Arch Linux for Developers: A Step-by-Step Guide to Building Your Ultimate Dev Environment

Why Arch Linux? Let’s Jump In!

Hey there, fellow developer community! If you’ve been browsing Linux distributions, you know there are tons of options out there. I’ve tested a few, gone on some Linux adventures, and finally landed on Arch Linux. And, wow, it’s been my go-to for over 11 years now. If you want a powerful development setup and want to learn Linux hands-on, Arch could be your golden ticket. Let’s explore why!

Starting Out with Linux

Before you dive into Arch Linux, get your feet wet with a few beginner-friendly options! Test out Linux Mint, Ubuntu, or Fedora on a virtual machine (like QEMU, VirtualBox, or VMware Player). These will help you get a feel for Linux without jumping straight into the deep end. Here’s what you’ll need to be comfortable with before going full Arch:

• Terminal Confidence: Yep, you’ll be typing commands often, so get cozy with the command line.
• OS Basics: Understand simple things like what a kernel is or why drivers matter.
• Hardware Awareness: Know a bit about your processor, GPU, network card, and RAM.
• Experimenting Spirit: Don’t worry—trying things out is part of the fun, and mistakes won’t blow up your machine!

Key Things for Choosing Your Linux Distro

When you’re picking a Linux distro, think about a few important things. The image below breaks down what makes up a Linux operating system.

1. Hardware Compatibility

Your hardware and the Linux kernel need to play nice together:

• New Hardware? Go for the latest LTS (Long-Term Support) or mainline kernel to avoid compatibility headaches.
• Buying Gear? Avoid hardware with tricky proprietary drivers. Look up compatibility (especially wireless cards by Broadcom, Mediatek) before buying.
• Struggling with Hardware? If Wi-Fi’s not working, try connecting via Ethernet or using USB tethering, Wi-Fi dongles, or modems to stay online.

2. Types of Linux Releases

Distros handle updates in different ways, so here’s a quick rundown:

• Point Releases: Updates on a set schedule, like Fedora or Debian Stable.
• LTS: Long-term support versions (like Ubuntu LTS), with years of support.
• Rolling Releases: Continuous updates with no version numbers, like Arch and OpenSUSE Tumbleweed.
• Semi-Rolling: Updates in chunks, like Manjaro.
• Testing Releases: Think of these as beta versions, like Fedora Rawhide.
• Enterprise/Corporate: Rock-solid, long-term releases, like Red Hat.

3. Package Managers

Every distro has a package manager—tools like apt, yum, dnf, and pacman help install and update software. The beauty of Linux is, if the package you want isn’t available, you can usually find a binary or build it yourself!

4. Desktop Environments (DEs)

Linux has a ton of different desktop environments (DEs). Popular ones include KDE, GNOME, XFCE, and Cinnamon. Try out different DEs and find one that fits your style.

Why Arch Linux? Here’s Why I Love It

After all my trials, I stuck with Arch Linux. Here’s why it’s been amazing for me:

1. Fresh Software Always

Arch Linux has the latest software, always. That means you get all the new features, bug fixes, and patches as soon as they’re available. I always use decent gaming laptops for power and portability(compared to Apple logos their price to specs ratio is top notch), so having the latest kernel updates keeps everything going smoothly.

2. Community Power

Arch is powered by its community. The Arch forums are full of wisdom, and the Arch Wiki is a treasure of guides and troubleshooting tips. The Arch Wiki is so good that even users of other distros rely on it!

3. Rolling Release

Arch is a rolling release, so you’re always on the latest version. No re-installs—just constant updates that keep your system fresh.

4. Pacman Package Manager

Pacman is Arch’s package manager. It’s fast, simple, and handles dependencies smoothly. Just type a few commands, and Pacman does the rest.

5. AUR: Arch User Repository

The AUR (Arch User Repository) is a huge collection of community-maintained scripts for software. If you can’t find something in the official repos, it’s probably in the AUR. Tools like yay, pacaur, or octopi make it easy to install AUR packages.

