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
pacman -S ntp
ntpdate ntp.bri.connect.com.au

vi /etc/rc.conf
hwclock (remove)
ntpdate (add)


= Hostname =
<pre>
vi /etc/hostname
vi /etc/hosts

vi /etc/dhcpcd.conf
           add line: nohook resolv.conf
        remove line: nohook lookup-hostname

Network

vi /etc/conf.d/network
<pre>
add the lines
<pre>
interface=eth0
address=192.168.1.1
netmask=255.255.255.0
broadcast=192.168.0.255
gateway=192.168.1.254
<pre>

<pre>
vi /etc/systemd/system/network.service

add the lines

[Unit]
Description=Network Connectivity
Wants=network.target
Before=network.target

[Service]
Type=oneshot
RemainAfterExit=yes
EnvironmentFile=/etc/conf.d/network
ExecStart=/sbin/ip link set dev ${interface} up
ExecStart=/sbin/ip addr add ${address}/${netmask} broadcast ${broadcast} dev ${interface}
ExecStart=/sbin/ip route add default via ${gateway}
ExecStop=/sbin/ip addr flush dev ${interface}
ExecStop=/sbin/ip link set dev ${interface} down

[Install]
WantedBy=multi-user.target

systemctl disable dhcpcd@eth0.service
systemctl enable network.service

reboot

vi /etc/resolv.conf

add the lines

domain mydomain.com
search mydomain.com
nameserver 192.168.1.254

Asterisk Pacgages

pacman -S gcc make hgsvn libxml2 libnewt sqlite subversion mysql spandsp speex
systemctl enable mysqld.service
systemctl start mysqld.service
<pre>

== Secure mysql ==
<pre>
/usr/bin/mysql_secure_installation

Free Memory

So Asterisk will compile we need to free as amny applictions as possible from memory

systemctl stop ntpd.service
systemctl stop mysqld.service

Install Asterisk

Download and install Asterisk. you can refer to [Asterik Install] if required, but only Asterisk is required.

Set Asterisk to Automatic

vi /etc/rc.conf

and add asterisk to DEAMONS

Sendmail

pacman -R heirloom-mailx
rm /etc/mail.rc.pacsave
pacman -S ssmtp

vi /etc/ssmtp/ssmtp.conf

and add the lines

mailhub=192.168.13.3
hostname=rpi.klaverstyn.com
FromLineOverride=yes

Install Apache

pacman -S apache php-apache php php-gd

vi /etc/httpd/conf/httpd.conf

and modify the following

AllowOverride All
DirectoryIndex index.php index.html index.htm index.html.var

systemctl enable httpd.service

Configure php

vi /etc/php/php.ini

uncomment

extension=mysqli.so
extension=mysql.so

vi /etc/httpd/conf/httpd.conf

add the following lines in thier respective sections

LoadModule php5_module modules/libphp5.so
Include conf/extra/php5_module.conf
AddHandler application/x-httpd-php .php

uncomment the following lines

TypesConfig conf/mime.types
MIMEMagicFile conf/magic

vi /etc/httpd/conf/mime.types

add the following line

application/x-httpd-php5		php php5

systemctl start httpd.service

Note': The web root is /srv/http/

Backup Script

Refer to [Astetrisk Backup] for the script itself.

pacman -S smbclient

perl

NOTE: to install the perl module requires more RAM that what is avaiazble on the 256MM model of the rPi. Make sure you have a swap file otherwise this section will fail.

pacman -S perl cpan libyaml perl-yaml libyaml perl-libwww sox mpg123
