I'm following this guide to learn how to use spring-rabbit with RabbitMQ. However in this guide, the RabbitMQ configuration is as default(localhost server and with credential as guest/guest). What should I do if I want to connect to an remote RabbitMQ with ip address and credential? I don't know where to set these information in my application.
The application for that guide is a Spring Boot Application.
Add a file application.properties to src/main/resources.
You can then configure rabbitmq properties according to the Spring Boot Documentation - scroll down to the rabbitmq properties...
...
spring.rabbitmq.host=localhost # RabbitMQ host.
...
spring.rabbitmq.password= # Login to authenticate against the broker.
spring.rabbitmq.port=5672 # RabbitMQ port.
...
spring.rabbitmq.username= # Login user to authenticate to the broker.
...
To connect to a cluster, use
spring.rabbitmq.addresses= # Comma-separated list of addresses to which the client should connect.
e.g. server1:5672,server2:5672.
If you don't want to use boot auto configuration, declare a CachingConnectionFactory #Bean yourself and configure it as desired.

I am able to connect to my secure kafka cluster using above configs but i need to programmatically connect via creating bean?
I'm new to Axon server. I tried to work with Axon server with spring boot.
I installed the axon server on one of my cloud instances. when I run the spring boot application, the application finds the local Axon server. but there is no local one in my case.
I couldn't find a method to configure the IP address in the property file. if you know how to configure the remote host of the Axon server in Spring boot application please help me to do it.
The error like below,
Requesting connection details from localhost:8124
Connecting to AxonServer node [localhost:8124] failed: UNAVAILABLE: io exception
Failed to get connection to AxonServer. Scheduling a reconnect in 2000ms
Thanks.
To configure the location of Axon Server, add the following property to the application.properties file:
axon.axonserver.servers=<hostname/ip address>:<port>
If you are running Axon Server on the default port, you can omit the port number.
I am new to Spring Config Server/Client technologies.
I am using a spring config server to hold some config values.
Config clients will connect to the server and get the values.
If i change some of the config values at the config server, then currently I have to refresh the clients to load the config details from config server again by invoking "/refresh" on each client.
Is there anyway the clients will be notified by the config server and they will then reload the configuration again ?
Yes there is a way.
The solution is to use the Spring Cloud Bus. Using this module, you would link multiple clients to the server using a message broker. The only message broker implementation currently supported by this module is AMQP. Once the clients are connected to the server, invoking the endpoint on the server /bus/refresh will automatically broadcast the configuration changes to all the subscribed clients. This therefore means it is possible to reload configuration changes for any number of clients with one single refresh request which originates at the server.
I am new to SCDF and am trying to get started with a RabbitMQ transport layer and SCDF version 1.2.2. I have setup RabbitMQ in a separate VM and have the SCDF local server and SCDF shell jar in one VM. Can someone suggest how I can specify the server details of my RabbitMQ (which is in a different host in the same network) for SCDF to use as a transport.
For reasons outside my control I need to use the MQ setup in a different machine. Please advise.
SCDF doesn't require RabbitMQ and I think you are trying to use RabbitMQ as the binder for your Spring Cloud Stream applications that are orchestrated via SCDF.
You would need to configure the properties mentioned here
You can find more information here on how to specify these properties at SCDF.
I have configured my application with config server and github supported external config files. It works fine when I am having single instance of my application in cloud foundry.
But for multiple instance it is said to implement spring cloud bus to apply external config changes to all the instances. For this I have bind my config server with rabbit MQ instance available on Pivotal Cloud foundry. have added spring.cloud.starter.bus.amqp jar in my build.gradle file.
Problem: But when I am hitting POST request to client app at:
http://server:port/bus/refresh the call goes to controller rather than refreshing all the instances and failing as no mapping for same.
Please let me know if I am missing any configuration to make spring-cloud-bus work.
Thanks in advance!

What are server.servlet-path and management.context-path in client app set to?
I think you might need to send the request to http://host/<management.context-path>/bus/refresh.
Or better yet, to http://config-server-host/monitor so that it publishes a message to a topic in RabbitMQ and all client apps get notified.
