SYNOPSIS

use Mojo::Server::Daemon;
my $daemon = Mojo::Server::Daemon->new(listen => ['http://*:8080']);
$daemon->unsubscribe('request')->on(request => sub {
my ($daemon, $tx) = @_;
# Request
my $method = $tx->req->method;
my $path = $tx->req->url->path;
# Response
$tx->res->code(200);
$tx->res->headers->content_type('text/plain');
$tx->res->body("$method request for $path!");
# Resume transaction
$tx->resume;
});
$daemon->run;

DESCRIPTION

Mojo::Server::Daemon is a full featured, highly portable non-blocking I/O HTTP and WebSocket server, with IPv6, TLS, SNI, Comet (long polling), keep-alive and multiple event loop support.

For better scalability (epoll, kqueue) and to provide non-blocking name resolution, SOCKS5 as well as TLS support, the optional modules EV (4.0+), Net::DNS::Native (0.15+), IO::Socket::Socks (0.64+) and IO::Socket::SSL (1.94+) will be used automatically if possible. Individual features can also be disabled with the "MOJO_NO_NDN", "MOJO_NO_SOCKS" and "MOJO_NO_TLS" environment variables.

See ``DEPLOYMENT'' in Mojolicious::Guides::Cookbook for more.

INT, TERM

Shut down server immediately.

EVENTS

Mojo::Server::Daemon inherits all events from Mojo::Server.

ATTRIBUTES

Mojo::Server::Daemon inherits all attributes from Mojo::Server and implements the following new ones.

acceptors

  my $acceptors = $daemon->acceptors;
  $daemon       = $daemon->acceptors(['6be0c140ef00a389c5d039536b56d139']);

Active acceptor ids.

  # Check port
  mu $port = $daemon->ioloop->acceptor($daemon->acceptors->[0])->port;

backlog

  my $backlog = $daemon->backlog;
  $daemon     = $daemon->backlog(128);

Listen backlog size, defaults to "SOMAXCONN".

inactivity_timeout

  my $timeout = $daemon->inactivity_timeout;
  $daemon     = $daemon->inactivity_timeout(5);

Maximum amount of time in seconds a connection can be inactive before getting closed, defaults to the value of the "MOJO_INACTIVITY_TIMEOUT" environment variable or 15. Setting the value to 0 will allow connections to be inactive indefinitely.

ioloop

  my $loop = $daemon->ioloop;
  $daemon  = $daemon->ioloop(Mojo::IOLoop->new);

Event loop object to use for I/O operations, defaults to the global Mojo::IOLoop singleton.

listen

  my $listen = $daemon->listen;
  $daemon    = $daemon->listen(['https://127.0.0.1:8080']);

Array reference with one or more locations to listen on, defaults to the value of the "MOJO_LISTEN" environment variable or "http://*:3000" (shortcut for "http://0.0.0.0:3000").

  # Listen on all IPv4 interfaces
  $daemon->listen(['http://*:3000']);
  # Listen on all IPv4 and IPv6 interfaces
  $daemon->listen(['http://[::]:3000']);
  # Listen on IPv6 interface
  $daemon->listen(['http://[::1]:4000']);
  # Listen on IPv4 and IPv6 interfaces
  $daemon->listen(['http://127.0.0.1:3000', 'http://[::1]:3000']);
  # Allow multiple servers to use the same port (SO_REUSEPORT)
  $daemon->listen(['http://*:8080?reuse=1']);
  # Listen on two ports with HTTP and HTTPS at the same time
  $daemon->listen(['http://*:3000', 'https://*:4000']);
  # Use a custom certificate and key
  $daemon->listen(['https://*:3000?cert=/x/server.crt&key=/y/server.key']);
  # Domain specific certificates and keys (SNI)
  $daemon->listen(
    ['https://*:3000?example.com_cert=/x/my.crt&example.com_key=/y/my.key']);
  # Or even a custom certificate authority
  $daemon->listen(
    ['https://*:3000?cert=/x/server.crt&key=/y/server.key&ca=/z/ca.crt']);

These parameters are currently available:

ca

  ca=/etc/tls/ca.crt

Path to TLS certificate authority file used to verify the peer certificate.

cert

  cert=/etc/tls/server.crt
  mojolicious.org_cert=/etc/tls/mojo.crt

Path to the TLS cert file, defaults to a built-in test certificate.

ciphers

  ciphers=AES128-GCM-SHA256:RC4:HIGH:!MD5:!aNULL:!EDH

TLS cipher specification string. For more information about the format see <https://www.openssl.org/docs/manmaster/apps/ciphers.html#CIPHER-STRINGS>.

key

  key=/etc/tls/server.key
  mojolicious.org_key=/etc/tls/mojo.key

Path to the TLS key file, defaults to a built-in test key.

reuse

  reuse=1

Allow multiple servers to use the same port with the "SO_REUSEPORT" socket option.

single_accept

  single_accept=1

Only accept one connection at a time.

verify

  verify=0x00

TLS verification mode, defaults to 0x03.

version

  version=TLSv1_2

TLS protocol version.

max_clients

  my $max = $daemon->max_clients;
  $daemon = $daemon->max_clients(100);

Maximum number of accepted connections this server is allowed to handle concurrently, before stopping to accept new incoming connections, passed along to ``max_connections'' in Mojo::IOLoop.

max_requests

  my $max = $daemon->max_requests;
  $daemon = $daemon->max_requests(250);

Maximum number of keep-alive requests per connection, defaults to 100.

silent

  my $bool = $daemon->silent;
  $daemon  = $daemon->silent($bool);

Disable console messages.

METHODS

Mojo::Server::Daemon inherits all methods from Mojo::Server and implements the following new ones.

run

  $daemon->run;

Run server and wait for ``SIGNALS''.

start

  $daemon = $daemon->start;

Start or resume accepting connections through ``ioloop''.

  # Listen on random port
  my $id   = $daemon->listen(['http://127.0.0.1'])->start->acceptors->[0];
  my $port = $daemon->ioloop->acceptor($id)->port;
  # Run multiple web servers concurrently
  my $daemon1 = Mojo::Server::Daemon->new(listen => ['http://*:3000'])->start;
  my $daemon2 = Mojo::Server::Daemon->new(listen => ['http://*:4000'])->start;
  Mojo::IOLoop->start unless Mojo::IOLoop->is_running;

stop

  $daemon = $daemon->stop;

Stop accepting connections through ``ioloop''.

DEBUGGING

You can set the "MOJO_DAEMON_DEBUG" environment variable to get some advanced diagnostics information printed to "STDERR".
