Start the Erlang node and Rabbit applications in one step: sudo rabbitmq-server
Start Rabbit node: sudo rabbitmq-server-detached in the background
Disable the entire node (including applications): sudo rabbitmqctl stop

What is RABBITMQMQ (Message Queue): A queue of messages that is designed by the server to store a large number of messages and provides a way for the client to operate the queue: the production queue (adding data to the queue), the consumption queue (fetching data from the queue). RABBITMQ is a typical application based on Message Queuing. RABBITMQ
RabbitMQ Message distribution round robin and Message AcknowledgmentI. Message Distribution
Messages in RabbitMQ can only be stored in the Queue. The producer (P) produces messages and finally delivers them to the Queue. The consumer (C) can obtain and consume messages from the Queue.
Multiple consumers can subscribe to the same Queue. In this case, messages i

Install the latest version of RABBITMQ (3.3.1), and enable management plugin, using the default account guest login to the management console, but prompted the login failed.
After looking through the official release document, I learned that because the account guest has all the operation rights, and is the default account, for security reasons, guest users can only use localhost login, It is recommended that you modify the password of the guest user

asynchronous line thread operation is a time-consuming operation, a request to open 2 threads, and a standard configuration of the ECS server supporting the number of concurrent threads around 800, assuming that a thread in 10 seconds to complete, the single server can support up to 400 requests for concurrency, followed by queuing. This situation, it is necessary to consider increasing the server load, embarrassing increase in costs.How Message Queuing RAB
implementation that is written in Erlang and supported by a variety of clients such as Python, Ruby,. NET, Java, JMS, C, PHP, ActionScript, XMPP, stomp, etc., and support Ajax. It is used to store and forward messages in distributed system, which is very good in ease of use, extensibility, high availability and so on. Related Concepts

After reading the RABBITMQ introductory tutorial one or two, I believe you have been able to build your own
application scenarios, the producer, consumer, and rabbitmq services do not run on one machine at the same time.
The following two Java programs are implemented: one producer that sends only one message from the producer, and the other consumer that receives and prints the message.
In the following dialog, "P" is our producer, "C" is our consumer, and the rectangle in the middle is queue (Message Buffer ma
