Linux Service in Debian 10

[cwangv]

Hi,
I have installed Mango Automation software v3.6.4 on a HP Stream 13 with Debian 10 (64 Bit version) and Open JDK 11.0.4.
I can manually start Mango software from terminal without problem.
I ran into trouble when i tried to setup Linux Service. I found a similar problem on the forum which has a status code of 126 but mine
has got status code of 127.
Below is what i have encountered:
I followed the instructions on how to setup a Linux service and when i ran the status command, below is what i get from the terminal:
-

below is my mango service file content:
(i played with the path for the commands but ended up with the same message)

$stop ; $start
RETVAL=$?
;;

echo "Usage: sudo service{ start | stop | restart | reload | condrestart}"
RETVAL=1
;;
esac
exit $RETVAL*

Please let me know if the service message is correct. If it is not, what do I need to change to make it work.

Thanks in advance.

Hi cwangv,

Are you able to launch Mango from the command line?

sudo /vwang/mango/bin/ma.sh start ?

[cwangv]

@phildunlap
No, Phil.
But i can do
sudo ./mango/bin/ma.sh start.

I did try using the 'mango/' without '/vwang' in front of it in the mango service file. but same message.

[phildunlap]

It sounds like maybe the path to Mango is wrong. Maybe the Mango directory is /home/vwang/mango/ ? Can you share the output of running pwd from wherever running sudo ./mango/bin/ma.sh start worked?

Hi, Phil
Here is the output:

vwang@debian-mango:~$ sudo ./mango/bin/ma.sh start
[sudo] password for vwang:
MA_HOME is /home/vwang/mango
vwang@debian-mango:~$ ma-start: MA started with Process ID: 7580

It started successfully.
I actually went into the mango service file and added '/home/vwang' into the path. but same message.
Should at least the service status indication part work even with wrong path for the .sh file?

thanks.

Hi, Phil
Success!
In my last reply, I said i added 'home/vwang' in the path of the .sh files but it still didnt work.
I did a restart after that, and it is working now.
Here is the output just in case anyone wonders what the 'Ok' message looks like:

Thanks again for your prompt responses!
