Arch Linux Installation

Arch gang rise up

As you can notice, there are various tutorials in the net for the keyword “Arch installation”. As an Arch user, I will recommmend you to take a look at the Arch wiki for such an installation progess instead. So what is the purpose of this post? You may ask.

First of all, this post serves as a snippset for my arch installation. I don’t want to forget anything esstensial for my daily workflow incase I have to make a complete reinstall. Secondly, as personalized as this installation guide may seems, it may help new users in some ways.

Important
This installation guide is very outdated. Always follow the official guide from the ArchWiki for porper up-to-date instructions.

Now let’s get started:

Caution
/dev/nvme0n1 should be replaced with /dev/sda depending on different hardware.

That’s pretty much the whole installation of your Arch Linux system. You can customize your OS more later such as things like ricing,… The fun has just begun. Here are some screenshots of my machine over time.

  1. Hosts

    Check the configuration of your /etc/hosts file, a valid configuration looks like this:

    1
    
    #<ip-address> <hostname.domain.org> <hostname> 127.0.0.1 localhost.localdomain yourHostname ::1 localhost.localdomain yourHostname 
    
  2. Devices

  • You can identify your networking devices like this:

    1
    
    lspci | grep -i net
    
  • If your device is not listed, it is maybe an usb-device, so try this command:

    1
    
    lsusb
    
  • With the following command you can check the current state of all your network-devices:

    1
    
    ip link
    
  1. Install the wpa_supplicant tools

    1
    
    sudo pacman -S wpa_supplicant
    
  2. the wireless tools

    1
    
    sudo pacman -S wireless_tools
    
  3. Install the networkmanager

    1
    
    sudo pacman -S networkmanager
    
  4. Install the network-manager-applet aka nm-applet

    1
    
    sudo pacman -S network-manager-applet
    
  5. Install gnome-keyring

    1
    
    sudo pacman -S gnome-keyring
    
  6. Configuration

  • Make the networkmanager start on boot:

    1
    
    sudo systemctl enable NetworkManager.service
    
  1. Disable dhcpcd
  • Since networkmanager wants to be the one who handles the dhcpcd related stuff, you have to disable and stop dhcpcd:

    1
    2
    3
    4
    
    $ sudo systemctl disable dhcpcd.service 
    $ sudo systemctl disable dhcpcd@.service 
    $ sudo systemctl stop dhcpcd.service 
    $ sudo systemctl stop dhcpcd@.service
    
  1. Enable wpa_supplicant, if you want to use your wireless connection:

    1
    
    sudo systemctl enable wpa_supplicant.service
    
  2. Add your user to the network group:

    1
    
    gpasswd -a <USERNAME> network
    
  3. Turn off your network interface controllers, in my case eth0 and wlan0:

    1
    2
    
    $ ip link set down eth0
    $ ip link set down wlan0
    
  • Now start wpa_supplicant:

    1
    2
    
    $ ip link set down eth0
    $ ip link set down wlan0
    
  • Now Start the networkmanager:

    1
    
    sudo systemctl start NetworkManager.service
    

Finally, you should see the tray-icon on the top bar.
