Packages provide the basic components of an operating system, along with shared libraries, applications, services, and documentation.
This document will guide new users through basic needs about:
- installing packages (software to install) and ..
- minimal started setups (configurations to the system).
If more in depth information is needed, see the Alpine package management behavior section in this document page.
New users: hostname and network wired connection
After installing Alpine Linux, you might need to configure your system to properly work for your use case, since Alpine's main utilities are busybox
-based:
Setting the hostname
A hostname is a unique name created to identify a machine on a network, configured in /etc/hostname.
To change the computer's hostname edit the /etc/hostname
file or execute the following command
(make sure to replace myhostname
with your desired hostname):
# echo "myhostname" > /etc/hostname
You should also add the hostname to your hosts file (/etc/hosts
):
127.0.0.1 localhost localhost.localdomain 127.0.1.1 myhostname myhostname.localdomain ::1 localhost localhost.localdomain
Network configuration
There are three types of internet connections: wired (Ethernet), wireless (WiFi) and PPTP (modems). This section will focus only on wired connections, for wireless configuration read the Connecting to a wireless access point article.
This section will help to update and configure your network interfaces, please plug your network cable in and then go to the console and run the DNS and interfaces configuration scripts.
cat > /etc/network/interfaces << EOF auto lo iface lo inet loopback EOF setup-interfaces -a echo -e "\n" | setup-dns 8.8.8.8 rc-service networking restart
Default root configurations
The root user are the god of the Linux Alpine system, run only the most deep in task, and must not be used as normal user neither for common task. For common users the last section of this page document will show you all the needs.
When Alpine Linux is first installed by default it comes with the user root with no password set so the first step after boot into alpine fresh install are set a password to the user root, if during install was run setup-alpine to change root password, that will be already set and can be changed with those setup steps described here. More info in the Setting users wiki page.
cat > /root/.cshrc << EOF unsetenv DISPLAY || true HISTCONTROL=ignoreboth EOF cp /root/.cshrc /root/.profile echo "secret_new_root_password" | chpasswd
Of course you must changed "secret_new_root_password" by a proper password provided by you.
New users: common needed package to install
Packages and programs on alpine are described on Alpine_newbie: Packages overall info.
enable repository packages
Repositories are need due are where will be retrieve those packages of programs as described on Alpine_newbie: Packages overall info, run:
cat > /etc/apk/repositories << EOF http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/main http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/community EOF apk update
install basic tools
As explain in Alpine Linux:Overview, the system always will be minimalist, so if you expected a behavior like others linux those will be provided a minimal similitude to, runs:
apk add attr dialog dialog-doc bash bash-doc bash-completion grep grep-doc apk add util-linux util-linux-doc pciutils usbutils binutils findutils readline apk add man man-pages lsof lsof-doc less less-doc nano nano-doc curl curl-doc export PAGER=less
manpages in alpine
You noted in previous section, that some packages has a "xxx-doc" related.. as explained beforein Alpine Linux:Overview, the system always will be minimalist, and if you wants a manpage of any program on a package of software, always must install the "program" and also "program-doc" related part package.
Take in consideration that in some earlier version of alpine not all package have a doc package yet available.
coreutils libc and utmps in alpine
Some programs like wall(1) depends on a libc feature named "utmp", that cannot be implemented in the libc in a secure way. For this reason, musl (the libc that Alpine uses) does not implement utmp; instead, it provides stubs that do nothing.
That is why programs that use utmp - such as wall, who or w - output nothing but still exit successfully. This is expected, a feature, and cannot be quick-fixed.
