Micro-service high availability deployment method based on RabbitMQ and HAProxy

Abstract

The invention provides a micro-service high-availability deployment method based on RabbitMQ and HAProxy, and the method comprises the steps: carrying the architecture of a distributed micro-service system, taking an HAProxy module as a call entry, and taking a RabbitMQ cluster as a message queue; setting a message persistence and message confirmation mechanism in a RabbitMQ node, and configuring a RabbitMQ cluster, so that a communication message is reliably transmitted; defining a state machine Saga instance, defining a corresponding state machine through fluent grammar, registering the state machine Saga instance to ReceiveEndpoint, and achieving the configuration of final consistency of communication message data; arranging KeepAlived in the HAProxy module, and continuously carrying out the fault detection on the nodes of the two HAProxy servers. According to the invention, the standby HAProxy server can be quickly switched, the shutdown time of the system is minimized, the reliability of the micro-service system is improved, and meanwhile, the fault loss is greatly reduced; and multi-system cooperative operation, flexible deployment and expansion performance improvement can be realized.

Description

technical field [0001] The present invention relates to the technical field of service communication, in particular to a high-availability deployment method for microservices based on RabbitMQ and HAProxy. Background technique [0002] The main task of the remote sensing satellite data receiving system is to search and track satellites, receive and record satellite remote sensing data, telemetry data and satellite attitude data. The remote sensing satellite data receiving system is functionally divided into an antenna feed subsystem, a transmitting subsystem, a receiving channel subsystem, a multifunctional digital baseband subsystem, a modem subsystem, a monitoring subsystem, etc. [0003] The software system of the traditional remote sensing satellite data receiving system adopts a centralized architecture, and the deployment structure is simple. All business units of the entire system are deployed on a single node, and all functions are processed centrally. To a certain ...

Problems solved by technology

[0005] (1) The existing remote sensing satellite data receiving system usually adopts a single client/server architecture. The redundant backup design of equipment and software is simple, and it is easy to have a single point of failure, and the fault recovery process is complicated, and the long-term stable operation performance is poor.
