To start sailsjs in production mode you append --prod.

Run: node app.js --prod

I\'m using PM2 and a simple json file for settings,

Answer 1

Here is my configuration file for PM2 and I have running multiple service under PM2 as one of them below, apps.json

{
  "apps": [
    {
      "name"       : "TEST_APP",
      "script"     : "./app.js",
      "cwd"        : "/Users/username/app",
      "merge_logs" : true,
      "out_file"   : "logs/pm2-out.log",
      "error_file" : "logs/pm2-err.log",
      "instances"  : 3,
      "exec_mode"  : "cluster",
      "env"        : {
                        "NODE_ENV": "dev",
                        "PORT": "9999"
                     }, 
      "env_production": {
                        "NODE_ENV": "production",
                        "PORT": 9998
                     }  
    }
  ]
}

Then simply run the following command to run your service,

$ pm2 start apps.json --env production

You can include other parameters as mentioned in the PM2 docs here. Hope this helps.
