another Ubuntu install/upgrade method for cacti-0.8.7e

[gmork123]

I prefer ubuntu packages when possible, but they are sometimes a bit outdated. So here's my method to have to most actual version of cacti, but with config/data files in the right places, according to ubuntu/debian standards.

(btw: I did this because I had a ping icmp problem, "Unable to create socket" with my old version, which was solved by this upgrade.)

I assume the original ubuntu package is already installed & configured: packagename is cacti and for spine: cacti-spine or cacti-cactid (depening on ubuntu release)

I unpacked cacti-0.8.7e.tar.gz in /usr/share/cacti and did the following

Code: Select all

cd /usr/share/cacti
mv site site.old
mv resource resource.old
ln -s cacti-0.8.7e site
mv site/resource/ .
ln -s resource/ site/
cp site.old/include/config.php site/include/
mkdir tags ; cd tags ; ln -s ../cacti-0.8.7e/ 0.8.7e; cd ..
wget http://www.cacti.net/downloads/patches/0.8.7e/cli_add_graph.patch
wget http://www.cacti.net/downloads/patches/0.8.7e/snmp_invalid_response.patch
patch -p1 -N < cli_add_graph.patch
patch -p1 -N < snmp_invalid_response.patch

After this the webpage showed the database upgrade page and everything worked fine.

I have no special scripts and work with the cmd poller, not with spine, so things might be somewhat more complicated in other situations.

Thanks for sharing.
I'll try to reproduce and perhaps update the docs with those hints

The official way would be to install the latest cacti from ubuntu's sites.
So to keep cacti in latest, i added the 'lucid' distro into my apt-get packages.

add into
/etc/apt/sources.list

Code: Select all

deb http://archive.ubuntu.com/ubuntu lucid main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ lucid-updates main restricted universe multiverse
deb http://security.ubuntu.com/ubuntu lucid-security main restricted universe multiverse

add into
/etc/apt/preferences

Code: Select all

Package: cacti
Pin: release a=lucid
Pin-Priority: 900

Package: cacti-cactid
Pin: release a=lucid
Pin-Priority: 900

Package: cacti-spine
Pin: release a=lucid
Pin-Priority: 900

Package: rrdtool
Pin: release a=lucid
Pin-Priority: 900

Package: *
Pin: release a=intrepid
Pin-Priority: 100

Package: *
Pin: release a=lucid
Pin-Priority: 10

To explain..

Basicly we added the beta distro package (lucid) archive and configured priority to the different versions of packages.
We choose 'lucid' for cacti & rrdtool packages and set some defaults to not mix up our current ubuntu distro.
900 - forced to choose lucid distro on these packages
100 - set my current intrepid distro as default priority (apt-get should keep using my current system packages)
10 - lower the priority all of lucid's packages below my default.

after that it would be simply..

Code: Select all

apt-get update
apt-get install cacti cacti-spine

This would be the correct way to do it on ubuntu
+ this way would always keep it updated + patched & configured for ubuntu's settings.
Well.. at a date you'll need to change the name of the latest distro

To install PA v2.5 for 8.7e
Download cacti-plugin-0.8.7e-PA-v2.5.zip off the home page.
run

Code: Select all

patch -p1 -N < cacti-plugin-0.8.7e-PA-v2.5.diff

it gave an error in the include/global.php as expected. Either just look at the the rej file and see what needs to be done or for those uncomfortable to do this, i attached the patched global.php

-- note --
Why does it try to patch the version to 8.7c ?
8.7e version already in the global.php

OK, so I did all that was listed by disH except for the plugin part, and it's working just fine.

However, I noticed that the package manager install didn't put anything into /etc/crontab, nor did it add any cactiuser user.

Now, I want to tweak it so that the poller and the cron are both running a 1 min intervals. As soon as I do, it breaks with the "POLLER: Poller[0] WARNING: Cron is out of sync with the Poller Interval! The Poller Interval is '60' seconds, with a maximum of a '300' second Cron, but 300 seconds have passed since the last poll! " error.

So, how can I set up 1 min interval polling with this version and not break it?

You can find the schedule in /etc/cron.d/cacti
i dont use 1min polling but if remember correct, it requires some patching. You can find the info on the forum.

tried this, from karmic...

looks like cacti is working, but can't get any data out of remote machines via snmp now, trying a full update to lucid.

google's mysql-cacti templates are working fine..

still no go with snmp v3 gets

anybody have run into anything like this?

Tried what disH said and ... I get an error when I do the apt-get update says
(losely translated, I got french version) You have reached the maximum descriptions this APT version can handle. (something like that).
Any clues ?

Thank you for the coding..
People normally tried to hide these kind of things but thank you for sharing this with us....

I had that once. If I can remember correctly this simply means that you have too many apt sources with way too many files in them. I think apt can only handle a specific amount of files/sources. Kindof like the Excel limit of 64k rows ...

I try to get fresh cacti install work for Lucid server with PA, but it won't
I follow and mix up lot of method but no one work ...

apt-get install cacti cacti-spine
(look to work if i check http://ipserver/cacti)

then if i try first to apply official patch i get (only first patch example) :

cd /usr/share/cacti/
wget http://www.cacti.net/downloads/patches/ ... raph.patch
patch -p1 -N < cli_add_graph.patch
patching file cli/add_graphs.php
Reversed (or previously applied) patch detected! Skipping patch.
1 out of 1 hunk ignored -- saving rejects to file cli/add_graphs.php.rej

same for all other patch, so i try to install PA first :

cd /tmp/
wget http://mirror.cactiusers.org/downloads/ ... A-v2.6.zip
apt-get install unzip
unzip cacti-plugin-0.8.7e-PA-v2.6.zip
cd /usr/share/cacti/site/
patch -p1 -N < /tmp/cacti-plugin-arch/cacti-plugin-0.8.7e-PA-v2.6.diff

i have three error:

patching file graphs_new.php
Hunk #1 succeeded at 483 (offset 4 lines).

Hunk #3 FAILED at 195.
1 out of 4 hunks FAILED -- saving rejects to file include/global.php.rej

patching file include/global_settings.php
Hunk #1 succeeded at 1186 (offset 1 line).

And the worst is now http://ipserver/cacti only give my blank page !

i think to fix this with :
chown -R www-data:www-data /usr/share/cacti

but it seem to do nothing .
