Debian系统配置中文语言及环境

Debian配置系统中文语言及环境

1，安装语言包 sudo apt install locales

2，配置语言环境 sudo dpkg-reconfigure locales

按下空格即可选择，前面带星号(*)即被选中，通常不需要全部选择安装，选择需要的即可。

3，locale命令基本使用

查看已经安装的语言环境：locale -a

查看当前系统语言环境变量配置： locale

4，临时改变语言环境 export LANG=C.UTF-8

5，永久改变当前用户语言环境

编辑 ~/.bashrc ,以及~/.profile 在.bashrc以及~/.profile文件末尾加入 

export LANG=zh_CN.utf8 即可

**補充
~/.bashrc和~/.profile（仅对当前用户生效）
**

# 例如
echo "export LC_ALL=en_US.UTF-8" >> ~/.bashrc
echo "export LANG=en_US.UTF-8" >> ~/.bashrc
echo "export LANGUAGE=en_US.UTF-8" >> ~/.bashrc

echo "export LANG=zh_TW.UTF-8" >> ~/.profile
echo "export LANGUAGE=zh_TW:zh:zh_CN:zh:en_US:en" >> ~/.profile
echo "export LC_ALL=zh_TW.UTF-8" >> ~/.profile

zh_CN:zh:en_US:en


再來
source ~/.bashrc 即可生效

也可以重新開機。

中文字型的問題

 

 Debian 10系列 提供 Google 思源字體套件 (fonts-noto 等系列套件) 。安裝桌面環境時，就會順便安裝思源字體。文泉驛 (fonts-wqy) 和文鼎字體 (ttf-arphic) 不再是中文桌面環境所需字體套件。視個人需要安裝。

    xfonts-wqy : 文泉驛 X11 字體。
    fonts-wqy-zenhei : 文泉驛正黑體 (TrueType)。套件舊名 ttf-wqy-zenhei 。
    fonts-wqy-microhei : 文泉驛微米黑體 (TrueType)。套件舊名 ttf-wqy-microhei 。
    fonts-arphic-ukai : 文鼎楷書體 (TrueType)。套件舊名 ttf-arphic-ukai 。
    fonts-arphic-uming : 文鼎明體 (TrueType) 。套件舊名 ttf-arphic-uming 。
    fonts-noto : Google 思源字體 (Debian 10)。

 fonts-noto-cjk-extra/stable,stable 1:20220127+repack1-1 all
fonts-noto-cjk/stable,stable,now 1:20220127+repack1-1 all 

這兩個可以安裝 fonts-noto-cjk 系列
