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');
$daemon->on(request => sub {
  my ($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, Comet (long polling), keep-alive, connection pooling, timeout, cookie, multipart and multiple event loop support.

For better scalability (epoll, kqueue) and to provide IPv6 as well as TLS support, the optional modules EV (4.0+), IO::Socket::IP (0.20+) and IO::Socket::SSL (1.84+) will be used automatically by Mojo::IOLoop if they are installed. Individual features can also be disabled with the MOJO_NO_IPV6 and MOJO_NO_TLS environment variables.

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

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([]);

Active acceptors.

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://localhost:3000']);

List of one or more locations to listen on, defaults to the value of the MOJO_LISTEN environment variable or http://*: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([qw(http://*:3000 https://*:4000)]);

# Use a custom certificate and key
$daemon->listen(['https://*:3000?cert=/x/server.crt&key=/y/server.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.

cert

cert=/etc/tls/server.crt

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

ciphers

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

Cipher specification string.

key

key=/etc/tls/server.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.

verify

verify=0x00

TLS verification mode, defaults to 0x03.

max_clients

my $max = $daemon->max_clients;
$daemon = $daemon->max_clients(1000);

Maximum number of concurrent client connections, passed along to "max_connections" in Mojo::IOLoop.

max_requests

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

Maximum number of keep-alive requests per connection, defaults to 25.

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.

start

$daemon = $daemon->start;

Start accepting connections.

# Listen on random port
my $id   = $daemon->listen(['http://127.0.0.1'])->start->acceptors->[0];
my $port = $daemon->ioloop->acceptor($id)->handle->sockport;

stop

$daemon = $daemon->stop;

Stop accepting connections.

DEBUGGING

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

MOJO_DAEMON_DEBUG=1
