3. I modifed /etc/cron.d/cacti
old
*/5 * * * * wwwrun php /usr/share/cacti/poller.php > /dev/null 2>&1

to
*/5 * * * * wwwrun php5 /usr/share/cacti/poller.php > /dev/null 2>&1

(I have only php5 installed )

4. I modifed config.php with database settings. (in :/usr/share/cacti )

5. I copied :/usr/share/cacti to /srv/www/web4/web/cacti ( web 4 is on domain i would like access to cacti ... http://www.mydomain.com/cacti )

6. I runed install and selected those dropdowns for rrdtools, corrected php path etc..

7.I exec command:

Code:

php5 /srv/www/web4/web/cacti/poller.php

Received this error:

Code:

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/extensions/wddx.so' - /usr/lib/php5/extensions/wddx.so: undefined symbol: xml_utf8_encode in Unknown on line 0

8. I logged at cacti and changed password.

When i checked graphs i dont see them ... the graph picture are missing.
I also could not clear cacti log file ... so I chmod 777 cacti.log ( lol I)

Then i started to read:
http://www.howtoforge.com/cacti_ispconfig

I notice i did not do:
sudo chown -R www-data:www-data rra ( I dont even have this rra folder )
sudo chown -R www-data:www-data logs

OK and i guess this is optional ( didnt do that either )
sudo wget http://download.cactiusers.org/downl...ugin-arch.gzip
sudo tar xvzf cacti-plugin-arch.tar.gz

You must install the wddx PHP5 module. Run

Code:

yast

and search for it.

Its installed

The only wddx in yast is: php5-wddx ... I think it was installed by cacti (dependenci)

Explanation:

sudo chown -R www-data:www-data rra
sudo chown -R www-data:www-data logs

With these command you give Apache write permissions to the selected directories.
It is more save then chmod 777 for instance.

Note:

www-data:www-data is for Debian Linux.

Replace www-data:www-data with apache:apache for RedHat like systems.
(RHEL, CentOS & Fedora).

Replace www-data:www-data with www:www for Suse Linux.
