application.yml配置

server:
  port: 8888
spring:
  application:
    name: springcloud-zuul-demo
  cloud:
    zookeeper:
      discovery:
        register: true
        enabled: true
        instance-id: 1
        root: /demo
      connect-string: 39.104.124.245:2181
# 在用户访问路径里面有api-member
zuul:
  routes:
    api-a:
      path: /api-member/**
      serviceId: app-member-service
    api-b:
      path: /api-order/**
      # 服务名称 zuul网关默认整合ribbon 自动实现负载均衡
      serviceId: app-order-service

启动Application 添加注解 @EnableZuulProxy

@EnableZuulProxy
@SpringCloudApplication
public class ZuulApplication {

    public static void main(String[] args) {
        new SpringApplicationBuilder(ZuulApplication.class).web(true).run(args);
    }

}

实现Zuul集群

使用Nginx反向代理实现Zuul网关集群，保证每台网关配置数据相同

Nginx配置

http{
        upstream backServer {
        39.104.124.245:8900;
        39.104.124.245:8901;
         }
        server {
               location / {
                        # 指定上游服务器负载均衡服务器
                        proxy_pass http://backServer/;
                        index index.html index.htm;
               }
        }

}
