Cacti intallation on Ubuntu 9.04

[cjblade54]

Here is the screen shot for poller cache

Well, i am not sure if this presents a problem or not. I installed the cacti under /var/www/ directory. Basically download the tar file and untar it under that /var/www/ folder. Is that okay?

Are you sure this is from packages, and not source ? If it's installed from packages, you should have a path to rra like this "RRD: /usr/share/cacti/site/rra"

What happens if you clear the poller cache and wait for another poll ?

[cjblade54]

Ok - could you also do

From terminal

cd /usr/share/cacti/site/rra

ls -ln

Post output

Thanks

Yeah... this is where i think my problem is.... i have my cacti installed under /var/www/ ..... so when i tried

Code: Select all

cd /usr/share/cacti/site/rra

the directory does not exit.

Ok, well, let's try

cd /var/www/cacti/rra

ls -ln

Here is what happened when i run whereis rra/

Yeah.. i tried to installed by using "apt-get intall cacti", it didn't work. it gave me so many problems that i just DLed the source and unpacked it in /var/www/ folder.

[cjblade54]

Ok, well, let's try

cd /var/www/cacti/rra

ls -ln

Post output

Code: Select all

root@magneto:/bin# cd /var/www/cacti/rra
root@magneto:/var/www/cacti/rra# ls -ln

Ok, I think if you tried with packages first, and then failed, it looks like you may have mashed your system.

What sort of errors did you get ? You should have used

sudo apt-get install cacti-cactid

[mcutting]

Ultimately, RRDTool is not creating RRA's, as it's segfaulting - explains why this directory is empty. If you installed from packages, then Net-SNMP, RRDTool and everything else you need is setup for you.

ok.. so i took your advice and removed the snmp and rrdtool manually. (in fact, i manually installed it when the files were found) and reinstall the cacti-cactid by using apt-get. It asked me if i wanted to keep the same source file which i did. The install went well until the end ... it shows...

Please inform the package maintainer about this problem.
Not replacing deleted config file /etc/cacti/apache.conf

I used the tar file from the official cacti site http://www.cacti.net/downloads/cacti-0.8.7d.tar.gz and untar it in var/www/ directory.

LOL... so it looks like its getting some where... was testing out the benchmark command "php poller.php" and was able to get the following result.

php poller.php
06/08/2009 01:15:47 PM - POLLER: Poller[0] WARNING: Cron is out of sync with the Poller Interval! The Poller Interval is '300' seconds, with a maximum of a '300' second Cron, but 10775 seconds have passed since the last poll!

So, i checked my graphs...and also checked my log file...
it looks like i am getting somewhere.. however, i am not getting any graphs... going to do some more research and reading and see if i can find out what else i can do to fix this. Comments and advise are welcome.. lol

[cjblade54]

Finally got it fixed. I had to go in the crontab and change the command field. It was pointed to the wrong directory.

Hey i'm trying to install Cacti on Ubuntu 9.04 server too. I'm completely new to Linux and am not a programmer, so I have a hard time figuring out what commands to use.

I was following the guide at http://www.cacti.net/downloads/docs/htm ... e_php.html but its for unix in general... I've managed to nearly install all the required packages but am not finding some or equivalent of some of the file modifications that need to be done.

Do you think you could throw together a quick walkthrough of the commands needed to get Cacti up and running on Ubuntu 9.04?

Thanks in advance if you can do this...

[aldibi]

I had all sorts of issues, particularly doing then upgrade where the download does not have some essential patches.

I wrote up a tutorial to help - http://open4energy.com/tutorials

Hope there may be some use in it

The easy way to install cacti on Ubuntu is using the default version installed from apt.

Code: Select all

sudo apt-get install cacti cacti-spine php5-snmp rrdtool

that should do it, then follow the instructions on screen.
set a password etc for the cacti mysql database.

Now the default install is in /usr/share/cacti
dont bother completing the install via the webpage (http://server/cacti/)

now enter the install dir and move the old cacti out of the way.

Code: Select all

cd /usr/share/cacti
mv site old.site
mv resources old.resources

wget http://www.cacti.net/downloads/cacti-0.8.7e.tar.gz
tar zxf cacti-0.8.7e.tar.gz

mv cacti-0.8.7e site
mv site/resource .
mv site/rra .

cd site
ln -s ../site/resource
ln -s ../site/rra
chown -n www-data.www-data resource rra

cp /usr/share/cacti/old.site/include/config.php /usr/share/cacti/site/include/config.php

chown -R www-data.www-data /usr/share/cacti

now edit the file with your fav editor .. mine is vi..

Code: Select all

vi /usr/share/cacti/site/include/global.php

scroll down to line 59 or so where it shows:

Code: Select all

$config['url_path'] = "/";

edit it to look like:

Code: Select all

$config['url_path'] = "/cacti/";

Now everything is according to ubuntu standards except the rra location which is usually in /var/lib/cacti/rra/ but i like to make easy backups of /usr/share/cacti and know i got everything.

Last thing is to update the mysql database.

Code: Select all

 
cd /usr/share/cacti/site

mysql -u root
 drop cacti
 create cacti
 exit

mysql -u root cacti < cacti.sql

Now you are done with the basic install of cacti.

To install cacti-plugins..

Code: Select all

cd /usr/share/cacti/

wget http://mirror.cactiusers.org/downloads/plugins/cacti-plugin-0.8.7e-PA-v2.5.zip
unzip cacti-plugin-0.8.7e-PA-v2.5.zip

mysql -u root cacti < pa.sql

cp -Rpf files-0.8.7e/* site/

now edit the file with your fav editor .. mine is vi..

Code: Select all

vi /usr/share/cacti/site/include/global.php

scroll down to line 59 or so where it shows:

Code: Select all

$config['url_path'] = "/";

edit it to look like:

Code: Select all

$config['url_path'] = "/cacti/";

Code: Select all

chown -R www-data.www-data /usr/share/cacti

and you are set for cacti + plugins...
