problem with auto start jatos on server

drorgarbi

Hi

I maneged to start jatos manually on AWS

but when I try creating the script for auto start jatos it fails

this is the 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_linux_java/RUNNING_PID

User=admin

ExecStart=/jatos_linux_java/loader.sh start

ExecStop=/bin/kill $MAINPID

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

ExecRestart=/bin/kill $MAINPID

Restart=on-failure

RestartSec=5

[Install]

WantedBy=multi-user.target

thank you for your help

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,

Kristian

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)

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:

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/?

Best,

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,

Kristian

worked like a charm

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

thank you very much
