Spring Cloud之Zuul网关集群

Nginx+Zuul 一主一备 或者 轮训多个

在微服务中，所有服务请求都会统一到Zuul网关上。

Nginx 配置：

#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;



 upstream  backServer{
	    server 192.168.8.159:81;
	    server 192.168.8.159:82;
	}

 server {
      listen       80;
      server_name  www.toov5.com;

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

       }
    }


}

yml：

###注册 中心
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8100/eureka/
server:  ##api网关端口号
  port: 81
###网关名称
spring:   ##网关服务名称
  application:
    name: service-zuul
  ###网关名称  
  cloud:
    config:
    ####读取后缀
      profile: dev
      ####读取config-server注册地址
      discovery:
        service-id: confi
    
### 配置网关反向代理    
zuul:
  routes:
    api-member:  ##随便写的
     ### 以 /api-member/访问转发到会员服务   通过别名找
      path: /api-member/**
      serviceId: app-toov5-member  ##别名  如果集群的话  默认整合了ribbon 实现轮训 负载均衡
    api-order:   ##随便写的
        ### 以 /api-order/访问转发到订单服务
      path: /api-order/**
      serviceId: app-toov5-order   ##别名

　　

启动类：

package com.toov5;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy  //开启网关代理
public class AppGateway {
   public static void main(String[] args) {
   SpringApplication.run(AppGateway.class, args);     
}
//   //zuul配置使用config实现实时更新 
//   @RefreshScope
//   @ConfigurationProperties("zuul")
//   public ZuulProperties zuulProperties() {
//       return new ZuulProperties();
//   }
   
   
}
