To upgrade Cacti under UNIX style operating systems is very strait forward. To upgrade Cacti on Windows, you should use the instructions in the Link below:
Before you begin, generally both your Apache/NGINX and your Crontab or
systemd based pollers should run as the same account. In most Linux
operating systems these days, that'll be the
apache account. Under
SLES, it'll be
www-run. For this guide, we will use the
but please keep this in mind before starting.
Backup the old Cacti database.
shell> mysqldump -l --add-drop-table --lock-tables=false cacti > mysql.cacti
NOTE: You will probably have to specify the -u and -p flags for the MySQL username and password. This user must have permission to read from Cacti's database or you will end up with an empty backup.
Backup the old Cacti directory with the exception of the RRDfiles which should not need backup.
shell> tar --exclude=*.rrd -zcf cacti_backup_YYYYMMDD.tgz cacti
Extract the distribution tarball.
shell> tar -xzvf cacti-version.tar.gz
Copy the distribution tarball over the existing installation.
shell> /bin/cp -rpf cacti-version cacti
Set the appropriate permissions on Cacti's directories for graph/log generation. You should execute these commands from inside Cacti's directory to change the permissions.
shell> chown -R apache:apache rra/ log/
(Enter a valid username for cactiuser, this user will also be used in the next step for data gathering.)
If you are using the optional feature
Performance > Image Caching, or
Realtime Graphing, then recreate the
cache folder and correct the permissions.
shell> mkdir cache shell> chown -R apache:apache cache

Follow the on-screen instructions so your database can be updated to the new version.
NOTE: That starting with Cacti 1.0, all Data Collectors will upgrade themselves automatically within two polling cycles. If for some reason they do not, upgrade them one at a time using the procedure above.
