I have installed redis on Ubuntu 16.04 according to the digialtocean guide. It uses systemd and should start on boot.
I can start redis from cli
sudo systemctl start redis
and it works with no error or issue. However when I reboot, redis fails to start. I tried several things I found via googling, nothing worked so far:
- setting Type=forking or Type=notify (or leaving it away entirely like in the guide)
- Adding LimitNOFILE=65536 to get rid of an error (which it does but still fails to load)
There is no clear error in journalctl:

This block is repeated 5 times in the log and then at the end of the log this message appears:
Lubuntu-16-04 systemd[1]: redis.service: Start request repeated too quickly.
Lubuntu-16-04 systemd[1]: Failed to start Redis In-Memory Data Store.
In the redis log I see this:
Creating Server TCP listening socket 192.168.XX.XXX:6379: bind: Cannot assign requested address
I want to allow remote connection, that is why I also bind to "external" IP. Is this causing redis to fail startup? But it works fine when starting manually. What is causing the issue?
