# Arch Linux Installation & Configuration ## Pre-installation Verify the boot mode ``` # ls /sys/firmware/efi/efivars ``` Connect to the internet ``` # iwctl ``` Update the system clock ``` # timedatectl set-ntp true ``` Partition the disks ``` # gdisk /dev/sda ``` |Partition |Partition type |Size | |---------------------------|---------------------|-----------------------| |`/dev/efi_system_partition`|EFI system partition |550MiB | |`/dev/swap_partition` |Linux swap |2GiB | |`/dev/root_partition` |Linux x86-64 root (/)|Remainder of the device| Format the partitions ``` # mkfs.ext4 /dev/root_partition # mkswap /dev/swap_partition # mkfs.fat -F 32 /dev/efi_system_partition ``` Mount the file systems ``` # mount /dev/root_partition /mnt # mount --mkdir /dev/efi_system_partition /mnt/boot # swapon /dev/swap_partition ``` ## Installation Add mirrors to `/etc/pacman.d/mirrorlist`. ``` Server = https://archlinux.cs.nycu.edu.tw/$repo/os/$arch Server = https://shadow.ind.ntou.edu.tw/archlinux/$repo/os/$arch Server = https://mirror.archlinux.tw/ArchLinux/$repo/os/$arch ``` Install packages (only `base` `linux` `linux-firmware` are essential) ``` # pacstrap /mnt base linux linux-firmware vi sudo networkmanager git xmonad xmonad-contrib xorg-server xorg-xinit rxvt-unicode intel-ucode firefox adobe-source-han-sans-otc-fonts fcitx5-im fcitx5-chewing ``` ## Configuration Fstab ``` # genfstab -U /mnt >> /mnt/etc/fstab ``` Chroot ``` # arch-chroot /mnt ``` Time zone ``` # ln -sf /usr/share/zoneinfo/Asia/Taipei /etc/localtime # hwclock --systohc ``` ### Localization Edit `/etc/locale.gen` and uncomment `en_US.UTF-8 UTF-8` and needed locales. Generate the locales by running: ``` # locale-gen ``` Create the `locale.conf` file, and set the LANG variable: ``` (/etc/locale.conf) LANG=en_US.UTF-8 ``` ### Network configuration ``` /etc/hostname ------------- myhostname ``` ``` /etc/hosts --------------------------- 127.0.0.1 localhost ::1 localhost 127.0.1.1 myhostname ``` Root password ``` # passwd ``` Boot loader ``` # bootctl install ``` run `blkid /dev/root_partition` to get the number after `PARTUUID="`. ``` # vi /boot/loader/entries/arch.conf ``` ``` /boot/loader/entries/arch.conf ----------------------------------- title Arch Linux linux /vmlinuz-linux initrd /intel-ucode.img initrd /initramfs-linux.img options root=PARTUUID=your_partuuid_code ``` ``` # vi /boot/loader/loader.conf ``` ``` /boot/loader/loader.conf ------------------------ default arch.conf timeout 0 console-mode max editor no ``` ### Reboot Exit the chroot environment by pressing `Ctrl+d`. ``` # umount -R /mnt # reboot ``` Add user ``` # useradd -m -G wheel user_name # passwd user_name ``` Add user to sudoers ``` # visudo ``` Uncomment the line of `# %wheel ALL=(ALL:ALL) ALL`
