架构示意图 4 | 5 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-25.png) 6 | 7 | 只使用Consul的Server模式有以下2个问题： 8 | 9 | * 因为Consul Server数量受到控制所以压力承载（扩展性）是个问题。 10 | * Server很少导致一个Server下会注册很多微服务，当Server挂掉，这个Server节点下注册的微服务都会视为无效。 11 | 12 | 基于上述问题我们在架构中加入Consul Client模式，Client因为加入了LAN gossip协议组成网络中（高速局域网），可以识别故障的Server节点并找到可用的Server节点继续工作，其实Server模式负责的是用WAN gossip协议组成的网络进行跨广域网的数据同步（多个数据中心），这点Client模式是做不到的，Client模式也提供服务的注册和查询，但Client模式不存储节点数据，Client将请求转发给Server进行处理，节点注册数据在Server端是持久化保存的，Client的数量可以无限多，Server的数量是受控制的。总之：Client模式+LAN gossip协议组成了一个数据中心中的各个节点，Server负责投票选出Leader进行数据中心内的数据同步，这个Leader还负责利用WAN gossip协议跨广域网的与其他数据中心进行数据同步。 13 | PS：在Client注册的服务心跳监控检查由Client负责。 14 | 15 | ##

架构示意图 4 | 5 | Consul在生产环境下运行模式分为两种：Server模式和Client模式（dev模式属于开发模式不在这里讨论），我们先用Server模式搭建一个Consul集群,示意图如下： 6 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-08.png) 7 | Consul Server A、B、C是启动的三个Consul服务运行于Server模式下，其中Consul Server C 是“总指挥”，他们的Leader，Consul Server A和B是Follower当“替补”，他们都可以提供注册和查询微服务器的功能。Leader负责给其他Follower同步数据和监控各个节点的健康，Leader是由他们仨根据Raft一致性算法选举出来的，Server模式运行的Consul服务不能太多，推荐3或5个，因为太多开会选举性能不佳，并且个数要求是奇数（选举算法要求）。 8 | spring-cloud-provider是模拟的服务提供者程序，spring-cloud-provider-second也是模式的服务提供者程序只是返回内容上不太一样（便于区分是哪个服务返回），他们都在Consul中注册同一个服务名称：service-provider，spring-cloud-consul-consumer是模拟服务消费者程序，负责使用service-provider服务。 9 | 10 | ## 搭建环境 11 | 12 | 为了测试方便我们使用docker进行部署，上述服务可以从以下地址下载： 13 | 14 | * [Mac安装Docker](https://docs.docker.com/docker-for-mac/) 15 | * [Docker Consul Image](https://learn.hashicorp.com/consul/day-0/containers-guide) 16 | * [其他Docker Image](https://hub.docker.com/u/bluersw) 17 | 18 | bluersw/spring-cloud-consul-consumer 是服务消费者镜像里面运行的程序项目叫spring-cloud-consul-client，因为名字的起的不讲究导致了混乱，spring-cloud-consul-client不是Consul Client。 19 | 20 | ```shell 21 | docker pull consul 22 | docker pull bluersw/spring-cloud-consul-consumer:v1 23 | docker pull bluersw/spring-cloud-provider:v1 24 | docker pull bluersw/spring-cloud-provider-second:v1 25 | ``` 26 | 27 | 启动Consul脚本(Windows版本的Docker运行命令时参数的IP地址要用"ip地址",比如：-client="0.0.0.0")： 28 | 29 | ```shell 30 | docker run -i -t -p 8500:8500 --name=ConsulServer-C consul agent -server -ui -node=Server-C -bootstrap-expect=3 -client=0.0.0.0 31 | 32 | docker run -i -t -p 8501:8500 --name=ConsulServer-A consul agent -server -ui -node=Server-A -bootstrap-expect=3 -client=0.0.0.0 -join=172.17.0.2 33 | 34 | docker run -i -t -p 8502:8500 --name=ConsulServer-B consul agent -server -ui -node=Server-B -bootstrap-expect=3 -client=0.0.0.0 -join=172.17.0.2 35 | ``` 36 | 37 | bootstrap-expect是指最少几个Server模式下的Consul服务，整个集群才启动。 38 | join=172.17.0.2这个地址就是Server-C的IP地址，Server-C是Leader。 39 | 启动后查看127.0.0.1:8500端口查看后台： 40 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-09.png) 41 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-10.png) 42 | 然后启动消费者和生产者docker： 43 | 44 | ```shell 45 | docker run -t -i --name=spring-cloud-provider -p 9001:9001 bluersw/spring-cloud-provider:v1 46 | source /etc/profile 47 | cd /opt 48 | java -jar spring-cloud-provider-0.0.1-SNAPSHOT.jar 49 | 50 | docker run -t -i --name=spring-cloud-provider-second -p 9002:9002 bluersw/spring-cloud-provider-second:v1 51 | source /etc/profile 52 | cd /opt 53 | java -jar spring-cloud-provider-second-0.0.1-SNAPSHOT.jar 54 | 55 | docker run -t -i --name=spring-cloud-consul-consumer -p 9003:9003 bluersw/spring-cloud-consul-consumer:v1 56 | source /etc/profile 57 | cd /opt 58 | java -jar spring-cloud-consul-client-0.0.1-SNAPSHOT.jar 59 | ``` 60 | 61 | 注册服务示例： 62 | 63 | ```text 64 | spring.application.name=spring-cloud-provider-01 65 | server.port=9001 66 | #172.17.0.3是Server-A 67 | spring.cloud.consul.host=172.17.0.3 68 | spring.cloud.consul.port=8500 69 | #注册到consul的服务名称 70 | spring.cloud.consul.discovery.serviceName=service-provider 71 | #以下两项如果不配置健康检查一定失败 72 | spring.cloud.consul.discovery.prefer-ip-address=true 73 | spring.cloud.consul.discovery.health-check-path=/actuator/health 74 | ``` 75 | 76 | ```text 77 | spring.application.name=spring-cloud-provider-02 78 | server.port=9002 79 | #172.17.0.4是Server-B 80 | spring.cloud.consul.host=172.17.0.4 81 | spring.cloud.consul.port=8500 82 | #注册到consul的服务名称 83 | spring.cloud.consul.discovery.serviceName=service-provider 84 | #以下两项如果不配置健康检查一定失败 85 | spring.cloud.consul.discovery.prefer-ip-address=true 86 | spring.cloud.consul.discovery.health-check-path=/actuator/health 87 | 88 | ``` 89 | 90 | 启动后Docker容器内容： 91 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-11.png) 92 | service-provider服务已经注册完毕： 93 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-17.png) 94 | 访问127.0.0.1:9003/TestHello 测试部署结果： 95 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-12.png) 96 | 97 | ## 模拟服务器故障 98 | 99 | ### 关闭Consul Server B 100 | 101 | Consul Server B 已经不能访问： 102 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-13.png) 103 | 从Leader上看Server-B节点已经故障： 104 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-14.png) 105 | 从Leader上看服务service-provider的注册节点检查已经出现红叉： 106 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-15.png) 107 | 因为Consul处理机制consul节点故障其中注册的服务都视为不可用，所以spring-cloud-provider-second服务虽然没有出问题，但已经不再被轮询到，两次访问都是访问的spring-cloud-provider服务。 108 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-16.png) 109 | 110 | ### 恢复Consul Server B 111 | 112 | 重新启动Consul Server B后，一切自动恢复： 113 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-18.png) 114 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-19.png) 115 | 116 | ### 关闭Consul Server C 117 | 118 | 因为关闭Consul Server C是Leader，所以Consul Server C被关闭之后，Leader被Consul Server B接管： 119 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-20.png) 120 | 此时如果spring-cloud-consul-consumer程序不重新启动，那么因为其保留着上次查询服务的缓存所以还可以继续显示正常： 121 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-21.png) 122 | 如果重新启动因为找不到注册服务的Consul Server C会在访问时发生异常： 123 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-22.png) 124 | 125 | ### 恢复Consul Server C 126 | 127 | Consul Server C之后，Leader仍然是Consul Server B 128 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-23.png) 129 | 130 | 相关服务恢复正常，由上面的测试可以知道Consul大致的故障处理策略： 131 | ![Alt text](http://static.bluersw.com/images/spring-cloud-consul-client-24.png) 132 | -------------------------------------------------------------------------------- /spring-cloud-consul-client/ConsumerService.md: -------------------------------------------------------------------------------- 1 | # 调用Consul服务（消费服务） 2 | 3 | ## 依赖项 4 | 5 | 在spring-cloud-consul-client项目中添加依赖项，POM文件内容中添加如下依赖项： 6 | 7 | ```text 8 | 9 | org.springframework.cloud 10 | spring-cloud-starter-consul-discovery 11 | 12 | 13 | 14 | org.springframework.cloud 15 | spring-cloud-starter-openfeign 16 | 17 | 18 | 19 | org.springframework.boot 20 | spring-boot-starter-web 21 | 22 | ``` 23 | 24 | spring-cloud-starter-consul-discovery为Consul提供支持，spring-cloud-starter-openfeign为HTTP请求提供Feign风格的调用，spring-boot-starter-web仅仅为了使用HTTP MVC测试方便。 25 | 26 | ## 配置信息 27 | 28 | ```text 29 | spring.application.name=spring-cloud-consul-client 30 | server.port=9002 31 | spring.cloud.consul.host=127.0.0.1 32 | spring.cloud.consul.port=8500 33 | #设置不需要注册到 consul 中 34 | spring.cloud.consul.discovery.register=false 35 | ``` 36 | 37 | 本测试不用把自己注册到服务中心里：spring.cloud.consul.discovery.register=false，所以在启动类里也不用声明@EnableDiscoveryClient注解。 38 | 39 | ## 远程服务调用接口 40 | 41 | ```java 42 | @FeignClient(name= "service-provider") 43 | public interface ServiceProviderRemote { 44 | 45 | @RequestMapping("/hello") 46 | public String Hello(@RequestParam String name); 47 | } 48 | ``` 49 | 50 | 使用openfeign调用远程服务接口，openfeign是Spring封装后的Feign，本项目中openfeign需要使用spring-cloud-starter-consul-discovery。 51 | 52 | ## 测试消费服务接口 53 | 54 | ```java 55 | @RestController 56 | public class TestConsul { 57 | 58 | @Autowired 59 | ServiceProviderRemote remote; 60 | 61 | @RequestMapping("/TestHello") 62 | public String TestHello(){ 63 | String first = remote.Hello("first-SWS"); 64 | String second = remote.Hello("second-SWS"); 65 | return first + " | " + second; 66 | } 67 | 68 | @RequestMapping("/Test") 69 | public String Test(){ 70 | return "OK"; 71 | } 72 | } 73 | ``` 74 | 75 | 为了测试负载均衡所以调用两次服务接口。 76 | 77 | ## 启动类 78 | 79 | ```java 80 | @SpringBootApplication 81 | @EnableFeignClients 82 | public class SpringCloudConsulClientApplication { 83 | 84 | public static void main(String[] args) { 85 | SpringApplication.run(SpringCloudConsulClientApplication.class, args); 86 | } 87 | 88 | } 89 | ``` 90 | 91 | 在启动类里需要使用@EnableFeignClients注解启动openfeign。 92 | 93 | ##
