  Hi Dror,

  Try without the line ExecRestart=/bin/kill $MAINPID - apparently it's not supported by systemd anymore and also not necessary. And if this doesn't help we'd need more information: What did you try so far? What is the error msg? What is your system?

  Best,

  hi

  Im running ubuntu 18.4 on aws

  I managed to install jstos and run it manually

  first I got error 203 user - I changed the user to ubuntu (is it ok?)

  then I started the auto-start and checked the status and I got this error massege:

  -----------------------------------------------------------------

  ● jatos.service - JATOS

    Loaded: loaded (/etc/systemd/system/jatos.service; enabled; vendor preset: enabled)

    Active: activating (auto-restart) (Result: exit-code) since Sun 2020-06-07 21:53:42 UTC; 4s ago

   Process: 7214 ExecStopPost=/bin/rm -f /jatos/RUNNING_PID (code=exited, status=0/SUCCESS)

   Process: 7213 ExecStart=/jatos/loader.sh start (code=exited, status=203/EXEC)

   Main PID: 7213 (code=exited, status=203/EXEC)

  ubuntu@ip-172-31-17-88:~$

  ----------------------------------------------------------------

  I understand that the problem is with the ExecStart line but I cant figure what is the problem

   this is my script:

  _________________________________

  [Unit]

  Description=JATOS

  After=network-online.target

  # If you use JATOS with an MySQL database use

  #After=network-online.target mysql.service

  
  

  [Service]

  PIDFile=/jatos/RUNNING_PID

  User=ubuntu

  ExecStart=/jatos/loader.sh start

  ExecStop=/bin/kill $MAINPID

  ExecStopPost=/bin/rm -f /jatos/RUNNING_PID

  Restart=on-failure

  RestartSec=5

  
  

  [Install]

  WantedBy=multi-user.target

  thank you

  Hi!

  This line of your logging seems to explain your problem:

  Jun 07 21:53:42 ip-172-31-17-88 systemd[7213]: jatos.service: Failed at step EXEC spawning /jatos/loader.sh: No such file or directory

  Somehow the path to the loader.sh seems to be wrong. Is your JATOS installed in /jatos/?

  hi

  1. jatos is istalled on /jatos/ (fig 1)
  2. the User in the script is User=ubutntu is it ok?
  3. maybe something that will help us, when I start the loader the terminal is "stuck" in the process and I dont get a command line after running the loader (jatos works fine until I close the terminal)( fig2)
  

  

  thanks

  Hi dror,

  Looks like you installed JATOS in a folder 'jatos' within your user's home folder. Since your user is called 'ubuntu' I guess the path to your JATOS folder is '/home/ubuntu/jatos'. But you can check that by typing 'pwd' while being in your 'jatos' folder.

  Best,

  worked like a charm

  I also had to change the user to root and give rw permission to loader.log

  thank you very much
