## 名字
|
||
|
||
`mqtt-proxy` 只工作在流模式，它可以帮助你根据 MQTT 的 `client_id` 实现动态负载均衡。
|
||
|
||
这个插件支持 MQTT [3.1.* ]( http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html )及[5.0]( https://docs.oasis-open.org/mqtt/mqtt/v5.0/mqtt-v5.0.html )两个协议。
|
||
|
||
## 属性
|
||
|
||
* `protocol_name`: 必选，协议名称，正常情况下应为“ MQTT” 。
|
||
* `protocol_level`: 必选，协议级别，MQTT `3.1.*` 应为 “4” ，MQTT `5.0` 应该是“5”。
|
||
* `upstream.ip`: 必选，将当前请求转发到的上游的 IP 地址，
|
||
* `upstream.port`: 必选，将当前请求转发到的上游的 端口，
|
||
|
||
## 如何启用
|
||
|
||
为了启用该插件，需要先在 `conf/config.yaml` 中首先开启 stream_proxy 配置，比如下面配置代表监听 9100 TCP 端口：
|
||
|
||
```yaml
|
||
...
|
||
router:
|
||
http: 'radixtree_uri'
|
||
ssl: 'radixtree_sni'
|
||
stream_proxy: # TCP/UDP proxy
|
||
tcp: # TCP proxy port list
|
||
- 9100
|
||
dns_resolver:
|
||
...
|
||
```
|
||
|
||
然后把 MQTT 请求发送到 9100 端口即可。
|
||
|
||
下面是一个示例，在指定的 route 上开启了 mqtt-proxy 插件:
|
||
|
||
```shell
|
||
curl http://127.0.0.1:9080/apisix/admin/stream_routes/1 -H 'X-API-KEY: edd1c9f034335f136f87ad84b625c8f1' -X PUT -d '
|
||
{
|
||
"remote_addr": "127.0.0.1",
|
||
"plugins": {
|
||
"mqtt-proxy": {
|
||
"protocol_name": "MQTT",
|
||
"protocol_level": 4,
|
||
"upstream": {
|
||
"ip": "127.0.0.1",
|
||
"port": 1980
|
||
}
|
||
}
|
||
}
|
||
}'
|
||
```
|
||
|
||
#### 禁用插件
|
||
|
||
当你想去掉插件的时候，很简单，在插件的配置中把对应的 json 配置删除即可，无须重启服务，即刻生效：
|
||
|
||
```shell
|
||
$ curl http://127.0.0.1:2379/v2/keys/apisix/stream_routes/1 -X DELETE
|
||
```
|
||
现在就已经移除了 mqtt-proxy 插件了。
