Last time, I introduced the installation of RabbitMQ under windows and the addition of AMQP extension of PHP. Here, the code of local test is put into the service, so that is to install it again on Linux. But there is no need to use it directly.

I. Cluster Structure
RabbitMQ always records the following four types of internal metadata:
Queue metadata: name and properties of the queue (persistent, can be deleted automatically);
Exchange metadata: Exchange name, type and properties (persistent, etc.);
Binding metadata: A table that records how messages are routed to a queue;
Vhost metad ...

The theoretical basis of Distributed Service Tracking in the industry today comes mainly from Google's paper "Dapper, a Large-Scale Distributed Systems Tracing Infrastructure". The most widely used open source implementation is Zipkin of Twitter. To achieve platform-independent, vendor-independent distributed service tracing, CNCF rel ...

As mentioned earlier, if multiple consumers subscribe to messages in the same Queue at the same time, the messages in the Queue will be shared equally among multiple consumers. At this time, if the processing time of each message is different, it may cause some consumers to be busy all the time, while others will soon finish the wor ...

RabbiMQ is developed with Erlang, which is very convenient for clustering. Erlang is a distributed language by nature, but it does not support load balancing.
RabbitMQ mode can be roughly divided into the following three types:
(1) the first mock exam.
(2) Normal mode (the default cluster mode).
(3) Mi ...

1, Deploy Rabbitmq clusterRabbitmq cluster can be divided into two ways:1. Normal mode: the default cluster mode. The message body only exists on one node;2. Mirror mode: make the required queue into a mirror, which exists in multiple nodes.ha-mode: all: queue to all nodes; exatly: randomly mirror to other nodes; nodes: mirror to the speci ...

In this example, slf4j-log4j12 is used to manage logs, and the logback classic dependency of spring boot start AMQP needs to be excluded to prevent conflicts.
Key points of message queuing
Producers: procedures for sending messages
Consumer: a program that listens for and receives consumer messages
Message: a stream of bin ...
