I have a distributed implementation of Librenms under Ubuntu :
- 1 server with DB and Apache2
- 1 rrd server
- 5 pollers
After receiving the notifications regarding PHP and Python version, and the alert " Error: Python requirements not met", i tried to upgrade everything
./validate.php output prior to upgrade :
/opt/librenms# ./validate.php

[FAIL] Missing PHP extension: memcached
[FIX]:
Please install memcached
I already have PHP memcached extension installed :
/opt/librenms# apt install php-memcached
Lecture des listes de paquets… Fait
Construction de l’arbre des dépendances
Lecture des informations d’état… Fait
php-memcached est déjà la version la plus récente (3.1.4+2.2.0-1+ubuntu18.04.1+deb.sury.org+20191129).
I have forced the system to use PHP 7.2 using “update-alternatives --set php /usr/bin/php7.2”
And everything is OK
Do you have a kind of process to not forget anything while upgrading php version ?
