Instaling ntopng on CentOS

Mini-Tutorial: Fresh Install of ntopng on Centos

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
    

• 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 running

    $ 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
