Ollama安装

1.下载Ollama

1 2	`Linux系统的安装命令如下： curl -fsSL https://ollama.com/install.sh \| sh`

2.下载慢，使用这个脚本ollama_install.sh

给脚本添加执行权限
chmod +x ollama_install.sh
运行修改后的脚本
sudo ./ollama_install.sh

3.以下是ollama_install.sh 脚本

#!/bin/sh
# This script installs Ollama on Linux.
# It detects the current operating system architecture and installs the appropriate version of Ollama.

4.下载llama3模型

1	`ollama run llama3`

5.配置服务

为使外网环境能够访问到服务，需要对HOST进行配置。
打开配置文件：vi /etc/systemd/system/ollama.service，根据情况修改变量Environment：
服务器环境下：Environment="OLLAMA_HOST=0.0.0.0:11434"
虚拟机环境下（推荐）：Environment="OLLAMA_HOST=服务器内网IP地址:11434"

6.启动 Ollama

使用 systemd 启动 Ollama：
sudo systemctl daemon-reload
sudo systemctl start ollama
sudo systemctl restart ollama

7.在外网环境验证连接

1
2

方法一：执行curl http://ip:11434命令，若返回“Ollama is running”，则表示连接正常。
方法二：在浏览器访问http://ip:11434，若页面显示文本“Ollama is running”，则表示连接正常。

8.下载Open WebUI

Open WebUI基于docker部署，docker的安装方法可以参考这篇知乎文章。
Open WebUI既可以部署在服务端，也可以部署在客户端：
# 若部署在客户端，执行：
docker run -d -p 3000:8080 --add-host=host.docker.internal:host-gateway -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main

# 若部署在服务端，执行：(推荐)
docker run -d -p 3000:8080 -e OLLAMA_BASE_URL=http://192.168.0.214:11434 -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main

9.检查相关配置

下载完之后，就可以在浏览器访问了，地址为http://loacalhost:3000（客户端部署）或http://服务器ip:3000。

页面加载完成后（这个过程可能需要一些时间），新注册一个账号并登录。

登录之后，点击页面顶端的齿轮⚙图标进入设置：

侧边导航栏-General，将语言设置为中文
侧边导航栏-模型，一般会自动拉取ollama服务上部署好的模型，可选模型参看官方的这篇文档
https://ollama.com/library

10.选择模型

1	`在顶端下拉框选择好模型，就可以开始提问啦！`
