Is there any way to keep NPM always in running position even if I close my command prompt? I tried using start stop restart method but it does not work out. how can I get out from this?
This is not the NPM goal to launch programs that stay in background.
To do what you want you should start the node process with the following option.
nohup <your command here> &
Example:
nohup node server.js &
nohup: Attach the command to the process with PID 1, that means that your program will be killed only if your reboot the server, or if you kill the process yourself.
&: Launch the process in background, that means that you can still use your prompt.

I have a project that is deployed by a previous dev on a linux server. The environment variables are stored in /etc/systemd/system/gunicorn.service. The file doesn't seem to be present anywhere in the server but still the code runs fine. There are multiple steps to get this file set up but none to read it. I need the information to get it running on my local machine. Any cli commands to read the same?
The directory is in format:
app.py
requirements.txt
README.md
The app.py is the main function and the rest 2 also don't have anything to do woth gunicorn.
Did you try:
sudo cat /etc/systemd/system/gunicorn.service

Sorry for the German question before.
I have the following problem. I search about it in the internet but i did't was successfull.
I wanna run my node script with my npm-dev script.
I execute " npm run dev". Normal like everytime.
Than i got this error message:
It means that node cannot be found.
I can execute via the Terminal my JS-File with "node index". Just all my npm-scrips doesn't work.
I think that i have some problems with the environment variables. But if I execute " node -v" or "npm -v" everything work fine.
In my PATH i have " C:\Program Files\nodejs" Not sure if that is all what I need?
Thanks in advance if someone can help me with this Problem.

I am trying to run Python in my command prompt, but when I tried it tells me python is not recognised as an internal or external command, operable program or batch file
First of all, if you didn't installed python yet, install it! https://www.ics.uci.edu/~pattis/common/handouts/pythoneclipsejava/python.html
to run a program from inside the terminal (both in Windows and Linux) it need to be in the environment PATH variable - this way the terminal knows where the actual exe/elf is.
For example, if you installed the python in C:\Python37\python.exe, the PATH should contain that path.
Please read this article which explains how to add Python to the Windows PATH - https://geek-university.com/python/add-python-to-the-windows-path/

https://raw.github.com/AmazonEMR/bootstrap.actions/master/node/install-node-bin-x86.sh
That simply just. doesn't. work.
downloads that file. Add:
node --version
At end of it.
"On the master instance (i-d6c6a28b), bootstrap action 1 returned a non-zero return code"
The script works.
Adding the
node --version
Doesn't work because the path to node executable was appended as environment variable for your bash. This does not take effect until next time you sign in.
What was chocking for me was that the example from AWS was bad.
https://github.com/AmazonEMR/sample.apps/blob/master/node/sample-mapper.js
Some how
process.stderr.write(err);
doesn't work.
Edit- Try running that install-node-bin-x86.sh line by line through ssh. It will all run fine. Node --version still doesn't work. BUT. log out the SSH session and connect again. Then do 'Node --version' it will work.

I need to put a startup script to my CentOS6 server.
I see that I need a script that contains start-stop cases.
But I have a problem to make it and neither how to put this script to startup.
Anyone can say me how can I add it?
The script must run a simply command that run a jar file:
java -jar FileName.jar
The simplest way would be to add your command to the file
/etc/rc.d/rc.local
Commands in the above file are run at startup (as root). Note that if you do this, your command will NOT respond to the usual service start/ stop commands.
