Ubuntu20.04搭建本地镜像服务器

• 安装镜像下载工具

#更新安装
apt update
apt install apt-mirror

• 修改配置文件来更改下载源

vim /etc/apt/mirror.list

mirror.list

############# config ##################
#
# set base_path /var/spool/apt-mirror

# set cleanscript $var_path/clean.sh
# set defaultarch <running host architecture>

deb http://cn.archive.ubuntu.com/ubuntu focal main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu focal-security main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu focal-updates main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu focal-proposed main restricted universe multiverse
deb http://cn.archive.ubuntu.com/ubuntu focal-backports main restricted universe multiverse
 
clean http://cn.archive.ubuntu.com/ubuntu

这里的 focal 是当前系统的版本代号

• 配置完后下载镜像文件 (大约150GB)

#运行下载,以后更新也可以运行这个指令
apt-mirror

下载完毕后,所有的文件在/var/spool/apt-mirror/mirror/cn.archive.ubuntu.com/ubuntu/目录下

• 外部网络访问

#安装apache2
apt install apache2

#在/var/www/html中创建软连接
ln -s /var/spool/apt-mirror/mirror/cn.archive.ubuntu.com/ubuntu/ /var/www/html/ubuntu

#启动服务
systemctl start apache2

访问http://[host]:[port]/ubuntu查看是否成功

• 修改apt源

#备份
cp /etc/apt/sources.list /etc/apt/sources.list.bak

#修改
vim /etc/apt/sources.list

#更新
apt update

sources.list

deb http://192.168.200.154:50002/ubuntu focal-security universe
deb http://192.168.200.154:50002/ubuntu focal-security multiverse

以上步骤操作完后,执行apt update会有报错,因为这个apt-mirror没有维护并且有几个错误，新版本缺少文件。

解决办法:拉取 https://github.com/Stifler6996/apt-mirror ,并将apt-mirror替换掉/usr/bin内的apt-mirror

最后重新执行apt-mirror即可
