# eMQTT Get Started
## 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.
## Requires
eMQTT is cross-platform, could run on windows, linux, freebsd and mac os x.
eMQTT requires Erlang R17+ to build from source.
## Featues
### Full MQTT V3.1.1 Support
MQTT V3.1.1 and V3.1 protocol support
QoS0, QoS1, QoS2 Publish and Subscribe
Session Management and Offline Messages
Retained Messages
Passed eclipse paho interoperability tests
### Clusterable, Massively Scalable
Massive Connections Clients Support
Cluster brokers on servers or cloud hosts
Bridge brokers locally or remotelly
## 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
```
## Configuration
### etc/app.config
```
{emqtt, [
%Authetication. Internal, Anonymous Default.
{auth, {anonymous, []}},
{access, []},
{session, [
{expires, 1}, %hours
{max_queue, 1000},
{store_qos0, false}
]},
{retain, [
{store_limit, 100000}
]},
{listen, [
{mqtt, 1883, [
{acceptors, 4},
{max_conns, 1024}
]},
{http, 8083, [
{acceptors, 1},
{max_conns, 512}
]}
]}
]}
```
### etc/vm.args
```
-name emqtt@127.0.0.1
-setcookie emqtt
```
## 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
--------|---------------
qos | QoS(0, 1, 2)
retain | Retain(0, 1)
topic | Topic
message | Message

# ACL
## 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 "#"
allow {peername, "127.0.0.1"} subscribe "$SYS/#"
allow {peername, "127.0.0.1"} subscribe all
allow {clientid, "clientid"} subscribe "#"
allow {clientid, {regexp, "abcd"}} publish "anna"
allow all subscribe all
deny all subscribe all
allow all
deny all

# 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.
## Packet Identifier

## 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
Name | Description
--------|---------------
qos | QoS(0, 1, 2)
retain | Retain(0, 1)
topic | Topic
message | Message
