# [Spring Cloud之Zuul网关集群][Spring Cloud_Zuul] #

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;
    
           }
        }
    
    
    }

网关：

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();
    //   }
       
       
    }
