== Upgrade == | |||
There is an upgrade procedure on Cacti's website (http://www.cacti.net/downloads/docs/html/upgrade.html), I'm not sure I agree with the order of the steps, in that I suspect it could prolong the time for which you can't capture data, but otherwise it seems fine. I don't know that my procedure is any better, but it works for me. | |||
Be aware that I originally installed Cacti from the Ubuntu repository, which I now tend to think is a bad idea for anything other than core OS components (as it can be years out of date, and installs to different locations than you would do manually, making subsequent upgrades a royal pain in the ass, I digress). So your files may not be in the same location as above (originally I had a <code>site</code> subfolder). | |||
# Download the latest version, and uncompress | |||
#* EG <code> cd /usr/share </code> | |||
#* EG <code> wget http://www.cacti.net/downloads/cacti-0.8.7i.tar.gz </code> | |||
#* EG <code> tar -xzvf cacti-0.8.7i.tar.gz </code> | |||
# Update the MySQL config in the new version | |||
#* EG <code> vi cacti-0.8.7i/include/config.php </code> | |||
# Backup your existing database | |||
#* EG <code> mysqldump -u root -p -l cacti > /home/user/cacti-v0.8.7e.mysql </code> | |||
# Check the poller cron job, if the poller.php path is changing, add an entry for the new path (we can remove the old path once everything is working) | |||
#* EG <code> vi /etc/cron.d/cacti </code> | |||
# Check the path that RRA's are expected to go to | |||
#* Compare the <code> $config["rra_path"] </code> value in <code>/include/global.php</code>, if necessary override in <code>/include/config.php</code> | |||
# Check the Apache config | |||
# Switch the folders around | |||
#* EG <code> mv cacti cacti-v0.8.7e </code> | |||
#* EG <code> mv cacti-0.8.7i cacti </code> | |||
# Browse to your installation, and upgrade the database | |||
# Once complete go to System Utilities > View Cacti Log File, and check everything is looking OK | |||
# Remove additional path from crontab (if you added one) | |||
If you've upgraded an installation that was installed automatically with <code>aptitude</code> or <code>apt-get</code> then you'll need to stop it being mangled/downgraded in the future, to do so run | |||
aptitude hold 'cacti' | |||
