Use Cases

Arch Linux’s flexibility makes it suitable for a variety of homelab scenarios. Here are some key use cases and practical applications:

Personal Cloud Storage

By setting up Arch Linux with Nextcloud, you can create a personal cloud storage system, allowing you to access and share files securely from anywhere. This setup is not only cost-effective but also gives you full control over your data.

Media Server

Using Arch Linux in conjunction with software like Plex or Jellyfin, you can create a media server to stream movies, music, and TV shows to all your devices. This setup is ideal for those who want to centralize their media library and access it from multiple locations.

Development Environment

Arch Linux can be configured to serve as a development environment for programming, web development, or testing. Tools like Docker, VirtualBox, and various programming languages can be easily installed, providing a versatile setup for developers.

Installation/Setup

Step-by-Step Installation Guide

1. Download the Arch Linux ISO:

   Visit the official Arch Linux download page and download the latest ISO image.

2. Create a Bootable USB:

   Use a tool like Rufus (Windows) or dd (Linux) to create a bootable USB drive.

   sudo dd bs=4M if=/path/to/archlinux.iso of=/dev/sdX status=progress && sync

3. Boot from USB:

   Insert the USB drive into your machine and boot from it. You may need to change the boot order in your BIOS/UEFI settings.

4. Partition the Disk:

   Use fdisk or cfdisk to partition your disk. For example:

   cfdisk /dev/sdX

5. Format the Partitions:

   Format the partitions with the desired file systems. For example:

   mkfs.ext4 /dev/sdX1
   mkswap /dev/sdX2
   swapon /dev/sdX2

6. Mount the Partitions:

   Mount the root partition and create necessary directories:

   mount /dev/sdX1 /mnt
   mkdir /mnt/boot
   mount /dev/sdX3 /mnt/boot

7. Install the Base System:

   Use the pacstrap script to install the base system:

   pacstrap /mnt base linux linux-firmware

8. Generate the Filesystem Table:

   Create an fstab file:

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

9. Chroot into the New System:

   Change root into the new system:

   arch-chroot /mnt

10. Set the Time Zone:

    Set your time zone:

    ln -sf /usr/share/zoneinfo/Region/City /etc/localtime
    hwclock --systohc

11. Localization:

    Edit the /etc/locale.gen file and uncomment your locale:

    nano /etc/locale.gen
    locale-gen

12. Create a Hostname:

    Set your hostname:

    echo myhostname > /etc/hostname

13. Set the Root Password:

    Set a password for the root user:

    passwd

14. Install Bootloader:

    Install GRUB as the bootloader:

    pacman -S grub
    grub-install /dev/sdX
    grub-mkconfig -o /boot/grub/grub.cfg

15. Reboot:

    Exit the chroot environment, unmount partitions, and reboot:

    exit
    umount -R /mnt
    reboot

Congratulations! You have successfully installed Arch Linux.

Configuration

Configuring the System

After installation, you may want to configure your system to suit your needs.

Network Configuration

Enable and start the NetworkManager service:

systemctl enable NetworkManager
systemctl start NetworkManager

Installing a Desktop Environment

Install a desktop environment, such as GNOME or KDE, and a display manager:

pacman -S gnome gdm
systemctl enable gdm
systemctl start gdm

User Management

Create a new user and add to necessary groups:

useradd -m -G wheel -s /bin/bash username
passwd username

Edit the sudoers file to grant sudo privileges:

visudo

Uncomment the line:

%wheel ALL=(ALL) ALL

Security Considerations

Enable the firewall:

pacman -S ufw
systemctl enable ufw
systemctl start ufw
ufw enable
