}}
Then make sure the {{ic|sshd}} service is enabled and running:
{{bc|sudo systemctl enable --now sshd}}
= MariaDB =
== Data Directory ==
If you want to put your databases somewhere other than the default {{ic|/var/lib/mysql}}:
{{bc|
sudo mkdir <dir>
sudo chown -R mysql:mysql <dir>
}}
== tmpfs for tmpdir ==
The directory used by MariaDB for storing temporary files is named tmpdir. For example, it is used to perform disk based large sorts, as well as for internal and explicit temporary tables.
Create the directory with appropriate permissions:
{{bc|
sudo mkdir -pv <dir>
sudo chown mysql:mysql <dir>
}}
Find the id and gid of the mysql user and group:
{{hc|$ id mysql|2=
uid=27(mysql) gid=27(mysql) groups=27(mysql)}}
Add to your /etc/fstab file.
{{hc|/etc/fstab|2=
# Static information about the filesystems.
# See fstab(5) for details.
# <file system> <dir>          <type>  <options>                                      <dump> <pass>
...
tmpfs          /srv/sqltmp    tmpfs  rw,noatime,gid=933,uid=993,size=100M,mode=0750  0 0
...
}}
== Configuration File ==
{{hc|/etc/my.cnf.d/server.cnf|2=
...
[mysqld]
...
datadir=<dir>
skip-networking
tmpdir=<dir>
...
}}
== Initial Setup ==
{{bc|<nowiki>sudo mariadb-install-db --user=mysql --basedir=/usr --datadir=<dir></nowiki>}}
== Start the Server ==
{{bc|sudo systemctl enable --now mariadb}}
== Security Settings ==
{{bc|sudo mysql_secure_installation}}
Create a user:
{{hc|$ mysql -u root -p|2=
MariaDB> CREATE USER '<user>'@'localhost' IDENTIFIED BY '<password>';
MariaDB> GRANT ALL PRIVILEGES ON <database>.* TO '<USER>'@'localhost';
MariaDB> FLUSH PRIVILEGES;
MariaDB> quit
}}
= Redis =
Redis is used by several programs, including rspamd (e-mail), NextCloud, OnlyOffice, and Wordpress (optional).
By default, {{ic|redis}} is already configured to bind to 127.0.0.1:6379, but the Unix socket is not enabled.
{{hc|/etc/redis.conf|2=
...
# 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 {{ic|redis}} group so processes can access {{ic|redis}}

}}
== Basic Authorization ==
Some proxied sites have inadequate or no authentication method of their own.  Sometimes you may wish to provide an additional "bump in the road" for site access.  Nginx can use an {{ic|htpasswd}} file to control access.
{{bc|sudo htpasswd -c /etc/nginx/sites-enabled/htpasswd <user>}}
You will then be prompted for a password, and to confirm the password.  When finished, {{ic|htpasswd}} will create the file.
{{hc|/etc/nginx/sites-enabled/htpasswd|2=
<username>:<password-hash>
}}
{{tip|To update the file with more users or new passwords, omit the {{ic|-c}} parameter.}}
To use Basic Authentication with nginx, put these lines in the appropriate {{ic|server}} or {{ic|location}} stanzas:
{{bc|
auth_basic "Restricted By Username and Password";
auth_basic_user_file /etc/nginx/sites-enabled/htpasswd;
}}
== SSL Certificate Authorization ==
=== Server Configuration ===
{{hc|/etc/ssl/openssl.cnf|2=
[ CA_default ]
dir = /srv/ssl # Where everything is kept
certificate = $dir/ca.cert # The CA certificate
private_key = $dir/private/ca.key # The private key
RNDFILE = $dir/private/.rand # The private random number file
default_md = sha1 # use public key default MD
}}
{{bc|1=<nowiki>
sudo mkdir -p /etc/ssl/ca/{certs,crl,private}
sudo mkdir /etc/ssl/ca/ca/certs/users
sudo touch /etc/ssl/ca/index.txt
echo ’01’ | sudo tee /etc/ssl/ca/crlnumber
</nowiki>}}
=== Creating the Server Certificate ===
{{bc|1=
sudo openssl genrsa -des3 -out /srv/ssl/ca/private/ca.key 4096
sudo openssl req -new -x509 -days 1095 -key /srv/ssl/ca/private/ca.key -out /etc/ssl/ca/certs/ca.crt
sudo openssl ca -name CA_default -gencrl -keyfile /srv/ssl/ca/private/ca.key -cert /srv/ssl/ca/certs/ca.crt -out /srv/ssl/ca/private/ca.crl -crldays 1095
}}
=== Creating User Certificates ===
{{tip|The first two password prompts will be for the signing request.  The final one will be for the password for the certificate the user will import into their browser.}}
{{bc|1=
sudo export USRCRTDR="/srv/ssl/ca/certs/users"
sudo openssl genrsa -des3 -out ${USRCRTDR}/USERNAME.key 1024
sudo openssl req -new -key ${USRCRTDR}/USERNAME.key -out ${USRCRTDR}/USERNAME.csr
sudo openssl x509 -req -days 1095 -in ${USRCRTDR}/USERNAME.csr -CA /etc/ssl/ca/certs/ca.crt -CAkey /etc/ssl/ca/private/ca.key -CAserial /etc/ssl/ca/serial -CAcreateserial -out ${USRCRTDR}/USERNAME.crt
sudo openssl pkcs12 -export -clcerts -in ${USRCRTDR}/USERNAME.crt -inkey ${USRCRTDR}/USERNAME.key -out ${USRCRTDR}/USERNAME.p12
}}
{{tip|You can put this into a script to make it easier to issue new certificates.}}
=== Revoking User Certificates ===
{{bc|1=
sudo openssl ca -name CA_Default -revoke /etc/ssl/ca/certs/users/USERNAME.crt -keyfile /etc/ssl/ca/private/ca.key -cert /etc/ssl/ca/certs/ca.crt 
sudo openssl ca -name CA_Default -gencrl -keyfile /etc/ssl/ca/private/ca.key -cert /etc/ssl/ca/certs/ca.crt -out /etc/ssl/ca/private/ca.crl -crldays 1095
}}
=== Nginx Configuration ===
If you want to use certificate authorization in nginx, add these lines to the appropriate {{ic|server}} stanzas:
{{bc|
ssl_client_certificate /srv/ssl/certs/ca.crt;
ssl_crl /srv/ssl/private/ca.crl;
ssl_verify_client on;
}}
== Finalization ==
Enable your sites by using symlinks in {{ic|sites-enabled}} that point to the conf files in {{ic|sites-available}}
{{bc|sudo ln -s ../sites-available/<domain>.conf /etc/nginx/sites-enabled/<domain>.conf}}
Then make sure the {{ic|nginx}} service is enabled and running:
{{bc|sudo systemctl enable --now nginx}}
= Let's Encrypt =
{{bc|sudo certbot certonly --nginx --agree-tos}}
The {{ic|nginx}} plugin will guide you and help automate the process.
Take note that the {{ic|nginx}} configuration in this guide takes into account the settings suggested by {{ic|certbot}}.
== Automatic Renewal ==
These will automatically renew your certificates every 2 months on the first Sunday of the month at 4am.
=== Systemd ===

