcgi_param CONTENT_TYPE $content_type; fastcgi_param CONTENT_LENGTH $content_length; fastcgi_param REQUEST_URI $request_uri; fastcgi_param SERVER_PROTOCOL $server_protocol; fastcgi_param REMOTE_ADDR $remote_addr; fastcgi_param REMOTE_PORT $remote_port; fastcgi_param SERVER_ADDR $server_addr; fastcgi_param SERVER_PORT $server_port; fastcgi_param SERVER_NAME $server_name; } } } If you want to host your application in a non-root path, then you should mangle this configuration to set the path to "SCRIPT_NAME" and the rest of the path in "PATH_INFO". See <http://wiki.nginx.org/NginxFcgiExample> for more details. Apache mod_fastcgi After installing "mod_fastcgi", you should add the "FastCgiExternalServer" directive to your Apache config: FastCgiExternalServer /tmp/myapp.fcgi -socket /tmp/fcgi.sock ## Then set up the location that you want to be handled by fastcgi: # EITHER from a given path Alias /myapp/ /tmp/myapp.fcgi/ # OR at the root Alias / /tmp/myapp.fcgi/ Now you can use plackup to listen to the socket that you've just configured in Apache. $ plackup -s FCGI --listen /tmp/myapp.sock psgi/myapp.psgi The above describes the "standalone" method, which is usually appropriate. There are other methods, described in more detail at "Standalone_server_mode" in Catalyst::Engine::FastCGI (with regards to Catalyst, but which may be set up similarly for Plack). See also <http://www.fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html#FastCgiExternalServer> for more details. lighttpd To host the app in the root path, you're recommended to use lighttpd 1.4.23 or newer with "fix-root-scriptname" flag like below. fastcgi.server = ( "/" => (( "socket" => "/tmp/fcgi.sock", "check-local" => "disable", "fix-root-scriptname" => "enable", )) If you use lighttpd older than 1.4.22 where you don't have "fix-root-scriptname", mouting apps under the root causes wrong "SCRIPT_NAME" and "PATH_INFO" set. Also, mouting under the empty root ("") or a path that has a trailing slash would still cause weird values set even with "fix-root-scriptname". In such cases you can use Plack::Middleware::LighttpdScriptNameFix to fix it. To mount in the non-root path over TCP: fastcgi.server = ( "/foo" => (( "host" = "127.0.0.1", "port" = "5000", "check-local" => "disable", )) It's recommended that your mount path does NOT have the trailing slash. If you really need to have one, you should consider using Plack::Middleware::LighttpdScriptNameFix to fix the wrong PATH_INFO values set by lighttpd. SEE ALSO
