High Availability of rabbitmq Clusters
Rabbitmq is developed using Erlang and clusters are very convenient. Because Erlang is a distributed language, it does not support Server Load balancer itself.
The rabbit mode can be divided into the following three modes: single mode, normal mode, and image mode.
Single Mode: the simplest mode, not the cluster mode.
There is nothing to say.
Normal Mode: the default cl

RABBITMQ is said to have good performance and timeliness, while also providing excellent support for cluster and load deployments, and is ideal for use in larger distributed systems.Rabbit mode is roughly divided into
Introduction
What is Docker
Docker is an open source project that was born in early 2013 and was originally an amateur project within the DotCloud company. It is based on Google's launch of the Go language implementation. The project later joined the Linux Foundation and complied with the Apache 2.0 protocol, and the project code was maintained on GitHub.
