Cacti wants do re-install older version
WirthmU opened this issue · comments
Describe the bug
About a month ago I did upgrade to the latest version of Cacti and Spine (v1.2.27) and everything went fine and was running as expected.
For over a week I did not look at the cacti server and now when I log into it, it does so with the installation wizzard for Cacti version 1.2.10, which is in fact a downgrade that is not recommended.
Desktop (please complete the following information)
Headless PC
- OS: [e.g. iOS]
Ubuntu 20.04.6 LTS - Browser [e.g. chrome, safari]
Firefox - Version [e.g. 22]
Do you have Cacti RPMs/DPKs from a packager also installed?
That would do it. It's likely you did an update and reversed a bunch of things.
Better reupgrade
That could be. Maybe I have installed it once by apt-get install.
So just re-install v1.2.27?
Ant then, what can I do to prevent this in the future?
Can I just apt-get purge cacti or would this destroy everyting including my cacti database and all templates etc.?
Yea, you have to be careful uninstalling as it will dispose everything. From my perspective, there are a lot of mod's on Ubuntu that complicate a native install, but also conform to Debians rules.
If it were me, I would backup the database using mysqldump and of course backup your RRDfiles, then remove just the Cacti component and then re-install Cacti natively. I'm sure that the spine binary will be fine, though there have been a lot of fixes post 1.2.10 there as well.
For someone like myself, this is a breeze, but for you, it'll be more work. If you don't want to downgrade the database to give you time to test, just update the file cacti_version in the include folder to reflect 1.2.27. That way the database will not be downgraded.
I don't have time to walk you through it, you know day job, but maybe you can get some help from someone like @bmfmancini whose favorite distribution is Debian/Ubuntu.
Could I ask you @bmfmancini for some advice to resolve my problem:
get rid of the ubuntu cacti and spine packages and re-install the latest v1.2.27 cacti version natively.
Hey!
Sorry for the late reply been on vacation !
Ok I would follow this procedure make sure you do a backup !!!!
1.) copy /usr/share/cacti/site/include/config.php
2.) you can copy all off the graph files in /usr/share/cacti/site/rra to another folder so you can copy them back later
3.) mysqldump cacti > cacti.sql ( dump the DB you will be able to reimport it later)
4.) apt-get remove cacti && apt-get purge cacti ( this will uninstall caccti and purge all related files)
5.) install cacti via source you can use my script to help you https://github.com/bmfmancini/cacti-install-wizard
6.) re-import database mysql cacti < cacti.sql which will restore your settings
7.) copy the rra files to the new rra folder directory
again verify each step for errors I installed the package on 23.04 to test these instructions so yours may vary
Hello and thank you for your support @bmfmancini !
I will give it a try tomorrow using your procedure and script and let you know about how it worked.
Just a question upfront - since cacti still is running and polling. How would I stop the cacti poller without having access to the cacti website before so I can quietly backup the database?
you can either stop cron
systemctl stop cron
or remove the cacti file in /etc/cron.d/cacti
the wait for the file poll to finish
it would also be worth going to
console >> settings >> poller and disable data collection enabled this will disable the poller in the app as well
just ensure to flip it back on when you re-import the db
The last is not possible since I can not access the console because when I try to login it asks me to upgrade to version 1.2.10 immediately.
I have read that one can disable polling by changing the value in the database table "settings", named "poller_enabled" and set it to disabled.
It worked well so far and I finish up with the setup screen with Cacti Version 1.2.27.
I can begin with pre-installation checks whichj look good so far (just a few MySQL settings in orange).
Unfortunately the Installation Type / Upgrade screen comes with a warning - it looks like a downgrade from 1.2.29 to 1.2.27. In fact in your script I accepted to install the latest version.
What would you recommend?
Correction:
I changed the version in cacti_version to 1.2.29 and then I could login directly into cacti. It looks like it is working now (cacti v1.2.29 and spine v1.3.0).
I also had to re-build the poller and to change a number of paths to reflect the change of the installation to the /var/www/html/cacti/-Folder.
I could fix everything now. My cacti is up and running again.
Thank you @TheWitness and @bmfmancini for your support
Great!!!
Enjoy cacti!
I need to open this issue up again since I had to use the same procedure on a different instance of cacti on another server.
It looks like using the script of @bmfmancini went through well to the end but then I am unable to access the web console. Whether or not I do re-import the old cacti database or not - http://127.0.0.1/cacti only results in a 404 Error "Not Found" and "The requested URL was not found on this server."
The installation is in the default path /var/www/html/ and cacti/cacti for database and user.
However if I point the browser to http://127.0.0.1/html/cacti/ I get this:
Check your config.php make sure the base path is set to where you have cacti installed
The settings in the config.php file were correct.
However, I noticed that there was an issue with the cacti password setting in the old cacti mysql database which I did reload after running your setup procedure.
When I did set the password for the cacti user in mysql everything went as expected.
Now the system is well and running again.
I might ask you @bmfmancini again for another topic, since you are very knowledgable about Ubuntu and Cacti.
My headless PC is running Ubuntu 22.04.4 LTS and I am asked to upgrade to Ubuntu 24.04.1 LTS. Is this reasonable to do or are there things to be cautious about?
there should be no problems you of course should have a backup
