Preface

The following instructions were written for CentOS 5.6. http://mirror.centos.org/centos/5/isos/ After installing CentOS follow the instructions below.

Dependencies

Install the following dependencies

yum -y install subversion autoconf automake libtool gcc-c++ git-core ncurses-devel make expat-devel bison zlib zlib-devel ghostscript gettext-devel
yum -y install nano unixODBC-devel openssl-devel gnutls-devel libogg-devel libvorbis-devel curl-devel libtiff-devel libjpeg-devel python-devel expat-devel zlib zlib-devel bzip2

Repositories

CentOS does not yet ship a recent enough version of PHP in order to use PHP FPM (fast cgi), so we suggest you use the RPMs provided in the Webtatic repository. Also, this allows GIT to be installed via YUM. To do so:

rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm 
rpm -Uvh http://repo.webtatic.com/yum/centos/5/latest.rpm

GIT Install

Since we added the epel repo, GIT can be installed via YUM

yum -y install git

FreeSWITCH Install

Then use the following

cd /usr/src/
git clone git://git.freeswitch.org/freeswitch.git
cd /usr/src/freeswitch
./bootstrap.sh

Edit modules.conf to enable or disable desired modules. To enable a few extra features you may want to go ahead and edit modules.conf. Remove the # in front of the lines with these modules:

mod_rtmp
mod_directory
mod_callcenter
mod_tts_commandline
mod_dingaling
mod_flite
mod_shout
mod_pocketshpinx
mod_cidlookup

Complete the FreeSWITCH compile.

./configure
make install
make samples

8 kHz Standard Audio

make sounds-install
make moh-install

16 kHz High Definition Audio

make hd-moh-install
make hd-sounds-install

32 kHz Ultra High Definition Audio

make uhd-moh-install
make uhd-sounds-install

48 kHz CD Quality Audio

make cd-sounds-install
make cd-moh-install

To upgrade FreeSWITCH in the future do the following:

cd /usr/src/freeswitch
make current

FreeSWITCH Auto Start

Copy the sample-init-file to /etc/init.d/

 cp build/freeswitch.init.redhat /etc/init.d/freeswitch

Replace /opt/freeswitch with /usr/local/freeswitch in the /etc/init.d/freeswitch

sed -i 's/\/opt\/freeswitch/\/usr\/local\/freeswitch/g' /etc/init.d/freeswitch

Set the permissions and add it to run on startup

chmod 765 /etc/init.d/freeswitch
/sbin/chkconfig --add freeswitch
/sbin/chkconfig --level 5 freeswitch on
/sbin/chkconfig --list freeswitch

FreeSWITCH conf

Disable the following files but leave them for examples

cd /usr/local/freeswitch/conf/dialplan/default
mv 00_ladspa.xml 00_ladspa.noload
mv 00_pizza_demo.xml 00_pizza_demo.noload
mv 01_Talking_Clock.xml 01_Talking_Clock.noload

SELinux

Can create problems for file access and running services. The following link describes how to disable SELinux.

http://www.crypt.gen.nz/selinux/disable_selinux.html

Database

SQLite

Is installed with PHP

PostgreSQL

Postgres 8.4 or higher is required. The following instructions install version 9.0 Replace the custom-username and custom-password with the account information.

http://wiki.postgresql.org/wiki/YUM_Installation (additional information)

Locate and edit your distributions .repo file, located: [base] and [updates] sections

nano /etc/yum.repos.d/CentOS-Base.repo

To the section(s) identified above, you need to append a line:

exclude=postgresql*

Download and install PGDG RPM file

wget  http://yum.postgresql.org/9.0/redhat/rhel-5-i386/pgdg-centos90-9.0-5.noarch.rpm
rpm -ivh pgdg-centos-9.0-5.noarch.rpm
yum install postgresql90-server
service postgresql-9.0 initdb
/sbin/chkconfig postgresql-9.0 on
service postgresql-9.0 start
su postgres
psql
CREATE ROLE custom-username WITH SUPERUSER LOGIN PASSWORD 'custom-password';
\q
exit
sed -i 's/ident/md5/g' /var/lib/pgsql/9.0/data/pg_hba.conf
service postgresql-9.0 restart

MySQL

Check to see if MySQL is installed

yum --enablerepo=webtatic list mysql55 mysql55-server

If it is installed then update it to a newer version

yum --enablerepo=webtatic upgrade mysql55 mysql55-server

If it is not installed then add it

yum –-enablerepo=webtatic install mysql55 mysql55-server
/sbin/chkconfig mysqld on
service mysqld start

