Arch Linux Installation Guide

Pre-installation

Set the keyboard layout

loadkeys br-abnt2

setfont Lat2-Terminus16

Connect to the internet

  • DHCP

Wired network connection and access to a DHCP server (eg: router). This option starts automatically.

dhcpcd
  • Wired

Before starting the configuration it is necessary to deactivate dhcp

systemctl stop dhcpcd.service

Identify the network interface

ip link

Enable the network interface, for example, to eth0:

ip link set eth0 up
  • WI-FI
rfkill unblock wifi
wifi-menu

Choose the network and enter your password.

Finally, test the network with:

ping -c 3 www.google.com

Partition the disks

cfdisk /dev/sda  (ou cfdisk/dev/sda)
  • Obs: Do the same with cfdisk / dev / sdb according to partitions

Example layouts:

sda1 - 512M     - EF00 - /boot
sda2 - 4G	- 8200 - /swap
sda3 - 40G      - 8300 - /root
sda4 - ~G 	- 8300 - /home	(replace ~ to remainder of the device)

Format the partitions

mkfs.fat -F32 /dev/sda1

mkfs.ext4 /dev/sda3

mkfs.ext4 /dev/sda4

Mount the file systems

To view the current partitioning layout:

lsblk /dev/sda

Mount the partitions in this order:

mount /dev/sda3 /mnt

mkdir /mnt/boot && mount /dev/sda1 /mnt/boot

mkswap -L swap /dev/sda2 && swapon /dev/sda2

mkdir /mnt/home && mount /dev/sda4 /mnt/home

Installation

Select the mirrors

mv /etc/pacman.d/mirrorlist /etc/pacman.d/mirrorlist.new

vi /etc/pacman.d/mirrorlist.new

:%s/^Server/#Server/g

/\.br

Use x to uncomment (remove the # before the server where you have Brazil). Use n to jump to another mirror. To exit ESC and type: :wq

Then:

mv /etc/pacman.d/mirrorlist.new /etc/pacman.d/mirrorlist

Install the base packages

pacstrap /mnt base base-devel

Configure the system

Fstab

genfstab -U -p /mnt >> /mnt/etc/fstab

Change root into the new system:

arch-chroot /mnt

Terminal font and keyboard

If you changed the keyboard map at the beginning of the installation process, reload that configuration again because your environment has changed:

loadkeys br-abnt2

setfont Lat2-Terminus16

If you want keyboard and font changes to persist after restarting, edit the vconsole.conf file:

nano /etc/vconsole.conf

Write it:

KEYMAP=br-abnt2
FONT=Lat2-Terminus16
FONT_MAP=

Localization

rm /etc/localtime
ln -s /usr/share/zoneinfo/America/Bahia /etc/localtime

vi /etc/locale.gen

Uncomment the language you are going to use (en_US.UTF-8 UTF-8)

/en_US

Or (pt_BR.UTF-8 UTF-8)

/pt_BR

Press x to uncomment. To exit, press ESC and type:

:wq

Then:

locale-gen

echo LANG=en_US.UTF-8 > /etc/locale.conf

export LANG=en_US.UTF-8

Or

locale-gen

echo LANG=pt_BR.UTF-8 > /etc/locale.conf

export LANG=pt_BR.UTF-8

Initramfs

mkinitcpio -p linux

Root password

Set the root password:

passwd

Add a regular user

useradd -c "MyName" -m -d /home/myname myname
  • Note: Replace MyName with the user name with uppercase and with quotation marks and myname by the system user, that is, login.

And now create the user password

passwd myname

Boot loader

Install systemd-boot:

bootctl install

Create a boot entry in /boot/loader/entries/arch.conf, replacing /dev/sda3 with a root partition:

nano /boot/loader/entries/arch.conf

It should look like this:

title          Arch Linux
linux          /vmlinuz-linux
initrd         /cpu_manufacturer-ucode.img
initrd         /initramfs-linux.img
options        root=/dev/sda3 rw

Replace cpu_manufacturer-ucode.img with intel-ucode.img or amd-ucode, depending on your processor.

  • Note: If your processor is not Intel or AMD, remove the initrd cpu_manufacturer-ucode.img

Modify /boot/loader/loader.conf to select the input default suffix:

nano /boot/loader/loader.conf

It should look like this:

timeout 3
default arch

If your processor is Intel, also install the package below that enables you to load the manufacturer's microcode at boot time

pacman -S intel-ucode

If your processor is AMD, also install the package below that enables you to load the manufacturer's microcode at boot time

pacman -S amd-ucode

Install sudo


pacman -S sudo

Open the sudoers file


nano /etc/sudoers

And uncomment the option (removing #)


# %wheel ALL=(ALL) ALL

And add, on the bottom line:


myname ALL=(ALL) ALL
  • Note: change myname by name

Save and exit the file with Ctrl + x.

Enable multilib


nano /etc/pacman.conf

Scroll down to where the multilib is and remove the # from the lines below:


#[multilib]
#Include = /etc/pacman.d/mirrorlist

Save and exit with Ctrl + x.

Enable AUR packages

Open pacman.conf


nano /etc/pacman.conf

Scroll down to the end of the file and add


[archlinuxfr]
SigLevel = Never
Server = http://repo.archlinux.fr/$arch

Save and exit with Ctrl + x.

Network configuration

Create the hostname file:

echo myhostname > /etc/hostname
  • Note: change myhostname to whatever you want

Add matching entries to hosts:

nano /etc/hosts

It should look like this:

127.0.0.1	localhost
::1		localhost
127.0.1.1	myhostname.localdomain	myhostname
  • Note: change myhostname to whatever you want

Install the necessary packages for the network to work:

pacman -Sy wireless_tools
pacman -Sy wpa_supplicant
pacman -Sy dialog
pacman -Sy networkmanager

systemctl enable NetworkManager

systemctl enable NetworkManager.service

systemctl enable wpa_supplicant.service

Disable dhcp:

systemctl disable dhcpcd.service

systemctl disable dhcpcd@.service

Finishing the system installation

Unmount the partitions and restart with:

exit

umount -R /mnt

reboot

Remove the installation media.
