How to run nuxtjs under pm2?

To run a Nuxt.js application under PM2 (a popular process manager for Node.js applications), follow these steps:

1. Ensure Node.js and PM2 are installed

First, verify that Node.js is installed on your server. After installation, use npm to install PM2 with the following command:

bash
npm install -g pm2

2. Set up your Nuxt.js application

Confirm your Nuxt.js application is properly configured and running locally. If starting from scratch, create a new project using the create-nuxt-app command:

bash
npx create-nuxt-app <project-name>

For existing projects, ensure all dependencies are installed:

bash
npm install

3. Adjust Nuxt.js configuration

To enable PM2 to manage the application, modify nuxt.config.js to listen on all IP addresses. Add the following configuration:

javascript
export default {
  server: {
    host: '0.0.0.0' // Default is localhost
  }
}

4. Create the PM2 configuration file

In your project root, create ecosystem.config.js to define startup parameters. A basic configuration is:

javascript
module.exports = {
  apps: [
    {
      name: 'NuxtAppName',
      exec_mode: 'cluster',
      instances: 'max', // Or any number of instances
      script: './node_modules/nuxt/bin/nuxt.js',
      args: 'start'
    }
  ]
}

This configuration specifies the application runs in cluster mode using Nuxt's startup script.

5. Launch your Nuxt.js application with PM2

With everything ready, start the application using:

bash
pm2 start ecosystem.config.js

6. Verify application status

Check the status with:

bash
pm2 status

This displays the status of all applications managed by PM2.

7. Configure logging and monitoring

PM2 provides robust logging and monitoring features. View logs using:

bash
pm2 logs

Or use the monitoring tool:

bash
pm2 monit

Following these steps, your Nuxt.js application should run successfully under PM2, ensuring stability and reliability in production environments. Always test all configurations in a local or development environment before deployment.
