Linux Question

systemd cannot run service after running commands

I tried to run systemd using the commands

systemctl enable photogrid.service
systemctl start photogrid.service
in ubuntu 16

The nodejs app itself can run as expected. The service is to ensure that application will auto-start when application crash or server reboot.

The service apparently did not start. So I key in
systemctl status photogrid.service
to see what happened, the below is what I got from the terminal.

‚óŹ photogrid.service - Photogrid
Loaded: loaded (/lib/systemd/system/photogrid.service; enabled; vendor preset: enabled)
Active: activating (auto-restart) (Result: exit-code) since Wed 2016-11-09 04:35:36 UTC; 7s ago
Process: 27523 ExecStart=/usr/local/bin/node /home/ubuntu/photogrid/app.js (code=exited, status=203/EXEC)
Main PID: 27523 (code=exited, status=203/EXEC)

Nov 09 04:35:36 ip-172-31-34-151 systemd[1]: photogrid.service: Main process exited, code=exited, status=203/EXEC
Nov 09 04:35:36 ip-172-31-34-151 systemd[1]: photogrid.service: Unit entered failed state.
Nov 09 04:35:36 ip-172-31-34-151 systemd[1]: photogrid.service: Failed with result 'exit-code'.

This the script that I wrote for the service under the path /lib/systemd/system/photogrid.service


ExecStart=/usr/local/bin/node /home/ubuntu/photogrid/app.js

Basically under ExecStart make sure you point to the correct nodejs executable. For my case it was in a different folder and not /usr/local/bin/node, to check where is your node executable. (Assuming you confirm you have downloaded and install it correctly in linux) use command which node to give you path direction.
