Arch Linux is a general-purpose Linux distribution for x86-64 computers and is very popular among the intermediate and advanced Linux users. Arch Linux project is purely driven by the community and the core development circle.
The design of Arch Linux’s follows KISS principle (「keep it short and simple」) as the general guidelines which mean you will only get a minimal base system from the OS installation and have to configure the system further to use it.
Arch Linux offers new packages/updates on the rolling release model, i.e., packages are provided throughout the day. Pacman (Arch Linux’s package manager) allows users to keep systems updated easily, daily.
Arch Linux has dropped support for 32bit OS from Feb 2017 and now supports only x86_64 installation.
Requirements- An x86_64 (64 bit) machine
- 512 MB of RAM
- At least 1GB of free disk space
- An Internet Connectivity
- USB flash drive or Blank CD for burning the installation image.
Here, we will see how to install Arch Linux latest version (v 2018.04.1) from USB / CD.
Arch Linux installation process requires an internet connection to retrieve packages from a remote repository.
Step 1: Download Arch LinuxDownload the latest version of Arch Linux from the official website.
Download Arch Linux Latest Version Step 2: Create a Live USB / Write a Bootable CDWe will now create a live USB / write a bootable CD from the downloaded ISO image.
Create a live USB:
Replace /path/to/archlinux.iso
with the path to the downloaded ISO file and /dev/sdx
with your USB drive name.
dd bs=4M if=/path/to/archlinux.iso of=/dev/sdx status=progress oflag=sync
Write a bootable CD:
Replace /path/to/archlinux.iso
with the path to the downloaded ISO file.
growisofs -dvd-compat -Z /dev/sr0=/home/user_name/Downloads/LinuxMint.isoStep 3: Boot from Live USB or CD
Power on your system and press F2, F10 or F12
to change/select the boot order.
To boot from Live USB, you need to select boot from USB or removable drive. To boot from CD, you need to select boot from CD/DVD ROM drive.
Once system boots from Live USB or CD, you will get an installer screen, like below.
Choose Boot Arch Linux (x86_64) and then press Enter.

Check the internet connectivity.
ifconfig ping google.com -c 2Install Arch Linux 2018 – Internet Connectivity Check
If your system does not get a reply, then configure static IP address on your system so that your system can connect to the internet to download packages.
ip addr flush dev enp0s3 ifconfig enp0s3 192.168.1.100 netmask 255.255.255.0 route add default gw 192.168.1.1 echo "nameserver 192.168.1.1" >> /etc/resolv.conf echo "nameserver 8.8.8.8" >> /etc/resolv.conf
Replace network card and IP address according to your environment.

fdisk -lInstall Arch Linux 2018 – List Hard Drives
The system has a 40GB disk (/dev/sda) and will use that disk for OS installation. The name of the disk varies depending upon the system. The disks can have other names such as vda, hda, etc.
Now, we will use fdisk command to create partitions as per the requirement.
Partition details are shown below.
/boot – 500M
swap – 4GB (Double the RAM)
/ – ~ 35 GB (Remaining Space)
fdisk /dev/sda
/boot:

Install Arch Linux 2018 – Create Root PartitionOnce you have created partitions, use p
to confirm the creation of partitions and then, w
to save the changes.
Verify parttions using the fdisk -l
command. We now have three partitions.
/dev/sda1 – /boot
/dev/sda2 – SWAP
/dev/sda3 – / (root)
Install Arch Linux 2018 – Verify Partitions Step 5: Create FilesystemNow, its time format the created partitions with the required file systems. You can format /boot (/dev/sda1) as EXT2 or EXT3, SWAP (/dev/sda2) as SWAP and / (/dev/sda3) as EXT4 filesystem.
mkfs.ext2 /dev/sda1 mkfs.ext4 /dev/sda3 mkswp /dev/sda2

Install Arch Linux 2018 – Create Filesystems Step 6: Mount PartitionsOnce you have formatted the partitions, use the mount command to mount it. /
(root) partition must be mounted on /mnt
directory. Also, you would need to initialize the swap partition.
mount /dev/sda3 /mnt swapon /dev/sda2
If you have additional partitions, then those need to be mounted on the respective directories on /mnt. For Ex: /home
partition needs to be mounted on /mnt/home
.
Now, its time to install Arch Linux base system.
pacstrap /mnt/ base base-develInstall Arch Linux 2018 – Install Arch Linux Base System
The installation will take at least 15 to 30 minutes to complete depending upon your internet speed.
Install Arch Linux 2018 – Arch Linux Installation in ProgressThe below message confirms you that the Arch Linux Installation has been completed successfully.
Install Arch Linux 2018 – Arch Linux Installation Completed Step 8: Create fstabAfter the base installation, generate the fstab file for the system using the genfstab
command.
genfstab /mnt >> /mnt/etc/fstab
Verify the fstab entries using the below command.
cat /mnt/etc/fstab

arch-chroot /mntStep 10: Set System Language
You can configure the system language by uncommenting the required languages from /etc/locale.gen
file.
vi /etc/locale.gen
Uncomment en_US.UTF-8 UTF-8 for American-English.
Install Arch Linux 2018 – System Language SelectionGenerate the locale.
locale-genInstall Arch Linux 2018 – Generate Locale
Set the system locale by placing the LANG
variable in /etc/locale.conf
file.
echo "LANG=en_US.UTF-8" > /etc/locale.confStep 11: Set Timezone
Now, configure the system time zone by creating a symlink of your timezone to /etc/localtime
file.
ln -sf /usr/share/zoneinfo/US/Central /etc/localtime
You can find the available timezones under /usr/share/zoneinfo
directory.
ls /usr/share/zoneinfoInstall Arch Linux 2018 – Timezone Details
Also, set the hardware clock to UTC.
hwclock --systohc --utcStep 12: Set Hostname
Place the system hostname in /etc/hostname
file.
echo "archlinux.itzgeek.local" > /etc/hostnameStep 13: Set root password
Use the passwd
command in the terminal to set the root password.
passwdStep 14: Install GRUB Boot Loader
Arch Linux requires boot loader to boot the system. You can install grub boot loader using the below commands.
pacman -S grub grub-install /dev/sda grub-mkconfig -o /boot/grub/grub.cfg

exit reboot

Install Arch Linux 2018 – RebootOnce the reboot is complete, you would get the Arch Linux login prompt. Log in as the root user and the password you set during the os installation (step 13).
