Asterisk for Raspberry Pi on ArchLinux

If you don't want to follow these instuctions and would prefer to download an image you can do so by downloading the image from Asterisk for Rasberry Pi Image.

The following instructions are based on Arch Linux ARM (archlinux-hf-2012-09-18.zip)

Write Image to SD Card

Using Win32DiskImager and the latest version of Arch Linux ARM from Rasberry Pi write the image to the SD card.

Once the image is written insert the Sd card into the Rasberry Pi and boot. The device will get an IP address from DHCP.

Expand Parition

Now that the device has booted log on and change the default partiion from 2 GB to the maximum partiion of your SD card.

fdisk /dev/mmcblk0
d (delete)
2 (partition 2)
n (new)
p (primary partition)
2 (partition 2 as previously deleted)
enter (accept default start sector)
enter (accept default end sector)
w (write changes)

reboot

Once the rPi has rebooted

resize2fs /dev/mmcblk0p2
reboot

Swap File

As the rPi has limited RAM, either 256 or 512 depending on your version we'll creat a swap file to allow appliction to use higher memory if required.

I would recommend allocating the size of the swap file to be that equal to the RAM size.

fallocate -l 256M /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile

The swap file is now active. We now need to ensure that it is used at boot.

vi /etc/fstab
<pre>
add the line to the file
<pre>
/swapfile none swap defaults 0 0

Update OS

pacman -Syu
reboot

Utilities

Install utilities to help with setup/administration

  # pacman -S initscripts vim mlocate zip unzip

vi to vim

pacman -R vi
ln -s /usr/bin/vim /usr/bin/vi

Create ll alias

vi /root/.profile
<pre>

add the line
<pre>
alias ll="ls -la"

= Enable Sound Card =

vi /etc/rc.conf
<pre>

add the line

<pre>
MODULES=(snd-bcm2835)

Regional settings

vi /etc/locale.gen (enable all AU and US, 4 lines)
vi /etc/rc.conf
locale-gen

Time Synchronisation

cp /usr/share/zoneinfo/Australia/Brisbane /etc/localtime
pacman -R openntpd
