夹江移动网站建设腾讯效果推广
由于业务需求部署的配置 deepseek:32b,linux配置GPU L20 4卡 ,SSD 200g，暂未发现有什么问题，持续观察中
##通用写法，忽略就行，与deepseek无关

deepseek-r1:32b
github地址:https://github.com/ollama/ollama
Linux下执行： curl -fsSL https://ollama.com/install.sh | sh
2.ollama相关命令
ollama 服务相关命令
sudo systemctl stop ollama
sudo systemctl status ollama
sudo systemctl start ollama
sudo systemctl restart ollama1.拉取模型
ollama pull xxx模型2.运行模型
ollama run xxx模型
退出聊天cmd /bye3.移除模型
ollama rm xxx模型4.显示模型信息
ollama show xxx模型5.列出计算机上的模型
ollama list6.列出当前加载的模型
ollama ps7.停止当前正在运行的模型
ollama stop xxx模型=====================
linux相关配置地址：https://github.com/ollama/ollama/blob/main/docs/linux.mdollama服务默认端口 11434,修改ollama配置使其可以监听0.0.0.0和修改端口，可以外网访问
1.修改文件
vim /etc/systemd/system/ollama.service2.增加
[Service]
Environment=“OLLAMA_HOST=0.0.0.0:xxxx”3.重现加载
sudo systemctl daemon-reload
sudo systemctl restart ollama
sudo systemctl status ollama4.查看日志
journalctl -u ollama.service5.执行 ollama 命令需要带上 OLLAMA_HOST=127.0.0.1:xxxx
例如 OLLAMA_HOST=127.0.0.1:xxxx ollama psollama相关模型

官方文档地址：https://github.com/ollama/ollama/blob/main/docs/api.md1.与模型聊天api,默认流式，如果不要流式 配置"stream": falsecurl http://localhost:11434/api/chat -d '{"model": "deepseek-r1:32b","messages": [{ "role": "user", "content": "为什么天空是蓝色的？" }],"stream": false
}'
