nacos:
  server-addr: 192.168.10.176:28848
  ip: 192.168.10.176
  port: 30024
  enabled: true

这里实际服务在192.168.10.177上

如果ip 端口配置正确，nginx没监听30024的端口

配置nginx监听

    server {
        listen 30024;
        location / {
            proxy_pass http://192.168.10.177:30000/service-survey/;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "Upgrade";
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        }
