NAME ^

Nginx::Control - Simple class to manage a Nginx server

SYNOPSIS ^

  #!perl
  
  use strict;
  use warnings;
  
  use Nginx::Control;
  
  my ($command) = @ARGV;
  
  my $ctl = Nginx::Control->new(
      config_file => [qw[ conf nginx.conf ]],
      # PID file can also be discovered automatically 
      # from the conf, or if you prefer you can specify
      pid_file    => 'nginx.control.pid',    
  );
  
  $ctl->start if lc($command) eq 'start';
  $ctl->stop  if lc($command) eq 'stop';

DESCRIPTION ^

This is a fork of Lighttpd::Control to work with Nginx, it maintains 100% API compatibility. In fact most of this documentation was stolen too. This is an early release with only the bare bones functionality needed, future releases will surely include more functionality. Suggestions and crazy ideas welcomed, especially in the form of patches with tests.

ATTRIBUTES ^

config_file

This is a Path::Class::File instance for the configuration file.

binary_path

This is a Path::Class::File instance pointing to the Nginx binary. This can be autodiscovered or you can specify it via the constructor.

pid_file

This is a Path::Class::File instance pointing to the Nginx pid file. This can be autodiscovered from the config file or you can specify it via the constructor.

server_pid

This is the PID of the live server.

METHODS ^

start

Starts the Nginx server that is currently being controlled by this instance. It will also run the pre_startup and post_startup hooks.

stop

Stops the Nginx server that is currently being controlled by this instance. It will also run the pre_shutdown and post_shutdown hooks.

is_server_running

Checks to see if the Nginx server that is currently being controlled by this instance is running or not (based on the state of the PID file).

log

Simple logger that you can use, it just sends the output to STDERR via the warn function.

AUGMENTABLE METHODS ^

These methods can be augmented in a subclass to add extra functionality to your control script. Here is an example of how they might be used to integrate with FCGI::Engine::Manager (For a complete, working version of this, take a look at the file 003_basic_with_fcgi_engine.t in the test suite).

  package My::Nginx::Control;
  use Moose;
  
  extends 'Nginx::Control';
  
  has 'fcgi_manager' => (
      is      => 'ro',
      isa     => 'FCGI::Engine::Manager',   
      default => sub {
          FCGI::Engine::Manager->new(
              conf => 'conf/fcgi.engine.yml'
          )            
      },
  );
  
  augment post_startup => sub {
      my $self = shift;
      $self->log('Starting the FCGI Engine Manager ...');
      $self->fcgi_manager->start;        
  };
  
  augment post_shutdown => sub {
      my $self = shift;
      $self->log('Stopping the FCGI Engine Manager ...');
      $self->fcgi_manager->stop; 
  };    
pre_startup
post_startup
pre_shutdown
post_shutdown
