8.Install Cacti
Run these commands as root

mysql --user=root --password=rootpw cactidb < database_defaut =" “cactidb”;" database_hostname =" “localhost”;" database_username =" “cactiuser”;" database_password =" “cactipw”;"> /dev/null 2>&1

NOTE*** DO NOT RUN THE ABOVE COMMAND. LET THE CRONTAB FILE RUN IT.
If you run the above command as root there will be several files created under ...../rra and ..../log that will
now be owned by the user ROOT and your graphs will NOT populate correctly. So the moral is... JUST
TYPE IN WHAT YOU SEE ABOVE AND SAVE THE FILES. DONT RUN THEM.

Add these script to /etc/snmp/snmp.conf

#define RO community
rocommunity public

#First, map the community name "public" into a "security name"

# sec.name source community
com2sec notConfigUser default public

####
#second. map the security name into a group name:

# groupName securitymodel securityName
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser

####
#Third, create a view for us to let the group have rights to:
# name incl/excl subtree mask(optional)
view systemview included system
access notConfigGroup "" any noauth exact systemview none none

Finalize Setup
You are now ready to finalize the setup process for cacti.
To do this you will need to point your browser to
the IP address of the cacti system like so:
http://localhost/cacti
or
http://remoteIP/cacti
1. Click Next
2. Default (New Install) -> Click Next
3. Two errors locating php and rrdtool to Fix them replace what they have with:
RRDTOOL = /usr/local/rrdtool/bin/rrdtool
PHP = /www/php/bin/php
4. Click Finish
5. Login admin/admin
6. Change Password for user admin
7. Click Save
That's it! Your done. Congratulations on your new install. You can now start playing with the cacti utility
it's self. I highly recommend going to the message boards to find add-ons and helpful hints when trying to
do any advanced things in cacti. This is a highly versatile utility and is really only limited to your
imagination.
