Hi @detleffolke,

Can you please try to start the service, once it fails please run

journalctl -xe

it will provide you with the reason behind it failing to start.

Additionally, you can try 

nano /etc/init.d/kafka

and provide me with the contents of the file here?

Kind regards,
Kalin D.

    Hi Kalin,

    I follow this tutorial “How To Install Apache Kafka on Ubuntu 18.04”.
    There is no kafka file in /etc/init.d.

    This are the content from journalctl -xe:

    Aug 20 14:15:19 ubuntu-server sudo[16665]: pam_unix(sudo:session): session closed for user root

      Hi @detleffolke,

      I see, thank you for the reply.

      To further try and solve this, can you please perform a few things for me and provide me with the result here

      sudo free -mh

      sudo nano /etc/systemd/system/zookeeper.service

      sudo nano /etc/systemd/system/kafka.service

      sudo grep kafka /etc/passwd

      I’m awaiting your reply to try and further help you in the situation.

      Kind regards,
      Kalin D.

          Hi,
          I had the same problem with a new VM and the problem was Java was not installed. I understood that running directly the command

          /bin/sh -c ’/home/kafka/kafka/bin/kafka-server-start.sh /home/kafka/kafka/config/server.properties > /home/kafka/kafka/kafka.log

Look in /etc/systemd/system/<kafka-unit-file>.service

You should switch to the User mentioned there and set PATH configured in that file. Then try running the command mentioned in ExecStart. You should find that the command can’t be found and this is why you are getting that error.

If that doesn’t track down the problem, I’ve actually written up a pretty extensive runbook on how to debug systemd issues. Take a look and leave me a comment if things still aren’t working for you.

Hi @detleffolke ,
I also encountered this problem today.
I added the environment path under [service]and it can run normally！

Environment="PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/bin/java/:/usr/local/jdk/jre/bin"
