Debian12换镜像源

0 背景

用docker运行了一个node容器，发现连vim也没有，所以打算安一个vim

1 查看操作系统

find / -name '*release*' #查看release信息

2 更换镜像源

2.1 从网上找个国内镜像源

确定好操作系统版本后，从网上搜一下对应的数据源。这里提供一个清华的源

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free
 
deb https://mirrors.tuna.tsinghua.edu.cn/debian-security/ buster/updates main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security/ buster/updates main contrib non-free
 
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free
 
deb https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free

2.2 写入配置文件

切换目录到/etc/apt下
因为没有vim，不能直接复制粘贴，所以可以用重定向写入source.list

echo 'deb https://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster main contrib non-free

deb https://mirrors.tuna.tsinghua.edu.cn/debian-security/ buster/updates main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian-security/ buster/updates main contrib non-free

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-updates main contrib non-free

deb https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free
deb-src https://mirrors.tuna.tsinghua.edu.cn/debian/ buster-backports main contrib non-free' > sources.list

2.3 更新

apt-get update

注：这样镜像源就换好了，如果你发现还是有国外的源在更新，可以把原来的文件名改掉（sources.list.d文件夹下的文件随便加个后缀就行）

3 后记

如果你安装vim发现报错，vim-common版本有问题之类的报错，可以参考这个文章
