Some cacti/mysql problems

Braynid · 10-06-2006, 10:21 AM

Hello, i have this Ubuntu RC 6.06 and i have installed cacti on it. The problem is that when i try to create a graph i get this error message. Can you help please?

I have no idea what to do with them. I've looked up the given lines in the given files but they don't tell me much. I suppose it's some problem with my mysql configuration...

this is a php generic message, not cacti specific so any hits on google for that error should be ok: http://codex.gallery2.org/index.php/...t.27s_wrong.3F

and of course the third message is there because of the fact that the other error messages have been sent. as such it can't send more headers... that'll disappear of it's own accord.

btw. i'm not a huge cacti fan... much prefer opennms all round...

Well i've googled it some more and i only get references for 'codex gallery2' that i don't use, and the advice to update 'zend_optimizer' that again i don't use. Ca you be more specific please?
About opennms, you say it's better then cacti?

oh yeah, i misread that link, i thought they were offering PHP config changes... my bad.

right so i'm stuck having to fix this now right?

appears that this would be a php 4.4 issue, and you can either upgrade to 5.x, downgrade to 4.3 or simply make php ignore these notices and not screw everything up. seems that this is done by adding a line saying

Code:

error_reporting = E_ERROR | E_WARNING | E_PARSE

i.e. ignore E_NOTICE's which is what you have...

First off opennms is probably way overkill for anything but the largest setups.

Second, go to the cacti website and get the tarball. It's MUCH easier to install. I didn't get y ou particular message, but I did get several others with the Ubuntu .deb.

@acid_kewpie: thanks mate for the support! One question, where should i add the given line? I've tried to put it in '/etc/suphp.conf' but i still get the error. By the way if i upgrade to 5.x all my old databases are gone?
@ghight I've tried that but i have to compile some other .tar.gz packages and they don't compile right so...

acid_kewpie · 10-07-2006, 01:28 PM

ahh crap never said did i..? add it to php.ini, normally in /etc i think

Braynid · 10-08-2006, 12:27 AM

Ok, i've done some work and now the configuration of my server is:

Code:

Apache/2.0.55 (Ubuntu) PHP/5.1.2 mod_ssl/2.0.55 OpenSSL/0.9.8a

I still have the error so i've added the code in '/etc/php5/apache2/php.ini' the same thing. i've tried to put it in '/etc/php5/cgi/php.ini' to and still nothing.
So... it's quite strange.

After some research i have this question. Should i remove cacti, reinstall php and then reinstall cacti ? Would this work? And i don't want to lose my database... so what's to be done?

You shouldn't compile anything. Install the prereq packages as required then unpack the cacti tarball to the webserver root. Pretty simple really.
