How to make Redis start with the server?

Question

linux

After rebooting the VPS, Redis for some reason does not start. Redis itself works in unixsocket mode, here is its config:
redis.conf: https://pastebin.com/pzsC3PSq
service redis status:

● redis.service - Redis In-Memory Data Store

Did I understand correctly that it does not start due to the absence of the /var/run/redis/ folder? There I should have a redis.sock file, as I indicated in the config.
Question: how to make that when restarting the server, Redis itself creates this folder?

Answer 1

in cron, your script should run on the @reboot event.
in the
mkdir /var/run/redis script and the required chown/chmod to this folder.

Answer 2

if it starts like this:
then add it to autoload
if it doesn’t start after start, then find out why, autoload has nothing to do with it

Answer 3

Maybe there are not enough rights to write the log file, check the permissions, try setting 700 for the log file
chmod 700 /var/log/redis/redis-server.log

Answer 4

This is because /var/run/ you have tmpfs and all content naturally disappears after a reboot. Correct the path from /var/run/redis to /var/run in the redis config and everything will work
