I'm trying to follow the Redis installation process that was discuss in this article of digital ocean, for in WSL(Windows Sub-System for Linux). The Ubuntu version installed is Ubuntu 18.04.

Everything in redis installation is fine but when I tried to run this sudo systemctl start redis I got this message.

System has not been booted with systemd as init system (PID 1). Can't operate.
Any Idea on what should I do with that?
Instead, use: sudo service redis-server start
I had the same problem, stopping/starting other services from within Ubuntu on WSL. This worked, where systemctl did not. 
And one could reasonably wonder, "how would you know that the service name was 'redis-server'?" You can see them using service --status-all
                Yes.. I been using this too since I wrote the problem, that one from the comment also has a comment that help

                Great, thank you very much. This work for most all services that have been install in WSL environment while we cannot use systemctl to start|stop|restart services.

                Given this is the highest rated answer it would have been nice to see a little more info what happens here. To my understanding service is an abstraction and can fall back to either init.d (sysv init) or systemd which as the question implied does not work. serverfault.com/questions/867322/…

                fraleone, since it was my answer, I'll try to address your concern. To be clear, the question was about an error trying to start Redis (on WSL specifically), where using the common start command documented elsewhere, systemctl start redis, was not working for the OP. It wasn't working for me, either. I found this alternative (redis-server start) and came here to offer it as an answer. I'm glad it's helped others. But I wasn't/am not in a position to explain "what happens here", or why it counters your expectations. Feel free to elaborate as you may find more, or perhaps others will.

                You can also call the needed commands from ".profile" already at boot up time, see the similar issue for docker “sudo systemctl enable docker” not available: Automatically run Docker at boot on WSL2 (using a “sysvinit” / “init” command or a workaround) which also explains in detail why you need to use "service" here instead of systemd.

sudo /etc/init.d/redis start
as of right now we do not have systemd in WSL
Or sometime it might be redis-server, like:
>> sudo /etc/init.d/redis-server start
Starting redis-server: redis-server.
Just do a ls, like: ls /etc/init.d
                From a quick search WSL2 is not booted with systemd.  There is a workaround here though which I have not tested.  github.com/microsoft/WSL/issues/994#issuecomment-502055417

                sudo /etc/init.d/redis-server start fixed the problem after all other commands had failed. I am on WSL.

                you'd also have to start the distro. So I have 2 terminals one runs docker and the other one I use for my work

If you are using Docker, you may try an image that has Ubuntu with System D already active with this command:
docker run -d --name redis --privileged -v /sys/fs/cgroup:/sys/fs/cgroup:ro jrei/systemd-ubuntu:18.04
Then you just need to run:
docker exec -it redis /bin/bash
and there you can just install Redis, start it, restart it or whatever you need.
Total newbie here - after trying most of the above suggestions, the command that worked for me was sudo service apache2 --full-restart and the web server started up.
Maybe the error came up because I have been following lots of setup instructions without a reboot/restart. I'm working on Ubuntu 20.04 in WSL2 using Apache2 Debian.
For WSL2, I had to install cgroupfs-mount, than start the daemon, as described here:
sudo apt-get install cgroupfs-mount
sudo cgroupfs-mount
sudo service docker start