Some has pretty solution, by example a utmps login monitoring are only in "edge" repositories, so let's do that for some functionality aware, lest activate edge repository, install temporally software and later deactivating:

cat > /etc/apk/repositories << EOF http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/main http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/community EOF apk update apk add coreutils coreutils-doc cat > /etc/apk/repositories << EOF http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/main http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/community http://dl-cdn.alpinelinux.org/alpine/edge/main http://dl-cdn.alpinelinux.org/alpine/edge/community EOF apk update apk add utmps cat > /etc/apk/repositories << EOF http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/main http://dl-cdn.alpinelinux.org/alpine/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/community EOF apk update
fonts and fonts configuration
Default internal fb fonts (tty console) or xorg fonts (desktops) are enough for defaulters, but if you can't see your language, you need to install the font that has glyphs (little picture) created for it; font-misc-misc are installed with X server so fonts for most languages (Japanese, Korean, Latin, Cyrillic) are already covered except for Arabic, Persian, Thai, Tamil, etc from inspecting the Wikipedia Page left column on languages for article translation. For complete info about fonts in alpine see Fonts configurations and settings in Alpine this section will resume and configure most usefully needs for users:
Those selection will cover most used languages and best fit for many setups:
apk add terminus-font ttf-inconsolata ttf-dejavu font-bitstream-* font-noto font-noto-* ttf-font-awesome font-noto-extra
Those selection will added special support for cirilyc like russian and serbian or similar setups:
apk add font-vollkorn font-misc-cyrillic font-mutt-misc font-screen-cyrillic font-winitzki-cyrillic font-cronyx-cyrillic
Those selection will cover special language for Asiatic like Japanese or similar setups:
apk add terminus-font font-noto font-noto-thai font-noto-tibetan font-ipa font-sony-misc font-daewoo-misc font-jis-misc
Following will added some Chinese partial support fonts setups:
apk add font-isas-misc
Those selection will cover in most manner Arabic, Thai, Ethiopic, Hebrew, Romanian, Persian, Korean Hangul, Greek, Persian, Russian/Slavic Cyrillic, Macedonian/Serbian, Armenian, Georgian, Lao, Devanagari, Urdu (Hindustani as in Northern India and Pakistan), Cherokee, Thaana languajes support for desktops setups:
apk add terminus-font font-bitstream-* font-noto font-noto-extra font-arabic-misc apk add font-misc-cyrillic font-mutt-misc font-screen-cyrillic font-winitzki-cyrillic font-cronyx-cyrillic apk add font-noto-arabic font-noto-armenian font-noto-cherokee font-noto-devanagari font-noto-ethiopic font-noto-georgian apk add font-noto-hebrew font-noto-lao font-noto-malayalam font-noto-tamil font-noto-thaana font-noto-thai
The system font directory is located at /usr/share/fonts
; user font location is at ~/.font
due security. Configurations are reign by X server, using the ~/.Xresources
file as main first reading of.
Configuration are made per user into ~/.fonts.conf
but are XLM made and hard to configure.. more cheap and easy are into the ~/.Xresources
file.
The following will setup for all users a minimal resource usage for fonts.. no antialiasing.. no hint... :
cat > /home/*/.Xresources << EOF Xft.antialias: 0 Xft.rgba: rgb Xft.autohint: 0 Xft.hinting: 1 Xft.hintstyle: hintslight EOF
apk packages for sound base
Currently alsa packages are the minimal for linux Alpine sound, in desktops theres the gstreamer, phonon and pulseaudio frameworks but that's will be managed into the desktops wiki pages:
apk add alsa-utils alsa-utils-doc alsa-lib alsaconf
Alsa service is not started on install, you need to start it and to add it on rc.
rc-service alsa start rc-update add alsa
New users: management of users and logins
When Alpine Linux is first installed by default it comes with the user root with no password set so the first step after boot into alpine fresh install are set a password to the user root, if during isntall was run setup-alpine to change root password, that will be already assigned and can be changed with those setup steps described here. More info in the Setting users wiki page.
Users creation and defaults
Only root can manage users. Creating an account allows it to have it's own $HOME
directory and allows you to limit access to the configuration of the operating system for security reasons. So the following commands will first setup root environment login and then assing a new password:
cat > /root/.cshrc << EOF unsetenv DISPLAY || true HISTCONTROL=ignoreboth EOF cp /root/.cshrc /root/.profile echo "secret_new_root_password" | chpasswd
The remote management cannot be done with root directly by default, due ssh security, so we need to setup an remote connection account to made "su" once connected.
The most recommended it's having a access user here named "remote" and normal general usage user here named "general" for convenience, in the next commands we will setup a very hardened limited environment for any new user and created those two users:
mkdir -p /etc/skel/ cat > /etc/skel/.logout << EOF history -c /bin/rm -f /opt/remote/.mysql_history /bin/rm -f /opt/remote/.history /bin/rm -f /opt/remote/.bash_history EOF cat > /etc/skel/.cshrc << EOF set autologout = 30 set prompt = "$ " set history = 0 set ignoreeof EOF cp /etc/skel/.cshrc /etc/skel/.profile adduser -D --home /opt/remote --shell /bin/ash remote echo "secret_new_remote_user_password" | chpasswd adduser -D --shell /bin/bash general echo "secret_new_general_user_password" | chpasswd
Note that those users are created with minimal settings. Of course you must changed "secret_new_remote_user_password" by a proper password provided by you, also equaly with "secret_new_general_user_password" too.
