我有两台服务器，一台是GPU服务器，另一台是CPU服务器；
我在GPU服务器上安装了Ollama，然后通过命令映射端口到CPU服务器：
ssh -CNg -L 0.0.0.0:11434:127.0.0.1:11434 [email protected] -p 34016
映射成功了在Cpu服务器通过curl http://127.0.0.1:11434 可以看到响应内容：
Ollama is running
内网IP，也可以看到内容：
curl http://192.168.0.137:11434
我现在想通过nginx 代理下，把ollama服务开放到公网
server {
listen 80;
server_name ollama.guifanhua.com;
location / {
proxy_pass http://127.0.0.1:11434;
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;
}
}
域名解析是没问题的，但是公网无论如何都不能代理成功，在公网访问：http://ollama.guifanhua.com的时候报错：
找不到 ollama.guifanhua.com 的网页
找不到与以下网址对应的网页：http://ollama.guifanhua.com/
