how to install ntopng on centos

Install NTOP NG 1.0.1 on CentOS 6.4
Let’s install the latest NTOP, 1.0.1, on CentOS 6.4 by using YUM to make it easy.

Note: NTOP must be installed on a 64-bit operating system.

1. Create a repository for NTOP.
     vi /etc/yum.repos.d/ntop.repo
        [ntop]
        name=ntop packages
        baseurl=http://rpm.ntop.org/$releasever/$basearch/
        enabled=1
        gpgkey=http://www.nmon.net/centos/RPM-GPG-KEY-deri
 
2. Add the EPEL repository, if it doesn’t already exist
    rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

3.  Install the packages.
   yum clean all
   yum update
   yum install pfring n2disk nProbe ntopng

4.Set NTOP to start on boot.
    chkconfig ntopng on
    chkconfig redis on

5. Download the GeoLite databases for GeoIP.
    cd /usr/local/share/ntopng/httpdocs/geoip
    wget http://download.maxmind.com/download/geoip/database/asnum/GeoIPASNum.dat.gz
    gunzip GeoIPASNum.dat.gz
    wget http://download.maxmind.com/download/geoip/database/asnum/GeoIPASNumv6.dat.gz
     gunzip GeoIPASNumv6.dat.gz
    wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
    gunzip GeoLiteCity.dat.gz
    wget http://geolite.maxmind.com/download/geoip/database/GeoLiteCityv6-beta/GeoLiteCityv6.dat.gz
    gunzip GeoLiteCityv6.dat.gz

6.Create the NTOP configuration directory and files.
    mkdir /etc/ntopng
    touch /etc/ntopng/ntopng.start
    touch /etc/ntopng/ntopng.conf
    vi /etc/ntopng/ntopng.start
            --local-networks 「your subnet here」
            --interface 1
    vi /etc/ntopng/ntopng.conf
            -G=/var/run/ntopng.pid
7.Start the services.
    service redis start
    service ntopng start (Note: At the time of writing 「service ntopng stop」 did not work.)

8.Browse to the NTOP server address.
