Rain1: escape the 's so that wiki doesn't interpret it as a link

An upgrade of Alpine Linux from a stable version to the rolling development version, ''edge'' can be done in a few simple steps. (These instructions assume that Alpine Linux is installed to a hard drive, rather than run-from-RAM.)

To begin, you need to update your {{Path|/etc/apk/repositories}} file. Here are some shortcuts for doing so:
:* Launch {{Cmd|setup-apkrepos}} Enter {{Key|e}} to edit {{Path|/etc/apk/repositories}}. Change the version number (such as <var>v3.2</var>) to '''edge'''.
:* Or, edit the file in place: {{Cmd|sed -i -e 's/<var>v[[:digit:]]\.[[:digit:]]</var>/<var>edge</var>/g' /etc/apk/repositories}}

The result should look like this:
{{Cat|/etc/apk/repositories|...
http://dl-3.alpinelinux.org/alpine/edge/main}}



Next, upgrade all your packages in one shot: {{Cmd|apk upgrade --update-cache --available}}
The <code>--available</code> switch is used to force all packages to be upgraded, even if they have the same version numbers. Sometimes changes in musl-libc have required doing this.

{{Note|You will need to restart any services that have been upgraded to begin using the upgraded versions. If the kernel is upgraded, you will need to reboot to begin using the upgraded version:
{{Cmd|sync
reboot}}
}}

To check your current release: {{Cmd|cat /etc/alpine-release}} You will see the build date attached to the release.

Default applications

Rain1: Correct the mupdf path

To change the default application associated with a filetype you must use the xdg-mime command and point to the desired desktop file (if it doesn't exist, you must create one).

= Example =
In the following example we want to make mupdf the default command to open pdf files.
First you need to create a desktop file, because mupdf doesn't provide one.
{{Cmd|$ cat > ~/.local/share/applications/mupdf.desktop}}
<pre>
[Desktop Entry]
Type=Application
Terminal=false
Exec=/usr/bin/mupdf-gl
Name=mupdf
</pre>
Then you must use xdg to associate the desktop file with the pdf extension.
{{Cmd|$ xdg-mime default mupdf.desktop application/pdf}}
That's all.

Alpine configuration management scripts

2016-03-24T11:35:49Z

Rain1: case consistency

This page summarizes the low-level behavior of the {{Path|/sbin/setup-*}} scripts on the Alpine ISO (and in a normal Alpine install).

== setup-alpine ==

For a higher-level walkthrough (using the "sys" installmode), see [[Install to disk|Basic HDD install]].

This script accepts the following command-line switches (you can run <code>setup-alpine -h</code> to see a usage message).

{{Define|-a|Create an overlay file: this creates a temporary directory and saves its location in ROOT; however, the script doesn't export this variable so I think this feature isn't currently functional.}}
;-c <var>answerfile</var>
:Create a new "answerfile", with default choices. You can edit the file and then invoke <code>setup-alpine -f <var>answerfile</var></code>.
;-f <var>answerfile</var>
:Use an existing "answerfile", which may override some or all of the interactive prompts.
{{Define|-q|Run in "quick mode." See below for details.}}

The script's behavior is to do the following, in order. Bracketed options represent extra configuration choices that can be supplied when running the auxiliary setup scripts manually, or by supplying an "answerfile".

# <code>setup-keymap</code> [us us]
# [[#setup-hostname|setup-hostname]] [-n alpine-test]
# [[#setup-interfaces|setup-interfaces]] [-i < interfaces-file]
# <code>/etc/init.d/networking --quiet start &</code>
# if none of the networking interfaces were configured using dhcp, then: [[#setup-dns|setup-dns]] [-d example.com -n "8.8.8.8 [...]"]
# set the root password
# if not in quick mode, then: [[#setup-timezone|setup-timezone]] [-z UTC | -z America/New_York | -p EST+5]
# enable the new hostname (<code>/etc/init.d/hostname --quiet restart</code>)
# add <code>networking</code> and <code>urandom</code> to the '''boot''' rc level, and <code>acpid</code> and <code>cron</code> to the '''default''' rc level, and start the '''boot''' and '''default''' rc services
# extract the fully-qualified domain name and hostname from {{Path|/etc/resolv.conf}} and <code>hostname</code>, and update {{Path|/etc/hosts}}
# [[#setup-proxy|setup-proxy]] [-q <nowiki>"http://webproxy:8080"</nowiki>], and activate proxy if it was configured
# <code>setup-apkrepos</code> [-r (to select a mirror randomly)]
# if not in quick mode, then: [[#setup-sshd|setup-sshd]] [-c openssh | dropbear | none]
# if not in quick mode, then: <code>setup-ntp</code> [-c chrony | openntpd | busybox | none]
# if not in quick mode, then: <code>DEFAULT_DISK=none</code> [[#setup-disk|setup-disk]] <code>-q</code> [-m data /dev/sda]
# if installation mode selected during setup-disk was "data" instead of "sys", then: <code>setup-lbu</code> [/media/sdb1]
# if installation mode selected during setup-disk was "data" instead of "sys", then: <code>setup-apkcache</code> [/media/sdb1/cache | none]

== setup-hostname ==

:<code>setup-hostname</code> [-h] [-n hostname]

Options:

'''-h''' <var>Show help</var>

'''-n''' <var>Specify hostname</var>

This script allows quick and easy setup of the system hostname by writing it to {{Path|/etc/hostname}}. The script prevents you from writing an invalid hostname (such as one that used invalid characters or starts with a '-' or is too long).
The script can be invoked manually or is called as part of the <code>setup-alpine</code> script.

