# ls /sys/firmware/efi/efivars
If the command shows the directory without error, then the system is booted in UEFI mode. If the directory does not exist, the system may be booted in BIOS (or CSM) mode. If the system did not boot in the mode you desired, refer to your motherboard's manual.
# efivar --list
# ip link
# ip a
# ping archlinux.org
# ping ya.ru
# timedatectl set-ntp true
# lsblk
# fdisk -l
Suppose you have a single /dev/sda disk.
-- If automated, better dd random data into it first, to erase previous partitions.
You have to create at least two partitions, EFI system partition (260+ MiB), and Linux root partition.
# fdisk /dev/sda
m
g
w
then (approximate, be careful!):
# fdisk /dev/sda
n
+300M -- 100M min
t
1
w
then (approximate, be careful!):
# fdisk /dev/sda
n
t
23
w
The result must be:
/dev/sda1 EFI system partition 300M
/dev/sda2 Linux x86-64 root the remainder
Now, make filesystems:
# mkfs.fat -F32 /dev/sda1
# mkfs.ext4 /dev/sda2
The UEFI specification mandates support for the FAT12, FAT16, and FAT32 file systems[4]. To prevent potential issues with other operating systems and also since the UEFI specification only mandates supporting FAT16 and FAT12 on removable media[5], it is recommended to use FAT32.
If you get the message WARNING: Not enough clusters for a 32 bit FAT!, reduce cluster size with mkfs.fat -s2 -F32 ... or -s1; otherwise the partition may be unreadable by UEFI. See mkfs.fat(8) for supported cluster sizes.
- The same thing, except don't create the ESP/EFI/whatever partition.
- Also, don't bother creating GPT, stick with MBR.
- Don't forget to set bootable flag to main partition.
First time, do this, in this order:
# mount /dev/sda2 /mnt
# cd /mnt
# mkdir boot
# mount /dev/sda1 boot
Next time, do this, in this order:
# mount /dev/sda2 /mnt
# mount /dev/sda1 /mnt/boot
If you created a swap partition, e.g. /dev/sda3, then you can install it too into the system:
# mkswap /dev/swap_partition
# swapon /dev/swap_partition
# pacstrap /mnt base linux linux-firmware
# pacstrap /mnt openssh rsync sudo iproute2 dhclient man-db man-pages texinfo nano socat netcat curl wget iptables nftables
Optional:
# pacstrap /mnt ddrescue diffutils ethtool hdparm nmap
# pacstrap /mnt htop wireguard-tools nodejs
Also add grub, if you're installing non-UEFI system.
dhclient is ISC dhclient, specifically.
# genfstab -U /mnt >> /mnt/etc/fstab
(!) This command must be called exactly once, or you'll need to edit the file manually.
Check the resulting /mnt/etc/fstab file, and edit it in case of errors.
The "relatime" is not a typo!
relatime updates the access time only if the previous access time was earlier than the current
modify or change time. In addition, since Linux 2.6.30, the access time is always updated if the
previous access time was more than 24 hours old. This option is used when the defaults option,
atime option (which means to use the kernel default, which is relatime; see mount(8) and
wikipedia:Stat (system call)#Criticism of atime) or no options at all are specified.
Note:
If you have several data volumes, and want them be included in fstab - please mount them
beforehand somewhere in the /mnt too.
E.g.:
sda1 /mnt
sda2 /mnt/data_volume_A
sdb1 /mnt/data_volume_B
# arch-chroot /mnt
# ln -sf /usr/share/zoneinfo/<Region>/<City> /etc/localtime
# hwclock --systohc
# echo <hostname> > /etc/hostname
Add matching entries to hosts(5):
/etc/hosts
127.0.0.1 localhost
::1 localhost
127.0.1.1 myhostname.localdomain myhostname
If the system has a permanent IP address, it should be used instead of 127.0.1.1.
