启动Ollama服务
cmd输入ollama serve命令启动服务
如果无法启动，可以尝试退出ollama后重启
常用的Ollama命令
命令 说明 ollama run <模型名> # 例如：ollama run llama2 下载并运行模型 ollama pull <模型名> # 例如：ollama pull mistral 仅下载模型不运行 ollama list 查看已安装的模型列表 ollama rm <模型名> # 例如：ollama rm llama2 删除本地模型 ollama cp <原模型名> <新模型名> 复制模型 ollama create <自定义模型名> -f ./Modelfile 自定义模型执行构建命令 ollama push <自定义模型名> 推送自定义模型到仓库 ollama serve 启动 Ollama 服务器 按 Ctrl+C终止进程，或结束相关后台服务。停止服务器
