Passwords & User Creation

Make sure root has a password.

Make sure you have a primary user set up.

sudo useradd -m -u <id -ge 1000> -g users -G wheel,games,video,audio,optical,storage,scanner,power <user>
sudo passwd <user>

/etc/fstab

Time Zone

sudo ln -sf /usr/share/zoneinfo/<region>/<city> /etc/localtime
sudo hwclock --systohc

Localization

Un-comment your desired locales in /etc/locale.conf, then run

sudo locale-gen

If you don't have the default /etc/locale.gen file:

sudo rm /etc/locale.gen
sudo pacman -Syu glibc

Edit /etc/locale.conf as you see fit

/etc/locale.conf

LANG=en_US.UTF-8
LANGUAGE=en_US
LC_COLLATE=POSIX
LC_MESSAGES=C
LC_CTYPE=en_US.UTF-8
LC_NUMERIC=en_US.UTF-8
LC_TIME=en_US.UTF-8
LC_MONETARY=en_US.UTF-8
LC_PAPER=en_US.UTF-8
LC_NAME=en_US.UTF-8
LC_ADDRESS=en_US.UTF-8
LC_TELEPHONE=en_US.UTF-8
LC_MEASUREMENT=en_US.UTF-8
LC_IDENTIFICATION=en_US.UTF-8

Set up /etc/vconsole.conf with a keymap and (optionally) a font:

/etc/vconsole.conf

KEYMAP=us
FONT=Lat2-Terminus16

Initramfs

Look for and edit the following lines:

/etc/mkinitcpio.conf

MODULES=([amdgpu|bochs_drm|cirrus|i915|nouveau|(nvidia nvidia_modeset nvidia_uvm nvidia_drm)] [ehci_pci usb_storage]>)
HOOKS=(base udev autodetect modconf block [zfs] filesystems keyboard fsck [encrypt] keymap consolefont)
COMPRESSION=lz4

Networking

Host Name

Make sure a host name is set in /etc/hostname

Then edit /etc/hosts

/etc/hosts

127.0.0.1	localhost.localdomain	locahost
::1		localhost.localdomain	localhost
127.0.1.1	<hostname>.localdomain	<hostname>

Static Addressing

Use systemd-networkd when a machine will use a static address without consulting a DHCP server.

IPv4 Only

/etc/systemd/network/network.network

[Match]
MACAddress=<mac-address>
[Network]
Address=<ipv4-address>/<mask>
DNS=<ipv4-address>
Gateway=<ipv4-address>
LinkLocalAddressing=no
IPv6AcceptRA=no

IPv4 & IPv6

/etc/systemd/network/network.network

[Match]
MACAddress=<mac-address>
[Network]
Address=<ipv6-address>/<mask>
DNS=<ipv6-address>
Gateway=<ipv6-address>
Address=<ipv4-address>/<mask>
DNS=<ipv4-address>
Gateway=<ipv4-address>

Dynamic Addressing

It's preferable to use connman or Network Manager for dynamic addresses as systemd-networkd doesn't play well with interfaces coming and going.

If you'd rather use systemd-networkd for DHCP:

/etc/systemd/network/network.network

[Match]
MACAddress=<mac-address>
[Network]
DHCP=yes
[DHCP]
UseMTU=true

Packages

Mirror List

Install and use reflector to automate the use and selection of mirrors.

sudo pacman -Syu reflector
sudo reflector -c <country> -p https -l 5 --sort rate --save /etc/pacman.d/mirrorlist

Yay

Make sure you have the base-devel group installed.

sudo pacman -Syu --needed base-devel git

Create a directory where AUR build files will go

sudo mkdir /var/lib/pacman/aur
sudo chmod 1777 /var/lib/pacman/aur
$ mkdir /var/lib/pacman/aur/$(whoami)

Build yay.

$ cd /var/lib/pacman/aur/$(whoami)
$ git clone https://aur.archlinux.org/yay.git
$ cd yay
$ makepkg -Ccisr

The create the configuration file.

~/.config/yay/config.json

General Utilities

These packages supplement the base system.

yay -Syu --needed adduser archey3 arj bind-tools bzip2 dmidecode dnsutils fail2ban git haveged htop hwdetect inxi iotop lshw lzop nano ncdu openssh p7zip pacman-contrib perl-rename pkgfile polkit ranger rsync strace sudo tmux unrar unzip vim whois zip

If you are not running inside a VM, you may also wish to add these packages:

yay -Syu hddtemp lm_sensors memtest86+ smartmontools

The havaged service can be enabled and started right away as no configuration is needed.

sudo systemctl enable --now haveged

Your sensors need to be configured before starting the lm_sensors service.

