[solved] Redis-Server not sintalling correctly (rspamd)

Hi, playing around with lxc virtual machine feature and dedicated IP for the vm.
It is not a container! Though i have been running ispconfig 3 in a lxc container the last years.
Fresh install on 20.04 cloud-init image with current full auto script.

Code:

systemctl status redis-server
● redis-server.service - Advanced key-value store
     Loaded: loaded (/lib/systemd/system/redis-server.service; enabled; vendor preset: enabled)
    Drop-In: /run/systemd/system/service.d

"/var/log/redis/" folder does not contain the "redis-server.log".
I touched it and tried with chown redis:adm and/or redis:redis .
Line 175 = "logfile /var/log/redis/redis-server.log"

Code:

-rw-r--r-- 1 redis redis 395 Jul 21 17:58 /var/log/redis/redis-server.log
or
-rw-rw-rw- 1 redis redis 395 Jul 21 17:58 /var/log/redis/redis-server.log
-rw-rw-rw- 1 redis adm 395 Jul 21 17:58 /var/log/redis/redis-server.log

Changed "Supervised no" to "Supervised systemd" in redis.conf but that wasn't it either.

 

Forgot to add the setup log parts, i run the setup with debug flag.

Code:

wget -O - https://get.ispconfig.org | sh -s -- --use-ftp-ports=47710-47810 --no-dns --use-unbound --no-quota --no-roundcube --no-mailman --no-pma  --unattended-upgrades --debug

Code:

There was no other error in the Setup log.

Could use some pointers as to why the redis-server is failing with the same error, no matter which distro i use.
The script installs just fine, except for the redis-server.
I have been running redis-server for nextcloud, inside a lxc container without problems, but why i would face such problems inside a VM which is supposed to act like a bare metal leaves me baffled.

Either because of systemd or redis-server config, how can i get more detailed info why the startup is failing?

 

can you create a file? i.e.

Code:

 touch /var/log/redis/test

?

 

Sorry for late reply, just come back to spend some time on this problem.

Yes i can touch and create the log file and journactl shows that it is some sort of permission problems that i have not yet figured out.
I did not witness this at first but systemctl startup error is either reporting

Code:

redis-server[297187]: Can't open the log file: Read-only file system

or Permission denied, when testing other chown options with,

Code:

redis-server[297183]: Can't open the log file: Permission denied

This is happening with current Ubuntu focal Server.

 

Stopped by to report this was an error of the Host System that must have happened during the upgrade from 18.04 to 20.04
