Execute external bash script on server with blynk))

41

If the external script is not running it can be 1 of several problems:

  1. The js file is not calling the bash script
  2. The bash script has errors
  3. You have a problem with the path
  4. You have a problem with file permissions
42

/bin/su root -c “/usr/bin/screen -dmS blynk /bin/bash /home/zara/blynk.sh”
rc.local detached screen smple
1,2,4 are not
Cause if i launch client manualy it works and lauch script!
I was asking about those lines with child_process. Do they need full path?

43

That is possibly because your local server hasn’t started before the client tries to run from rc.local.

Move the client to the forever-service.

You should assume everything needs the full path.

44

NOPE! Local server is on remote pc, its not same with client
And i see online status hw in app!

45

Ok post the following:

  1. Bash script that calls the client from rc.local
  2. Your js Blynk client file
  3. The bash script
46

Sure but a hour later, im in subway returning home. Ok?

47

Don’t rule out 4 just because it works when you manually start the Blynk client.
Looks like you are possibly root when you are doing it manually and might not be when using rc.local
Take a look at the file permissions for your bash script and maybe

sudo chmod +x bash_file.sh

48

Its already chmoded to hell! With +x and 777

Damd! i think i find error myself))))))

Where?

Are you saying the error is:

echo 1111 >> zhopa.sh

and it should be something like

echo 1111 >> test.txt

51

i foget “!” in blynk.sh before #
Yip that was it!
i corret this error while pasting text here
Now it works great as detachet screen

zara@carpi:~$ sudo screen -ls
There is a screen on:
640.blynk (06.03.2017 17:49:11) (Detached)

It was nessesary to show full path to echo to write something to file…
test.sh wrote script to /root instead of my home directory and i thought it was not work)))))))))))))))))))))))
