Redis configuration multiple users on the same server

[JohnnyBravo]

The installation of redis went fine, also one user is using it on my server. But when I want to enable it to another user(website) on the same server, I get the following error for this command:

systemctl status [email protected]

[/etc/systemd/system/[email protected]:10] Executable path is not absolute, ignoring: -+/bin/sh -c "if [ -d /sys/fs/cgroup/user.slice ]; then mkdir -p /sys/fs/cgroup/user.slice/u...

After

systemctl start [email protected]

redis isn't functioning anymore for all users...
