Deploying the app using PM2 in EC2

[sn17091004]

Hi,

I am following this tutorial https://medium.com/@Keithweaver_/setting-up-mern-stack-on-aws-ec2-6dc599be4737 and trying to deploy this app.

However, I am stuck in this step pm2 start server.js -- --production . It is throwing error but there is no description of error / logs.

Have anyone deployed this app to EC2 with PM2 ? Can you please help in deploying this app ?

Or is there anything wrong with this command pm2 start server.js -- --production

Thanks,

I just deployed on DigitalOcean droplet and this worked.
I reckon it should work for EC2 as well.

start:prod script under packages.json gave me some clues
"start:prod" : "cross-env NODE_ENV=production node index.js"
According to this we need to set environment as production and then run index.js

pm2 config and setup

Step 1:
cd to project folder

Step 2: Create ecosystem.config.js file for pm2
with the following config

module.exports = {
  apps : [{
    name      : 'MERN',
    script    : 'index.js',
    env: {
      NODE_ENV: 'development'
    },
    env_production : {
      NODE_ENV: 'production'
    }
  }],
};

Replace 'MERN' with your app's name so it will show in pm2 list.

Step 3: Start app's process using pm2

For production -
pm2 start --env production
For development -
pm2 start --env development

You should see following output

 App name │ id │ mode │ pid   │ status │ restart │ uptime │ cpu  │ mem       │ user │ watching │
├──────────┼────┼──────┼───────┼────────┼─────────┼────────┼──────┼───────────┼──────┼──────────┤
│ MERN     │ 0  │ fork │ 29305 │ online │ 0       │ 3m     │ 0.1% │ 93.4 MB   │ root │ disabled │

Thats it! 👍 Your app is now up and running.
Hope this helps!
Please let me know how it goes.

Some basic pm2 operations / [ replace MERN with your app name]

Stop App
pm2 stop MERN

Start App
pm2 start MERN

Monitor App
pm2 monit MERN

Delete App
pm2 delete MERN
