## Script setup-alpine
This script is the main install program for Alpine linux, only can run as root.
**Log in** as **root** and press enter. No password will be asked for if
you're running from the boot image.
![](https://wiki.alpinelinux.org/images/4/4f/Installation-alpine-alpine-setup-3-root-login.png)
#### Environemnt variables before run
At the bash prompt you can export those environment variables that the scripts
will handle it automatically:
> **Note** The followin variables are only handle by `setup-disk` and `setup-bootable`
* `BOOTFS` The filesystem to use on `/boot`, defaults to `ext4`, also
allows `ext2`, `ext3`, (flat) `btrfs`, `xfs`.
* `BOOTLOADER` The bootloader to use. Defaults to `syslinux` until 3.12 and
since 3.14 defaults to `grub`, unless [UEFI](alpine-boot-uefi-bios.md) is used wil be forced to.
* `BOOTSIZE` The size of `/boot` partition when the scripts try to automatically
created, its handle in Megs only.
* `DISKLABEL` The type of partition table to use. Defaults to `dos`, unles `grub`
and [UEFI](alpine-boot-uefi-bios.md) is used, in which case `gpt` is setup.
* `ROOTFS` The filesystem to use on `/`, defaults to `ext4`, also allows `ext2`,
`ext3`, (flat) `btrfs` and `xfs`.
* `USE_EFI` Enable this to force using UEFI](alpine-boot-uefi-bios.md), so then
automatically the bootloader will be `grub` and partition wil be `gpt` then.
> **Note** The following variables one only supported by the `setup-alpine` and others
* `KEYMAPOPTS` setup the keymap layout pair for `setup-keymap`, by example `="us us"`
* `HOSTNAMEOPTS` setup and parse for `setup-hostname` script, by example `="-n venenux"`
* `TIMEZONEOPTS` setup the timezone for `setup-timezone` script like `="-z UTC"`
* `PROXYOPTS` setup and parse option to `setup-proxy` script like `="http://webproxy:8080"`
* `DISKOPTS` setup and parse option to `setup-disk` script like `="-m data /dev/sda"`
> **Warning** Check the complete support of scripts from [Setup scripts](#setup-scripts) section.
#### Running setup alpine script
Run the **setup-alpine** script as shown in the image:
![](https://wiki.alpinelinux.org/images/7/75/Installation-alpine-alpine-setup-4-setup-scripts.png)
The script interactively walks the user through executing several auxiliary setup-* scripts, in the order shown below.
The bracketed options represent example configuration choices, formatted as they
may be supplied when manually calling the independing [setup scripts](#setup-scripts),
or using a `setup-alpine` "answerfile" using the variable environments prevously cited.
* `-h` Shows the up-to-date usage help message.
* `-c <answerfile>` Create new answerfile with default choices, you then edit and tune up.
* `-f <answerfile>` Use the new created answerfile, which may override some or all of the prompts.
* `-q` Run in "quick mode", will setup less question adn assumes defaults for rest.
##### Select keyboard layout
Choose your **keyboard layout**. If you don't know your keyboard layout,
choose **us**. Typically, for a Latin American environment, *es* is
enough. For Russian (and maybe Cyrilic) *ru* is sufficient.
![](https://wiki.alpinelinux.org/images/0/04/Installation-alpine-alpine-setup-4-setup-scripts-1-languaje-2.png)
> **Note** check `setup-keymap` script at [Setup scripts](#setup-scripts) section.
##### Select keyboard variant
Choose your **keyboard variant**. If you don't know your keyboard
variant, choose the default from the list. For example, the typical
Latin American keymap is *es-winkeys*.
![](Installation-alpine-alpine-setup-4-setup-scripts-1-languaje-2.png "Installation-alpine-alpine-setup-4-setup-scripts-1-languaje-2.png")
> **Note** check `setup-keymap` script at [Setup scripts](#setup-scripts) section.
##### Enter system hostname
Host name, which will be the name of your computer. using **localhost**
is enough and recommended for testing purposes because permits apply
mostly to how-tos and tutorials on the wiki pages.
![](Installation-alpine-alpine-setup-5-setup-scripts-hostname.png "Installation-alpine-alpine-setup-5-setup-scripts-hostname.png")
> **Note** check `setup-hotname` script at [Setup scripts](#setup-scripts) section.
##### Initialize network cards
Choose your network card. Typically, you can just go with the default
(press enter), a second question will ask about any other configuration.
