The situation is, I'm using Socket.io for a chat application using node js (AWS EC2 Linux).
For other applications, PM2 is working fine since I use Express with Node js.
PM2 does not work with Socket.io because here I'm using http to listen.
var http = require('http');
So I have to go with Forever.
But forever does not work with crontab in linux since I want the app started on system reboot.
I tried forever-service to start the app during reboot. But I get this error
forever-service must run as root.
So I tried with sudo forever-service install test
Then it throws sudo: forever-service: command not found
I want my Chat application to auto restart on system reboot. Please help.

I am trying to set up a node.js server. On my Mac, I can start and stop the app in terminal like:
start=
node app.js
stop=
CTR-c
I also have the same node setup on my linux server website.
I try to do the same start and stop in the terminal the same way on the linux server but I can't seem to stop it with CTR-c even though it looks like it did work.
The app keeps running.
My goal is to to be able to make edits / mods to the webserver node app. I think we have to stop and start to update the changes - but it does not seem to be working.
I know a bit about nodemon - but do not know if it should be used on live production servers?
Q: How do I make changes to the linux server app and get them to show up like they do in MacOS?
The task is to write a utility for deploying the NodeJS application. Requirement is to run the utility from any computer. The problem is that pm2 does not take in mind that I have switched the working directory to the server:
process.chdir ('SERVER');
process.cwd (); // SERVER
But commands run on my workstation. Share furioku, how to let pm2 know that commands need to be run on the server?
I am in need to manage my node server without entering into server console. I have tried using forever, nodemon and pm2 npms. Whenever, I need to start or stop the node application, I need to connect the server via terminal. I want to avoid that and willing to see the possibility if that can be managed through any web interface or any browser plugin/extension.
Already tried forever, nodemon and pm2
You can use npm pm2-gui install it by this command npm i pm2-gui
See the docs and guides from here https://www.npmjs.com/package/pm2-gui
I started looking for some GUI and Web interface of PM2. Tried several npms but "mc-pm2-web" worked really good for me.
I am using Node via NVM and my node version was v10.15.3. Installed this https://www.npmjs.com/package/mc-pm2-web and it was straight forward what I was actually looking for.
Here's are the step if anybody wants to install and configure "mc-pm2-web" in AWS EC2.
I am using Amazon Linux
I am using NVM and running v10.15.3
Already had NGINX & PHP-FPM running on server using port 9000
pm2 already installed
Visit this link:
https://www.npmjs.com/package/mc-pm2-web
npm install -g pm2-web
pm2-web
If you encountered any error then you may check your config.json file. In my case the config file path was:
/home/ec2-user/.nvm/versions/node/v10.15.3/bin/pm2-web/config.json
I made following changes in config file to make it working:
Port from 9000 to 9010 because 9000 was being used by PHP-FPM
Changed the host name from "localhost" to "my-domain" which was already hosted in NGINX
Enabled authentication and set the Username and Password for making it secure
Allowed 9010 port from AWS EC2 firewall / security group of that instance
Added pm2-web in pm2 by executing "pm2 start pm2-web" command
I have developed a simple node.js application and I am trying to publish it on AWS Lightsail. I followed the instructions on this page: https://medium.com/#sharmasha2nk/aws-lightsail-bitnami-nodejs-letsencrypt-cf653573b8a1
I am connecting to Bitnami using the SHH console provided. After I start the app with node index.js command the app is up and running until I close the SHH console. As soon as I close it the application stops and “Service Unavailable” error is being displayed. How can I keep my app running on AWS even if my PC is shot down and the SHH console is closed?
I have tried restarting the apache server and AWS Lightsail instance. Neither of them helped.
httpd-app.conf file content:
ProxyPass / http://127.0.0.1:3000/
ProxyPassReverse / http://127.0.0.1:3000/
httpd-prefix.conf file content:
Include "/opt/bitnami/apps/emsnotes/conf/httpd-app.conf"
Thanks.
I would recommend you pm2
Here's how to do it quickly:
install pm2 globally using sudo npm i -g pm2
navigate to the location of your index.js via ssh
run pm2 start index.js
This will keep node running even when you disconnect the ssh session or shutdown your development computer. The process will keep running on your server in the background. This is used for running node apps in production on a server.
You can read all about it here in its documentation.
I hope I could help you, please let me know if you have any question.

I had a look at the article and frankly i see nowhere that he talk about keeping the server up and running.
Basically he is using the Bitnami Node.js stack and if you look at the docs you will see that Bitnami use Forever.js to keep the apps running on their instance, Forever is a CLI tool to monitor and keep a Node instance running in the background.
Check the docs here : https://docs.bitnami.com/general/infrastructure/nodejs/administration/start-express-server/
Here is the Git for Forever, so can read more on it: https://github.com/foreverjs/forever
I have node application hosted in amazon ec2.
I used nginx to point it in my domain.
It runs perfectly when i use npm start to run the application.
But when i use pm2, it doesnt work.
pm2 list command shows that the app is running.
But url doesn't work. Even when i again run npm start app gets started that clearly states that the port is free. So pm2 is not actually running anything on that port. But pm2 says app is online.
I was running the wrong file from pm2. As it was express project, so i had to run bin/www
So the following command solve the issue:
pm2 start bin/www
Answered it here as well:
