如何优化国内Debian服务器（仅限于站长）

操作系统： Debian 11 Core

第一件事，换源。

众所周知，Debian默认的源在国内是真的慢，为了防止太慢耽误时间，所以我们要把它换成腾讯源，代码如下：

vim /etc/apt/sources.list

然后把内容替换成：

deb https://mirrors.tencent.com/debian/ bullseye main non-free contrib
# deb-src https://mirrors.tencent.com/debian/ bullseye main non-free contrib
deb https://mirrors.tencent.com/debian-security/ bullseye-security main
# deb-src https://mirrors.tencent.com/debian-security/ bullseye-security main
deb https://mirrors.tencent.com/debian/ bullseye-updates main non-free contrib
# deb-src https://mirrors.tencent.com/debian/ bullseye-updates main non-free contrib
deb https://mirrors.tencent.com/debian/ bullseye-backports main non-free contrib
# deb-src https://mirrors.tencent.com/debian/ bullseye-backports main non-free contrib

最后执行：

apt update -y

第二件事，修改 ~/.vimrc

众所周知，vim这玩意编辑中文会乱码，为了防止它乱码导致我没兴趣改，所以我们要编辑 ~/.vimrc让他支持中文：

set termencoding=utf-8
set encoding=utf8
set fileencodings=utf8,ucs-bom,gbk,cp936,gb2312,gb18030
