洛衣博客 记载WSL2上Debian的安装过程和一些常用优化配置，带来流畅的使用体验。
WSL2安装Debian
待更新。
WSL2上Debian的优化配置
设置使用 sudo 时免输密码
每次使用 sudo 时都需要输入密码确实烦人, 毕竟是私人电脑, 安全性有锁屏密码保护就可以了, 为了使用方便, 不仿取消使用 sudo 时需要输入 root 用户密码的设定:
打开终端, 输入 sudo vi /etc/sudoers , 在打开的文件中, 将
%sudo ALL=(ALL:ALL) ALL改为：
%sudo ALL=(ALL:ALL) NOPASSWD:ALL即可。
更换国内软件源
编辑软件源列表
软件源配置保存在/etc/apt/sources.list中，打开以修改。
sudo vim /etc/apt/sources.list按i插入，使用鼠标或方向键控制光标删除原有软件源，并任选以下源写入。个人认为中科大源库较全面，速度较快。

更新软件源列表
sudo apt-get update
sudo apt-get upgrade显示更多字符：安装自定义字体文件
美化终端提示信息或查看特定文件可能需要系统显示更多的字符。
下载字体
可以下载一整个字体包，包含多种样式。
字体生效
将字体包文件夹移动到/usr/share/fonts
cp -r {font_dir_path} /usr/share/fonts/{certain_dir} //按实际情况填入更新字体缓存
cd /usr/share/fonts
sudo apt-get install fontconfig
fc-cache -fv查看字体列表
fc-list重启终端即生效。