Type "no" then press enter to bypass the step to property set up after
installation finished property.
![](Installation-alpine-alpine-setup-6-setup-scripts-networking.png "Installation-alpine-alpine-setup-6-setup-scripts-networking.png")
**IMPORTANT NOTE**: mostly in x86 and x64 ISO images we can let
configurations for later, cos at the most modern the network card, the
lest supported or still not well tested. Just type `done` and press
enter. If you configured the wired interface, another question will be
asked, **use dhcp?** Most people will use DHCP, so press enter again. If
you have Internet connection from ISP, most settings are just DHCP, so
all will be configured automatically.
> **Note** check `setup-networking` script at [Setup scripts](#setup-scripts) section.
> **Warning** check [../tutorials/alpine-tutorial-wifi-routering.md](../tutorials/alpine-tutorial-wifi-routering.md)
##### Initialize network DNS
The DNS will be automatically detected, if not, you will be asked ask
for the server addresses. Type "" (empty string) for domain, then press
enter. Later you can change it to `8.8.8.8` (or the DNS server address
of your choice) as shown in the picture. Press enter to go to the next
question:
![](Installation-alpine-alpine-setup-7-setup-scripts-dns.png "Installation-alpine-alpine-setup-7-setup-scripts-dns.png")
> **Note** check `setup-dns` script at [Setup scripts](#setup-scripts) section.
##### Changing the root password
Next a root password must be defined. You'll need to type it twice for
confirmation as the picture shows. If it's too short you will get a
warning, but your password will still work. Just retype it and go.
Note: **when you type, NO chars will be shown**.
![](Installation-alpine-alpine-setup-8-setup-scripts-root-password.png "Installation-alpine-alpine-setup-8-setup-scripts-root-password.png")
##### Which timezone to choose?
Select a timezone, just press enter to use `UTC` when perform a single
installation.
![](Installation-alpine-alpine-setup-9-setup-scripts-timezone.png "Installation-alpine-alpine-setup-9-setup-scripts-timezone.png")
> **Note** check `setup-timezone` script at [Setup scripts](#setup-scripts) section.
##### Proxy chooser
Then setup script will ask for proxy chooser.. just type `none` and then
press enter
![](Installation-alpine-alpine-setup-9-setup-scripts-proxy.png "Installation-alpine-alpine-setup-9-setup-scripts-proxy.png")
> **Note** check `setup-proxy` script at [Setup scripts](#setup-scripts) section.
##### Enter mirror number
Then setup script will ask for repository mirror chooser.. just type
`done` and then press enter, this will be configure many times later
during usage of the system. Almost any tutorial of newbie pages will
explain detailed so lest bypass using "done".
![](Installation-alpine-alpine-setup-9-setup-scripts-repository-mirror.png "Installation-alpine-alpine-setup-9-setup-scripts-repository-mirror.png")
> **Note** check `setup-apkrepos` script at [Setup scripts](#setup-scripts) section.
##### Which ssh server?
Installing an SSH server enables you to manage your machine remotely.
OpenSSH is what the big distros use. Dropbear is a tiny SSH replacement.
Recommended to type **openssh** and then press enter, because you able
to connect using command line from Unix-like systems also is the offline
available in all alpine installer images.
![](Installation-alpine-alpine-setup-9-setup-scripts-ssh.png "Installation-alpine-alpine-setup-9-setup-scripts-ssh.png")
> **Note** check `setup-sshd` script at [Setup scripts](#setup-scripts) section.
##### Which NTP client to run?
This is for time sync. Press enter to use the image offline. It can be
changed after installation.
![](Installation-alpine-alpine-setup-9-setup-scripts-time-ntp.png "Installation-alpine-alpine-setup-9-setup-scripts-time-ntp.png")
> **Note** check `setup-ntp` script at [Setup scripts](#setup-scripts) section.
#### Script setup-disk choose the target device
This script its called at last from `setup-alpine`, it will mount a target device,
wil try to partitioned and copy the data to the target device.
Those are the questions that wil be prompt if you just invoke by default:
* **disk to use** "setup-disk" first question is to choose the disk destination ..
commonly `sda` (`/dev/sda`) are the hard disk and `sdb` the USB boot or CD/DVD image.
* **mode to use** to choose the mode to install, `sys` for desktop/server, `data` for
live mixed mode, for more information check [data modes](#data-modes) section.
* **erase the disk** This question will be promtp only if the disk already have
partitions, if you choose `y` will erase hole device and make new partitions.