6. Zero Bloat

Arch only has what you choose to install—no unnecessary pre-installed software, just the stuff you actually want and need.

7. Build-Your-Own OS Vibes

With Arch, you’re the creator. Setting it up lets you build a custom OS tailored to your needs. It’s challenging but super rewarding, and there’s nothing like the feeling of running an OS you crafted yourself!

Let’s Begin 🚀

Alright, you’ve got the scoop on why Arch Linux is worth it, so let’s start cooking our very own operating system!

Step 1: Boot Up the Arch Linux Installer 🖥️

1. Download the ISO: Head over to the official Arch Linux download page and grab the latest installation .iso file. This file will help us get started!
2. Create Bootable Media:
   • On Windows: Use tools like Rufus, YUMI, or Ventoy to make your USB drive bootable.
   • On Linux or WSL: You can use the dd command to write the ISO to a USB drive.
   • On a Virtual Machine: Just load the ISO directly into your virtual machine.

Note: If your hard drive is already full, you might need to shrink an existing partition to create some unallocated space for installing Arch. About 40GB should be more than enough.

1. Boot It Up: Insert your bootable media into your PC and restart it. You’ll see the installer menu—choose the first option to kick things off!

   

Now, you should see a root terminal waiting for you.

---

Step 2: Configure Network 🌐

We need an internet connection to download the packages that will build our system. Let’s find the network interface!

List Network Interfaces

ls /sys/class/net

This command lists all network interfaces. You might see something like:

enp12s0  lo  wlp0s20f3

• lo - Ignore this one; it’s just a virtual loopback device for local communication (like talking to yourself; localhost, 127.0.0.1 …).

If You’re Wired (Ethernet)

If you have a cable plugged in, you’re good to go! No extra steps needed!

If You’re on WiFi

The wlp* device is likely your WiFi. Let’s confirm it:

(dmesg can show logs for device initializations at the kernel level.)

dmesg | grep -i wlan

We’ll use iwd to set up WiFi. Run these commands in sequence:

1. Start the iwd Interactive Shell:

   iwctl
   

2. List Devices:

   device list
   

3. Power On WiFi (if it’s off):

   device wlan0 set-property Powered on # wlan0 is the name of the WiFi interface
   

   If there’s an error, check if it’s blocked by rfkill: (rfkill is a tool for managing radio devices like Bluetooth and WiFi; it helps with security and blocking issues.)

   rfkill
   

4. If it’s blocked, unblock it and try turning the device on again:

   rfkill unblock wlan && device wlan0 set-property Powered on
   

5. Scan for Networks:

   station wlan0 get-networks
   

6. Connect to Your Network (enter your WiFi password when prompted):

   station wlan0 connect "Network_SSID"
   

7. Check Connectivity: Let’s do a quick test to see if we’re connected:

   ping -c 3 google.com
   

   And that’s it! Your network is set up, and we’re ready to install Arch. 🎉

Step 3: Preparing Disk Partitions 🗂️

Alright, let’s get ready to create some disk partitions! This is super important because a tiny mistake can wipe out your data. We’ll use a tool called cfdisk that gives us a nice visual interface to manage our disks.

Understanding Linux File System

Before we dive in, let’s take a quick peek at what the Linux file system looks like. We’re going to create something similar on our hard drive!

