国内网络在Ubuntu 22.04中在线安装Ollama并配置Open-Webui&Dify

配置docker科技网络

登录后复制

创建或编辑 Docker 配置文件 让docker使用代理：
sudo mkdir /etc/systemd/system/docker.service.d -p
sudo vim /etc/systemd/system/docker.service.d/http-proxy.conf 文件，并添加以下内容：
[Service]
Environment="HTTP_PROXY=http://10.10.9.232:30809"
Environment="HTTPS_PROXY=http://10.10.9.232:30809"
Environment="NO_PROXY=localhost,127.0.0.1"

重新加载 systemd 配置并重启 Docker 服务：
sudo systemctl daemon-reload
sudo systemctl restart docker

验证配置是否生效
sudo systemctl show --property=Environment docker

Ubuntu 22.04 安装 Docker

登录后复制

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
systemctl enable --now docker

安装 docker-compose

登录后复制

curl -L https://github.com/docker/compose/releases/download/v2.20.3/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

验证安装

登录后复制

docker -v
docker-compose -v

Ubuntu 22.04 安装ollama

在开始之前必须具备科技网络，然后安装并配置好proxychains
配置好proxychains工具之后，将在线安装脚本的所有curl命令前面增加命令：proxychains
然后正常执行安装脚本，期间保证科技网络能够使用，没有意外的话即可在线安装成功。

在线安装ollama

登录后复制

国内，安装因为速度太慢而超时安装不了，所以，将安装脚本下载下来，走代理安装
wget https://ollama.com/install.sh
chmod +x install.sh

或者
curl -fsSL https://ollama.com/install.sh -o ollama_install.sh
chmod +x ollama_install.sh

或者
curl -O https://ollama.com/install.sh
chmod +x install.sh

Use "ollama [command] --help" for more information about a command.

安装模型报错问题

登录后复制

Error: could not connect to ollama app, is it running?

经过查询，发现是需要先启动ollama app，启动方式是：sudo ollama serve

上述启动是一个交互式的形式，可以使用screen命令，进入此空间后再执行。
上述执行完成之后就可以下载模型了。
https://github.com/ollama/ollama

最终效果

使用docker安装Open-Webui

官方文档

登录后复制

官方：
sudo 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

自定义安装将3000端口改为80端口
docker run -d -p 80:8080 --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

经过测试上述操作，虽然open-webui成功启动，但是无法识别本地安装的ollama模型，所以需要使用以下方式启动

登录后复制

sudo docker run -d --network=host -e OLLAMA_BASE_URL=http://127.0.0.1:11434 -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main

效果展示

Docker搭建Dify

克隆 Dify 源代码至本地环境。git clone https://github.com/langgenius/dify.git
进入 Dify 源代码的 Docker 目录cd dify/docker
复制环境配置文件cp .env.example .env
启动 Docker 容器

根据你系统上的 Docker Compose 版本，选择合适的命令来启动容器。你可以通过 $ docker compose version 命令检查版本，详细说明请参考 Docker 官方文档：
如果版本是 Docker Compose V2，使用以下命令：docker compose up -d
如果版本是 Docker Compose V1，使用以下命令：docker-compose up -d
最后检查是否所有容器都正常运行：docker compose ps
参考：
https://docs.dify.ai/zh-hans/getting-started/install-self-hosted/docker-compose
上述完成之后，正常访问部署到服务器的IP地址，然后会让你初始化设置账户和密码，然后登录进去下面是登录进去的效果。

在Dify中加载Ollama

这里刚开始踩了坑，就是默认情况下新版本的Ollama安装成功之后就是以Systemd服务的形式启动，而这个刚开始我没仔细看，导致自己也手动使用ollama serve启动了服务，这样导致互相混淆了，最终导致的结果就是我无论怎么配置加载，在Dify中都无法查看到Ollama所加载的模型。
解决办法就是我关停了自己使用ollama serve启动的服务，然后使用Systemd形式进行管理配置服务，并且配置侦听所有IP地址。
由于上述的操作，导致对应下载的模型路径不对，所以需要更改模型的路径。

需要添加到Systemd的配置参数

sudo vim /etc/systemd/system/ollama.service

登录后复制

Environment="OLLAMA_HOST=0.0.0.0"
Environment="OLLAMA_MODELS=/home/viadmin/.ollama/models"

最终的配置结果
