rabbitMQ add Plugin Configuration

[yong]

Hi all;

         I want to connect with rabbitMQ using MQTT, but I don't know how to add plugin configuration as   https://www.rabbitmq.com/mqtt.html#config said .

My environment : ubuntu.

             I tried to add rabbitmq.config  file at location  /etc/rabbitmq  with content:

mqtt.listeners.tcp.default = 1883
## Default MQTT with TLS port is 8883
# mqtt.listeners.ssl.default = 8883

# anonymous connections, if allowed, will use the default
# credentials specified here
mqtt.allow_anonymous  = true
mqtt.default_user     = guest
mqtt.default_pass     = guest

mqtt.vhost            = /
mqtt.exchange         = amq.topic
# 24 hours by default
mqtt.subscription_ttl = 86400000
mqtt.prefetch         = 10

but server cannot run .

If you plan on using the new style config format, the file must be named rabbitmq.conf. See [1][2].

Thanks , it works. But I also cannot receive mosquito mqtt message . Can you help ? Here is my operation :

1. Modify  mosquitto.conf , add below message and restart mosquito mqtt :

connection main
address 192.168.18.82
bridge_attempt_unsubscribe false
bridge_protocol_version mqttv311
bridge_insecure true
log_type debug
topic public out

2. add below configure message in rabbitmq.conf and restart rabbitMQ

mqtt.listeners.tcp.default = 1883
## Default MQTT with TLS port is 8883
# mqtt.listeners.ssl.default = 8883

# anonymous connections, if allowed, will use the default
# credentials specified here
mqtt.allow_anonymous  = true
mqtt.default_user     = guest
mqtt.default_pass     = guest

mqtt.vhost            = /
mqtt.exchange         = amq.topic
# 24 hours by default
mqtt.subscription_ttl = 86400000
mqtt.prefetch         = 10

3. mosquitto publish a messsage and see if rabbitMQ recevice . 

mosquitto_pub -t topic -m "Hello MQTT"

In fact it cannot work , in the http://192.168.18.82:15672/#/queues or  http://192.168.18.82:15672/#/ I cannot see anything . I don't know which step I do wrong or is there anything I
I'm missing .

The fact is that I have a wifi mudule and it can linked with mosquito mqtt  with below information :

AT+MQIPPORT=192.168.18.81,1883
AT+MQUSERPWD=user,123456

Note:

Server IP : 192.168.18.81

IP PORT : 1883

UserName: user

Password : 123456

But I use this message to connect with rabbitMQ, it cannot work  and this is why I 'm make a bridge between mosquitto with rabbitMQ 

Peharps is it possible I can link my device with rabbitMQ directly ? If yes, what should I do in rabbitMQ and what topic I can publish using rabbitMQ default mode ?

[Michael Klishin]

Start with inspecting server logs [1][2] and ensuring that the client can connect [3].

For that the MQTT plugin must be enabled and its port accessible. Default user (guest) can only connect from localhost [4] which is not the case in your examples.

Hi ；

       I add below  message in rabbit.conf to change log file level

    log.file.level = debug

      Here is my rab...@ubuntu.log content ,but it cannot know why I don't receive the message .

=INFO REPORT==== 3-Jul-2019::01:27:42 ===

We don't have sub-second precision in 3.6 logs but what very likely happens is that Mosquitto publishes a message without

waiting for any confirmation and closes the connection. The message is then not guaranteed to be actually processed.

[1][2][3] cover relevant concepts (not specific to MQTT, as the general problem is not).

Using QoS 1 should help with this.

Also, [1] which documents protocol-specific terminology around publisher acknowledgements (including MQTT).

Hi

     Thanks for your help .

Now I can use Trace log to see default Virtual host log , but it cannot add the trace for another Virtual host . I search the net and could not find the result .
