Mlapi start as a service

[JasonBorn]

Hi there,
i cant start the MLAPI as a service. I get this error:

Code: Select all

● mlapi.service - Machine Learning API service
     Loaded: loaded (/etc/systemd/system/mlapi.service; enabled; vendor preset: enabled)
     Active: activating (auto-restart) (Result: exit-code) since Sat 2021-06-05 09:43:29 CEST; 1s ago
    Process: 17336 ExecStart=/var/lib/zmeventnotification/mlapi/mlapi.py -c ./mlapiconfig.ini (code=exited, status=209/STDOUT)
    Process: 17337 ExecStartPost=/bin/sh -c umask 022; pgrep mlapi.py > /var/run/mlapi.pid (code=exited, status=209/STDOUT)
   Main PID: 17336 (code=exited, status=209/STDOUT)

Jun 05 09:43:29 mlapi systemd[1]: Failed to start Machine Learning API service.

Is there any special option to start it? Manually the MLAPI starts.


EDIT:
systemctl status mlapi.service shows:

mlapi doesn't come with a generic service activation. You'll have to write or customize your own.
The mlapi.service file I provide is one that works for me (Ubuntu 20) and the install_as_service.sh script set its up (which explains the disclaimer in the script).

So I am not sure how you have defined your service file but I'd suspect that is where you should start.
You may also want to search for "Failed at step STDOUT spawning /bin/sh" on Google. One option is "/bin/sh" is actually "/usr/bin/sh" (in my case)

All that being said, there may be others who are well versed in writing service files who may know what is going on.
