Mojo::Server::Daemon - Non-blocking I/O HTTP and WebSocket server
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;
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_NNR, MOJO_NO_SOCKS and MOJO_NO_TLS environment variables.
MOJO_NO_NNR
MOJO_NO_SOCKS
MOJO_NO_TLS
See "DEPLOYMENT" in Mojolicious::Guides::Cookbook for more.
The Mojo::Server::Daemon process can be controlled at runtime with the following signals.
Shut down server immediately.
Mojo::Server::Daemon inherits all events from Mojo::Server.
Mojo::Server::Daemon inherits all attributes from Mojo::Server and implements the following new ones.
my $acceptors = $daemon->acceptors; $daemon = $daemon->acceptors(['6be0c140ef00a389c5d039536b56d139']);

Listen backlog size, defaults to SOMAXCONN.
SOMAXCONN
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.

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).

Path to TLS certificate authority file used to verify the peer certificate.
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=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.
fd=3

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=1

SO_REUSEPORT
single_accept=1
Only accept one connection at a time.
verify=0x00
TLS verification mode.
version=TLSv1_2
TLS protocol version.
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.
my $max = $daemon->max_requests; $daemon = $daemon->max_requests(250);
Maximum number of keep-alive requests per connection, defaults to 100.
100
my $bool = $daemon->silent; $daemon = $daemon->silent($bool);
Disable console messages.
Mojo::Server::Daemon inherits all methods from Mojo::Server and implements the following new ones.
my $ports = $daemon->ports;
Get all ports this server is currently listening on.
# All ports say for @{$daemon->ports};
$daemon->run;
Run server and wait for "SIGNALS".
$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;
$daemon = $daemon->stop;
Stop accepting connections through "ioloop".
