Cacti

Initial install:

# Make sure the stack is installed and running first
apt install apache2 mariadb-server
# Install and auto-configure Cacti
apt install cacti

Visit http://localhost/cacti/ and follow the final install process.

Cacti on bullseye appear to suffer from installation issues:

• In case of infinite redirects, go to /cacti/auth_changepassword.php and change the initial password (admin:admin), respecting the password constraints (e.g. Admin123!)

• MySQL TimeZone can be populated through mysql_tzinfo_to_sql /usr/share/zoneinfo/|mysql mysql

• Cacti-Install insists on setting date.timezone, e.g. date.timezone = "Europe/Paris" in /etc/php/x.x/{apache2,cli}/php.ini

• Cacti-Install insists on getting write access to /usr/share/cacti/site/{resource,site}/, you can chown -R root:root back after the install
