Introduction

How mature is Raspberry Pi (RPI). A brief overview.

What is Raspberry Pi

It is a minimalist computer built for ARMv6 architecture. More information about this project and technical specification.

Installing Arch Linux ARM

In this manual will describe only essential moments for different RPI. Other procedures are the same instructions for ArchLinux. The only exception is the basic initialization and installation of equipment. It is further assumed that the configuration is performed on a machine running Archlinux.

Backup Cards

If you own an official card provided with your RPI (for example) recommend before installing Arch ARM Linux to backup using dd. The path must be specified to the device /dev/sdX not for another partition /dev/sdc1

# dd if=/dev/sdX of=$HOME/backup_RPi.img
Note: There is a bit copy of the card. The resulting file is the same size as your card.
Note: card may not be installed.
Warning: Bad parameters can damage your data.

Installation

Installation is similar to backing card. Download the image file from Arch Linux ARM

# dd bs=1M if=/path/to/archlinux.img of=/dev/sdX

After inserting the card into the slot on the PPi should boot the base system Arch Linux ARM.

Home

The downloaded image file is approximately 2 gigabytes of which is /boot 94 megabytes and / 1.8 gigabytes. If you used a larger card to 2GB, so I recommend the rest of the card to connect as /home (or /usr). Clearance must be formatted using the example Gparted. At the first possible opportunity (after booting RPI or after mounting the card in the computer) need to be adjusted /etc/fstab

# sudo vim /etc/fstab

For example, add

/dev/mmcblk0p3 / home ext4 defaults 0 0

The first operation

Summary of the official procedure:

Remote SSH access

If you do not use the HDMI output RPI and you will access the device using SSH, the following applies. Root pasword is: root. I recommend to perform key exchange SSH_Keys.

$ ssh root@192.168.1.123 (Use your Ip RPI)

Localization

# vim /etc/locale.gen

uncomment en_US.UTF-8 UTF-8 and en_US ISO-8859-2

generate localization files

# locale-gen

Setting the time and date using OpenNTP

dopnit

Setting the time and date manually

complete

Changing the root password

After the first start RPI is native root password to root. It is therefore necessary to change it. Executed after power command passwd

# passwd root

Adding another user

Using adduser to add the user.

# adduser

Sudo

Start visudo

# sudo visudo

add the line "USER ALL = (ALL) ALL" below the line root ALL = (ALL) ALL

Installing programs and environment

Below is a brief overview of the basic packages and procedures that are initially desolation RPI could come in handy.

Search

To search for files and folders on the disc serves mlocate.

# pacman-S mlocate

after installation, you must restore the database

# updatedb

Shell

For work I recommend zsh.

# pacman-S zsh

run

$ chsh

and set

/bin/zsh

Graphical environment

You need to install X server xorg:

# pacman -S xorg-server xorg-xinit xorg-server-utils xinit xterm xorg-xinit

Mesa

# pacman -S mesa

Video card drivers xf-video

# pacman-SYF xf86-video-fbdev

Which is connected with gamin and dbus

# pacman-S dbus gamin

Graphical environment LXDE:

# pacman -S lxde

further into the set ~/.xinitrc add the following line:

$ vim ~ /.Xinitrc (if they do not root)

insert

exec ck-launch-session dbus-launch startlxde

Running LXDE environment

$ startx
