eureka tutorial

Spring CloudSpring Cloud provides tools for developers to quickly build common distributed systems such as configuration management, service discovery, circuit breakers, intelligent routing, micro-proxies, control buses, one-time tokens, global locks, leader elections, distributed sessions, and cluster status.This is the latest version EdgwareOperation Steps1.

We build the following for the Eureka project of Honghu Cloud, the whole construction process is simple, I will record every step of the construction process, I hope to help everyone:1. Create a MAVEN project named Particle-common-eureka, inheriting Particle-commonservice, with the following pom.xml configuration file:xsi:schemalocation= "http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4

Config Server can also add a user name and password. the Config client is accessed through a user name and password. Config Server can also be made into a highly available cluster. Config is used with the Eureka configuration. Register Config server to Eureka. Config Client is also registered to Eureka. PackageCom.itmuch.cloud;Importorg.springframework.boot.Spr

About Spring CloudSpring Cloud is a spring boot-based cloud application development tool for configuration management, service discovery, circuit breakers, intelligent routing, micro-agents, control buses, global locks, decision-making campaigns, Operations such as distributed sessions and cluster state management provide a simple way to develop.Micro-Service ArchitectureSo what is a "microservices architecture"? To put it simply, a microservices architecture is to split a complete application f

1 Service Discovery# # About Service discoveryIn the MicroServices architecture, Service Discovery (Discovery) is one of the key principles. Manually configuring each client or some form of convention is difficult and fragile. Spring Cloud provides several ways to implement service discovery, such as Eureka, Consul, Zookeeper.Spring Cloud is best supported by Eureka, followed by Consul, the zookeeper.2. Cre

High-Availability Registration centerIn a distributed environment such as the microservices architecture, we need to take full account of the failure situation, so that the individual components must be highly available for deployment in a production environment. In the application.yml of Eureka-server we remember two sections of configuration. Let the service registry itself not register itselfEureka: client: #由于该应用为注册中心, so set to false, the rep

as a service registry, Eureka is better than zookeeper. The famous cap theory states that a distributed system cannot meet both C (consistency), a (availability), and p (partition fault tolerance). Because partition fault tolerance p is a must in a distributed system, we can only trade the tradeoff between A and C. So the zookeeper guarantees that the CP Eureka is the AP. Zookeeper guarantee CP

Fault symptom: Down: Indicates deprecation (disconnection. Cause: In a word, a microservice is unavailable at a certain time, and Eureka will not immediately clean up and save the information of the microservice. What is a self-protection model? By default, if eurekaserver does not receive the heartbeat of a microservice instance within a certain period of time, eurekaserver will log off the instance (90 s by default ). However, when a network part

In the microservices architecture, we consider the failure situation, so in a production environment we need to deploy the various components of the service in a highly available deployment.The high availability of Eureka Server is actually to register itself as a service to other service registries, thus forming a set of mutually registered service centers,To achieve a high-availability effect by synchronizing the service list with each other.1.