After [[Arch_Post-Installation_Checklist#Finalization|finalization]] you should now be able to log in and set up your virtual mailboxes.
= Rainloop =
Start with the [[Arch_Post-Installation_Checklist#Non-Proxied_Web_Site|Non-Proxied Web Site template]].
Change the following sections of the nginx conf file:
{{hc|/etc/nginx/sites-available/<domain>.conf|2=
...
location ~ /data {
deny all;
}
...
location ~ \.php$ {
fastcgi_pass unix:/run/php-fpm/php-fpm.sock;
fastcgi_index index.php;
include fastcgi.conf;
fastcgi_split_path_info ^(.+\.php)(.*)$;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}
...
}}
Download Rainloop
{{bc|
sudo cd /srv/http/<domain>
sudo wget https://www.rainloop.net/repository/webmail/rainloop-community-latest.zip
}}
Extract the zip file
{{bc|sudo unzip rainloop-community-latest.zip}}
Set the correct permissions on the files
{{bc|
sudo find . -type d -exec chmod 755 {} \;
sudo find . -type f -exec chmod 644 {} \;
}}
Set the correct owner on the whole web root
{{bc|sudo chown -R http:http /srv/http/<dir>}}
After you [[Arch_Post-Installation_Checklist#Finalize|finalize the setup]], you should now be able to access the Admini Panel at {{ic|<nowiki>http://<domain>/?admin</nowiki>}}.  The default login is admin:12345
From the Admin Panel, add your domain under Domains.  Use the public-facing domain for the Name, and {{ic|localhost}} for the IMAP and SMTP servers.
Under Login, set the Default Domain to {{ic|localhost}}.
Optionally, you can enable contacts.  You will need to manually set up a database and user, but that is the only configuration needed to do on your part.
For Security, you should enable all of the Security options.  You should also change the Admin Panel Access Credentials.
Click on the power-off icon in the upper-right corner to finish with the Admin Panel.
Navigate to {{ic|<nowiki>http://<domain></nowiki>}} to log in and access your mail.
= OnlyOffice Document Server =
On Arch, OnlyOffice can be installed via an [https://aur.archlinux.org/packages/onlyoffice-documentserver AUR package], with [https://helpcenter.onlyoffice.com/server/docker/document/docker-installation.aspx Docker], or with [https://snapcraft.io/onlyoffice-ds Snap].
== AUR Package ==
The [https://aur.archlinux.org/packages/onlyoffice-documentserver/ 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.
{{bc|
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.
{{bc|sudo mkdir /var/{lib,log}/onlyoffice}}
Issue one command to download and start the Docker instance.
{{bc|<nowiki>
sudo docker run -i -t -d -p [port]:80 --restart=always \
  -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice  \

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
{
	"aururl": "https://aur.archlinux.org",
	"buildDir": "/var/lib/pacman/aur/$USER",
	"editor": "nano",

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.
