pm2从子目录开始

Question

I have a script in package.json like this. To run with npm I would just do it with npm start .

"scripts": {
    "start": "cd build && node main"
}

I am currently trying to setup a pm2 config file for this. I created a ecosystem.json file. Neither of both of the following work with pm2 ecosystem command. What am I doing it wrong?

Note that it work if i manually type cd build && pm2 start main.js in command but this is not something i want.

First configuration:

{
    "apps": [{
        "name": "my-app",
        "cwd": "build",
        "script": "main.js"
    }]
}

Second configuration

{
    "apps": [
        {
            "name": "my-app",
            "script": "npm",
            "args" : "start"
        }
    ]
}

In your code, you are giving the path incorrectly.

Use following instructions:

1. Hit pm2 ecosystem command, this will create a new file by name ecosystem.config.js

2. Remove all the code from the file and add the following code.

    module.exports = { apps : [ { name : 'API', script : 'build/main.js', } ] }; 

3. Hit pm2 start ecosystem.config.js

4. Check the logs using pm2 logs , your app will be started.

Hope this helps you.
