Upgrading 0.8.7b to 0.8.7g Debian Lenny

[danslarge]

This script is specific to upgrading Cacti 0.8.7b to Cacti 0.8.7g on a GuruPlug server which runs Debian Lenny. I had problems with this mostly because the directory structure is somewhat different between the versions so scripted it. It prompts for the MySQL root password.

Code: Select all
