# rocketmq-mqtt | ||
## Apache RocketMQ MQTT | ||
A new MQTT protocol architecture model, based on which RocketMQ can better support messages from terminals such as IoT devices and Mobile APP. Based on the RocketMQ message unified storage engine, it supports both MQTT terminal and server message sending and receiving. | ||
|
||
## Architecture | ||
The relevant architecture design is introduced in [RIP-33](https://docs.google.com/document/d/1AD1GkV9mqE_YFA97uVem4SmB8ZJSXiJZvzt7-K6Jons/edit#) | ||
|
||
|
||
## Get Started | ||
|
||
### Prerequisites | ||
The queue model of MQTT needs to be based on the lightweight queue feature ([RIP-28](https://github.com/apache/rocketmq/pull/3694)) of RocketMQ. RocketMQ has only supported this feature since version 4.9.3. Please ensure that the installed version of RocketMQ already supports this feature. | ||
|
||
1. Clone | ||
```shell | ||
git clone https://github.com/apache/rocketmq-mqtt | ||
``` | ||
2. Build the package | ||
```shell | ||
cd rocketmq-mqtt | ||
mvn clean package -DskipTests=true assembly:assembly | ||
``` | ||
3. Config | ||
```shell | ||
cp -r target/rocketmq-mqtt ~ | ||
cd ~/rocketmq-mqtt | ||
cd conf | ||
``` | ||
Some important configuration items in the **service.conf** configuration file | ||
|
||
**Config Key** | **Instruction** | ||
----- | ---- | ||
username | used for auth | ||
secretKey | used for auth | ||
NAMESRV_ADDR | specify namesrv address | ||
eventNotifyRetryTopic | notify event retry topic | ||
clientRetryTopic | client retry topic | ||
|
||
4. CreateTopic | ||
|
||
create all first-level topics, including **eventNotifyRetryTopic** and **clientRetryTopic** in the configuration file above. | ||
```shell | ||
sh mqadmin updatetopic -c {cluster} -t {topic} -n {namesrv} | ||
``` | ||
5. Initialize Meta | ||
- Configure Gateway Node List | ||
```shell | ||
sh mqadmin updateKvConfig -s LMQ -k LMQ_CONNECT_NODES -v {ip1,ip2} -n {namesrv} | ||
``` | ||
- Configure the first-level topic list | ||
```shell | ||
sh mqadmin updateKvConfig -s LMQ -k ALL_FIRST_TOPICS -v {topic1,topic2} -n {namesrv} | ||
``` | ||
- Configure a list of wildcard characters under each first-level topic | ||
```shell | ||
sh mqadmin updateKvConfig -s LMQ -k {topic} -v {topic/+} -n {namesrv} | ||
``` | ||
6. Start Process | ||
```shell | ||
cd bin | ||
sh mqtt.sh start | ||
``` | ||
### Example | ||
The mqtt-example module has written basic usage example code, which can be used for reference | ||
|
||
## Protocol Version | ||
The currently supported protocol version is [MQTT 3.1.1](http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.pdf), but the will and retain features are not supported yet | ||
|
||
## Authentication | ||
At present, an implementation based on the HmacSHA1 signature algorithm is provided by default, Refer to **AuthManagerSample**. Users can customize other implementations to meet the needs of businesses to flexibly verify resources and identities. | ||
## Meta Persistence | ||
At present, meta data storage and management is simply implemented through the kvconfig mechanism of namesrv by default, Refer to **MetaPersistManagerSample**. Users can customize other implementations. | ||
