|
||||||
## Overview
|
|
||||||
|
|
||||||
eMQTT is a clusterable, massively scalable, fault-tolerant and extensible MQTT V3.1/V3.1.1 broker written in Erlang/OTP.
|
|
||||||
|
|
||||||
eMQTT is aimed to provide a solid-stable broker that could be clusterd to support millions of connections and clients.
|
|
||||||
|
|
||||||

|
||||||
eMQTT is cross-platform, could run on windows, linux, freebsd and mac os x.

## Download, Install
|
|
||||||
|
|
||||||
### Download
|
|
||||||
|
|
||||||
Dowload binary packages from [http://emqtt.io/downloads](http://emqtt.io/downloads].
|
|
||||||
|
|
||||||
Please build from source if no packages for your platform, or contact us.
|
|
||||||
|
|
||||||
### Install
|
|
||||||
|
|
||||||
Extract tgz package to your installed directory. for example:
|
|
||||||
|
|
||||||
```
|
|
||||||
tar xvf emqtt-ubuntu64-0.3.0-beta.tgz && cd emqtt
|
|
||||||
```
|
|
||||||
|
|
||||||
### Startup
|
|
||||||
|
|
||||||
Startup console for debug:
|
|
||||||
|
|
||||||
```
|
|
||||||
cd emqtt && ./bin/emqtt console
|
|
||||||
```
|
|
||||||
|
|
||||||
You could see all RECV/SENT MQTT Packages on console.
|
|
||||||
|
|
||||||
Start as daemon:
|
|
||||||
|
|
||||||
```
|
|
||||||
cd emqtt && ./bin/emqtt start
|
|
||||||
```
|
|
||||||
|
|
||||||
eMQTT occupies 1883 port for MQTT, 8083 for HTTP API.
|
|
||||||
|
|
||||||
### Status
|
|
||||||
|
|
||||||
```
|
|
||||||
cd emqtt && ./bin/emqtt_ctl status
|
|
||||||
```
|
|
||||||
|
|
||||||
### Stop
|
|
||||||
|
|
||||||
```
|
|
||||||
cd emqtt && ./bin/emqtt stop
|
|
||||||
```
|
|
||||||
|
|
||||||

