Description

misp-modules - INFO - Launch MISP modules server from current directory.
misp-modules - WARNING - Helpers failed cache.py due to Redis not running or not installed. Helper will be disabled.

All Redis settings were setup correctly and working, inc in MISP /servers/serverSettings/MISP. Redis is located on another AWS instance. Connectivity ok. Setting REDIS_BACKEND='redis.cache.amazonaws.com', REDIS_PORT=6379 and REDIS_DATABASE=13 in /var/www/MISP/venv/bin/activate did not help.

Edited /etc/systemd/system/misp-modules.service directly and added in the [Service] section
Environment="REDIS_BACKEND=redis.cache.amazonaws.com"
Environment="REDIS_PORT=6379"
Environment="REDIS_DATABASE=0"

run
systemctl daemon-reload
and
systemctl restart misp-modules

no more warning. The issue has bene fixed by editing misp-modules.service

Research direction

Start with cache.py and inspect how it reads Redis settings when misp-modules runs under systemd. Compare that behavior with the environment variables added to /etc/systemd/system/misp-modules.service, then verify the service starts without the cache.py warning and connects to the configured Redis instance.
