Note: '''Work In Progress'''
If you don't want to follow these instructions and would prefer to download an image you can do so by downloading the image from [[Asterisk for Raspberry Pi Image]].


These instructions work for the Raberry Pi B-512 version with 512 MB RAM and not the 256MB version. You can follow these instruction for the 256MB version but you will have to skip the fax 2 email section.
The following instructions are based on Arch Linux ARM (archlinux-hf-2013-07-22.img.zip)


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]].
= Write Image to SD Card =
Using [http://launchpad.net/win32-image-writer/+download Win32DiskImager] and the latest version of [http://www.raspberrypi.org/downloads Arch Linux ARM] from Raspberry Pi write the image to the SD card.


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

Latest revision as of 11:30, 12 March 2014

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

The following instructions are based on Arch Linux ARM (archlinux-hf-2013-07-22.img.zip)

Write Image to SD Card

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

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

Update OS

pacman-key --init
pacman -Syu --noconfirm
reboot

Utilities

Install utilities to help with setup/administration 

pacman -S --noconfirm vim mlocate zip unzip

vi to vim

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

Create ll alias

vi /root/.profile

Add the following line 

alias ll="ls -la --color --group-directories-first --time-style=\"+%Y-%m-%d %H:%M\""

Time Synchronisation

cp -f /usr/share/zoneinfo/Australia/Brisbane /etc/localtime

Set IP Address

vi /boot/cmdline.txt

Add the following text. Make sure there is no carriage return at the end of the file and that everything is located on one line 

ip=192.168.1.11::192.168.1.254:255.255.255.0:rpi:eth0:off

Set DNS Servers, DNS suffix and DNS search. 

vi /etc/resolv.conf

add the lines 

domain mydomain.com
search mydomain.com
nameserver 192.168.1.254

After reboot check network settings 

ip addr show dev eth0

other useful commands 

ip addr add 192.168.17.250/24 dev eth0
ip route add 192.168.0.0/16 via 192.168.25.253 dev eth0


ip addr delete 192.168.17.250/24 dev eth0
ip route delete 192.168.0.0/16 via 192.168.25.253 dev eth0

Expand Partition

Now that the device has booted log on and change the default partition from 2 GB to the maximum partition 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 create a swap file to allow application 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 512M /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

add the line to the file 

/swapfile none swap defaults 0 0

Enable Sound Card

vi /etc/rc.conf

add the line 

MODULES=(snd-bcm2835)

pacman -S --noconfirm alsa-utils

Test with 

aplay /usr/share/sounds/alsa/Front_Left.wav && aplay /usr/share/sounds/alsa/Front_Center.wav && aplay /usr/share/sounds/alsa/Front_Right.wav

Regional settings

Enable AU or country specific entries. 

vi /etc/locale.gen

vi /etc/rc.conf
locale-gen

Hostname

vi /etc/hostname

Asterisk Packages

Asterisk uses initscripts to start, stop and manage the asterisk service. This causes a conflict with network and ntpdate. We need to install initscripts but remove the networking and clock functions. 

pacman -S --noconfirm initscripts 

vi /etc/rc.conf

Remove ntpdate, networking and sshd from DEAMONS=()

Install prerequisites for Asterisk. 

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

Secure mysql

/usr/bin/mysql_secure_installation

Install Asterisk

Download and install Asterisk. You can refer to Asterisk Install if required, but only Asterisk is required.


Set Asterisk to Automatic

vi /etc/rc.conf

and add asterisk to DEAMONS

logrotate

/etc/logrotate.d/asterisk

add the following lines to the file 

/var/log/asterisk/messages /var/log/asterisk/*log {
   missingok
   notifempty
   rotate 12
   weekly
   create 0640 root root
   postrotate
       /usr/sbin/asterisk -rx 'logger reload' > /dev/null 2> /dev/null
   endscript
}

logger

vi /etc/asterisk/logger.conf

change from: 

;dateformat=%F %T

to 

dateformat=%F %T %Z

Sendmail

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

vi /etc/ssmtp/ssmtp.conf

and add the lines 

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

Edit aliases if required 

vi /etc/ssmtp/revaliases

Install Apache

pacman -S --noconfirm 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

Locate date.timezone and change accordingly. 

date.timezone = Australia/Brisbane

For a list of time zones 

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/

CDR

Refer to the Call Detail Records page which will allow Asterisk to write the CDR records to the database.

aCDR

aCDR is a web appliction that allows you to search throught your CDR records. View the aCDR page on installation.

Backup Script

Refer to Asterisk Backup Shell Script for the script itself. 

pacman -S --noconfirm smbclient

perl

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

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