/
├── bin         # Important command files (like ls, cp, mv)
├── boot        # Boot files for starting up your system
├── dev         # Device files (like hard drives and USBs)
├── etc         # Configuration files for your system
├── home        # User home directories (like /home/user)
├── lib         # Essential libraries for commands
├── media       # Mount points for USB drives and CDs
├── mnt         # Temporary mount points
├── opt         # Optional software and packages
├── proc        # System information
├── root        # Home directory for the root user
├── run         # Temporary files since the last boot
├── sbin        # System administration commands
├── srv         # Service-related data
├── sys         # Kernel and system information
├── tmp         # Temporary files cleared on reboot
├── usr         # User-installed programs and libraries
│   ├── bin     # User-installed command files
│   ├── lib     # Shared libraries for user commands
│   └── share   # Shared files and docs (like icons)
└── var         # Variable data (like logs and databases)
    ├── log     # Log files
    ├── cache   # Cached data
    ├── lib     # Variable library files
    └── tmp     # App-created temporary files

1. Identify Your Disk 🧐

First, we need to find out which disk we want to install Linux on. The command below will show you the disks and their sizes:

lsblk

You’ll see something like this:

NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
nvme1n1     259:0    0 953.9G  0 disk
nvme0n1     259:10   0 476.9G  0 disk

2. Open cfdisk for Partitioning 🔧

Now, let’s open cfdisk to create our partitions. If your hard drive is nvme1n1, use this command:

cfdisk /dev/nvme1n1

This will pop up a window where you can create partitions. Here’s what you need to make:

• Root Partition (/) for the main system
• Swap Partition for extra memory
• EFI Boot Partition if your computer uses UEFI (most modern PCs do)
• You can also create a separate partition for your home directory (/home) if you like.

For example, if you have about 163GB free, you could create:

• 60GB for root (/)
• 90GB for home (/home)
• 3GB for swap (helps when your RAM is full)
• 800MB for EFI (if using UEFI)

Once you’ve created the partitions, select the Write option in cfdisk to save your changes and exit.

3. Format Your Partitions 🎨

Now, it’s time to format those partitions! We’ll use EXT4 for the root and home partitions, and FAT32 for the EFI partition. Let’s format:

First, check your partitions again with lsblk:

lsblk

You’ll see your newly created partitions listed. Now, format them:

mkfs.ext4 /dev/nvme1n1p6 # Format root partition
mkfs.ext4 /dev/nvme1n1p7 # Format home directory
mkfs.vfat -F32 /dev/nvme1n1p8 # Format EFI partition
mkswap /dev/nvme1n1p9 # Set up Linux swap

4. Mount Your Partitions 🏔️

Time to mount those formatted disks! This will prepare them for the Arch Linux installation. Run these commands:

mount /dev/nvme1n1p6 /mnt # Mount root partition
mkdir -p /mnt/home && mount /dev/nvme1n1p7 /mnt/home # Mount home directory
mkdir -p /mnt/boot/efi && mount /dev/nvme1n1p8 /mnt/boot/efi # Mount EFI partition
swapon /dev/nvme1n1p9 # Enable swap

Check your mount points one more time to ensure everything is set up correctly:

lsblk

Your output should look something like this:

NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
nvme1n1     259:0    0 953.9G  0 disk
├─nvme1n1p6 259:6    0    90G  0 part /home
├─nvme1n1p7 259:7    0    60G  0 part /
├─nvme1n1p8 259:8    0   800M  0 part /boot/efi
└─nvme1n1p9 259:9    0     3G  0 part [SWAP]
nvme0n1     259:10   0 476.9G  0 disk

Congratulations! Your partitions are all set and ready for the Arch Linux installation. 🎊 Let’s move on to the next step!

---

Step 4: Installing Core Linux Packages and Configurations 🐧

Now, it’s time to bring your Arch Linux to life! We’ll install the essential core packages that make up the Linux system using the pacstrap command. This command will set up the Linux kernel and other important tools on your mounted partitions. Let’s get started!

Install the core packages:

pacstrap -K /mnt base linux linux-firmware \
linux-headers base-devel nano sudo \
intel-ucode \ # use only if you have an Intel CPU
amd-ucode \ # only for AMD CPU

(If you’re not sure about your CPU type, you can check it by running this command:)

lscpu | grep -i "Model name"

Generate fstab: This step creates a file called fstab that tells Linux how to mount disk partitions when it starts up. Let’s make it!

