## 叙述 ##

Nginx Zuul 集群实现高可用网关的两个作用：

*  Nginx通过轮询实现负载均衡
 *  Zuul通过集群实现高可用

### 解决方案 ###

**实现思路：**

**zuul**

网关每个除了端口的差异之外，其他的过滤器，路由都相同。

创建7001，7002，7003端口的网关。

**nginx**

修改配置文件

#配置上游服务器网关端口集群,默认轮询机制
        upstream  backServer{
            server 127.0.0.1:7001 weight=1;
            server 127.0.0.1:7002 weight=1;
            server 127.0.0.1:7003 weight=1;
        }
        server {
            listen       80;
            server_name  nginxtest.com;
            #charset koi8-r;
            #access_log  logs/host.access.log  main;
            location / {
                ### 指定上游服务器负载均衡服务器
                proxy_pass http://backServer/;
                index  index.html index.htm;
            }

**测试：**

启动 **zuul nginx**，见控制台如下：
