Springcloud Architecture Construction (i) Eureka Server Setup and configurationStart today to learn about Springcloud's knowledge and environment deployment, and to build a set of Springcloud distributed frameworks:This article is only for the first contact or no contact with the small white SpringcloudIf there are any deficiencies, please point out in timeThe purpose of this blog is mainly to learn to communicate and progress together.The first step

is to split a complete application from the data store vertically into multiple different services, each of which can be deployed independently, independently maintained, independently scaled, and invoked between services and services through, for example, restful APIs.For the "micro-service Architecture", we can find a lot of relevant introduction and research articles on the Internet to learn and understand. You can also read the ancestor Martin Fowler's "MicroServices" (Chinese version of tr

Service registration:In the service governance framework, a registry is typically built, and each service unit registers its own services with the registry, informing the registry of additional information such as host and port numbers, version numbers, communication protocols, and so on.The registry organizes the list of services by service name, and the registry also monitors the availability of services in the list in the form of heartbeat detection, removing them from the service if they are

Reference: In a distributed environment such as the microservices architecture, each component needs to be highly available for deployment.Eureka Server High Availability is actually registering itself as a service to other service registries, thus forming a set of mutually registered service registries to synchronize the service inventory to achieve a high availability effect.Building a two-node service registry cluster to Build a node service registry cluster:1. Create the application-peer1.p

choose the latest version to start.Spring Eureka It has two packages based on the Netfix Eureka, and is primarily responsible for the service governance functions in the microservices architecture. Spring Cloud adds spring boot-style automation to Eureka, and we just need to make spring boot build microservices apps easy to integrate with the

We have previously introduced the use of Spring Boot Admin to detect the upper and lower lines of the service, and then the notification function. Article: http://cxytiandi.com/blog/detail/13376 Today we will introduce another way of implementation, in the Eureka Service for detection notification, Eureka provides the way to monitor the event to support the extension.

Instance Name configuration in the native implementation of the Netflix Eureka, the instance name takes the hostname as the default, so that multiple identical instances cannot be started on the same host, so in the spring Cloud Eureka configuration, multiple instances are launched for the same host. The following rules apply:Eureka.instance.instanceid=${spring.application.name}:${random. int}Using the app

Here's an introduction: LoadBalancerClient interface, which is an abstract definition of a load balancer client, let's look at how to consume the service using the Load Balancer Client interface provided by spring Cloud. Refer to the Eureka-server built in the previous article as the Service registry, Eureka-client as the service provider as the basis.1, Pom.xml and e
