Installed Arch Linux 64bit onto Raspberry Pi 4

Container
Reading Time: 5 minutes



I have 2 Raspberry Pi 4 in my home as below.

1. Nextcloud server
2. WordPress server, samba server, virus scan server



This time I decided to install Arch Linux onto them.
– I like Arch Linux OS.
– My laptop is installed Endeavour OS which is one of Arch Linux flavor.

In previous article I couldn’t install but solved.
This is note how to successfully install.

Installing Arch Linux 64bit

First please install Arch Linux 64bit onto Raspberry Pi 4 by following this page.



You can do by seeing this section.



In my case some lines on /etc/fstab is needed.
Unless doing this microSD is mounted Read-Only.

$ sudo vi /etc/fstab 
# Static information about the filesystems.
# See fstab(5) for details.

# <file system> <dir> <type> <options> <dump> <pass>
/dev/mmcblk0p1  /boot   vfat    defaults        0       0
/dev/mmcblk0p2  /   ext4    defaults        0       0 # <- 追記

Updating firmware by rpi-update

Next is to update firmware by rpi-update as mentioned on this video.



This is what I did.
Please note you need to run rpi-update on Raspberry Pi.

$ git clone https://github.com/Hexxeh/rpi-update
$ cd rpi-update
$ sudo BOOT_PATH=$HOME/boot ROOT_PATH=$HOME/root ./rpi-update

Boot

Connect microSD to Raspberry Pi and turn on.

You can log in by either of them.

#AB
User namealarmroot
Passwordalarmroot



First of all pacman to be up to date.

$ sudo pacman-key --init
$ sudo pacman-key --populate archlinuxarm
$ sudo pacman -Suy

Now you got vanilla Arch Linux!

Installed vim because vi is too simplified…

$ sudo pacman -S vim



I installed yay too.

$ sudo pacman -S base-devel git go
$ git clone https://aur.archlinux.org/yay.git
$ cd yay
$ makepkg -si

# Clean up
$ cd ..
$ rm -rf yay

Timezone configuration

I live in Yokohama so I configured timezone as Asia/Tokyo.

$ sudo timedatectl set-timezone Asia/Tokyo

IP address configuration

We can find ethernet device name is end0.

$ ip a show
(omit)
2: end0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 12:34:56:78:90:ab brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.94/24 brd 192.168.1.255 scope global end0
       valid_lft forever preferred_lft forever
(omit)



Then I created configuration file for end0.

$ sudo vim /etc/systemd/network/end0.network 
[Match]
Name=end0

[Network]
Address=192.168.1.23/24
Gateway=192.168.1.1
DNS=192.168.1.1

# Deleting existing file which affects end0
$ sudo rm /etc/systemd/network/en*.network

# Reboot to reflect change.
$ sudo reboot

Host name configuration

I configured host name because default host name is alarm.

$ sudo vim /etc/hostname
nextcloud-server

# Reboot to reflect change.
$ sudo reboot

Changing root user password

I changed root user password because default password is root which is easily predictable!

$ sudo -s 
passwd
New password: (Input password)
Retype new password: (Input password)
passwd: password updated successfully

Creating new user for daily operation

I created new user yasu for daily operation and added to /etc/sudoers.

$ sudo useradd yasu

$ sudo passwd yasu
New password: (Input password)
Retype new password: (Input password)
passwd: password updated successfully

$ id
uid=1000(alarm) gid=1000(alarm) groups=1000(alarm),998(wheel)
$ id yasu
uid=1001(yasu) gid=1001(yasu) groups=1001(yasu)

$ visudo
(omit)
yasu ALL=(ALL:ALL) ALL # Add to tail



I deleted user alarm because I don’t use.

$ sudo userdel -r alarm
$ ls /home/
yasu
$ id alarm
id: 'alarm': no such user



If you face error during userdel then this article may have solution.

Configuring SSH to use public key based authentication

I configured to use public/private key for SSH authentication by referring this article.

Cofiguring locale

If you want to add your locale please update /etc/locale.gen.

$ sudo /etc/locale.gen
(omit)
# en_JS.UTF-8 # <- Remove # to activate
(omit)

# Generating locale
$ sudo locale-gen

# Configuration of start up
$ sudo vim /etc/locale.conf
LANG=en_US.UTF-8

Installing argononed

I use this chassis so I need to install argononed to be able to control cooling fan.
You need to manually install onto Arch Linux.
Link to repository

$ sudo pacman -S i2c-tools lm_sensors python
$ mkdir argonone
$ cd argonone
$ curl -o PKGBUILD https://raw.githubusercontent.com/Elrondo46/argonone/master/PKGBUILD
$ curl -o argonone.install https://raw.githubusercontent.com/Elrondo46/argonone/master/argonone.install
$ makepkg --install

$ sudo systemctl daemon-reload
$ sudo systemctl enable argononed



At this time I need to modify small thing to properly run.
– bus.write_byte() after try

$ sudo vim /opt/argonone/bin/argononed.py
(omit)
def temp_check():
    fanconfig = ["65=100", "60=55", "55=10"]
    tmpconfig = load_config("/etc/argononed.conf")
    if len(tmpconfig) > 0:
        fanconfig = tmpconfig
    address = 0x1a
    prevblock = 0
    while True:
        temp = os.popen("cat /sys/class/thermal/thermal_zone0/temp").readline()
        val = float(temp) / 1000
        block = get_fanspeed(val, fanconfig)
        if block < prevblock:
            time.sleep(30)
        prevblock = block
        try:
            bus.write_byte(address,block) # From bus.write_byte_data(address,0,block)
        except IOError:
            temp = ""
        time.sleep(30)
(omit)



I configured and observed if it runs as expected or not.

$ sudo argonone-config 
--------------------------------------
Argon One Fan Speed Configuration Tool
--------------------------------------
WARNING: This will remove existing configuration.
Press Y to continue:Y
Thank you.

Select fan mode:
  1. Always on
  2. Adjust to temperatures (55C, 60C, and 65C)
  3. Customize behavior
  4. Cancel
NOTE: You can also edit /etc/argononed.conf directly
Enter Number (1-4):2

Please provide fan speeds for the following temperatures:
55C (0-100 only):10
60C (0-100 only):50
65C (0-100 only):100
Configuration updated.

# Clean up
$ cd ..
$ rm -rf argonone

Installing docker/docker-compose

I use docker/docker-compose for Nextcloud server so installed them.

$ sudo pacman -S docker docker-compose



If you are interested in running Nextcloud on docker, this article is helpful.

Installing vpnclient

I use SoftEther for VPN between LightSail on AWS and my home so installed vpnclient referring this article.



After installing I changed from password based authentication to public/private key based authentication.



I configured to automatically run vpnclient when it turns on.



That’s about it for initial setup.
After that you can configure as you like.

This is screenshot of htop of mine.
It shows memory consumption is 265MB which is very lightweight!

Conclusion

How was it?

If you are already Arch Linux then you will easily setup!
