At the end of this guide a fully functional Arch Linux will be installed.
|

|
||||
## 1. Preparation
|
||||
|
||||
Ahead of the installation an Arch boot-stick has to be created. The iso-file can be found on the [official website](https://www.archlinux.org/download/).
|
||||
The iso can be written on an USB-stick using ```dd```.
|
||||
After that the USB can be plugged in the system on which Arch should be installed.

|
||||
This has to be followed by your country id (for example a german keyboard layout would be ```de```,```de-latin1``` or ```de-latin1-nodeadkeys```.
|
||||
|
||||
## 2. Formatting of the target drive
|
||||
|
||||
Using ```lsblk``` you can list all the drives and partitions.
|
||||
Select a drive to install Arch on.
|
||||
In this step you can see if old partitions need to be deleted.
|
||||
For reasons of simplicity the following guide will assume the selected drive to be ```/dev/sda```.
|
||||
|
||||
### Clear disk completely:
|
||||
|
||||
This step can take quite a while especially for large drives.
|
||||
|
||||
- `dd status=progress if=/dev/zero of=/dev/sda`
|
||||
|
||||
Now all partitions should be removed.
|
||||
|
||||
### Create new partitions:
|
||||
|
||||
If you missclick during the progress of the following commands you can press ```CTRL+C``` to close the program.
|
||||
No changes will be made until the confirmation at the end.

||||
The swap partition will be created later under lvm.

## 3. Encryption
|
||||
|
||||
We need to find out which partitions is the one we want to encrypt.
|
||||
Using ```blkid | grep /dev/sda``` all partitions we created get listed.
|
||||
The right partition has the label ```Linux filesystem```.

Recovering of this passphrase is **not** possible.

## 4. Setup LVM
|
||||
|
||||
- `cryptsetup luksOpen /dev/sda2 lvm` - Opening encrypted partition and mapping it to ```/dev/mapper/lvm```
|
||||
- `pvcreate /dev/mapper/lvm` - Create a LVM physical volume
|
||||
- `vgcreate main /dev/mapper/lvm` - Create LVM Volume Group

||||
## 5. Create filesystems and mounting them temporarily
|
||||
|
||||
We have to find out which partition is our boot-partition.
|
||||
Using ```blkid | grep /dev/sda``` once again, we can identify it by looking for the ```EFI system partition``` label.
|
||||
The guide assumes this partition to be at ```/dev/sda1```.

@ -81,93 +91,131 @@ Now the created filesystems will be mounted for the installation.

- `swapon /dev/mapper/main-swap` - Mounting swap partition
|
||||

## 6. Prepare base installation (optional)
|
||||
|
||||
In this step the country specific mirrorserver for the installation will be configured.
|
||||
This will improve the download speed.
|
||||
|
||||
- `cp /etc/pacman.d/mirrorlist /etc/pacman.d/mirrorlist.bak` - Create a backup of mirrorlist
|
||||
- `grep -E -A 1 ".*Germany.*$" /etc/pacman.d/mirrorlist.bak | sed '/--/d' > /etc/pacman.d/mirrorlist` - Example command to only use *German* mirrors
|
||||
- `cat /etc/pacman.d/mirrorlist` - Check if the file is to your liking. If it is not, you can just recover by using ```mirrorlist.bak```
|
||||
|
||||
## 7. Starting base installation
|
||||
- `pacstrap /mnt base base-devel dosfstools gptfdisk lvm2 linux linux-firmware wpa_supplicant wireless_tools networkmanager vim` - Installation of main system with needed tools
|
||||
|
||||
- `pacstrap /mnt base base-devel dosfstools gptfdisk lvm2 linux linux-firmware networkmanager vim` - Installation of main system with needed tools
|
||||
- `pacstrap /mnt wpa_supplicant wireless_tools` - (optional) installation of wireless tools
|
||||
- `genfstab -Up /mnt > /mnt/etc/fstab` - creation of fstab
|
||||
- `arch-chroot /mnt` - Switch into the newly installed system
|
||||
- `echo ArchLinux > /etc/hostname` - Assign hostname. ```ArchLinux``` can be changed for any name of your preference.
|
||||
- `echo LANG=de_DE.UTF-8 > /etc/locale.conf` - Systemsprache festlegen
|
||||
|
||||
## 8. Set Region and Language
|
||||
|
||||
- `echo LANG=en_US.UTF-8 > /etc/locale.conf` - Assign system Language to be english (you can use other languages, look into the ```/etc/locale.conf``` for a list of all available languages)
|
||||
- `vim /etc/locale.gen` - Assigning system language
|
||||
- uncomment the lines depending on your needs.
|
||||
- `vim /etc/locale.gen` - Assigning system language by uncomment the lines depending on your needs.
|
||||
In this example:
|
||||
```
|
||||
en_US.UTF-8 UTF-8
|
||||
```
|
||||
- `locale-gen` - Generate languages
|
||||
- if you need any other keymap than english you can change it now for example to German by `echo KEYMAP=de-latin1 > /etc/vconsole.conf`.
|
||||
- `sed -i 's/MODULES=()/MODULES=(ext4)/g' /etc/mkinitcpio.conf` - Allow modules needed at boot
|
||||
- `sed -i 's/HOOKS=()/HOOKS=(base udev autodetect modconf block keyboard keymap encrypt lvm2 filesystems fsck shutdown)/g' /etc/mkinitcpio.conf` - Allow hooks needed at boot
|
||||
- if you need any other keymap than english you can change it now for example to German by `localectl --no-convert set-keymap de-latin1-nodeadkeys`.
|
||||
- `localectl status` - Check if the layout is right
|
||||
- `tzselect` - Set region
|
||||
|
||||
# 9. Configure and create kernel-image
|
||||
|
||||
- `vim /etc/mkinitcpio.conf`
|
||||
- Search the line `MODULES=()` and change it to:
|
||||
`MODULES=(ext4)`
|
||||
- Search the line `HOOKS=([...])` and change it to:
|
||||
`HOOKS=(base udev autodetect modconf block keyboard keymap encrypt lvm2 filesystems fsck shutdown)`
|
||||
- `mkinitcpio -p linux` - generate Kernel-Image
|
||||
|
||||
## 8. Install and configure UEFI bootloader
|
||||
- `bootctl install` - Prepare bootloader
|
||||
- `vim /boot/loader/entries/arch.conf` - Create configuration
|
||||
It is recommended to use UUIDs where possible.
|
||||
Please find out what the UUID of your drive is, use ```ls -l /dev/disk/by-uuid``` to do this.
