I am new for Nodejs. I have developed an application using Expressjs. Now I want to deploy my app to the server and I already bought a server from digitalocean.
I don't have any idea that how to deploy my app via PM2.
Please help..
if you have installed nodejs and pm2 on your server. you just need to run pm2 with your express js application instance.
pm2 start bin/www
You can find your express js application instance in the package.json file. see in the screenshot below.
after that, you can run the command to check the running instance of the application.
pm2 ls
After you install nodejs to your server, first you need to install pm2 globally via npm:
sudo npm install pm2 -g
Then, just run the start command:
pm2 start "/path/app.js"
Thats it. You can see the project with: pm2 status
For more pm2 code I suggest you to take a look at https://www.npmjs.com/package/pm2
See directly the PM2 deployment page : http://pm2.keymetrics.io/docs/usage/deployment/
You just set the configuration of your server host,user,git etc... and pm2 will deploy it remotly automatically

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'm deploying my node express project with iis. pm2 don't restart after then server rebooting. can I npm start or pm2 start on webconfig file? what should I do?
when you deploy your project use at the end
pm2 save
pm2 startup
based on documentation
pm2 Save
Once you started all the applications you want to manage, you have to save the list you wanna respawn at machine reboot
Pm2 Startup
PM2 can generate startup scripts and configure them in order to keep your process list intact across expected or unexpected machine restarts
to run the node js application after the user logged out you could try to use Forever and or install forever-win using npm -g install forever-win and do then forever start app.js.
I want to keep my node server alive. Therefore I use pm2 but if I try to start my server with
pm2 start index.js
I get the message:
pm2: command not found
So, I wanted to ask how to use local pm2 in node_modules directory without installing pm2 globally.
Do I have to register pm2 in my index.js?
Can anyone provide some information about the command to start a server via pm2 which is locally installed?
Actually you can install it as a local project dependency and then run it directly with the path inside node_modules: node ./node_modules/pm2/bin/pm2 start
That way you can use it in a npm script for example.
I use this for a project that needs to run offline, bundling everything in the CI and running it locally then.
However as of lately I get some problems with the deamon starting under Windows that way. Not yet sure if it is a Windows problem or a problem with starting pm2 this way (as the globally installed version still works properly).
Try,npx pm2 start index.js. Read this article to learn about npx
If you are on AWS EC2 instance you can run the command from this path:
C:\Users\Administrator\AppData\Roaming\npm\pm2 start C:\project\app.js
In my case pm2 was installed but the err was pm2 npt found
so i ran pm2 command from that path and i worked
If you use npm, simply write in your package.json / "scripts":
"pm2": "npx pm2 start index.js -i max"
then run the script with npm run pm2
it will start your index.js with max available cluster workers
I know I can run Node.js on server with command line node app.js.
But when I am out of control server, the session will be close and end my command. I don't know how to make a service run Node.js 24/7 like another in Server.
I follow this post, but I'm not using express.
run it using forever , it helps the server to restart whenever the node server get crashed. https://www.npmjs.com/package/forever
You can make it happen by many ways.
You can append & in the command line to make the node server run in background.
node app.js > stdout.txt > stderr.txt &
Via process manager pm2, It gives more features, you can monitor all the processes pm2 monit, auto restart, etc
npm install pm2 -g
pm2 start app.js
or, using following npm packages
Nodemon - nodemon app.js
Forever - forever start app.js.
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
