Install ntopng on Centos 7

Oct 312014

This is how to compile ntopng in a fresh centos 7 x64 installation

For the impatient:

# yum install -y subversion autoconf automake make gcc

libpcap-devel libxml2-devel sqlite-devel libtool glib2-devel

 gcc-c++
$ svn co https://svn.ntop.org/svn/ntop/trunk/ntopng
$ ./autogen.sh 
$ ./configure
$ make
$ ./ntopng --help
ntopng x86_64 v.1.1.4 (r7865) - (C) 1998-14 ntop.org
<snip>

Step by step description
- Pull the source code from the ntop svn repository. To do this, you need first to install subversion using yum as follows
```
$ sudo yum -y install subversion
```
- Now change your directory to the one you want ntopng in and run
```
$ svn co https://svn.ntop.org/svn/ntop/trunk/ntopng
```
- Once the repository is downloaded, you should run the autogen.sh script
```
$ ./autogen.sh
```
- It will fail due to the lack of a autoconf packages. To step over this run
```
$ sudo yum install -y autoconf automake
```
- and re-run autogen.sh
```
$ ./autogen.sh
......
```
- Now autogen.sh completes successfully, then run ./configure, but it will fail due to the missing compiler
```
$ ./configure
.....
configure: error: no acceptable C compiler found in $PATH
```
- Install it using
```
$ sudo yum install -y gcc
```
  Next step is the missing libpcap development package
```
$ ./configure
......
```
- Please install libpcap(-dev) (http://tcpdump.org)
```
$ sudo yum install -y libpcap-devel
```
- Next mandatory package is libxml2-devel required by rrd compilation
```
$ ./configure
.....
```
- Please install libxml2(-devel) package (RRD prerequisite)
```
$ sudo yum install -y libxml2-devel
```
  and glib2-devel
```
$ ./configure
.....
```
- Please install libglib-2.0 (glib2-devel/libglib2.0-dev) package (RRD prerequisite)
```
$ sudo yum install -y glib2-devel
```
- now configure require another package
```
$ ./configure
SQLite 3.x missing (libsqlite3-dev): please install it and try again
```
- Installable runn
  ing
```
$ sudo yum install -y sqlite-devel
```
- Now configure works
```
$ ./configure
```
- You are now ready to compile typing /usr/bin/gmake
  But make will fail due the the missing c++ compiler
```
$ make
configure: error: Unable to find a working C++ compiler
$ sudo yum install gcc-c++
```
- After the last installed package, build will fail on json-c compilation with the following error
```
$ make
make: *** [third-party/json-c/.libs/libjson-c.a] Error 2
```
- To solve this, install libtool package using
```
$ sudo yum -y install libtool
```
- Then rerun make
```
$ make
```
- and you should have everything compiled successfully.
  Test is running:
```
$ ./ntopng --help
ntopng x86_64 v.1.1.4 (r7865) - (C) 1998-14 ntop.org
```

Enjoy!

IMPORTANT

This directory contains nightly builds (SVN code) of 64 bit binary packages for RedHat/CentOS (latest OS version). Please use rpm-stable.ntop.org for stable builds.

In order to use the repository you need to create a file named /etc/yum.repos.d/ntop.repo containing

# cat /etc/yum.repos.d/ntop.repo
[ntop]
name=ntop packages
baseurl=http://www.nmon.net/centos/$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=http://www.nmon.net/centos/RPM-GPG-KEY-deri
[ntop-noarch]
name=ntop packages
baseurl=http://www.nmon.net/centos/$releasever/noarch/
enabled=1
gpgcheck=1
gpgkey=http://www.nmon.net/centos/RPM-GPG-KEY-deri

and also install the /etc/yum.repos.d/epel.repo extra repositories

# cat /etc/yum.repos.d/epel.repo 
[epel]
name=Extra Packages for Enterprise Linux X - $basearch
mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=epel-X&arch=$basearch
failovermethod=priority
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-X

Note: replace X with 6 (for CentOS 6) or 7 (for CentOS 7) then do:

yum clean all
yum update
yum install pfring n2disk nprobe ntopng ntopng-data nbox

PF_RING is now packaged without ZC/DNA drivers. You can choose what family you want to install

ZC: yum install pfring-drivers-zc-dkms
DNA: yum install pfring-drivers-dna-dkms

Most software works without licenses. However some components do need a license. They include:

PF_RING DNA and libzero user-space libraries
nProbe (NetFlow/IPFIX probe)
n2disk (packet to disk application)

You can find more info on the ntop site, or acquire licenses on the ntop e-shop.

We remind you that all ntop products are available at no cost to universities and research.

NOTE

we periodically update the kernel package in order to build against a recent kernel. If you encounter issues while installing packages make sure you have first updated the linux kernel package.