== setup-interfaces ==
{{Cmd|setup-interfaces [-i < <var>interfaces-file</var>]}}

Note that the contents of <var>interfaces-file</var> has to be supplied as stdin, rather than naming the file as an additional argument. The contents should have the format of {{Path|/etc/network/interfaces}}, such as:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
hostname alpine-test

== setup-dns ==

:<code>setup-dns</code> [-h] [-d domain name] [-n name server]

Options:

'''-h''' <var>Show help</var>

'''-d''' <var>specify search domain name</var>

'''-n''' <var>name server IP</var>

The setup-dns script is stored in {{Path|/sbin/setup-dns}} and allows quick and simple setup of DNS servers (and a DNS search domain if required). Simply running <code>setup-dns</code> will allow interactive use of the script, or the options can be specified.

The information fed to this script is written to {{Path|/etc/resolv.conf}}

Example usage: {{Cmd|setup-dns -d example.org -n 8.8.8.8}}

Example {{Path|/etc/resolv.conf}}:

search example.org
nameserver 8.8.8.8

It can be run manually but is also invoked in the <code>setup-alpine</code> script unless interfaces are configured for DHCP.

== setup-timezone ==
:<code>setup-timezone</code> [-z UTC | -z America/New_York | -p EST+5]

Can pre-select the timezone using either of these switches:

'''-z''' <var>subfolder of</var> {{Path|/usr/share/zoneinfo}}

'''-p''' <var>POSIX TZ format</var>

== setup-proxy ==
:<code>setup-proxy</code> [-hq] [PROXYURL]

Options:

'''-h''' <var>Show help</var>

'''-q''' <var>Quiet mode</var> prevents changes from taking effect until after reboot

This script requests the system proxy to use in the form <code>http://<proxyurl>:<port></code> for example:
<code>http://10.0.0.1:8080</code>

To set no system proxy use <code>none</code>.
This script exports the following environmental variables:

<code>http_proxy=$proxyurl</code>

<code>https_proxy=$proxyurl</code>

<code>ftp_proxy=$proxyurl</code>

where <code>$proxyurl</code> is the value input.
If <code>none</code> was chosen then the value it is set to a blank value (and so no proxy is used).

== setup-sshd ==

:<code>setup-sshd</code> [-h] [-c choice of SSH daemon]

Options:

'''-h''' <var>Show help</var>

'''-c''' <var>SSH daemon</var> where SSH daemon can be one of the following:

<code>openssh</code> install the {{Pkg|openSSH}} daemon

<code>dropbear</code> install the {{Pkg|dropbear}} daemon

<code>none</code> Do not install an SSH daemon

Example usage: {{Cmd|setup-sshd -c dropbear}}

The setup-sshd script is stored in {{Path|/sbin/setup-sshd}} and allows quick and simple setup of either the OpenSSH or Dropbear SSH daemon & client.
It can be run manually but is also invoked in the <code>setup-alpine</code> script.

== setup-disk ==

:<code>DEFAULT_DISK=none setup-disk -q</code> [-m data | sys] [<var>mountpoint directory</var> | /dev/sda ...]

This script accepts the following command-line switches:

;-k <var>kernel flavor</var>
;-o <var>apkovl file</var>
:Restore system from <var>apkovl file</var>
;-m data | sys
:Don't prompt for installation mode. With '''-m data''', the supplied devices are formatted to use as a {{Path|/var}} volume.
{{Define|-r|Use RAID1 with a single disk (degraded mode)}}
{{Define|-L|Create and use volumes in a LVM group}}
;-s <var>swap size in MB</var>
:Use 0 to disable swap
{{Define|-q|Exit quietly if no disks are found}}
{{Define|-v|Verbose mode}}

The script also honors the following environment variables:

<code>BOOT_SIZE</code>
:Size of the boot partition in MB; defaults to 100. Only used if '''-m sys''' is specified or interactively selected.

<code>SWAP_SIZE</code>
:Size of the swap volume in MB; set to 0 to disable swap. If not specified, will default to twice RAM, up to 4096, but won't be more than 1/3 the size of the smallest disk, and if less than 64 will just be 0. Only used if '''-m sys''' is specified or interactively selected.

<code>ROOTFS</code>
:Filesystem to use for the / volume; defaults to ext4. Only used if '''-m sys''' is specified or interactively selected. Supported filesystems are: ext2 ext3 ext4 btrfs.