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

Check your fstab: To make sure everything is in order, let’s verify that all your partitions are listed in fstab. You can do this by running:

cat /mnt/etc/fstab

Change into the new system: Now we need to switch into the mounted file system so we can start making configurations. We do this with the arch-chroot command.

arch-chroot /mnt

Set up localization settings: Next, we’ll set the language and locale for your system. Open the file /etc/locale.gen and find the line LANG=en_US.UTF-8. Uncomment it (just remove the # at the start) and feel free to uncomment any other localizations you want.

nano /etc/locale.gen

After editing, run this command to generate the locales:

locale-gen

Set the computer name: Let’s give your system a name! This name will identify your computer on the network. You can replace myhostname with whatever name you like.

echo myhostname >> /etc/hostname

Set a password for the root user: Now, let’s secure your system by setting a password for the root user.

passwd

Create a new user: It’s a good idea to create a normal user account for everyday tasks. This user will have some extra privileges. Just replace "your username" with your chosen name.

useradd -m -g users -G wheel,storage,power,audio -s /bin/bash "your username"

Set a password for your new user:

passwd "your username"

Give the new user sudo privileges: Now, we want this user to be able to run commands as a superuser (the admin). To do that, we’ll edit the sudo configuration:

EDITOR=nano visudo

In the file, find the line that says %wheel ALL=(ALL:ALL) ALL and uncomment it (again, just remove the #). Then, save the changes.

Install and enable Network Manager: Finally, let’s install the network manager tools. This will help your system discover and connect to networks when it starts up.

pacman -S networkmanager
systemctl enable NetworkManager

Now you’re all set! You’ve installed the core packages and configured your system. Your Arch Linux is well on its way to becoming fully functional! 🎉

---

Step 5: Install Bootloader 🚀

There are many bootloaders out there, but I chose GRUB. Why? Because it’s mature and has lots of features!

1. First, install the required packages.

   pacman -S grub \
   os-prober \
   efibootmgr # only if the system supports UEFI
   

2. Now, install GRUB. If you have a UEFI system, run:

   grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=GRUB
   

   If you have an older legacy system, use this command:

   grub-install --target=i386-pc /dev/xxx # xxx is the storage name.
   

3. Generate configurations. If you are dual-booting with Windows, find the line that says GRUB_DISABLE_OS_PROBER=false in the default GRUB configuration file and uncomment it.

   nano /etc/default/grub
   

   Next, generate the GRUB configuration.

   grub-mkconfig -o /boot/grub/grub.cfg
   

---

Step 6: Installing a Desktop Environment 🖼️

A desktop environment (DE) gives you a friendly user interface to interact with your Linux system. There are many DEs to choose from. KDE is a complete and feature-rich option. If you prefer something simpler, you might like GNOME, Cinnamon, or XFCE. This setup focuses on KDE.

To install KDE, run:

pacman -S plasma-meta kde-system kde-utilities \
kde-graphics # optional software

After that, enable the login manager that comes with the plasma-meta package group:

systemctl enable sddm

Now everything is ready! Exit the chroot session, unmount the disks, and restart your system:

exit
umount -R /mnt
swapoff /dev/"swap partition name"
reboot

When your system boots up, you will be greeted by your new desktop environment!

---

Step 7: Post Install Packages 🛠️

Alright, let’s pimp up your Arch Linux setup with some essential packages! Here’s how you can make your system more powerful with extra tools and dev environments.

1. Add AUR Support

The AUR (Arch User Repository) is a huge collection of community-maintained scripts for installing software that’s not available in the default pacman repositories. You can either download and run these scripts yourself or use a tool to make it super easy. My go-to choice is yay, because it works just like pacman—easy to remember! Other popular options are pacaur, aurman, aura, pacseek, etc.

