Ubuntu 22 Linux上部署DeepSeek R1保姆式操作详解（ollama方式）

操作系统：Ubuntu Linux 22.04

一、安装模型运行环境

打开链接https://ollama.com/download/linux

1.安装ollama

（1）一条指令即可实现的简易版安装方法（也可称为在线安装）

curl -fsSL https://ollama.com/install.sh | sh

如果提示没有curl命令，运行下面指令，执行过程中如有报错，多试几次即可。

sudo snap install curl

安装完curl后再次执行上面指令，根据电脑配置以及网络情况，所用时间不一，需要耐心等待。

如果想知道install.sh到底做了啥，可以研究它的源码：

（2）手动一步步安装方法（也可成为离线安装），已经使用方式（1）安装的可以跳过这部分内容。

下载和解压ollma包

curl -L https://ollama.com/download/ollama-linux-amd64.tgz -o ollama-linux-amd64.tgz
sudo tar -C /usr -xzf ollama-linux-amd64.tgz

启动ollama

ollama serve

再启动一个命令窗口，敲入下面指令验证ollama服务是否运行

ollama -v

安装AMD GPU

curl -L https://ollama.com/download/ollama-linux-amd64-rocm.tgz -o ollama-linux-amd64-rocm.tgz
sudo tar -C /usr -xzf ollama-linux-amd64-rocm.tgz

安装ARM64专用包

curl -L https://ollama.com/download/ollama-linux-arm64.tgz -o ollama-linux-arm64.tgz
sudo tar -C /usr -xzf ollama-linux-arm64.tgz

把ollama设置为启动服务

首先创建用户和组

sudo useradd -r -s /bin/false -U -m -d /usr/share/ollama ollama
sudo usermod -a -G ollama $(whoami)

其次创建服务文件：/etc/systemd/system/ollama.service，文件内容如下：

[Unit]
Description=Ollama Service
After=network-online.target

[Service]
ExecStart=/usr/bin/ollama serve
User=ollama
Group=ollama
Restart=always
RestartSec=3
Environment="PATH=$PATH"

[Install]
WantedBy=multi-user.target

最后启动服务

sudo systemctl daemon-reload
sudo systemctl enable ollama

安装cuda驱动

运行nvidia-smi指令，定位所需cuda版本，到官网https://developer.nvidia.com/cuda-downloads

上下载对应驱动并安装。

启动ollama

sudo systemctl start ollama
sudo systemctl status ollama

2.验证安装是否成功

在命令窗口中输入下面指令，看ollama版本号是否正常输出。

ollama -v

二、下载DeepSeek R1模型

打开ollama官网首页，点击页面左上角的Models。

在新打开的页面中找到deepseek R1模型，点击它。

选择一个你想使用的模型，查看右边对应的指令。

因为只是测试，验证安装过程，所以这里选择了1.5b，对应的指令为

ollama run deepseek-r1:1.5b

复制它到命令窗口中执行，这是下载DeepSeek的过程，选的参数越大，文件越大，用时也就越长。过程中如果发现下载速度变慢了，可以ctrl+c中断它，重新运行可以获取较快的速度，每次重新运行都是继续上一次的下载进度。我的网速还好，6秒就搞定了。出现success就是安装成功了。

选择哪个参数的模型，可以参考下面的硬件配置：

三、使用本地部署的DeepSeek进行对话

使用ollama启动模型后，在>>>提示符后输入问题，即可进行对话。

敲入/bye命令退出对话界面，如果想重新进入对话模式，可以先用ollama list命令查看有哪些模型，再用ollama run deepseek-r1:1.5b命令启动模型。

四、用chatbox搭建web ui操作界面

每次都使用上面的方式对话，看起来很不习惯，所以需要一个图形界面。

搭建web ui的方法很多，这里使用常见的Chatbox。

到官网箭头指向处下载chatbox软件。

找到下载的文件，右键点击，查看属性，修改为可执行文件。

然后在命令窗口进入到上面文件所在目录，运行./Chatbox-1.11.3-x86_64.AppImage指令，启动chatbox应用。如果报错缺少fuse，先使用sudo apt install fuse指令安装。

正常启动chatbox后可以看到如下界面

五、把搭建的本地deepseek共享给局域网内的其他人

如果只是自己实验或者练练手，到上一步就结束了。如果要把部署的服务共享给企业里的其他人，参考如下步骤。

1.设置环境变量

export OLLAMA_HOST="0.0.0.0"
export OLLAMA_ORIGINS="*"

说明：

OLLAMA_HOST=0.0.0.0：允许服务监听所有网络接口（而非仅本地）。
OLLAMA_ORIGINS=*：允许所有来源的跨域请求（生产环境建议限制为特定域名）。

或通过配置文件修改（推荐）

文件名称与执行指令：~/.ollama/config.json

内容改为：

{ "host": "0.0.0.0", "port": 11434, "origins": ["*"] }

2.开放防火墙

sudo ufw allow 11434/tcp

sudo ufw reload

3.启动服务并验证

启动ollama服务：
ollama serve

获取本机局域网IP：
ifconfig

浏览器打开：
http://<你的本机IP>:11434
若返回模型列表，则配置成功。

4.客户端连接示例（以Chatbox为例）

其它机器安装Chatbox：

设置API：
模型提供方：选择 ollama api
API域名：填写 http://<你的本机IP>:11434
选择已加载的deekseek模型，开始对话。

六、卸载ollama和模型

1.删除ollama服务

sudo systemctl stop ollama
sudo systemctl disable ollama
sudo rm /etc/systemd/system/ollama.service

2.删除ollama文件和目录

sudo rm $(which ollama)

3.删除模型文件、ollama服务用户和用户

sudo rm -r /usr/share/ollama
sudo userdel ollama
sudo groupdel ollama

4.删除相关的库

sudo rm -rf /usr/local/lib/ollama