|
|
||||||
```
|
|
||||||
|
|
||||||
## Cluster
|
|
||||||
|
|
||||||
Suppose we cluster two nodes on 'host1', 'host2', Steps:
|
|
||||||
|
|
||||||
### configure and start node on host1
|
|
||||||
|
|
||||||
configure 'etc/vm.args':
|
|
||||||
|
|
||||||
```
|
|
||||||
-name emqtt@host1
|
|
||||||
```
|
|
||||||
|
|
||||||
then start:
|
|
||||||
|
|
||||||
```
|
|
||||||
./bin/emqtt start
|
|
||||||
```
|
|
||||||
|
|
||||||
### configure and start node on host2
|
|
||||||
|
|
||||||
configure 'etc/vm.args':
|
|
||||||
|
|
||||||
```
|
|
||||||
-name emqtt@host2
|
|
||||||
```
|
|
||||||
|
|
||||||
```
|
|
||||||
./bin/emqtt start
|
|
||||||
```
|
|
||||||
|
|
||||||
### cluster two nodes
|
|
||||||
|
|
||||||
Cluster from 'host2':
|
|
||||||
|
|
||||||
```
|
|
||||||
./bin/emqtt_ctl cluster emqtt@host1
|
|
||||||
```
|
|
||||||
|
|
||||||
or cluster from 'host1':
|
|
||||||
|
|
||||||
```
|
|
||||||
./bin/emqtt_ctl cluster emqtt@host2
|
|
||||||
```
|
|
||||||
|
|
||||||
then check clustered nodes on any host:
|
|
||||||
|
|
||||||
```
|
|
||||||
./bin/emqtt_ctl cluster
|
|
||||||
```
|
|
||||||
|
|
||||||
## HTTP API
|
|
||||||
|
|
||||||
eMQTT support HTTP API to publish message from your APP to MQTT client.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|
||||||
```
|
|
||||||
curl -v --basic -u user:passwd -d "qos=1&retain=0&topic=/a/b/c&message=hello from http..." -k http://localhost:8083/mqtt/publish
|
|
||||||
```
|
|
||||||
|
|
||||||
### URL
|
|
||||||
|
|
||||||
```
|
|
||||||
HTTP POST http://host:8083/mqtt/publish
|
|
||||||
```
|
|
||||||
|
|
||||||
### Parameters
|
|
||||||
|
|
||||||
Name | Description

|
|
||||||
## Protocol
|
|
||||||
|
|
||||||
Authentication of users and devices
|
|
||||||
|
|
||||||
Authorization of access to Server resources
|
|
||||||
|
|
||||||
An implementation may restrict access to Server resources based on information provided by the Client such as User Name, Client Identifier, the hostname/IP address of the Client, or the outcome of authentication mechanisms.
|
|
||||||
|
|
||||||
Identify a MQTT User: Peername, ClientId, Username
|
|
||||||
|
|
||||||
|
|
||||||
## Access Rule
|
|
||||||
|
|
||||||
allow | deny Who subscribe | publish Topic | all
|
|
||||||
|
|
||||||
allow {clientid, {regexp, "abcd"}} subscribe "anna"
|
|
||||||
deny {clientid, "xxxx"} publish "#"
|
|
||||||
allow {clientid, "abcd"} publish "#"
|

# MQTT Protocol Guide
|
|
||||||
|
|
||||||
## Server or Broker
|
|
||||||
|
|
||||||
A program or device that acts as an intermediary between Clients which publish Application Messages and Clients which have made Subscriptions.
|
|
||||||
|
|
||||||
A Server Accepts Network Connections from Clients.
|
|
||||||
Accepts Application Messages published by Clients.
|
|
||||||
Processes Subscribe and Unsubscribe requests from Clients.
|
|
||||||
Forwards Application Messages that match Client Subscriptions.
|
|
||||||
|
|
||||||
|
|
||||||
Client ----> Broker(Server) ----> Client
|
|
||||||
|
|
||||||
Publisher ----> Broker -----> Subscriber
|
|
||||||
|
|
||||||
## Subscription and Session
|
|
||||||
|
|
||||||
### Subscription
|
|
||||||
|
|
||||||
A Subscription comprises a Topic Filter and a maximum QoS. A Subscription is associated with a single Session. A Session can contain more than one Subscription. Each Subscription within a session has a different Topic Filter.
|
|
||||||
|
|
||||||
### Session
|
|
||||||
|
|
||||||
A stateful interaction between a Client and a Server. Some Sessions last only as long as the Network
|
|
||||||
|
|
||||||
Connection, others can span multiple consecutive Network Connections between a Client and a Server.
|
|
||||||
|
|
||||||
## Topic Name and Filter
|
|
||||||
|
|
||||||
An expression contained in a Subscription, to indicate an interest in one or more topics. A Topic Filter can include wildcard characters.
|
|
||||||

## Quick Start
|
|
||||||
|
|
||||||
## Startup in Five Minutes
|
|
||||||
|
|
||||||
```
|
|
||||||
$ git clone git://github.com/emqtt/emqttd.git
|
|
||||||
|
|
||||||
$ cd emqttd
|
|
||||||
|
|
||||||
$ make && make dist
|
|
||||||
|
|
||||||
$ cd rel/emqttd
|
|
||||||
|
|
||||||
$ ./bin/emqttd console
|
|
||||||
```
|
|
||||||
|
|
||||||
## Deploy and Start
|
|
||||||
|
|
||||||
### start
|
|
||||||
|
|
||||||
```
|
|
||||||
cp -R rel/emqttd $INSTALL_DIR
|
|
||||||
|
|
||||||
cd $INSTALL_DIR/emqttd
|
|
||||||
|
|
||||||
./bin/emqttd start
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
### stop
|
|
||||||
|
|
||||||
```
|
|
||||||
./bin/emqttd stop
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
## Configuration
|
|
||||||
|
|
||||||
### etc/app.config
|
|
||||||
|
|
||||||
```
|
|
||||||
{emqttd, [
|
|
||||||
{auth, {anonymous, []}}, %internal, anonymous
|
|
||||||
{listen, [
|
|
||||||
{mqtt, 1883, [
|
|
||||||
{acceptors, 4},
|
|
||||||
{max_clients, 1024}
|
|
||||||
]},
|
|
||||||
{mqtts, 8883, [
|
|
||||||
{acceptors, 4},
|
|
||||||
{max_clients, 1024},
|
|
||||||
%{cacertfile, "etc/ssl/cacert.pem"},
|
|
||||||
{ssl, [{certfile, "etc/ssl.crt"},
|
|
||||||
{keyfile, "etc/ssl.key"}]}
|
|
||||||
]},
|
|
||||||
{http, 8083, [
|
|
||||||
{acceptors, 1},
|
|
||||||
{max_clients, 512}
|
|
||||||
]}
|
|
||||||
]}
|
|
||||||
]}
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
### etc/vm.args
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
-name emqttd@127.0.0.1
|
|
||||||
|
|
||||||
-setcookie emqtt
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
When nodes clustered, vm.args should be configured as below:
|
|
||||||
|
|
||||||
```
|
|
||||||
-name emqttd@host1
|
|
||||||
```
|
|
||||||
|
|
||||||
## Cluster
|
|
||||||
|
|
||||||
Suppose we cluster two nodes on 'host1', 'host2', Steps:
|
|
||||||
|
|
||||||
on 'host1':
|
|
||||||
|
|
||||||
```
|
|
||||||
./bin/emqttd start
|
|
||||||
```
|
|
||||||
|
|
||||||
on 'host2':
|
|
||||||
|
|
||||||
```
|
|
||||||
./bin/emqttd start
|
|
||||||
|
|
||||||
./bin/emqttd_ctl cluster emqttd@host1
|
|
||||||
```
|
|
||||||
|
|
||||||
Run './bin/emqttd_ctl cluster' on 'host1' or 'host2' to check cluster nodes.
|
|
||||||
|
|
||||||
## HTTP API
|
|
||||||
|
|
||||||
emqttd support http to publish message.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|
||||||
```
|
|
||||||
curl -v --basic -u user:passwd -d "qos=1&retain=0&topic=a/b/c&message=hello from http..." -k http://localhost:8083/mqtt/publish
|
|
||||||
```
|
|
||||||
|
|
||||||
### URL
|
|
||||||
|
|
||||||
```
|
|
||||||
HTTP POST http://host:8083/mqtt/publish
|
|
||||||
```
|
|
||||||
|
|
||||||
### Parameters
|
|
||||||
|
|
||||||
