The Raspberry Pi is a versatile credit card sized computer that can be used for a variety of electronic projects. The advantage of the Raspberry Pi is that you have the flexibility to install different operating systems and you are not limited to the Raspberry Pi operating system. This includes Arch Linux, which is revered for its simplicity. Fortunately, there is a version of Arch Linux designed to work with ARM processors. Let’s see how to install Arch Linux on Raspberry Pi.
Requirements
Before you begin, you will need the following:
- Raspberry pie
- Micro SD 8 GB (or more)
- Arch Linux ARM (Scroll down to find the Raspberry Pi image link.)
- Stable internet connection
- Computer system capable of reading SD card. (We’ll be using Linux for this tutorial.)
Prepare the SD card
First, you will need to make a list of the storage devices connected to your machine in order to identify which one is your SD card. Do this with the following command:
The SD card I am using is “/ dev / sdc”.
We need to format the SD card. To do this, run the following command, keeping in mind that you will need to replace “/ dev / sdc” with the name of your SD card:

You will need to erase all partitions that exist on the drive. To do this, type o
and hit enter in your terminal.

Enter p
in your terminal to check if there are any partitions left.

If there are no partitions left, go ahead and create the boot partition by typing n
, then p
, followed by 1
in your terminal. p
means primary, and 1
represents the first partition of the drive. You will need to press the Enter button after this sequence to continue.


When prompted for the last sector, type +100M
and press Enter.
Enter t
in the command prompt followed by c
to define the first partition as type “W95 FAT32 (LBA)”.

Type n
, followed by p
(for primary), then 2
in order to create the root partition.

Press Enter twice to accept the default settings for the first and last sectors.

Write the partition table and exit fdisk by entering w
.
We need to mount the FAT and ext4 file systems. To list the partitions, enter the following:
Your SD card will appear and you will be able to see the partitions. In my case, the partitions are “/ dev / sdb1” and “/ dev / sdb2”.

Copy Arch Linux files to SD card
The boot and root partitions must be mounted next. Do this with the following series of commands. Remember to replace the partition names in these commands with your partition names.
sudo mkfs.vfat /dev/sdb1 sudo mkdir boot sudo mount /dev/sdb1 boot sudo mkfs.ext4 /dev/sdb2 sudo mkdir root sudo mount /dev/sdb2 root

Now place the Arch Linux file you downloaded in your home folder and extract it to the root folder of your SD card with the following command:
sudo bsdtar -xpf ArchLinuxARM-rpi-2-latest.tar.gz -C root sync
The boot files will need to be moved to the boot partition of your SD card with:
You can unmount the two partitions with:
Insert the SD card into your Raspberry Pi.
Initial setup on Raspberry Pi
After inserting the SD card into your Raspberry Pi, launch it. You will either need to connect to the Internet via an Ethernet cable or a Wi-Fi network. To connect via Wi-Fi, first log in with the default root account. The username for this account is “root” and the password is “root”. Now run the following command:
A menu will load and you can select your Wi-Fi network and connect. Now, finalize the installation process by initializing the pacman keyring and filling the Arch Linux ARM package signing keys with:
pacman-key --populate archlinuxarm
You can go ahead and update the system packages with:
You need to change the default username. Do this with the following command:
usermod -l newusername oldusername
Also change the password with:
You will be prompted to enter a new password and then confirm it. To change the name of the home folder to reflect the new user name, run the following command:
usermod -d /home/newusername -m newusername
You must also change the password for the root account. Do this with:
In order to give sudo privileges to your user account, you will need to perform the following to install the sudo package:
You will need to edit the configuration file for sudo. Do this with:
Add newusername ALL=(ALL) ALL
under the line that reads root ALL=(ALL) ALL
Close and save the file, and you’re good to go.
Now that you have Arch Linux installed on the Raspberry Pi, there are a lot of things you can do, including installing and playing Minecraft and turning it into a NAS or Plex server. The limit is your imagination.