Note: This package is useless inside a VM.

sudo sensors-detect
sudo systemctl enable --now lm_sensors

Don't start fail2ban or sshd quite yet as they have configuration that needs to be done.

Docker

This is only needed for OnlyOffice

yay -Syu docker
sudo systemctl enable --now docker

Redis

Redis is used by several programs, including rspamd (e-mail), NextCloud, OnlyOffice, and Wordpress (optional).

By default, redis is already configured to bind to 127.0.0.1:6379, but the Unix socket is not enabled.

/etc/redis.conf

...
# Unix socket.
#
# Specify the path for the Unix socket that will be used to listen for
# incoming connections. There is no default, so Redis will not listen
# on a unix socket when not specified.
#
unixsocket /run/redis/redis.sock
unixsocketperm 700
...

You will also need to add users to the redis group so processes can access redis

for username in http rspamd; do sudo usermod -G redis ${username}; done

Let's Encrypt

sudo certbot certonly --nginx --agree-tos

The nginx plugin will guide you and help automate the process.

Take note that the nginx configuration in this guide takes into account the settings suggested by certbot.

Automatic Renewal

These will automatically renew your certificates every 2 months on the first Sunday of the month at 4am.

Systemd

/etc/systemd/system/certbot.service

OnlyOffice Document Server

On Arch, OnlyOffice can be installed via an AUR package, with Docker, or with Snap.

AUR Package

The AUR package was broken at the time of this writing.

Snap

Snap did not work for me. However, this might have been due to the Snap's Redis service conflicting with that of the host's.

Docker

The Docker version requires PostreSQL, RabbitMQ, and Redis to be set up. Be sure to install and configure those first.

Once that is complete, set up the database and database user.

sudo -u postgres psql -c "CREATE DATABASE onlyoffice;"
sudo -u postgres psql -c "CREATE USER onlyoffice WITH password 'onlyoffice';"
sudo -u postgres psql -c "GRANT ALL privileges ON DATABASE onlyoffice TO onlyoffice;"

Create the following directories.

sudo mkdir /var/{lib,log}/onlyoffice

Issue one command to download and start the Docker instance.

sudo docker run -i -t -d -p [port]:80 --restart=always \
   -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice  \
   -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice \
   -v /app/onlyoffice/DocumentServer/db:/srv/psql  onlyoffice/documentserver

Configure nginx to act as a proxy

/etc/nginx/sites-available/<domain>

upstream docservice {
	server <docker-ip>:8888;
}

map $http_host $this_host {
	""	$host;
	default	$http_host;
}

map $http_x_forwarded_proto $the_scheme {
	default	$http_x_forwarded_proto;
	""	$scheme;

}

map $http_x_forwarded_host $the_host {
	default	$http_x_forwarded_host;
	""	$this_host;
}

map $http_upgrade $proxy_connection {
	default	upgrade;
	""	close;
}

proxy_set_header	Upgrade $http_upgrade;
proxy_set_header	Connection $proxy_connection;
proxy_set_header	X-Forwarded-Host $the_host;
proxy_set_header	X-Forwarded-Proto $the_scheme;
proxy_set_header	X-Forwarded-For $proxy_add_x_forwarded_for;

server {
	listen		80;
	listen		[::]:80;
	server_name	<domain>;
	server_tokens	off;
	rewrite		^ https://$host$request_uri? permanent;
}

server {

	listen				443 ssl http2;
	listen				[::]:443 ssl http2;
	server_name			ods.bwt.com.de;
	server_tokens off;

	ssl_certificate			/etc/letsencrypt/live/<domain>/fullchain.pem;
	ssl_certificate_key		/etc/letsencrypt/live/<domain>/privkey.pem;
	ssl_trusted_certificate		/etc/letsencrypt/live/<domain>/chain.pem;

	add_header			Strict-Transport-Security max-age=31536000;
#	add_header			X-Frame-Options SAMEORIGIN;
	add_header			X-Content-Type-Options nosniff;

	access_log			/var/log/nginx/access.log main buffer=32k;
	error_log			/var/log/nginx/error.log error;
	limit_req			zone=gulag burst=200 nodelay;


	# ACME challenge
	location ^~ /.well-known {
		allow			all;
		alias			/var/lib/letsencrypt/$host/.well-known;
		default_type		"text/plain";
		try_files		$uri =404;
	}

	location / {
		proxy_pass		http://docservice;
		proxy_http_version	1.1;
	}
}

After finalizing, you should now be able to navigate to https://<domain> and see the OnlyOffice Document Server welcome page with a green checkmark indicating everything is running properly.