Users management and system access
But this user will not have enough privileges for a desktop made purposes, Alpine comes with high security so administrator (the root account owner) must perform the management of that user. Take care, for a server made there's no similar procedure!
Management of users can be made with the default busybox, but there's some packages that makes the life easy of the admins, lest use the libuser package now from testing repository:
cat > /etc/apk/repositories << EOF http://mirror.math.princeton.edu/pub/alpinelinux/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/main http://mirror.math.princeton.edu/pub/alpinelinux/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/community http://mirror.math.princeton.edu/pub/alpinelinux/edge/testing/ EOF apk update apk add libuser cat > /etc/apk/repositories << EOF http://mirror.math.princeton.edu/pub/alpinelinux/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/main http://mirror.math.princeton.edu/pub/alpinelinux/v$(cat /etc/alpine-release | cut -d'.' -f1,2)/community EOF apk update touch /etc/login.defs touch /etc/default/useradd
Now we can changes some defaults and added to proper groups to access devices or perform connections so, those are the recommended groups where the user must have in:
for u in $(ls /home); do for g in disk lp floppy audio cdrom dialout video netdev games users; do addgroup $u $g; done;done
- disk:x:6:root,adm Only if need usage vith virtual machines and access to other partitions over new disks for
- lp:x:7:lp IF will need to use printing services and printers management
- floppy:x:11:root Backguard compatible group, use only if need access to external special devices
- audio:x:18: Need for audio listening and management of sound volumes as normal user
- cdrom:x:19: For access to disck writers and mounting DVD, BR or CD rom disk as normal user
- dialout:x:20:root Need for dial private connections and use of modems as normal users
- tape:x:26:root Need have into this if plan to use special devices for backup.. rarelly in no servers
- video:x:27:root For usage of cameras, mor thant one GPU special features, as normal user
- netdev:x:28: For network connections management as normal user
- kvm:x:34:kvm Only if as normal user will manage graphically virtual machines.. rarelly on no servers
- games:x:35: Need if you want to play games also specially need if will share score between users
- cdrw:x:80: To write RW-DVD, RW-BR or RW-CD disk on a disk writing device
- apache:x:81: Need if you will perfom development as normal user and want to publish locally on web server
- usb:x:85: Need to access to special usb devices, deprecated group
- users:x:100:games If you plan to used common files for all users, mandatory as desktop usage
Now we have libuser also can change default shell:
- If you want to change the current user's shell, log in as that user and then inside their terminal session execute::
lchsh
- If you want to change a different user's shell, run as administration or as root:
lchsh general
Where "general" was the name of a created user login in previous sections.
Continue to Desktop
Before you continue, you must have at least already done the previously described steps in the section New users: common needed package to install!

Alpine package management behavior
This section are not for new users, please go next to Alpine newbie desktops or Alpine Newbies: Xorg and Openbox if you only want to setup your system.
The programs, the software installed to Alpine comes from two places, a repository with the following structure: http://<host>/alpine/<version>/<brach>
(an URl that can be invoked with apk listed in the /etc/apk/repositories
file) and original upstream sources (those compiled as Unix-like traditional way).
As new user you can read the Alpine newbie apk packages page.. but please read the rest of this section to introduce to:
Alpine Software Packages
Alpine software repositories have main packages and contributions made:
- About the main packages: Main packages are the Alpine package software that have direct support and updates from the Alpine core and main team, also have official special documentation. Are always available for all releases and will have almost substitutions if some are not continued from upstream. Commonly those packages are selected due their responsibility and stability respect upstream availability.
- About the contribution ones: User package contribution repositories are those made by users in team with the official developers and well near integrated to the Alpine packages. Those have supported by those user contributions and could end if the user also ends respect with Alpine work, by example could not have substitution in next release due lack of support by upstream author.
Alpine APK user resources
Alpine new users have two resources for the packaging management, the https://pkgs.alpinelinux.org/packages page for search friendly way, and the Alpine newbie apk packages page that describes how to use the apk-tool easy.
Alpine APK quick infrastructure
Software packages for Alpine Linux are digitally signed tar.gz archives containing programs, configuration files, and dependency metadata. They have the extension .apk
, and are often called "a-packs".
The apk command are located at /sbin/apk
, admin and manages the getting of the packages of software, it uses /etc/apk/
place for the configurations files, and stores all downloaded "a-packs" files in /etc/apk/cache
from the repositories before unpacks and put the package files compiled into the installed system.
