Purpose
The purpose of this page is to give you instructions on how to setup a PBX system using
OpenBSD∞ v4.6,
Asterisk∞ v1.4, and
FreePBX∞ v2.6.
Goal
To build a server that has SIP trunking back to the telco and allows the use of IP phones internally to your office/home.
Hardware
CPU: Intel
Core2 Duo CPU E8400 @ 3.00GHz
RAM: 2GB DDR2 SDRAM ECC PC2-6400CL5
Raid card: Areca, ARC-1210 (4-port SATA II) F/W 1.47
Hard drives: A RAID 1 setup with a set of 1TB Seagate SATA II HD's with a signal hot spare
Software
OpenBSD∞ operating system. I will be using 4.6 Stable
Asterisk∞ PBX software. I will be using the package version available to
OpenBSD 4.6 which is v1.4.25.1p0.
FreePBX∞ GUI configuration tool for Asterisk PBX software. This I will be v2.6.0final
Step 1 - Assemble Hardware
Done!
Step 2 - Install OS
Check out
this∞ page for detailed instructions on how to install the OS
The following is the partition layout that I chose.
# disklabel -h sd0
# size offset fstype [fsize bsize cpg]
a: 2.0G 480 4.2BSD 2048 16384 1 # /
b: 6.0G 4210560 swap
c: 931.3G 0 unused
d: 6.0G 16809600 4.2BSD 2048 16384 1 # /tmp/
e: 8.0G 29408640 4.2BSD 2048 16384 1 # /var
f: 2.0G 46218240 4.2BSD 2048 16384 1 # /var/log
g: 16.0G 50428800 4.2BSD 2048 16384 1 # /usr
h: 8.0G 84015360 4.2BSD 2048 16384 1 # /home
i: 800.0G 100824960 4.2BSD 2048 16384 1 # /asterisk
Edit your profile file found here: /root/.profile Add the following lines to the end of it.
# vi /root/.profile
# Set package path for package installation purposes
PKG_PATH=ftp://mirror.planetunix.net/pub/OpenBSD/4.6/packages/i386
export PKG_PATH
# OpenBSD emacs type editor
alias mg="mg -n"
Step 3 - Install additional packages
* I like to see what the package manager is doing when it installs packages. If you do not want to see the details take the -v off the following commands.
I like to use the utility wget so I install the package for wget
# pkg_add -vi wget
I like to have screen also
# pkg_add -vi screen-4.0.3p1
For all of the following packages you will need to be sure to complete the instructions for each related package that you install.
Install Asterisk
# pkg_add -vi asterisk-1.4.25.1p0
# pkg_add -vi asterisk-native-sounds
# pkg_add -vi asterisk-sounds
# pkg_add -vi asterisk-openbsd-moh
Install
MySQL Server
# pkg_add -vi mysql-server Install PHP extension w/PEAR
# pkg_add -vi php5-core
# pkg_add -vi php5-mysql
# pkg_add -vi pear
# pkg_add -vi pear-DB
You can do them all at once here
# pkg_add -iv asterisk-1.4.25.1p0 asterisk-native-sounds asterisk-sounds asterisk-openbsd-moh mysql-server php5-core php5-mysql pear pear-DB wget screen-4.0.3p1
After all this, you should end up with a package list something like the following
# pkg_info
asterisk-1.4.25.1p0 open source multi-protocol PBX and telephony toolkit
asterisk-native-sounds-1.2p0 'native' (better) sound files for Asterisk open source PBX
asterisk-sounds-1.2.1p3 extra sound files for Asterisk open source PBX
gettext-0.17p0 GNU gettext
gsm-1.0.13 u-law to gsm encoding audio converter and library
libiconv-1.13 character set conversion library
libxml-2.6.32p2 XML parsing library
mysql-client-5.0.83 multithreaded SQL database (client)
mysql-server-5.0.83 multithreaded SQL database (server)
p5-DBD-mysql-4.010 MySQL drivers for the Perl DBI
p5-DBI-1.607 unified perl interface for database access
p5-Net-Daemon-0.43 extension for portable daemons
p5-PlRPC-0.2018p0 module for writing rpc servers and clients
pear-1.7.2 base classes for common PHP tasks
pear-DB-1.7.6p0 database abstraction layer for PHP
pear-utils-1.7.2 utilities for managing pear extensions
php5-core-5.2.10 server-side HTML-embedded scripting language
php5-mysql-5.2.10 mysql database access extensions for php5
popt-1.7p0 getopt(3)-like library with a number of enhancements
screen-4.0.3p1 multi-screen window manager
wget-1.11.4 retrieve files from the web via HTTP, HTTPS and FTP
You will notice a few things in the list that were installed because they were dependencies
Their are now a few things that must be done to start the process of making this thing work right.
- You need to change the user and group that Apache runs as. The default user is www and www. You need to change this to _asterisk and _asterisk.
- In PHP you need to turn on the 'allow_url_fopen' setting in the php.ini file. (allow_url_fopen = On)
When changes are completed, restart Apache.
Step 3: Get the source file for freepbx
cd /usr/src/
wget http://mirror.freepbx.org/freepbx-2.6.0.tar.gz
tar zxpf freepbx-2.6.0.tar.gz
wget ftp://ftp.cmsws.com/patches/freepbx/freepbx-2.6.0-0.0.1.sh
ksh ./freepbx-2.6.0-0.0.1.sh
cd freepbx-2.6.0/
mysqladmin create asteriskcdrdb -p
mysql -u root -p asteriskcdrdb < SQL/cdr_mysql_table.sql
mysqladmin create asterisk -p
mysql -u root -p asterisk < SQL/newinstall.sql
mysql -u root -p
GRANT ALL PRIVILEGES ON asteriskcdrdb.* TO asteriskuser@localhost IDENTIFIED BY 'amp109';
GRANT ALL PRIVILEGES ON asterisk.* TO asteriskuser@localhost IDENTIFIED BY 'amp109';
FLUSH PRIVILEGES;
quit
./install_amp
POST INSTALL
After the install is complete. All you need to do is browse to the IP address of the machine that you used in the ./install_amp script.
Uninstall freepbx
rm /etc/amportal.conf
rm -r /var/lib/asterisk
rm -r /var/www/htdocs/amp/
rm /root/.asterisk_history
rm -r /var/www/htdocs/recordings/
mysqladmin drop asteriskcdrdb -p
mysqladmin drop asterisk -p