* **formatin and coping** later the script will copy all the data to the target
device, and the if you invoke from `setup-alpine` will call `setup-bootable` too.

![](https://wiki.alpinelinux.org/images/a/a6/Installation-alpine-alpine-setup-9-setup-disk-3-7end.png)
Check the [setup disk](#setup-disk) next section for specific script options
After a while the installation will finish and alpine can be booted
## Setup scripts
#### setup-hostname
`setup-hostname [-h] [-n hostname]`
#### setup-interfaces
`setup-interfaces [-i < interfaces-file]`
#### setup-dns
`setup-dns [-h] [-d domain name] [-n name server]`
#### setup-disk
This script its invoked by `setup-alpine` and as the same it support the
following enviroment variables:
* `DEFAULT_DISK` The device disk to use as target installation, default to `=none`
* `BOOTFS` The filesystem to use on `/boot`, defaults to `ext4`, also
allows `ext2`, `ext3`, (flat) `btrfs`, `xfs`.
* `BOOTLOADER` The bootloader to use. Defaults to `syslinux` until 3.12 and
since 3.14 defaults to `grub`, unless [UEFI](alpine-boot-uefi-bios.md) is used wil be forced to.
* `BOOTSIZE` The size of `/boot` partition when the scripts try to automatically
created, its handle in Megs only.
* `DISKLABEL` The type of partition table to use. Defaults to `dos`, unles `grub`
and [UEFI](alpine-boot-uefi-bios.md) is used, in which case `gpt` is setup.
* `ROOTFS` The filesystem to use on `/`, defaults to `ext4`, also allows `ext2`,
`ext3`, (flat) `btrfs` and `xfs`.
* `USE_EFI` Enable this to force using UEFI](alpine-boot-uefi-bios.md), so then
automatically the bootloader will be `grub` and partition wil be `gpt` then.
Those are the most working options to parse to the script, only supported if you
runs directly, not if you parse it to `setup-alpine` script:
* `-m data | sys` set the install mode target; check the [data modes](#data-modes) section
* `-q` Exit quietly if no disks are found
* `-v` Verbose mode
#### Data modes
In "sys" mode, it's an installer, it permanently installs Alpine on the hole target partition,
in "data" mode, it provides a larger and persistent `/var` volume on the hole target partition.
##### data - Data Disk Mode
This mode runs OS from system RAM install media, but using `swap` and `/var` persistent.
If this mode is selected, script creates two partitions on the selected storage
device asked by `setup-disk` firts question, `/var` and `swap` respectivelly.
this setup is used for special server deploys or minimal devices deploys like ARM devices.
##### sys - System Disk Mode
This is a traditional hard-disk install.
If this mode is selected, script creates three partitions on the selected storage
device asked by `setup-disk` firts question, `/boot`, `/` and `swap` respectivelly.
this setup is used for generic desktop and development machines, or server bare metal deploys.
##### ram - Diskless Mode
This means the entire operating system with all applications are first loaded into RAM and
then only run from there. This is the method already used to boot the .iso installation images,
however setup-alpine can also configure the installed system to continue to boot like this
if "disk=none" is specified.
Custom configurations and package installations may optionally still be preserved or "persist"
across reboots by using the Alpine local backup tool lbu.
#### setup-timezone
`setup-timezone [-z UTC | -z America/New_York | -p EST+5]`
#### setup-proxy
`setup-proxy [-hq] [PROXYURL]`
#### setup-apkrepos
`setup-apkrepos [-fhr] [REPO...]`
#### setup-sshd
`setup-sshd [-h] [-c dropbear|openssh|none]`
#### setup-ntp
`setup-ntp [-h] [busybox|openntpd|chrony|none]`
#### setup-bootable
Setup boot loaders, it's not invoked directly by `setup-alpine` but
it triggers by `setup-disk` if you choose sys or data mode.
`setup-bootable [-usfk] source [dest]`
* The argument source can be a directory or an ISO (will be mounted to MNT or /mnt)
or a URL (will be downloaded with WGET or wget).
* The argument dest can be a directory mountpoint, or will default
to `/media/usb` if not supplied.
Those are the options:
* `-k` Keep alpine_dev in syslinux.cfg; otherwise, replace with UUID.
* `-u` Upgrade mode: keep existing syslinux.cfg and don't run syslinux
* `-f` Overwrite syslinux.cfg even if -u was specified.
* `-s` Force the running of syslinux even if -u was specified.
* `-v` Verbose mode
