Mojo::Server::Daemon(3)

NAME
Mojo::Server::Daemon - Non-blocking I/O HTTP and WebSocket server

SYNOPSIS
  use Mojo::Server::Daemon;

  my $daemon = Mojo::Server::Daemon->new(listen => ['http://*:8080']);
  $daemon->unsubscribe('request')->on(request => sub ($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 (4.32+), Net::DNS::Native (0.15+), IO::Socket::Socks (0.64+) and IO::Socket::SSL (2.009+) will be used automatically if possible. Individual features can also be disabled with the "MOJO_NO_NNR", "MOJO_NO_SOCKS" and "MOJO_NO_TLS" environment variables.

See "DEPLOYMENT" in Mojolicious::Guides::Cookbook for more.

SIGNALS
The Mojo::Server::Daemon process can be controlled at runtime with the following signals.

  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 with an active request can be inactive before getting closed, defaults to the value of the "MOJO_INACTIVITY_TIMEOUT" environment variable or 30. 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.

  keep_alive_timeout
  my $timeout = $daemon->keep_alive_timeout;
  $daemon     = $daemon->keep_alive_timeout(10);

Maximum amount of time in seconds a connection without an active request can be inactive before getting closed, defaults to the value of the "MOJO_KEEP_ALIVE_TIMEOUT" environment variable or 5. Setting the value to 0 will allow connections to be inactive indefinitely.

  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']);

  # Listen on UNIX domain socket "/tmp/myapp.sock" (percent encoded slash)
  $daemon->listen(['http+unix://%2Ftmp%2Fmyapp.sock']);

  # File descriptor, as used by systemd
  $daemon->listen(['http://127.0.0.1?fd=3']);

  # 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/man1/ciphers.html#CIPHER-STRINGS>.

fd
      fd=3

    File descriptor with an already prepared listen socket.

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

verify
      verify=0x00

    TLS verification mode.

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.

  ports
  my $ports = $daemon->ports;

Get all ports this server is currently listening on.

  # All ports
  say for @{$daemon->ports};

  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 $port = $daemon->listen(['http://127.0.0.1'])->start->ports->[0];

  # 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_SERVER_DEBUG" environment variable to get some advanced diagnostics information printed to "STDERR".
