cloud - 将本地蚊子桥接到云代理

Question

我正在尝试将本地 mosquitto(在树莓派上)桥接到某个云代理，以便我可以发送数据并使用该数据控制某些设备。我尝试使用 Cloudmqtt 和 dioty，但没有成功。在 cloudmqtt 的情况下，我被告知 mosquitto.conf 文件一切正常，对于 dioty，我被告知它使用不支持桥接的 Mosca 代理(我被告知我指的是 cloudmqtt 和 dioty支持服务)。有谁知道可以桥接到本地 mosquitto 的远程代理，有人已经尝试过吗？

我考虑过使用一些物联网平台来做到这一点，但我已经读过该平台使用定价，我这样做是出于学习和业余爱好的目的，所以在我学习如何使用它之前，我想继续免费帐户。

编辑:我正在使用 mosquitto 1.4.5，mosquitto.conf 文件如下:

#Place your local configuration in /etc/mosquitto/conf.d/
#
#A full description of the configuration file is at
#/usr/share/doc/mosquitto/examples/mosquitto.conf.example

connection cloudmqtt
address mnumber.cloudmqtt.com:port
topic zaESP8266 in 0
topic ESP8266 out 0
try_private true
notifications false
start_type automatic
remote_usename username_of_the_user_on_cloudmqtt
remote_password password_of the_user_on_cloudmqtt

pid_file /var/run/mosquitto.pid

persistance true
persistance_location /var/lib/mosquitto/

我选择 Cloudmqtt 作为在线 mosquitto 代理的原因是因为我认为本地 mosquitto <--> 远程 mosquitto 桥应该可以工作。而且我可以使用笔记本电脑或手机等客户端，并使用它们向本地代理发布和订阅消息。这样即使我无法访问互联网，我也可以让本地经纪人与本地客户互动。

编辑:我配置了 mosquitto.conf 文件，以便我可以与 test.mosquitto.org 桥接，我添加了这些行:

connection test
address test.mosquitto.org
topic in_topic in 0
topic out_topic out 0
try_private false
notifications false
bridge_attempt_unsubscribe true

现在，我可以在一个终端中使用 mosquitto_sub -t in_topic，在另一个终端中我可以使用 mosquitto_pub -h test.mosquitto.org -t in_topic -m message。我在使用 mosquitto_sub 命令的第一个终端中收到该消息。所以在这之后我假设桥工作得很好是正确的。但我无法弄清楚桥接到 cloudmqtt 似乎是什么问题。

Cloudmqtt 使用 mosquitto mqtt 代理，dioty 从 mosquitto 交叉到 Mosca mqtt 代理，不支持桥接但显然具有更好的可扩展性(此信息已由 dioty 客户服务提供给我)

编辑:我使用 Node-RED 解决了这个桥接问题。刚刚添加了一个 mqqt 输入并将其配置为本地 mosquitto 代理(端口 1883)和两个 mqtt 输出，用于 ​​cloudmqtt 和 DIoTY。

在cloudmqtt上，注册好账号后(可爱的猫是免费的)，去控制面板添加cloudmqtt实例，cloudmqtt会提供用户名和密码给你。在 Node-RED 中，通过添加服务器、用户名、密码和端口为 cloudmqtt 实例配置 mqtt 输出之一。

在 DIoTY 上，您还需要创建帐户或使用 google 或其他帐户登录。当您登录时，您将获得用户名，这将是您的邮件帐户和其他信息，如主机和端口，将发送到电子邮件帐户的密码。因此，要在 Node-RED 中使用它，您需要将主机(服务器)、用户名、密码和端口添加到 mqtt 输出。当您订阅或发布消息时，请记住您有根主题，例如:

/your_mail_account/topic

无论是订阅某个主题还是发布一些消息，您都需要添加根主题作为某种前缀。

完成此配置后，您需要部署更改，就是这样。因此，对于这种类型，我使用了 Node-RED。

I find out that https://www.cloudmqtt.com/docs-faq.html#TLS_SSL

cloudmqtt.com server cert is signed by Comodo, which has the AddTrust CA as root. Most OSs comes with it by default, so can you point to your default trust/CA store.

获取AddTrust CA证书的方法

10. Click Export to Export the certificates and follow the steps in the Certificate Export Wizard, Export File Format choose Base-64 encoded X.509(CER).

11. Save the ca.cer to **C:\Program Files\mosquitto**

方法02

I get the cert here : www.tbs-certificates.co.uk/FAQ/en/357.html

AddTrust CA Root cert : http://www.tbs-x509.com/AddTrustExternalCARoot.crt

1. Copy AddTrustExternalCARoot.crt to C:\Program Files\mosquitto\

将 Mosquitto 桥接到 CloudMQTT

window

I'm using mosquitto 1.4.11, windows, mosquitto.conf file I use difference name(cloud.conf), It look like this:

connection cloudmqtt
address xxx.cloudmqtt.com:<ssl-port>
remote_username <username_of_the_user_on_cloudmqtt>
remote_password <password_of the_user_on_cloudmqtt>
remote_clientid cloud.mqtt
bridge_protocol_version mqttv311
try_private true
notifications false
start_type automatic
topic # both 2
# Method 01
bridge_cafile ca.cer
# Method 02
#bridge_cafile AddTrustExternalCARoot.crt
bridge_insecure false
cleansession false
local_clientid local.mosquitto

Run cmd.exe

C:\Program Files\mosquitto> mosquitto.exe -c cloud.conf -v

1490627692: mosquitto version 1.4.11 (build date 20/02/2017 23:24:29.40) starting

1490627692: Opening ipv4 listen socket on port 1883.
1490627692: Bridge local.mosquitto doing local SUBSCRIBE on topic #

1490627693: Bridge local.mosquitto sending SUBSCRIBE (Mid: 1, Topic: #, QoS: 2)
1490627693: Received SUBACK from local.mosquitto
...

Now, my local mosquitto broker bridged cloudmqtt.com in 2 way communication.
