Installation

From Alpine Linux
(Redirected from Installing Alpine)
Jump to: navigation, search

While Alpine Linux is often used as base image for linux containers, it can of course be also installed on bare metal machine as well. That is the focus of this document.

So remenber, this first document is a general use case, Alpine newbie install manual is the main reference to more ways to perform installation or permanent data saving on a device, for others hardware and use case


Quick Requirements

Nearly any hardware should run Alpine Linux but the following basic requirements are recommended:

  • At least 128MB of RAM for server without GUI, or at least 1.6GB for graphical desktop
  • At least 1GB storage device for server without GUI, or at least 10GB for graphical desktop with web browsing

For more information, see Requirements.

Installation : setup-alpine : booting process until login prompt

Installation Overview

The following steps are brief and intended for the common case; for complete info and other architectures, Alpine newbie install manual is the main reference to more ways to perform installation or permanent data saving on a device, for others hardware and use cases.

1. Download the installation image

You need to acquire installation image, usually from [1]. Most likely you will want the standard edition. Make sure you download the image for correct architecture.

2. Create the installation medium

Either you can burn the image onto CD/DVD, you use usb stick for the installation.

Under linux, you can use the dd for that:

dd if=<source iso> of=<target device> bs=4M; sync

Make sure that the device does not include partition number, so example from my machine:

dd if=~/Downloads/alpine-standard-3.10.2-x86_64.iso of=/dev/sdb bs=4M

The target device will be erased, so make sure you use something without any data you do not want to lose.

3. Boot and install process

Log in as the user root and execute setup-alpine and answer all the questions asked. Quick step-by-step walkthrough (go read setup-alpine for more in-depth explanation):

Installation : setup-alpine : complete process single install
Keyboard layout and variant

As you would expect, this is keyboard layout you want. If you are not sure, answering us to both layout and variant will get you started and you can change it later.

System hostname

Pick the name of your computer, while not mandatory, something unique if prefered. Or you can just use localhost if you do not care.

Network configuratinon

You will be asked which network interface you want to configure, if you are not sure, picking the offered default would likely work. Once selected, you will be asked Ip address for XXX?, you can either assign an IP address or write dhcp, which will mean take configuration from the network (the dhcp works great for home networks where you do not care about IP of your machine).

Assuming you decided to configure network yourself with IP address, you will also be asked for netmask, gateway, dns domain name and dns server IP. Correct values for there are beyond the scope of this document, please refer to your network administrator for guidance instead.

Password for root

Well this one is obvious.

Timezone

For servers, it is common to use UTC, for non-server machines, your local timezone should be likely used. Notice that you can use ? to list the timezone.

HTTP/FTP Proxy

Most likely default (none) is the correct choice.

NTP client

Which client to use for keeping the system clock in sync, default works for most people.

Mirror

Pick mirror from which to download updates, 1 is CDN backed by Fastly, so reasonable choice for most people.

SSH server

Which SSH server do you want to configure on your machine. If you know that you will not connect to your machine remotely (most laptops for example), none should be used. Otherwise, the default (openssh) is a good pick.

Disk setup

Here your can pick the device to install the system on and also the mode in which it should be installed. For overview of the modes, see this. If you are not sure or just starting up, sys is likely what you want, it is the same mode that other distributions use for installation.

All data on the chosen device will be erased!

Reboot

After the script finishes installing the system, it will tell you to reboot. Note that:

  • If the configured runtime mode was "sys", then remove the initial installation media to boot the newly installed system.
  • If the configured runtime mode was "data", then keep the installation media inserted to boot the newly installed system.

Then execute reboot and once the machine restarts and finishes booting up, you should see login prompt of your new Alpine Linux installation.

The installation script only installs the base operating system. Applications such as a web server, mail server, desktop environment, or web browser are not installed and root is the only normal user. For instructions on proceeding after installation, please see Tutorials_and_Howtos Post-Install section.
