Introduction
Cacti is a web-based utility that graphs interesting statistics of unlimited network hosts using SNMP.
This is a copy more or less of http://forum.qnap.com/viewtopic.php?f=32&t=21218
Preparation
Log into your QNAP with SSH.
# ipkg install rrdtool # ipkg install net-snmp # ipkg install php-mysql # ipkg install mysql # ipkg install perl # ipkg install patch
Grab the latest Cacti
# wget http://www.cacti.net/downloads/cacti-0.8.7e.tar.gz
Extract the downloaded file and put the extracted files in a new directory:
# tar -zxvf cacti-0.8.7e.tar.gz # cd /share/MD0_DATA/.qpkg/ # mkdir cacti # mv /root/cacti-0.8.7e/* cacti
Do Some Patching
# wget http://www.cacti.net/downloads/patches/0.8.7e/cli_add_graph.patch # wget http://www.cacti.net/downloads/patches/0.8.7e/cross_site_fix.patch # cd cacti # patch -p1 -N < cli_add_graph.patch
(in my case i got on the first patch a error (1 out of 1 hunk ignored -- saving rejects to file cli/add_graphs.rej))
Add Cactigroup and a Cacti User
The groupname will be cactigrp and the user will be cacti
# addgroup cactigrp # adduser -h /share/MD0_DATA/.qpkg/cacti -s /bin/false -G cactigrp cacti
Configure MySQL server
(to check use phpMyAdmin) password would be sqladmin with
# mysqladmin -u root -p status
You will find out if it is already running
if not
# /opt/bin/mysqld_safe & # mysql -u root -p sqladmin<br>create the new Database # mysqladmin -u root -p create CACTIDB
add the fresh datas
mysql -u root -p CACTIDB < /share/MD0_DATA/.qpkg/cacti/cacti.sql
