Set Linux shell environment variable

You could set the environment variable in the settings file as explained in below link.

How to set env variable

One way of setting environment variables is in your settings.js file. The following will set the env var MY_ENV_VAR: process.env.MY_ENV_VAR = "Hello World"; You can add lines like that to the top of your settings file. The other option is to set them completely outside of Node-RED in shell you are running Node-RED in. How you do that will depend on your OS and how you are running Node-RED.
