NAME ^

FCGI::Engine::Manager - Manage multiple FCGI::Engine instances

SYNOPSIS ^

  #!/usr/bin/perl

  my $m = FCGI::Engine::Manager->new(
      conf => 'conf/my_app_conf.yml'
  );

  my ($command, $server_name) = @ARGV;

  $m->start($server_name)        if $command eq 'start';
  $m->stop($server_name)         if $command eq 'stop';
  $m->restart($server_name)      if $command eq 'restart';
  $m->graceful($server_name)     if $command eq 'graceful';
  print $m->status($server_name) if $command eq 'status';

  # on the command line

  perl all_my_fcgi_backends.pl start
  perl all_my_fcgi_backends.pl stop
  perl all_my_fcgi_backends.pl restart foo.server
  # etc ...

DESCRIPTION ^

This module handles multiple FCGI::Engine instances for you, it can start, stop and provide basic status info. It is configurable using Config::Any, but only really the YAML format has been tested.

Use with Catalyst

Since FCGI::Engine is pretty much compatible with Catalyst::Engine::FastCGI, this module can also be used to manage your Catalyst::Engine::FastCGI based apps as well as your FCGI::Engine based apps.

Use with Plack

Plack support is provided via the FCGI::Engine::Manager::Server::Plackup module. All that is required is setting the server_class parameter in the configuarion and it will Just Work.

EXAMPLE CONFIGURATION ^

Here is an example configuration in YAML, it should be noted that the options for each server are basically the constructor params to FCGI::Engine::Manager::Server and are passed verbatim to it. This means that if you subclass FCGI::Engine::Manager::Server and set the server_class: option appropriately, it should pass any new options you added to your subclass automatically. The third server in the list shows exactly how this is used with a Plack application.
