| = About =
| | [[User:Ncopa/Install Handbook]] |
| Alpine Linux is an x86 Linux distribution suitable for firewalls, routers, VPN gateways, lightweight servers (http, sql, mail), resque livecd or other embedded devices.
| |
|
| |
|
| == Lightweight ==
| | [[User:Ncopa/buildmsg]] |
| Alpine is based on and [http://busybox.org busybox] (and are thus not a GNU/Linux distro).
| |
|
| |
|
| The base system, excluding the kernel, is less than 2MB. That includes:
| | [[User:Ncopa/Alpine Mirror with MQTT]] |
| * the C library runtime, [http://uclibc.org uclibc]
| |
| * standard tools from [http://busybox.net busybox] (cp, ls, mv, wget, iproute, nc etc)
| |
| * package manager, apk-tools
| |
| * openrc init system
| |
| | |
| == Proactive security ==
| |
| The default kernel is patched with the grsecurity patches and provides features like:
| |
| * Address Space Randomization Layout
| |
| * Memeory protection
| |
| | |
| Alpine Linux is a run-from RAM linux distribution. Its original target was small appliances like routers, VPN gateways, or embedded x86 devices. However, it supports hosting other Linux guest OSes under [http://linux-vserver.org/ VServer] control, making it an attractive hosting solution as well. | |
| | |
| It can boot from a 1GB USB stick, CDrom, or hard drive. Packages compiled against [http://www.uclibc.org/ uClibc] are pulled into RAM for execution. All packages are compiled with [http://www.grsecurity.net/ grsecurity patches] and [http://en.wikipedia.org/wiki/Stack-smashing_protection SSP] to provide a secure runtime environment.
| |
| The lbu backup system stores all changes to /etc (and custom changes) to the boot media, making system disaster recovery brain-dead simple.
| |
| | |
| = APKBUILD Reference =
| |
| APKBUILDs are scripts to build alpine packages using the [[abuild]] tool.
| |
| | |
| == Variables ==
