ubuntu22.04.5本地apt源部署

很多情况下，内网服务器无法连接互联网，这样如果原始系统只是最基本的下载安装包，因为存在依赖包不全的情况，难以对其进行更新及通过apt安装包
所以为解决不能联网的问题，首先先通过可以联网的机器制造好源，再通过存储介质传输到无互联网的环境就解决了。
首先，先在为了下载网速快一些可连接互联网的机器配置阿里源

该方法比较灵活，不需要把镜像源所有的镜像都拉下来，只需要设置自己想要的包就可以

可以连接互联网的机器操作

修改/etc/apt/source.list

运行下面的shell

chmod +x OfflineBuild.sh
./OfflineBuild.sh common

注：common为常用包，也可以在脚本的PACKAGES加入自己需要的包名

#!/bin/bash
# 包名称

脚本运行后,会生成OfflineLoad.sh及一个iso文件将其复制到离线设备,运行OfflineLoad.sh

无法连接互联网的机器操作

chmod +x ./OffinelLoad.sh
./OfflineLoad.sh

注：该文件与上步生成的ubuntu_22.04-common.iso
OfflineLoad.sh基本上如下：

#!/bin/bash
mkdir /mnt/local-repo
mount -o loop ubuntu_22.04-common.iso /mnt/local-repo
mv /etc/apt/sources.list /etc/apt/sources.list.bak
bash -c 'echo "deb [trusted=yes] file:///mnt/local-repo stable main"' > /etc/apt/sources.list
apt-get update -y
