          tar -xvf FlowViewer_4.6.tar
          yum install httpd
          mv FlowViewer_4.6 /var/www/cgi-bin/flowviewer

FlowViewer Configuration:

Edit the FlowViewer_Configuration.pm file and update the path.. make sure the Paths are Valid if the Floders are not exist.. Please create it manually.
Copy the config file to the correct directory.
          cp /var/www/cgi-bin/flowviewer/tools/flow-capture-table.conf /etc/flow-capture-table.conf

Edit the flow-capture-table.conf file and update the router and port number details.
Copy the flowcapture init script to the init.d directory.
           cp /var/www/cgi-bin/flowviewer/tools/flowcapture_restart /etc/init.d/flowcapture

Start the flowcapture..
            /etc/init.d/flowcapture start

Point your browser to http://<YOUR -SERVER_IP>/cgi-bin/flowviewer/FV.cgi

P.S: flowgrapher Setup is not updated in the installtion. I will add it in future..

How to Install Cacti on Centos

This procedure explains the Cacti installation on Centos Server using Yum.


Step1: Install the dependencies.

[:vishnu:root@sandbox ~]# yum install mysql-server mysql php-mysql php-pear php-common php-gd php-devel php php-mbstring php-cli php-snmp php-pear-Net-SMTP php-mysql httpd

[:vishnu:root@sandbox ~]# yum install net-snmp-utils php-snmp net-snmp-libs


Step2: start mysqld and configure it

[:vishnu:root@sandbox ~]# service mysqld status
mysqld is stopped
[:vishnu:root@sandbox ~]# service mysqld start

Initializing MySQL database: Installing MySQL system tables...
OK
<<Output Suppressed>>
[ OK ]
Starting MySQL: [ OK ]
[:vishnu:root@sandbox ~]#
[:vishnu:root@sandbox ~]# /usr/bin/mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In <Output Omitted>
Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.
Set root password? [Y/n] Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] Y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] Y
... Success!
By default, MySQL comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] Y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] Y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MySQL
installation should now be secure.
Thanks for using MySQL!

Step3: Install Cacti

[:vishnu:root@sandbox ~]# yum install net-snmp-utils php-snmp net-snmp-libs
[:vishnu:root@sandbox ~]# yum install cacti

If cacti package is not available. Add the below repo to your machine and run the command again.
#vim /etc/yum.repos.d/dag.repo:
[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
gpgkey=http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
enabled=1

Step4: Install Spine

Download the latest file from the cacti.net

tar xvzf cacti-spine-*.tar.gz
cd cacti-spine-*
./configure
make
sudo make install
Spine Path /usr/local/spine/bin/spine ​


Step5: Update the correct database details in /var/www/cacti/include/config.php

$database_type = "mysql";
$database_default = "cacti";
$database_hostname = "localhost";
$database_username = "cacti";
$database_password = "cacti";
$database_port = "3306";
$database_ssl = false;


Step6: Spine config: update the below variables in spine.conf file

###Copy the config file first
cp /usr/local/spine/etc/spine.conf.dist /usr/local/spine/etc/spine.conf

DB_Host localhost
DB_Database cacti
DB_User cacti
DB_Pass cacti
DB_Port 3306
DB_PreG 0

step:6 create a database called cacti in mysql
#mysql -u root -p
#mysqladmin --user=root create cacti
#mysql --user=root mysql
mysql# GRANT ALL ON cacti.* TO cactiuser@localhost IDENTIFIED BY 'somepassword';
mysql# flush privileges;​

Step:7 Correct the Folder permission:
cd /var/www/cacti/
chown -R cacti rra/ log/

Step:8 Edit the cacti.conf file and add the "allow from all" in it.

#vim /etc/httpd/conf.d/cacti.conf
Alias /cacti/ /var/www/cacti/
<Directory /var/www/cacti/>
DirectoryIndex index.php
Options -Indexes
AllowOverride all
order deny,allow
deny from all
allow from all
AddType application/x-httpd-php .php
php_flag magic_quotes_gpc on
php_flag track_vars on
</Directory>

Step:9 reload httpd config file.
# service httpd reload


Step 10 point your browser to:
http://your-server/cacti

If you look at the above logs the rpm was stuck while doing the + groupadd -g 85 -r quaggavt command
When i try running the command separetly it was stuck in the same position.
hence i checked the /etc/nsswitch.conf file for any authentication issue.
and then i found that the /etc/nsswitch.conf has a ldap configuration and the ldap server was not reachable due to that the groupadd command was not working.
Removed the ldap configuration form the /etc/nsswitch.conf and i was able to install the quagga rpm successfully.