# passwd
# useradd -m op1
# passwd op1
# bootctl --path=/boot install
Configure it:
# nano /boot/loader/loader.conf
timeout 3
default arch.conf
# nano /boot/loader/entries/arch.conf
title Arch Linux
linux /vmlinuz-linux
initrd /initramfs-linux.img
options root=/dev/sda2 rw
# pacman -S grub
# grub-install --target=i386-pc /dev/sdX
where /dev/sdX is the disk (not a partition) where GRUB is to be installed.
Now you must generate the main configuration file.
# grub-mkconfig -o /boot/grub/grub.cfg
# exit
# systemctl reboot
Exit the chroot environment by typing exit or pressing Ctrl+d.
Optionally manually unmount all the partitions with umount -R /mnt: this allows noticing any "busy" partitions, and finding the cause with fuser(1).
Finally, restart the machine by typing reboot: any partitions still mounted will be automatically unmounted by systemd. Remember to remove the installation medium and then login into the new system with the root account.
# systemctl enable systemd-networkd
# systemctl start systemd-networkd
# systemctl status systemd-networkd
See the list of network interfaces:
# ip a
Enable DHCP on enp1s0:
# nano /etc/systemd/network/LAN1.network
[Match]
Name=enp1s0
[Network]
DHCP=yes
Enable static IP on enp2s0:
# nano /etc/systemd/network/LAN2.network
[Match]
Name=enp2s0
[Network]
Address=10.50.0.67/8
#Gateway=10.1.10.1
#DNS=10.1.10.1
#DNS=8.8.8.8
Restart networkd:
# systemctl restart systemd-networkd
Install and start DHCP client on enp1s0:
# systemctl enable dhclient@enp1s0.servive
# systemctl start dhclient@enp1s0.servive
# systemctl status dhclient@enp1s0.servive
Check:
# ip a
While waiting for an IP to be assigned you can run something like:
# ping <some-host>
# watch -n 1 ping -c 1 archlinux.org
# pacman -S xorg firefox x11vnc nodm xterm
To test that X works, re-log as a user, then try:
$ startx
The xterm must open. Note, the keyboard works only when mouse is over the window.
TIP:
- Ctrl+Alt+F1 to terminal
- Alt-F7 back to GUI
https://wiki.archlinux.org/index.php/x11vnc
https://wiki.archlinux.org/index.php/Nodm
After installing nodm, modify the /etc/nodm.conf file. Set the NODM_USER variable to the user which should be automatically logged in, and change the NODM_XSESSION variable to point to the script that starts your session. The NODM_XSESSION script must be executable!
Enable nodm.service so nodm will be started on boot:
# systemctl enable nodm
Log in as a user, and:
$ nano .xinitrc
#! /bin/bash
firefox
$ chmod +x .xinitrc
Login session:
For proper session handling, create pam.d file with the following content:
# nano /etc/pam.d/nodm
#%PAM-1.0
auth include system-local-login
account include system-local-login
password include system-local-login
session include system-local-login
Edit the nodm.service, and add these lines:
Restart=always
RestartSec=5
(Look at /etc/systemd/system or /lib/systemd/system)
then
# systemctl daemon-reload
https://wiki.archlinux.org/index.php/OpenSSH
# pacman -S openssh
# systemctl enable sshd
# systemctl start sshd
# systemctl status sshd
Config is in the:
/etc/ssh/sshd_config
https://wiki.archlinux.org/title/KDE
# pacman -Syu plasma-meta
Optional:
# pacman -Syu kde-applications -- can be huge, take care to select what you really want
# pacman -Syu iw
Then:
# pacman -Syu networkmanager
# systemctl enable NetworkManager
# systemctl start NetworkManager
https://www.reddit.com/r/archlinux/comments/vborwi/kde_plasma_on_arch_linux_not_showing_wifi/
Then:
# systemctl enable sddm
# systemctl start sddm
# pacman -Syu git base-devel -- could've been installed in the beginning
Then for any AUR package:
$ git clone https://aur.archlinux.org/yay-bin.git
$ cd yay-bin
$ makepkg -si
If you want to use yay instead (previously installed):
$ yay -S google-chrome
