你可以用标准的 Nginx 反向代理配置来代理 HugeGraph 的三个 server 服务。每个 server 的 REST API 通常监听
8080 端口，Nginx 只需要把请求均衡转发到这三个节点即可。示例配置如下：
```nginx
upstream hugegraph_servers {
server 172.16.44.26:8080;
server 172.16.44.27:8080;
server 172.16.44.28:8080;
}
server {
listen 80;
server_name hugegraph.example.com;
location / {
proxy_pass http://hugegraph_servers;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
```
这样，所有访问 `hugegraph.example.com` 的请求会自动分发到三台 HugeGraph server
节点，实现负载均衡和高可用。你可以根据实际需要调整 `server_name` 和监听端口。
注意事项：
- HugeGraph server 层只负责 API 服务，数据一致性和分布式同步由 store 和 PD 层通过 raft 协议实现，Nginx
只需要代理 REST API 层即可，无需特殊配置。
- 确保每个 server 节点的 `restserver.url` 配置为 `0.0.0.0:8080` 或实际内网 IP:8080，保证 Nginx
能访问到。
- 如果有鉴权需求，Nginx 只需透传相关 header，不需要做特殊处理。
- 只要三台 server 节点配置一致，raft 相关参数正确，Nginx 代理不会影响集群的数据一致性和分布式能力。
HugeGraph server 与 PD 的关系是：server 只负责对外提供 API，内部通过 RPC/HTTP 与 PD、store
层通信，PD 负责集群元数据和调度，store 负责数据存储和同步，raft 共识只在 PD/store 层实现，server 层是无状态的 API
层，适合用 Nginx
做负载均衡。[参考](https://github.com/apache/incubator-hugegraph/blob/58f2d220487cafae9c19db0d889cd0f727e4ea8d/hugegraph-server/README.md)
如需排查代理或集群问题，建议关注各节点日志和网络连通性。