# Install yay
sudo pacman -S --needed git base-devel && git clone https://aur.archlinux.org/yay.git && cd yay && makepkg -si

With yay, you can:

• Update the system: yay
• Search for a package: yay -Ss xyz
• Install a package: yay -S xyz
• Uninstall a package: yay -Rns xyz
• Force remove (use with caution): yay -Rdd xyz
• Clean unused dependencies: yay -Yc
• Show remote package info: yay -Si xyz
• Show local package info: yay -Qi xyz
• List all installed packages: yay -Qq
• List explicitly installed packages: yay -Qqe

2. Proprietary Drivers

If you have a laptop with hybrid graphics (like Intel + Nvidia or AMD + Nvidia), you’ll want to get the right drivers. To check what graphics cards you have, run:

lspci | grep -E 'VGA|3D'

Then, install the drivers you need:

sudo pacman -S mesa xf86-video-intel         # For Intel GPUs
sudo pacman -S nvidia nvidia-utils nvidia-settings  # For Nvidia GPUs
sudo pacman -S mesa xf86-video-amdgpu        # Open-source AMD driver

If you’ve got Nvidia hybrid graphics, you can install envycontrol to easily switch between GPUs.

yay -S envycontrol

To list or set the GPU mode:

envycontrol --query            # Show current GPU
envycontrol --switch nvidia     # Options: integrated, hybrid, nvidia

3. Install a Web Browser

Choose your favorite browser(s) and install them:

yay -S google-chrome           # Google Chrome
pacman -S chromium             # Open-source version of Chrome
pacman -S firefox              # Mozilla Firefox
yay -S opera                   # Opera browser

---

Step 8: Setting Up Development Environments 🧑‍💻

Let’s get your coding environment all set up! Arch Linux is great for developers, and here’s how you can get started with various programming tools.

1. Java Development Kit (JDK)

yay -Ss jdk                     # List available JDK versions
yay -S jdk-lts                  # Install long-term support (LTS) version, or specify another version if you need

To check or set up Java versions:

archlinux-java status           # Show installed JDKs and the current default
archlinux-java set <JAVA_ENV_NAME> # Set default Java version

2. Python Development

First, install pyenv to manage different Python versions.

sudo pacman -S pyenv
pyenv install 3.8               # Install Python 3.8.x
pyenv install 3.11              # Install Python 3.11.x
pyenv global 3.11               # Set Python 3.11 as the default

3. Node.js Environment

Install nvm (Node Version Manager) first:

yay -S nvm

Add nvm paths to ~/.bashrc:

echo 'export NVM_DIR="$HOME/.nvm"' >> ~/.bashrc
echo '[ -s "/usr/share/nvm/init-nvm.sh" ] && \. "/usr/share/nvm/init-nvm.sh"' >> ~/.bashrc
source ~/.bashrc

Now you can install any Node version:

nvm install x.y.z               # Install Node version x.y.z
nvm use x.y.z                   # Set current Node version
node --version                  # Check the current Node version

4. Ruby Development Environment

Install rbenv for Ruby version management:

yay -S rbenv
yay -S ruby-build               # Required for installing Ruby versions
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
source ~/.bashrc

To install and set up Ruby:

rbenv install 3.0.0
rbenv global 3.0.0              # Set Ruby 3.0.0 as default
gem -v                          # Check that Ruby is correctly set up

5. .NET Environment

yay -S dotnet-install
dotnet-install --channel 8.0    # Install the .NET version 8.0

6. Docker

Install and set up Docker:

sudo pacman -S docker
sudo usermod -aG docker $USER   # Add your user to the Docker group
sudo systemctl enable docker

After a system reboot, check that Docker is running:

sudo systemctl status docker

7. Database Tools

For database management, here are some good gui tools:

sudo pacman -S dbeaver          # DBeaver, supports multiple databases
yay -S pgadmin4-desktop         # Postgres admin tool
yay -S sql-workbench            # MySQL Workbench
yay -S mongodb-compass          # MongoDB management tool
