nacos中需要配置两处

1. cluster.conf 中全部都需要写公网ip地址 【注：如果是云服务器全部填写公网ip、如果是本地填写 ifconfig 或 ipconfig获取到eth0的IP地址】

1.xx.100.xxx:8848
101.xx.123.xxx:8848
59.38.xxx.xxx:8848

2. application.properties 

### Specify local server's IP: 配置该选项绑定公网ip地址
nacos.inetutils.ip-address=59.xx.137.xxx

VIP服务器这里使用的是Nginx + haproxy

其中nginx 作为http代理8848，haproxy作为grpc代理9848

注意nginx端口如果需要自定义端口，haproxy也需要更改代理端口 在nginx端口的基础上+1000，推荐nginx和nacos使用一样的8848端口

1. nginx.conf

    upstream nacos{
        server 1.14.xxx.234:8848;
        server 101.x5.xxx.xxx:8848;
        server 59.xx.xxx.1x0:8848;
    }
    server {
        listen       8848;
        server_name  localhost;
        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass http://nacos;
            root /nacos/;
        }
