archLinux基本配置

时间设置

$ timedatectl status
...
NTP service: active
...

如果上面NTP service的状态不是 active，执行下需的开启命令

$ sudo timedatectl set-ntp true

如果时间不是中国的，执行下面的命令

$ sudo timedatectl set-timezone Asia/Shanghai

查看

$ ls -l /etc/localtime
lrwxrwxrwx 1 root root 33 7月21日 12:22 /etc/localtime -> /usr/share/zoneinfo/Asia/Shanghai

如果不正确

$ ln -sf /usr/share/zoneinfo/Region（地区名）/City（城市名） /etc/localtime

获取镜像列表
https://wiki.archlinuxcn.org/wiki/%E9%95%9C%E5%83%8F%E6%BA%90

$ curl -o /etc/pacman.d/mirrorlist https://archlinux.org/mirrorlist/all/

更换国内源

$ curl -s "https://archlinux.org/mirrorlist/?country=CN&protocol=https&use_mirror_status=on" | sed -e 's/^#Server/Server/' -e '/^#/d' | tee mirrorlist

$ sudo mv /etc/pacman.d/mirrorlist /etc/pacman.d/mirrorlist.old
$ sudo cp mirrorlist /etc/pacman.d/

$ sudo pacman -Syy

如果安装了 pacman-contrib 可以用 rankmirrors 进行连接速度的排序，安装需要90多MiB的空间
----------------------------------------------------------------
安装命令行编辑器nano,主要是vi 不到1 MiB 但不好用，vim要130以上的MiB空间

$ sudo pacman -S nano

设置语言

参考 - https://wiki.archlinux.org/title/Localization/Simplified_Chinese

https://wiki.archlinuxcn.org/wiki/Locale#%E5%9C%A8%E7%94%A8%E6%88%B7%E4%BC%9A%E8%AF%9D%E4%B8%AD%E8%A6%86%E7%9B%96%E7%B3%BB%E7%BB%9F%E5%8C%BA%E5%9F%9F%E8%AE%BE%E7%BD%AE

本地化 Locale

$ sudo nano /etc/locale.gen

找到（ctrl + w）去掉以下三项的注释

en_US.UTF-8 UTF-8
zh_CN.UTF-8 UTF-8
zh_TW.UTF-8 UTF-8

保存（ctrl + o）
退出（ctrl + x)
生成locale本地化文件

$ sudo locale-gen
Generating locales...
en_US.UTF-8... done
zh_CN.UTF-8... done
zh_TW.UTF-8... done

创建全局本地化选项 缺省是：C.UTF8
LANG：默认的区域设置,这个变量的值会覆盖掉所有未设置的 LC_* 变量的值，设置为en_US.UTF-8 是防止tty 乱码(garbled)，如果要正确显示中文，建议安装zhcon

$ echo 'LANG=en_US.UTF-8' |sudo tee /etc/locale.conf

新设置会在下次登录生效，需要立即生效执行：

$ unset LANG
$ source /etc/profile.d/locale.sh

安装中文字体，wqy-microhei 是最小的字库：

$ sudo pacman -S wqy-microhei

LANGUAGE：后备区域设置，推荐在 ~/.xinitrc 等用户自己的环境中使用

export LANG=zh_CN.UTF-8
export LANGUAGE=zh_CN:en_US:en
