2. 运行 ollama
$ ollama run deepseek-r1:1.5b
>>> /bye
多行输入
对于多行输入，可以使用 “”" 包裹文本：
>>> """Hello,
... world!
... """
查看下载的模型
$ ollama list
NAME ID SIZE MODIFIED
deepseek-r1:1.5b e0979632db5a 1.1 GB 2 hours ago
ollama create 用于从 Modelfile 创建模型
$ ollama create mymodel -f ./Modelfile
删除模型
$ ollama rm deepseek-r1:1.5b
复制模型
$ ollama cp deepseek-r1:1.5b my-model
多模态模型
$ ollama run llava "这张图片中有什么？ ~/people.png"
2. 客户端连接服务器
服务器运行：
$ curl http://localhost:11434/api/generate -d '{"model":"deepseek-r1:1.5b"}'
{"model":"deepseek-r1:1.5b","created_at":"2025-08-09T11:20:03.676711152Z","response":"","done":true,"done_reason":"load"}
客户端运行：
$ curl http://49.51.197.197:11434/api/generate -d '{"model":"deepseek-r1:1.5b"}'
curl: (7) Failed to connect to 49.51.197.197 port 11434 after 277 ms: Couldn't connect to server报错
