Installing Arch Linux on a ServerAstra cloud instance or dedicated server

This guide provides step-by-step instructions on how to install Arch Linux. This process is aimed at users with a basic understanding of Linux commands and network configurations.


  • Either a server or cloud instance with ServerAstra.
  • Arch Linux ISO access
  • Basic familiarity with Linux command line interface.

TIP: For BMC access please refer to Guide to Interpreting the YAML Configuration and Connecting to IPKVM and IPMI IPKVM guide

Step 1: Connecting the Arch Linux ISO

  • Select the ISO for Arch Linux version either:
    • from our repository and:
      • attach it in the VPS configuration CDROM section
      • attach it via provisioned BMC (IPMI, iDRAC, KVM over IP, etc)
    • download from official Arch Linux website and:
      • upload to our cloud panel (size must be less than 6GB) in the VPS configuration section with [+] button
      • connect to BMC (IPMI, iDRAC, KVM over IP, etc) in the IPKVM console (either JAVA or HTML5 depending on server brand)

Step 2: Boot the Server

  1. Restart your server.
  2. Access your server’s boot menu and select the option to boot from the virtual CDROM containing the Arch ISO.
  3. If you are unable to boot to ISO seek help from our Support team to assist.

Step 3: Set Up the Internet Connection

  • Ensure your server is connected to the internet. For Cloud Instance connections, Arch Linux should connect automatically via DHCP. If you need to configure it manually or set up a wireless connection, run the following commands in the root console of ISO booted Arch Linux:
    ip link

    Note the network interface name which is connected and up and running. Replace in the next command %NETIF% with that interface name and %IP% and %GW with designated IP address (including subnet) and gateway from YAML configuration sent to you by ServerAstra team upon deployment of dedicated server

    ip addr add %IP% dev %NETIF%
    ip route add default via %GW%

    For example if your IP is, gateway is and interface name is enp45s0 the resulting command will be:

    ip addr add dev enp45s0
    ip route add default via

Step 4: Partition the Disk

  1. Use the lsblk command to list all available disks and partitions.

  2. Partition the disk using fdisk (for MBR), cfdisk, sfdisk or parted. For a simple setup, assuming disk name /dev/sda:

    • A root partition (/dev/sda1)
    • Optionally, a swap partition (/dev/sda2)

    Example using fdisk:

    fdisk /dev/sda
    > n       # Create new partition
    > p       # Primary partition
    > 1       # Partition number
    >         # Default - start at beginning of disk
    > +20G    # Partition size
    > n       # Create another new partition
    > p       # Primary partition
    > 2       # Partition number
    >         # Default, starts immediately after preceding partition
    > +2G     # Swap partition size
    > t       # Change partition type
    > 2       # Select partition 2
    > 82      # Linux swap / Solaris
    > w       # Write changes and exit

Step 5: Format the Partitions

mkfs.ext4 /dev/sda1 # Format the root partition
mkswap /dev/sda2    # Set up the swap partition
swapon /dev/sda2    # Enable the swap partition

Step 6: Mount the File System

mount /dev/sda1 /mnt

Step 7: Install Arch Linux

  1. Install the base system and essential packages:
pacstrap /mnt base linux linux-firmware nano openssh grub
  1. Generate an fstab file:
genfstab -U /mnt >> /mnt/etc/fstab

Step 8: Chroot into Your Installation

arch-chroot /mnt

Step 9: Configure the System

  1. Set the time zone:
ln -sf /usr/share/zoneinfo/Region/City /etc/localtime
hwclock --systohc
  1. Generate locales by uncommenting en_US.UTF-8 UTF-8 and other needed locales in /etc/locale.gen, then run:
  1. Create the locale.conf file, and set the LANG variable:
echo "LANG=en_US.UTF-8" > /etc/locale.conf
  1. Set the hostname:
echo "serverastra-customer" > /etc/hostname
  1. Setup networking, replace %NETIF%, %IP% and %GW% like mentioned in Step 3, %DNS% is Nameserver from same YAML configuration:
systemctl enable systemd-networkd
cat << EOF > /etc/systemd/network/

Step 10: Install Bootloader

You can install a variety of bootloaders in Arch Linux. We will pick the most popular, GRUB. Installation:

pacman -S grub
grub-install --target=i386-pc /dev/sda
grub-mkconfig -o /boot/grub/grub.cfg
mkinitcpio -P

TIP: If you encounter pacman errors due to keys expiring - try repopulating keys and reinstalling keyring:

pacman-key --init
pacman-key --populate
pacman -Sy archlinux-keyring

Step 11: Set Root Password


Step 12: Reboot

  1. Exit from chroot:
  1. Unmount all partitions:
umount -R /mnt
  1. Reboot the server:

Now, your server should boot into Arch Linux. Customize your setup by installing additional packages and configuring services as needed.
