Basically i'm a linux user. For the first time i'm running my node.js application in windows machine. I want to run my application as background process.
So installed forever globally npm install forever -g. Now i tried to run my node application using forever start app.js.
I am receiving error as forever is not reconised as internal or external command.
I tried setting the ENV varibales pointing to bin folder of forever. But still im getting the error.

I'm new to PM2 and nodejs, I'm trying to learn node by following simple sample that creates a server that displays 'Hello World' from the browser. Please note that I'm running node on QNAP NAS. I have successfully installed nodejs, npm, and pm2. when I run app.js via node app.js, it works and I see the message using the port specified.
but when I run via pm2 start app.js, I got this
Then after a few seconds I got status = errored
when I look at the log I got this.
I tried searching in google but the result were pointing to old version of node which I don't
Node itself has to be built with inspector. You can try to install LTS version of node.
Alternatively, you can try installing node-inspector with npm i node-inspector --save
I created folder for project, copy package.json and run npm install, build locally nestjs project and copy dist into server. Then ran in console node dist/main.js. For testing I used a base NestJS project (nest new ...) which only return "Hello word" on 3000 port.
Server work fine, but after close of console will stop.
I think problem on VPS (Ubuntu) settings or may be need to add some parameters to NestJS.
Why it not work constantly?
Thanks in advance for any advice.
I resolved problem with npm forever - https://www.npmjs.com/package/forever
install it globally - npm install forever -g
then got to project dir and run - forever start dist/main.js
Seems all work fine.
My environment is ubuntu 16.04 with npm 5.0.0 and node 8.0.0 installed. I created an express application and started it with nohup npm start & in the application root directory. However, a couple of minutes later the app became unreachable and the process was lost. I tried restarting several time but the process always automatically exits. How can I start a long-running nodejs app?
Use pm2 daemon for setting Up a Node.js Application for Production on Ubuntu 16.04
Follow commands
sudo npm install -g pm2
pm2 start server.js //Yor main node server.js
pm2 stop server //no need of giving .js , .js only required at start of process
pm2 restart server //for any changes are done to restart

I am new to NodeJS. I tried using my node js application in my local machine, with installing forever module, script runs continuously
But when I deploy my application in VPS(Godaddy). Node application runs fine. I tried installing forever inorder to run my script continuously, with command
npm install forever -g.
It installs the module but when trying to run it with command
forever start app.js
says forever command not found.
Can anyone guide me what am I doing wrong? Any help will be appreciated.
You should check with npm list -g if the module is listed.
Other way to check it is to go to a bash console and type ls /usr/local/lib/node_modules | grep forever and check if the module is there.
If it's not there, something went wrong installing the module. Install it again with sudo npm install -g forever.
Check with printenv | egrep -o "(.*node*) in the bash console and see if you have "NODE_PATH=/opt/lib/node_modules".
If not export NODE_PATH=/opt/lib/node_modules int the console and try again the forever command forever start app.js.
I installed Ghost Blog with a subdomain (http://blog.example.com) on Ubuntu 14.04 LTS behind Apache 2.4.7 as a Proxy.
Ghost is located in var/www/html/ghost and can be started temporarily with sudo npm start, which works fine.
However, when I want to permanently deploy Ghost using NPM forever, which I installed globally following the official Ghost guide, I get the following error message:
info: Forever processing file: index.js
error: Cannot start forever
error: script /home/myuser/index.js does not exist.
Simply copying index.js to the predefined npm forever root location does not solve the problem, as the Ghost application is not located there. I also tried sudo NODE_ENV=production forever start var/www/html/ghost/index.js without success.
I always get a 503 Error - Service Unavailable.
How do I tell NPM forever to look for the file in var/www/html/ghost/index.js?
It sounds like you are not giving forever the correct file. That is what this error is saying (error: script /home/myuser/index.js does not exist.). There is no index.js in your /home/myuser directory.
So, to start Ghost with forever first cd to the ghost directory:
cd /var/www/html/ghost
and then do the forever start:
sudo NODE_ENV=production forever start index.js
Should be good to go once you do that
