Converting from Debian/Ubuntu Package Install to Cacti Source-Based Install

This guide outlines the steps to convert from a Debian/Ubuntu package install of Cacti to a source-based install.

If you are looking to run the latest version of Cacti a source based installation is the way to go Often the cacti team releases feature and updates that the packages lag behind on also source based installs provide more control for administrators than a package installation

This document will provide the steps on how to convert a system that has been installed via package on a Debian/Ubuntu system while retaining your settings and data

Important ! Before running these steps ensure you have a system backup !

Note these steps can vary between Ubuntu/Debian versions however the process flow would be the same

Step 1: Stop Cron/cactid Daemon

ensure that cron is stopped to prevent any conflicts during the transition and to prevent the poller from running while backing up the system systemctl stop cron If you have installed the cactid daemon

systemctl stop cactid

Step 2: Backup Configuration File

cp /usr/share/cacti/site/include/config.php /path/to/backup/config.php

Step 3: Backup Graph Files

You can copy all of the graph files in /usr/share/cacti/site/rra to another folder so you can copy them back later.

cp -r /usr/share/cacti/site/rra /path/to/backup/rra

Step 4: Dump the Database

Create a backup of the Cacti database.

mysqldump cacti > cacti.sql

Step 5: Uninstall the Package Version of Cacti

Remove and purge the Cacti package to ensure no conflicts with the source-based install.

apt-get remove cacti && apt-get purge cacti

Step 6: Install Cacti via Source

Follow the appropriate steps to install Cacti from source. Refer to the official Cacti https://github.com/bmfmancini/documentation/blob/develop/Installing-Under-Ubuntu-Debian.md

Step 7: Re-import the Database

Once Cacti is installed from source, restore your previous settings by re-importing the database.

mysql cacti < cacti.sql

Step 8: Restore Graph Files

Copy the backed-up RRA files to the new RRA folder directory in your source installation.

cp -r /path/to/backup/rra /new/cacti/source/path/rra

---

Once these steps are completed, your Cacti installation will be switched from a package-based install to a source-based one, while retaining your configurations and graphs.
