Arch Linux Installation

Arch Linux

A Linux distro which is commonly considered for power users. It provides a lot of customisation right from the installation process. Its very light-weight distro, and it install very few core packages at the time of installation. Also one get all the latest packages as Arch Linux is rolling release distro. Also Arch users get access to Arch User Repository aka AUR which is a comprehensive repository with tons of packages. One can say that AUR contain all the packages that you can find on any other distro.

But the installation process is little complicated as you don’t get any GUI installer instead you’ve to install it from command line only. So, here’s the step by step guide to install Arch Linux on your machine.

Steps

Download the Arch Linux iso from here. Note that the iso is common for both 64 bit and 32 bit. Burn the iso into a CD or make a bootable usb from the iso downloaded and boot from it. Choose your architecture from the boot menu. Once you get to the commandline, check your internet connection.
$ ping google.com
List the disks
$ fdisk -l
Choose the disk you want to install Arch Linux in and partition it.
$ cfdisk /dev/sdx
Caution ⚠ : This will erase all the data on that disk, choose wisely. I’m using “x” in sdx, you can replace it with variable corresponding to your disk. Choose dos. Create one root partition, one swap partition, and more if you need them. Make root partition bootable and change swap partition type to Linux Swap. Write and quit. Change root partition to ext4 file system.
$ mkfs.ext4 /dev/sdx1
Change swap partition file system to swap.
$ mkswap /dev/sdx2
Mount swap partition.
$ swapon /dev/sdx2
Mount all the partition.
$ mount /dev/sdx1 /mnt
Note: Mount all other partitions if any.
Update pacman repositories.
$ pacman -Sy
Install Arch base packages.
$ pacstrap -i /mnt base base-devel
Generate fstab
$ genfstab -U -p /mnt >> /mnt/etc/fstab
$ cat /mnt/etc/fstab
Change root into the new system
$ arch-chroot /mnt
List all the regions and cities for time zone.
$ ls /usr/share/zoneinfo/
$ cd /usr/share/zoneinfo/REGION
$ ls
Update your time zone using above information
$ ln -s /usr/share/zoneinfo/REGION/CITY /etc/localtime
$ hwclock --systohc --utc
Generate locale
$ nano /etc/locale.gen
Note: Uncomment your specific localization.
$ locale-gen
$ echo LANG=en_US.UTF-8 > /etc/locale.conf
Replace en_US.UTF-8 with the one you uncommented previously.

$ echo HOSTNAME > /etc/hostname
Replace HOSTNAME with your hostname.
Set the network configuration

Create a new initial RAM disk
$ mkinitramfs -p linux
Install bootloader
$ pacman -S grub os-prober
$ grub-install -target=i386-pc -recheck /dev/sdx1
