Centreon: NTOP

How to install NTOP in Centreon, I started it but couldn’t finish it because of the incompatibility of NTOP module with the newer Centreon versions. Read more:

yum install -y libtool
yum install libpcap libpcap-devel gdbm gdbm-devel -y
yum install rrdtool-devel -y
yum install geoipp geoip-devel -y

./autogen.sh –prefix=/usr/local –with-rrd-home=/usr/bin
make
make install

************************************************************
************************************************************

  WARNING: This install created a directory for the ntop
           files and databases:

             //usr/local/share/ntop

           This directory MUST be owned by the user
           which you are going to use to run ntop.

           The command you must issue is something like:

           chown -R ntop.ntop //usr/local/share/ntop
     or    chown -R ntop:users //usr/local/share/ntop

           man chown to check the syntax for YOUR system

************************************************************
************************************************************

/usr/local/bin/ntop -u ntop -A

chown -R ntop:ntop /usr/local/share/ntop/
chown -R  ntop:ntop /usr/local/var/ntop/
chown -R  ntop:ntop /usr/local/etc/ntop/

Install dot (graphviz) to create traffic maps:

wget http://www.graphviz.org/graphviz-rhel.repo
mv graphviz-rhel.repo /etc/yum.repos.d/
yum list available ‘graphviz*’
yum install ‘graphviz*’
which dot
ln -s /usr/bin/dot /usr/local/bin/dot

ON ANOTHER SERVER cause install subversion comes with a lot of dependencies
yum install subversion
svn co http://svn.modules.centreon.com/centreon-ntop/trunk/www/modules/
cd modules
yum install dos2unix
find . -type f -exec dos2unix {} \;
scp -r ntop root@10.0.2.18:/usr/local/centreon/www/modules/
