搭建私有apt镜像站

提示

本文搭建的apt镜像站只针对x86架构的Ubuntu 22.04。

安装apache2

sudo apt install -y apache2
sudo systemctl enable apache2

创建mirror数据所在目录

mkdir /home/ubuntu/mirrors
sudo chown www-data:www-data /home/ubuntu/mirrors

安装apt-mirror

sudo apt update
sudo apt install -y apt-mirror

配置apt-mirror

sudo cp /etc/apt/mirror.list /etc/apt/mirror.list-bak

mirror.list

 deb-i386 https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ jammy-backports main restricted universe multiverse

 clean https://mirrors.tuna.tsinghua.edu.cn/ubuntu/

启动mirror拉取数据

sudo apt-mirror

可以在byobu/tmux中运行，也可以丢到后台：

nohup sudo apt-mirror &
tail nohup.out

问题1

在使用apt-mirror工具下载ubuntu22镜像源导入内网后，apt-get update发现缺少dep11，cnf及binary-i386下的一些索引文件，导致更新失败，无法正常使用。这是由于apt-mirror在2017年就停止了维护更新，之后出现的ubuntu20和ubuntu22更新了仓库的索引文件，apt-mirror没有办法兼容。

方法1

创建一个脚本fix-errors.sh自动下载这些文件：

#!/bin/bash

cd /home/ubuntu/mirrors/mirror/mirrors.tuna.tsinghua.edu.cn/ubuntu/dists

for dist in jammy jammy-updates jammy-security jammy-backports; do
  for comp in main multiverse universe; do
    for size in 48 64 128; do
    wget http://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/$dist/$comp/dep11/icons-${size}x${size}@2.tar.gz -O $dist/$comp/dep11/icons-${size}x${size}@2.tar.gz;
   done
 done
done

cd /var/tmp
for p in "${1:-jammy}"{,-{security,updates,backports}}\
/{main,restricted,universe,multiverse};do >&2 echo "${p}"
#echo '-----'
#echo "http://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/${p}/cnf/Commands-amd64.xz"
wget -q -c -r -np -R "index.html*" "http://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/${p}/cnf/Commands-amd64.xz"
wget -q -c -r -np -R "index.html*" "http://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/${p}/cnf/Commands-i386.xz"
wget -q -c -r -np -R "index.html*" "http://mirrors.tuna.tsinghua.edu.cn/ubuntu/dists/${p}/binary-i386/"
done

sudo cp -av mirrors.tuna.tsinghua.edu.cn/ubuntu/ /home/ubuntu/mirrors/mirror/mirrors.tuna.tsinghua.edu.cn

方法2

修改/usr/bin/apt-mirror文件：

在add_url_to_download( $url . $_ . "/binary-" . $arch . "/Packages.xz" );下添加一行： add_url_to_download( $url . $_ . "/cnf/Commands-" . $arch . ".xz" );

注释掉：$uri =~ s/^([^@]+)?@?// if $uri =~ /@/;

问题2

如果apache出现权限问题注意2个地方

1. 将源目录的权限修改为www-data用户
2. 将www-data加入ubuntu组

创建一个contab每日同步一次mirrors

00  01  *  *  *  /usr/bin/apt-mirror

客户端
