Mini-Tutorial: Fresh Install of ntopng on Centos 7

Posted · Add Comment

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 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
      

Enjoy!
