Publishing messages
|
||||
-------------------
|
||||
|
||||
hbmqtt_pub
|
||||
``hbmqtt_pub`` is a command-line tool which can be used for publishing some messages on a topic. It requires a few arguments like broker URL, topic name, QoS and data to send. Additional options allow more complex use case.
|
||||
|
||||
Publishing ```some_data`` to as ``/test`` topic on is as simple as :
|
||||
::
|
||||
|
||||
$ hbmqtt_pub --url mqtt://test.mosquitto.org -t /test -m some_data
|
||||
[2015-11-06 22:21:55,108] :: INFO - hbmqtt_pub/5135-MacBook-Pro.local Connecting to broker
|
||||
[2015-11-06 22:21:55,333] :: INFO - hbmqtt_pub/5135-MacBook-Pro.local Publishing to '/test'
|
||||
[2015-11-06 22:21:55,336] :: INFO - hbmqtt_pub/5135-MacBook-Pro.local Disconnected from broker
|
||||
|
||||
This will use insecure TCP connection to connect to test.mosquitto.org. ``hbmqtt_pub`` also allows websockets and secure connection:
|
||||
::
|
||||
|
||||
$ hbmqtt_pub --url ws://test.mosquitto.org:8080 -t /test -m some_data
|
||||
[2015-11-06 22:22:42,542] :: INFO - hbmqtt_pub/5157-MacBook-Pro.local Connecting to broker
|
||||
[2015-11-06 22:22:42,924] :: INFO - hbmqtt_pub/5157-MacBook-Pro.local Publishing to '/test'
|
||||
[2015-11-06 22:22:52,926] :: INFO - hbmqtt_pub/5157-MacBook-Pro.local Disconnected from broker
|
||||
|
||||
``hbmqtt_pub`` can read from file or stdin and use data read as message payload:
|
||||
::
|
||||
|
||||
$ some_command | hbmqtt_pub --url mqtt://localhost -t /test -l
|
||||
|
||||
See :doc:`references/hbmqtt_pub` reference documentation for details about available options and settings.
|
||||
|
||||
Subscribing a topic
|
||||
-------------------
|
||||
|
||||
``hbmqtt_sub`` is a command-line tool which can be used to subscribe for some pattern(s) on a broker and get date from messages published on topics matching these patterns by other MQTT clients.
|
||||
|
||||
Subscribing a ``/test/#`` topic pattern is done with :
|
||||
::
|
||||
|
||||
$ hbmqtt_sub --url mqtt://localhost -t /test/#
|
||||
|
||||
This command will run forever and print on the standard output every messages received from the broker. The ``-n`` option allows to set a maximum number of messages to receive before stopping.
|
||||
|
||||
See :doc:`references/hbmqtt_sub` reference documentation for details about available options and settings.
|
||||
|
||||
|
||||
URL Scheme
|
||||
----------
|
||||
|
||||
``hbmqtt_pub`` is a MQTT client that publishes simple messages on a topic from the command line.
|
||||
HBMQTT command line tools use the ``--url`` to establish a network connection with the broker. The ``--url`` parameter value must conform to the `MQTT URL scheme`_. The general accepted form is :
|
||||
::
|
||||

||||
Usage

||||

hbmqtt
|
||||
======
|
||||
|
||||
``hbmqtt`` is a command-line script for running a MQTT 3.1.1 broker.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
``hbmqtt`` usage :
|
||||
::
|
||||
|
||||
hbmqtt --version
|
||||
hbmqtt (-h | --help)

