Mojo::Server::Hypnotoad - ALL GLORY TO THE HYPNOTOAD!
use Mojo::Server::Hypnotoad; my $toad = Mojo::Server::Hypnotoad->new; $toad->run('./myapp.pl');
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
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.
See Mojolicious::Guides::Cookbook for deployment recipes.
Mojo::Server::Hypnotoad can be controlled at runtime with the following signals.
Shutdown server immediately.
Shutdown server gracefully.
Increase worker pool by one.
Decrease worker pool by one.
Attempt zero downtime software upgrade (hot deployment) without losing any incoming connections.
Manager (old) |- Worker  |- Worker  |- Worker  |- Worker  `- Manager (new) |- Worker  |- Worker  |- Worker  `- Worker 
The new manager will automatically send a
QUITsignal to the old manager and take over serving requests after starting up successfully.
Stop worker immediately.
Stop worker gracefully.
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 => 128
Listen backlog size, defaults to
clients => 100
Maximum number of parallel client connections per worker process, defaults to
graceful_timeout => 15
Maximum amount of time in seconds a graceful worker stop may take before being forced, defaults to
group => 'staff'
Group name for worker processes.
heartbeat_interval => 3
Heartbeat interval in seconds, defaults to
heartbeat_timeout => 2
Maximum amount of time in seconds before a worker without a heartbeat will be stopped, defaults to
inactivity_timeout => 10
Maximum amount of time in seconds a connection can be inactive before getting dropped, defaults to
15. Setting the value to
0 will allow connections to be inactive indefinitely.
keep_alive_requests => 50
Number of keep alive requests per connection, defaults to
listen => ['http://*:80']
List of one or more locations to listen on, defaults to
http://*:8080. See also "listen" in Mojo::Server::Daemon for more examples.
lock_file => '/tmp/hypnotoad.lock'
Full path to accept mutex lock file, defaults to a random temporary file.
lock_timeout => 1
Maximum amount of time in seconds a worker may block when waiting for the accept mutex, defaults to
pid_file => '/var/run/hypnotoad.pid'
Full path to PID file, defaults to
hypnotoad.pid in the same directory as the application.
proxy => 1
Activate reverse proxy support, defaults to the value of the
MOJO_REVERSE_PROXY environment variable.
upgrade_timeout => 30
Maximum amount of time in seconds a zero downtime software upgrade may take before getting canceled, defaults to
user => 'sri'
Username for worker processes.
websocket_timeout => 150
Maximum amount of time in seconds a WebSocket connection can be inactive before getting dropped, defaults to
300. Setting the value to
0 will allow WebSocket connections to be inactive indefinitely.
workers => 10
Number of worker processes, defaults to
4. A good rule of thumb is two worker processes per cpu core.
You can set the
HYPNOTOAD_DEBUG environment variable to get some advanced diagnostics information printed to
