Nvidia 驱动安装和 Ollama 的使用

本文最后更新于 2025年1月2日凌晨

根据同事反馈，高版本的 NVIDIA 驱动兼容性有问题，需要安装 Nvidia 驱动 525.147.05 ，过程中可能需要升级内核。

安装 Nvidia 驱动

查看 Debian 上显卡安装情况。

lspci -nn | egrep -i "3d|display|vga"  
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation AD102 [GeForce RTX 4090] [10de:2684] (rev a1)

查看驱动安装具体的情况。

lsmod | grep nouveau

mxm_wmi                16384  1 nouveau  
i2c_algo_bit           16384  1 nouveau

wmi                    36864  5 video,asus_wmi,wmi_bmof,mxm_wmi,nouveau  
button                 24576  1 nouveau

看来安装的是开源版本的驱动 nouveau，需要先禁用。

echo "blacklist nouveau" | sudo tee /etc/modprobe.d/nouveau-blacklist.conf
sudo update-initramfs -u
sudo update-grub
sudo reboot

重启后，执行 lsmod | grep nouveau 发现已经返回为空了，成功禁用。

执行命令 sudo apt install nvidia-driver firmware-misc-nonfree 安装 NVIDIA Proprietary Driver 报错。

确认 debian 版本 lsb_release -a

No LSB modules are available.  
Distributor ID: Debian  
Description:    Debian GNU/Linux 12 (bookworm)  
Release:        12  
Codename:       bookworm

根据 stackexchange 上的回答，安全升级 Debian 内核的方法是使用 backports 安装。

echo "deb http://deb.debian.org/debian bookworm-backports main" | sudo tee /etc/apt/sources.list.d/debian-backports.list
sudo apt update
sudo apt install -t bookworm-backports linux-image-amd64
sudo reboot

重新启动后，执行 uname -a 发现内核已经成功升级了。

uname -a                                                                          
Linux debian 6.7.12+bpo-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.7.12-1~bpo12+1 (2024-05-06) x86_64 GNU/Linux

重新安装 NVIDIA Proprietary Driver sudo apt install nvidia-driver firmware-misc-nonfree ，这次没有报错了。

nvidia-smi    

NVIDIA-SMI 525.147.05   Driver Version: 525.147.05   CUDA Version: 12.0

NVIDIA Proprietary Driver 525 感觉有问题，过了一段时间后机器出现重启现象，dmesg 显示错误 ACPI BIOS Error (bug) 。

上网搜索错误，有人反馈是 525 驱动问题（不确定）。Debain 系统 Nvidia 驱动有更新，执行 apt upgrade 后成功升级到 535 。

# nvidia-smi

NVIDIA-SMI 535.183.01             Driver Version: 535.183.01   CUDA Version: 12.2

升级 Nvidia 驱动到 535 后，暂未出现重启现象。

安装 ollama

执行下面的命令安装 Ollama

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

下载速度很慢，还是挂线路。

export https_proxy=http://127.0.0.1:7890
export http_proxy=http://127.0.0.1:7890
curl -fsSL https://ollama.com/install.sh | sh

挂上线路后，很快 Ollama 就安装成功了。

ollama 下载 llama3 8b 和 qwen2 7b 模型，执行下面的命令：

ollama pull llama3
ollama pull qwen2:7b

测试 llama3 模型，运行正常。

ollama run llama3

Hi! It's nice to meet you. Is there something I can help you with or would you like to chat?

升级 Ollama

Ollama 0.3.0 支持通过 llama3.1 进行工具调用，有必要升级。参见 [4]

sudo curl -L https://ollama.com/download/ollama-linux-amd64 -o /usr/local/bin/ollama
sudo chmod +x /usr/local/bin/ollama

升级完毕，需要重启 Ollama 服务。

sudo systemctl daemon-reload
sudo systemctl restart ollama

新版本的 Ollama 已经不是一个单独的文件，而是一个 tar.gz 的压缩包。
tar.tgz 中包含了 ollama 运行需要的动态库，在升级前需要将这些动态库删除。

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

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

执行完上述命令后，启动 ollama 检查版本确认是否升级成功。

ollama serve
ollama -v

配置 Ollama

如果需要在浏览器插件（比如沉浸翻译）中调用 Ollama api，涉及 Cross-Origin 访问，需要修改 Ollama 配置。

官方文档提到了相关的设置 [5]，用 vim 直接修改 /etc/systemd/system/ollama.service 中，添加下面内容：

Environment="OLLAMA_HOST=*"

重启 Ollama 服务

sudo systemctl daemon-reload
sudo systemctl restart ollama

在远程主机上，查看 Ollama 端口侦听情况

apt install net-tools
netstat -antp | grep -i ollama

Ollama 默认侦听 127.0.0.1:11434

tcp        0      0 127.0.0.1:11434         0.0.0.0:*               LISTEN      50508/ollama

利用 SSH 将远程主机 Ollama 侦听的端口 11434 转发到本地 127.0.0.1:11434

ssh -N -g -L 127.0.0.1:11434:127.0.0.1:11434 root@1.1.1.1  # 将 1.1.1.1 替换成你的 ip

卸载 Ollama

停止 Ollama 服务

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

删除二进制文件

sudo rm $(which ollama)

