Cloud+Consul-编程知识

Cloud整合Zookeeper代替Eureka-CSDN博客

Consul简介

Consul是一套开源的分布式服务发现和配置管理系统

What is Consul? | Consul | HashiCorp DeveloperConsul is a service networking solution that delivers service discovery, service mesh, and network security capabilities. It supports multi-cloud infrastructure by automating connectivity between cloud providers. Learn how Consul can help you scale operations and provide high availability across your network.https://www.consul.io/intro/index.html

由HashiCorp公司用Go语言开发

提供了微服务系统中的服务治理,配置中心,控制总线等功能,这些功能中的每一个都可以根据需要单独使用,也可以一起使用以构建全方位的服务网格,总之Consul提供了一种完整的服务网格解决方案.

如果没有Alibaba的Nacos 那么Consul ..........学话

基于raft(是一种用于实现分布式系统中的一致性算法,它是为了易于理解和实现而设计的)协议,比较简洁,支持健康检查,同时支持HTTP和DNS协议,支持跨数据中心的wan集群,提供图形界面,跨平台,支持Linux,Mac,Window

Consul安装

Install | Consul | HashiCorp Developer

uname -m

打开您的 Linux 终端或控制台，输入以上任何一个命令，然后按下回车键，就可以看到您的系统架构信息。如果您看到的是 x86_64、i686 或 i386，那么您的系统是基于 AMD 或 Intel 的 x86 架构。如果您看到的是 arm、arm64、aarch64 等，那么您的系统是基于 ARM 架构

yum install -y yum-utils
yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo
yum -y install consul

which consul

nohup consul agent -dev -ui -node=consul-dev -client=122.22.222.222 &

注意后面是内网ip

先这么玩着

启动后

IP:8500

支付模块(生产者)

控制器

@RestController
@Slf4j
public class PaymentController {@Value("${server.port}")private String serverPort;@GetMapping(value = "/payment/consul")public String paymentConsul(){return "springcloud with consul: "+serverPort+"\t"+ UUID.randomUUID().toString();}
}

启动类 @EnableDiscoveryClient可以不加

application.yml

订单模块(消费者)

配置类

@Configuration
public class ApplicationContextConfig {@LoadBalanced@Beanpublic RestTemplate getRestTemplate(){return new RestTemplate();}}

业务类

@RestController
@Slf4j
public class OrderConsulController {public static final String INVOME_URL = "http://consul-provider-payment";@Resourceprivate RestTemplate restTemplate;@GetMapping("/consumer/payment/consul")public String payment (){String result = restTemplate.getForObject(INVOME_URL+"/payment/consul",String.class);return result;}}

启动类

@SpringBootApplication
//@EnableDiscoveryClient//老版本需要  新版不用
public class OrderMain80 {public static void main(String[] args) {SpringApplication.run(OrderMain80.class, args);}
}
