Mojo::Server::Hypnotoad - ALL GLORY TO THE HYPNOTOAD!

КРАТКИЙ ОБЗОР

  use Mojo::Server::Hypnotoad;
     
  my $toad = Mojo::Server::Hypnotoad->new;
  $toad->run('./myapp.pl', './hypnotoad.conf');

ОПИСАНИЕ

Mojo::Server::Hypnotoad is a full featured UNIX optimized preforking non-blocking I/O HTTP 1.1 and WebSocket server built around the very well tested and reliable Mojo::Server::Daemon with IPv6, TLS, Bonjour, libev and hot deployment support that just works.

To start applications with it you can use the hypnotoad script.

  $ hypnotoad myapp.pl
  Server available at http://127.0.0.1:8080.

You can run the exact same command again for automatic hot deployment.

  $ hypnotoad myapp.pl
  Starting hot deployment for Hypnotoad server 31841.

For Mojolicious and Mojolicious::Lite applications it will default to production mode.

Optional modules EV, IO::Socket::IP, IO::Socket::SSL and Net::Rendezvous::Publish are supported transparently and used if installed.

See Mojolicious::Guides::Cookbook for deployment recipes.

SIGNALS

You can control hypnotoad at runtime with signals.

Manager

INT, TERM
Shutdown server immediately.
QUIT
Shutdown server gracefully.
TTIN
Increase worker pool by one.
TTOU
Decrease worker pool by one.

USR2

Attempt zero downtime software upgrade (hot deployment) without losing any incoming connections.

    Manager (old)
    |- Worker [1]
    |- Worker [2]
    |- Worker [3]
    |- Worker [4]
    `- Manager
              |- Worker [1]
              |- Worker [2]
              |- Worker [3]
              `- Worker [4]

The new manager will automatically send a QUIT signal to the old manager and take over serving requests after starting up successfully.

Worker

INT, TERM
Stop worker immediately.
QUIT
Stop worker gracefully.

CONFIGURATION

Hypnotoad configuration files are normal Perl scripts returning a hash.

    # hypnotoad.conf
    {listen => ['http://*:3000', 'http://*:4000'], workers => 10};

The following parameters are currently available:

accepts

    accepts => 100

Maximum number of connections a worker is allowed to accept before stopping gracefully, defaults to 1000. Setting the value to 0 will allow workers to accept new connections infinitely.

backlog

    backlog => 128

Listen backlog size, defaults to SOMAXCONN.

clients

    clients => 100

Maximum number of parallel client connections per worker process, defaults to 1000.

graceful_timeout

    graceful_timeout => 15

Time in seconds a graceful worker stop may take before being forced, defaults to 30.

group

    group => 'staff'

Group name for worker processes.

heartbeat_interval

    heartbeat_interval => 3

Heartbeat interval in seconds, defaults to 5.

heartbeat_timeout

  heartbeat_timeout => 2

Time in seconds before a worker without a heartbeat will be stopped, defaults to 5.

keep_alive_requests

    keep_alive_requests => 50

Number of keep alive requests per connection, defaults to 25.

keep_alive_timeout

    keep_alive_timeout => 10

Maximum amount of time in seconds a connection can be inactive before being dropped, defaults to 5.

listen

    listen => ['http://*:80']

List of one or more locations to listen on, defaults to <a href="http://">http://</a>*:8080.

lock_file

    lock_file => '/tmp/hypnotoad.lock'

Full path to accept mutex lock file, defaults to a random temporary file.

pid_file

    pid_file => '/var/run/hypnotoad.pid'

Full path to PID file, defaults to hypnotoad.pid in the same directory as the application.

proxy

    proxy => 1

Activate reverse proxy support, defaults to the value of the MOJO_REVERSE_PROXY environment variable.

upgrade_timeout

    upgrade_timeout => 15

Time in seconds a zero downtime software upgrade may take before being aborted, defaults to 30.

user

    user => 'sri'

User name for worker processes.

websocket_timeout

    websocket_timeout => 150

Maximum amount of time in seconds a WebSocket connection can be inactive before being dropped, defaults to 300.

workers

    workers => 10

Number of worker processes, defaults to 4. A good rule of thumb is two worker processes per cpu core.

МЕТОДЫ

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

run

    $toad->run('script/myapp', 'hypnotoad.conf');

Start server.