删除 Ollama 用户

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

Ollama 的使用

OLLAMA_ORIGINS=* OLLAMA_NUM_PARALLEL=16 ollama serve

OLLAMA_ORIGINS 跨域设置
OLLAMA_NUM_PARALLEL 支持的并行请求数量
OLLAMA_DEBUG 打印调试信息
OLLAMA_LLM_LIBRARY 支持下面的选项 rocm_v6 cpu cpu_avx cpu_avx2 cuda_v11 rocm_v5
OLLAMA_KEEP_ALIVE 模型在显存内加载的时间，默认为 5 分钟
OLLAMA_GPU_OVERHEAD 单独为每个 GPU 预留的 VRAM ，单位是字节

	}
	return ret
}

可以使用 ollama serve -h 查看官方明确支持的环境变量。

ollama serve -h  
Start ollama  
  
Usage:  
 ollama serve [flags]  
  
Aliases:  
 serve, start  
  
Flags:  
 -h, --help   help for serve  
  
Environment Variables:  
     OLLAMA_DEBUG               Show additional debug information (e.g. OLLAMA_DEBUG=1)  
     OLLAMA_HOST                IP Address for the ollama server (default 127.0.0.1:11434)  
     OLLAMA_KEEP_ALIVE          The duration that models stay loaded in memory (default "5m")  
     OLLAMA_MAX_LOADED_MODELS   Maximum number of loaded models per GPU  
     OLLAMA_MAX_QUEUE           Maximum number of queued requests

     OLLAMA_GPU_OVERHEAD        Reserve a portion of VRAM per GPU (bytes)  
     OLLAMA_LOAD_TIMEOUT        How long to allow model loads to stall before giving up (default "5m")

切换 Ollama 的模型文件位置

OLLAMA_MODELS 环境变量可以修改模型文件下载的位置。

先把选择下载的模型文件移动到新创建的 /mnt/disk , 默认存在的位置是 ~/.ollama/models
（使用 Ollama 官方的脚本安装，默认路径是 /usr/share/ollama/.ollama/）

mv ~/.ollama/ /mnt/disk/
ln -s /mnt/disk/.ollama ~/.ollama

重新 Ollama 启动测试

NVIDIA_VISIBLE_DEVICES=all CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 OLLAMA_ORIGINS=* OLLAMA_NUM_PARALLEL=16 OLLAMA_KEEP_ALIVE=10m ollama serve

测试成功。

root@pm-65c50001:~# ollama run llama3:8b-instruct-fp16  
>>> hi  
Hi! It's nice to meet you. Is there something I can help you with or would you like to chat?

研究 Ollama mutlple GPU

在 https://github.com/ollama/ollama/issues/4198 中发现一些比较重要的环境变量。

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

[Service]  
Environment="OLLAMA_HOST=0.0.0.0:11434"  
Environment="OLLAMA_ORIGINS='*'"  
Environment="OLLAMA_MODELS=/ollama/ollama/models"  
Environment="OLLAMA_KEEP_ALIVE=10m"  
Environment="OLLAMA_NUM_PARALLEL=4"
Environment="OLLAMA_MAX_LOADED_MODELS=2"  
Environment="CUDA_VISIBLE_DEVICES=0,1,2,3"  
ExecStart=/usr/local/bin/ollama serve  
User=ollama  
Group=ollama  
Restart=always  
RestartSec=3  
Environment="PATH=/root/.local/bin:/root/bin:/usr/lib64/ccache:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin"

[Install]  
WantedBy=default.target

综合一下，决定使用下面的命令行：

NVIDIA_VISIBLE_DEVICES=all CUDA_VISIBLE_DEVICES=0,1,2,3,4,5,6,7 OLLAMA_ORIGINS=* OLLAMA_NUM_PARALLEL=16 OLLAMA_KEEP_ALIVE=10m ollama serve

如何判断模型是否加载入 GPU

ollama ps
NAME      	ID          	SIZE 	PROCESSOR	UNTIL
llama3:70b	bcfb190ca3a7	42 GB	100% GPU 	4 minutes from now

48%/52% CPU/GPU 类似这样的显示，说明模型只有部分加载入 GPU，还有一部分加载入系统的内存

内核设置 numa_balancing

Ollama 0.3.6 加载 Llama 3.1 405b 失败，界面一直卡着不动，在 Github 上看到类似问题。

https://github.com/ollama/ollama/issues/6425

WARNING: /proc/sys/kernel/numa_balancing is enabled, this has been observed to impair performance

上面的 Issue 提到有影响，手工禁用并使用 Ollama 0.3.8 可以解决问题。

echo 0 > /proc/sys/kernel/numa_balancing  # or
sysctl -w kernel.numa_balancing=0

学习 /numa_balancing 的作用，看上去像优化内存使用。
https://docs.kernel.org/admin-guide/sysctl/kernel.html#numa-balancing

Enables/disables and configures automatic page fault based NUMA memory balancing

Ollama 从 0.37 开始不再是一个独立的 X86_64 的 elf，而是一个 tar.gz
https://github.com/ollama/ollama/releases/download/v0.3.8/ollama-linux-amd64.tgz

# cd root

34s 后，Llama3.1 405b 成功启动