Set the root password

mysqladmin -u root password new_password_here
mysqladmin -h 127.0.0.1 -u root password new_password_here

PHP

yum --enablerepo=webtatic install php php-common php-pdo php-soap php-xml php-xmlrpc 
yum --enablerepo=webtatic upgrade php php-common php-pdo

For PostgreSQL add

yum --enablerepo=webtatic install php-pgsql

For MySQL then add

yum --enablerepo=webtatic install php-mysql mysql-connector-odbc

Install PHP Fast CGI

yum --enablerepo=webtatic install php-fpm
/sbin/chkconfig php-fpm on

Web Server

There are multiple choices for a web server to use. These instructions focus on nginx because it takes very little server resources and scales well.

NGINX (pronounced: engine x)

yum --enablerepo=webtatic install nginx
/sbin/chkconfig nginx on

Add the following directories.

mkdir /etc/nginx/sites-available
mkdir /etc/nginx/sites-enabled

Remove the original config and add a more flexible one. Don't try to paste these in all at once because the "rm" and the wgets will make you miss something following.

cd /etc/nginx
rm nginx.conf
wget http://www.fusionpbx.com/downloads/centos/nginx/nginx.conf
cd /etc/nginx/sites-available
wget http://www.fusionpbx.com/downloads/centos/nginx/fusionpbx.conf
ln /etc/nginx/sites-available/fusionpbx.conf /etc/nginx/sites-enabled/fusionpbx.conf

OpenSSL

Make sure the /etc/ssl directory exists

mkdir -p /etc/ssl

Change the directory

cd /etc/ssl

Generate a private key:

openssl genrsa -des3 -passout pass:fusionpbx_cert_password -out fusionpbx.ssl.key 1024

Remove password from private key:

openssl rsa -in fusionpbx.ssl.key -passin pass:fusionpbx_cert_password -out fusionpbx.ssl.key.nopass

Create a CSR (certificate signing request):

openssl req -new -key fusionpbx.ssl.key.nopass -out fusionpbx.ssl.csr -subj "/CN=fusionpbx/OU=Project/O=FusionPBX/L=Boise/C=US"

Generate self-signed cert:

openssl x509 -req -days 3650 -in fusionpbx.ssl.csr -signkey fusionpbx.ssl.key.nopass -out fusionpbx.ssl.crt

FusionPBX

Download FusionPBX source and add it to the web server directory.

cd /var/www
svn checkout http://fusionpbx.googlecode.com/svn/trunk/fusionpbx /var/www/fusionpbx

If you get an error: 'svn: command not found.' Then add subversion. Then run the svn checkout again.

yum install subversion

Permissions

There are multiple ways to handle permissions. FreeSWITCH creates some file on demand such as voicemail and does not give the necessary group permissions because of that the following method is currently recommended. This method adds the www-data user, changes ownership of the files to use www-data and then make the php-fpm and freeswitch services run as www-data.

/usr/sbin/adduser www-data
chown -R www-data:www-data /usr/local/freeswitch
chown -R www-data:www-data /var/www/fusionpbx
sed -i 's/user = apache/user = www-data/g' /etc/php-fpm.d/www.conf
sed -i 's/group = apache/group = www-data/g' /etc/php-fpm.d/www.conf
sed -i 's/${FS_USER-freeswitch}/${FS_USER-www-data}/g' /etc/init.d/freeswitch
chown -R www-data:www-data -R /var/lib/php/session

Network Time Protocol

If NTP is not installed then install it.

yum install ntp
chkconfig ntpd on
ntpdate pool.ntp.org
service ntpd start

If NTP is running then do the following:

service ntpd stop
ntpdate pool.ntp.org
service ntpd start

Fail2ban

Brute force attacks are common. If the SIP and RTP ports are exposed to the Internet then it is important to install and configure Fail2ban. Fail2ban can be configured to analyze the FreeSWITCH logs. When attacker are identified it blocks the offenders.

yum install fail2ban
cd /etc/init.d
/sbin/chkconfig fail2ban on

The configurations directory is

/etc/fail2ban

For more info go to Fail2Ban

Start the remaining services

Start php-fpm (Without doing so will result in ERR 502 BAD GATEWAY)

service php-fpm start

Start FreeSWITCH

service freeswitch start

Start nginx (Web Server)

service nginx start

Browser

To complete install go to the ip address or domain of the server in your web browser. You can use http or https and follow the instructions.

Login

After completing the install the default login information is whatever you set during setup after your initial connection to the web page.

Defaults used to be:

user: superadmin

pass: fusionpbx

System setup now makes you choose