<code>BOOTFS</code>
:Filesystem to use for the /boot volume; defaults to ext4. Only used if '''-m sys''' is specified or interactively selected. Supported filesystems are: ext2 ext3 ext4 btrfs.

<code>VARFS</code>
:Filesystem to use for the /var volume; defaults to ext4. Only used if '''-m data''' is specified or interactively selected. Supported filesystems are: ext2 ext3 ext4 btrfs.

<code>SYSROOT</code>
:Mountpoint to use when creating volumes and doing traditional disk install ('''-m sys'''). Defaults to {{Path|/mnt}}.

<code>MBR</code>
:Path of MBR binary code, defaults to {{Path|/usr/share/syslinux/mbr.bin}}.



=== Partitioning ===

If you have complex partitioning needs, you can partition, format, and mount your volumes manually, then just supply the root mountpoint to <code>setup-disk</code>. Doing so implicitly behaves as though '''-m sys''' had also been specified.

See [[Setting up disks manually]] for more information.

==== RAID ====
<code>setup-disk</code> will automatically build a RAID array if you supply the '''-r''' switch, or if you specify more than one device. The array will always be [https://en.m.wikipedia.org/wiki/Standard_RAID_levels#RAID_1 RAID1] (and [https://raid.wiki.kernel.org/index.php/RAID_superblock_formats#The_version-0.90_Superblock_Format --metadata=0.90]) for the /boot volumes, but will be [https://en.m.wikipedia.org/wiki/Standard_RAID_levels#RAID_5 RAID5] (and [https://raid.wiki.kernel.org/index.php/RAID_superblock_formats#The_version-1_Superblock_Format --metadata=1.2] for non-boot volumes when 3 or more devices are supplied.

If you instead want to build your RAID array manually, see [[Setting up a software RAID array]]. Then format and mount the disks, and supply the root mountpoint to <code>setup-disk</code>.

==== LVM ====
<code>setup-disk</code> will automatically build and use volumes in a LVM group if you supply the '''-L''' switch. The group and volumes created by the script will have the following names:

* volume group: '''vg0'''
* swap volume: '''lv_swap''' (only created when swap size > 0)
* root volume: '''lv_root''' (only created when '''-m sys''' is specified or interactively selected)
* var volume: '''lv_var''' (only created when '''-m data''' is specified or interactively selected)

The '''lv_var''' or '''lv_root''' volumes are created to occupy all remaining space in the volume group.

If you need to change any of these settings, you can use <code>vgrename</code>, <code>lvrename</code>, <code>lvreduce</code> or <code>lvresize</code>.

If you instead want to build your LVM system manually, see [[Setting up Logical Volumes with LVM]]. Then format and mount the disks, and supply the root mountpoint to <code>setup-disk</code>.



== setup-bootable ==
This is a standalone script; it's not invoked by <code>setup-alpine</code> but must be run manually.

Its purpose is to create media that boots into tmpfs by copying the contents of an ISO onto a USB key, CF, or similar media.

For a higher-level walkthrough, see [[Create a Bootable USB#Creating_a_bootable_Alpine_Linux_USB_Stick_from_the_command_line|Creating a bootable Alpine Linux USB Stick from the command line]].

This script accepts the following arguments and command-line switches (you can run <code>setup-bootable -h</code> to see a usage message).

{{Cmd|setup-bootable <var>source</var> [<var>dest</var>]}}

The argument <var>source</var> can be a directory or an ISO (will be mounted to <code>MNT</code> or {{Path|/mnt}}) or a URL (will be downloaded with <code>WGET</code> or <code>wget</code>). The argument <var>dest</var> can be a directory mountpoint, or will default to {{Path|/media/usb}} if not supplied.

{{Define|-k|Keep alpine_dev in {{Path|syslinux.cfg}}; otherwise, replace with UUID.}}
{{Define|-u|Upgrade mode: keep existing {{Path|syslinux.cfg}} and don't run <code>syslinux</code>}}
{{Define|-f|Overwrite {{Path|syslinux.cfg}} even if '''-u''' was specified.}}
{{Define|-s|Force the running of <code>syslinux</code> even if '''-u''' was specified.}}
{{Define|-v|Verbose mode}}

The script will ensure that <var>source</var> and <var>dest</var> are available; will copy the contents of <var>source</var> to <var>dest</var>, ensuring first that there's enough space; and unless '''-u''' was specified, will make <var>dest</var> bootable.



== setup-xorg-base ==
This is a standalone script; it's not invoked by <code>setup-alpine</code> but must be run manually.

Installs the following packages: <code>xorg-server xf86-video-vesa xf86-input-evdev xf86-input-mouse xf86-input-keyboard udev</code>.

Additional packages can be supplied as arguments to <code>setup-xorg-base</code>. You might need, for example, some of: <code>xf86-input-synaptics xf86-video-<var>something</var> xinit</code>. For Qemu, see [[Qemu#Using_Xorg_inside_Qemu|Qemu]]. For Intel GPUs, see [[Intel Video]].
