搭建说明
采用官方提供apt-mirror方式进行搭建
由于单个发行版apt包磁盘占用600G左右，建议1T磁盘空间
部署环境
| 名称 | ip | 主机名 | 配置 | 操作系统 |
|---|---|---|---|---|
| apt内网源服务器 | 192.168.0.201 | CT1 | 1C 2G 1T | Ubuntu 20.04 LTS |
| 内网客户端 | 192.168.0.202 | CT2 | 1C 1G 50G | Ubuntu 20.04 LTS |
阿里云apt同步源
国内apt下载下载较慢，设置阿里云apt同步源
备份 sources.list
cp /etc/apt/sources.list /etc/apt/sources.list-bak
Ubuntu 20.04 LTS 配置修改如下
cat > /etc/apt/sources.list <<EOF

apt-mirror安装
安装
更新apt 索引与安装
apt update
apt install apt-mirror -y
配置文件
apt-mirror默认配置文件： /etc/apt/mirror.list
修改默认路径： （可选，目录可不创建）
set base_path /data/apt-mirror
set run_postmirror 0
使用阿里云apt同步源 （若多次同步失败建议切换清华大学apt源：mirrors.tuna.tsinghua.edu.cn 进行同步）
可以设置多个，当前同步focal版本
vim /etc/apt/mirror.list
############# config ##################

运行同步
apt-mirror
等待执行完毕（首次执行耗时较长，可放入后台执行）
目录结构
同步目录结构如下
mirror目录中包含了同步源的名称
root@CT1:/data/apt-mirror# ll mirror/
total 0
drwxr-x--- 3 root root 32 Jun 9 16:08 ./
drwxr-xr-x 5 root root 87 Jun 9 23:20 ../
drwxr-x--- 3 root root 20 Jun 9 16:08 mirrors.aliyun.com/
需要代理的目录为当前同步源下/ubuntu目录
root@CT1:/data/apt-mirror# ll mirror/mirrors.aliyun.com/ubuntu/
total 0
drwxr-x--- 4 root root 31 Jun 9 18:36 ./
drwxr-x--- 3 root root 20 Jun 9 16:08 ../
drwxr-x--- 6 root root 85 Jun 9 18:36 dists/
drwxr-x--- 6 root root 70 Jun 9 18:09 pool/
代理访问
配置
使用nginx docker-compose方式进行代理
安装docker与docker-compose，也可使用apt方式安装nginx
vim docker-compose.yaml
version: '3'
services:
apt-mirror:
image: nginx:1.24.0-alpine
container_name: apt-mirror
restart: always
ports:
- '80:80'
volumes:
- /data/apt-mirror/mirror/mirrors.aliyun.com/ubuntu:/usr/share/nginx/html
启动
docker-compose up -d
客户机验证
配置
配置内网主机使用搭建的apt源进行更新
备份 sources.list
cp /etc/apt/sources.list /etc/apt/sources.list-bak
修改配置

报错处理
apt源缺少cnf下的一些索引文件，导致更新失败
经查找ubuntu官网apt-mirror软件包信息，apt-mirror_0.5.4-2已修复该问题
官网下载连接：https://packages.ubuntu.com/zh-tw/mantic/all/apt-mirror/download
回到apt内网源服务器
查看当前安装包版本
root@CT1:~# dpkg -l|grep apt-mirror
ii apt-mirror 0.5.4-1 all APT sources mirroring tool
安装apt-mirror_0.5.4-2版本
使用阿里云仓库下载：
wget https://mirrors.aliyun.com/ubuntu/pool/universe/a/apt-mirror/apt-mirror_0.5.4-2_all.deb
安装
dpkg -i apt-mirror_0.5.4-2_all.deb
执行apt-mirror进行同步文章来源：https://uudwc.com/A/zkv5g
apt-mirror
apt内网源服务器更新完毕后，在apt客户端再次进行更新，提示成功文章来源地址https://uudwc.com/A/zkv5g
apt update
