Step by step

Packages installation

yum -y install httpd wireshark php php-gd php-mysql php-mbstring mtr php-process mysql-server librsvg2
chkconfig --add httpd
chkconfig httpd on
/etc/init.d/httpd start
chkconfig --add mysqld
chkconfig mysqld on
/etc/init.d/mysqld start

Sniffer installation

cd /usr/src/
wget --content-disposition http://www.voipmonitor.org/current-stable-sniffer-static-32bit.tar.gz
tar xzf voipmonitor*.tar.gz
cd voipmonitor*
./install-script.sh
mkdir /var/spool/voipmonitor/
chown apache /var/spool/voipmonitor/

Create database

mysqladmin create voipmonitor

Installing WEB GUI

cd /var/www/html
wget "http://www.voipmonitor.org/download-gui?version=latest&major=5&allowed" -O w.tar.gz
tar xzf w.tar.gz
mv voipmonitor-gui*/* ./
rm -f index.html
chown -R apache /var/www/html

Installing wkhtmltopdf binaries needed for GUI charts and reprots

wget http://sourceforge.net/projects/voipmonitor/files/wkhtml/0.10.0_rc2/wkhtmltoimage-x86_64 -O "/var/www/html/bin/wkhtmltoimage-x86_64"
chmod +x "/var/www/html/bin/wkhtmltoimage-x86_64"
wget http://sourceforge.net/projects/voipmonitor/files/wkhtml/0.10.0_rc2/wkhtmltopdf-x86_64 -O "/var/www/html/bin/wkhtmltopdf-x86_64"
chmod +x "/var/www/html/bin/wkhtmltopdf-x86_64"

Installing IonCUBE extension for PHP which is neccessery for running voipmonitor GUI php scripts

wget http://voipmonitor.org/ioncube/x86_64/ioncube_loader_lin_5.3.so -O /usr/lib64/php/modules/ioncube_loader_lin_5.3.so
echo "zend_extension = /usr/lib64/php/modules/ioncube_loader_lin_5.3.so" > /etc/php.d/ioncube.ini

Disabling SELINUX which blocks IonCUBE and access to /var/spool/voipmonitor for PHP process preventing to GUI work as expected. Turning off SELINUX is the simplest solution but feel free to configure otherwise

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
setenforce 0
/etc/init.d/httpd restart