||||

Options
|
||||
-------
|
||||
|
||||
--version HBMQTT version information
|
||||
-h, --help Display ``hbmqtt_sub`` usage help
|
||||
-c Set the YAML configuration file to read and pass to the client runtime.
|
||||
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
|
||||
If ``-c`` argument is given, ``hbmqtt`` will read specific MQTT settings for the given configuration file. This file must be a valid `YAML`_ file which may contains the following configuration elements :
|
||||
|
||||
* ``listeners`` : network bindings configuration list
|
||||
* ``timeout-disconnect-delay`` : client disconnect timeout after keep-alive timeout
|
||||
* ``auth`` : authentication configuration
|
||||
|
||||
Without the ``-c`` argument, the broker will run with the following default configuration:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
listeners:
|
||||
default:
|
||||
type: tcp
|
||||
bind: 0.0.0.0:1883
|
||||
sys_interval: 20
|
||||
auth:
|
||||
allow-anonymous: true
|
||||
plugins:
|
||||
- auth_file
|
||||
- auth_anonymous
|
||||
|
||||
Using this configuration, ``hbmqtt`` will start a broker :
|
||||
|
||||
* listening on TCP port 1883 on all network interfaces.
|
||||
* Publishing ``$SYS``_ update messages every ``20`` seconds.
|
||||
* Allowing anonymous login, and password file bases authentication.
|
||||
|
||||
.. _YAML: http://yaml.org/
|
||||
|
||||
|
||||
Configuration example
|
||||
---------------------
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
listeners:
|
||||
default:
|
||||
max-connections: 50000
|
||||
type: tcp
|
||||
my-tcp-1:
|
||||
bind: 127.0.0.1:1883
|
||||
my-tcp-2:
|
||||
bind: 1.2.3.4:1883
|
||||
max-connections: 1000
|
||||
my-tcp-ssl-1:
|
||||
bind: 127.0.0.1:8883
|
||||
ssl: on
|
||||
cafile: /some/cafile
|
||||
capath: /some/folder
|
||||
capath: certificate data
|
||||
certfile: /some/certfile
|
||||
keyfile: /some/key
|
||||
my-ws-1:
|
||||
bind: 0.0.0.0:8080
|
||||
type: ws
|
||||
timeout-disconnect-delay: 2
|
||||
auth:
|
||||
plugins: ['auth.anonymous']
|
||||
allow-anonymous: true
|
||||
password-file: /some/passwd_file
|
||||
|
||||
This configuration example shows use case of every parameter.
|
||||
|
||||
The ``listeners`` section define 3 bindings :
|
||||
|
||||
* ``my-tcp-1`` : a unsecured TCP listener on port 1883 allowing ``1000`` clients connections simultaneously
|
||||
* ``my-tcp-ssl-1`` : a secured TCP listener on port 8883 allowing ``50000`` clients connections simultaneously
|
||||
* ``my-ws-1`` : a unsecured websocket listener on port 8080 allowing ``50000`` clients connections simultaneously
|
||||
|
||||
Authentication allows anonymous logins and password file based authentication. Password files are required to be text files containing user name and password in the form of :
|
||||
::
|
||||
|
||||
username:password
|
||||
|
||||
where ``password`` should be the encrypted password. Use the ``mkpasswd -m sha-512`` command to build encoded passphrase. Password file example:
|
||||
::
|
||||
|
||||
# Test user with 'test' password encrypted with sha-512
|
||||
test:$6$l4zQEHEcowc1Pnv4$HHrh8xnsZoLItQ8BmpFHM4r6q5UqK3DnXp2GaTm5zp5buQ7NheY3Xt9f6godVKbEtA.hOC7IEDwnok3pbAOip.

Configuration
|
||||
-------------
|
||||
|
||||
If ``-c`` argument is given, ``hbmqtt_sub`` will read specific MQTT settings for the given configuration file. This file must be a valid `YAML`_ file which may contains the following configuration elements :
|
||||
|
||||
* ``keep_alive`` : Keep-alive timeout sent to the broker. Defaults to ``10`` seconds.
|
||||
* ``ping_delay`` : Auto-ping delay before keep-alive timeout. Defaults to 1. Setting to ``0`` will disable to 0 and may lead to broker disconnection.
|
||||
* ``default_qos`` : Default QoS for messages published. Defaults to 0.
|
||||
* ``default_retain`` : Default retain value to messages published. Defaults to ``false``.
|
||||
* ``auto_reconnect`` : Enable or disable auto-reconnect if connectection with the broker is interrupted. Defaults to ``false``.
|
||||
* ``reconnect_retries`` : Maximum reconnection retries. Defaults to ``2``.
|
||||
* ``reconnect_max_interval`` : Maximum interval between 2 connection retry. Defaults to ``10``.
