Original how to is posted at: http://forums.linuxwebadmin.info/index.php/topic,153.0.html

Introduction:

Cacti is a complete frontend to RRDTool, it stores all of the necessary information to create graphs and populate them with data in a MySQL database. The frontend is completely PHP driven. Along with being able to maintain Graphs, Data Sources, and Round Robin Archives in a database, cacti handles the data gathering. There is also SNMP support for those used to creating traffic graphs with MRTG.

Cacti requirement:

MySQL
PHP
RRDTool
net-snmp
php-snmp
Apache (compiled with php support)


MySQL configuration for cacti:

Code:

[root:~]# mysql -uroot -p
Enter password: 
mysql> create database cactidb;
mysql> grant all on cactidb.* to root;
mysql> grant all on cactidb.* to root@localhost;
mysql> grant all on cactidb.* to cactiuser;
mysql> grant all on cactidb.* to cactiuser@localhost;
mysql> set password for cactiuser@localhost=password('cactipw');
mysql> flush privileges;
mysql> exit
[root:~]#

RRDTool Installation:

Code:

[root:~]# cd /usr/local/src/
[root:~]# wget http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/pub/rrdtool.tar.gz
[root:~]# tar -zxf rrdtool.tar.gz
[root:~]# cd rrdtool*
[root:~]# ./configure
[root:~]# make
[root:~]# make install
[root:~]# make site-perl-install
[root:~]# cd ..
[root:~]# rm -fr rrdtool*
[root:~]# 

Download and setup cacti:

Code:

[root:~]# group-add cacti
[root:~]# useradd -g cacti cactiuser

Code:

[root:~]# tar -zxvf cacti*
[root:~]# mv cacti-0.8.xx /home/cactiuser/cacti
[root:~]# cd /home/cactiuser/cacti
[root:~]# mysql --user=root --password=rootpw cactidb < cacti.sql
[root:~]# chown -R cactiuser rra/ log/

Make the proper changes for database and database password:

[root:~]# vi /include/config.php

Code:

$database_defaut = “cactidb”;
$database_hostname = “localhost”;
$database_username = “cactiuser”;
$database_password = “cactipw”

Add this cron in /etc/crontab

*/5 * * * * cactiuser php /home/cactiuser/cacti/poller.php > /dev/null 2>&1

Add an alias or virtual host in your apache configuration file:

Alias /cacti/ "/home/cactiuser/cacti/"

Save and restart the apache and mysql service.
