Persist environment variable for a Rails app on Digital Ocean

问题

How can I persist environment variables for my Rails app hosted on Digital Ocean?

Locally I run a bash script with commands like, export SERVICE_USERNAME='somekey'.

But when I try to manually run export SERVICE_USERNAME='somekey', while ssh-ing onto the Ubuntu server, they only last for the session... which is not helpful for my app.

How can I persist environment variables on Digital Ocean? Is there a simple way?

回答1:

You can either set your environment variables to the user (in the ~/.profile or ~./pam_environment files of the user) or system wide (in the /etc/environment file)

You can find more info on this Ubuntu documentation.

EDIT;

You could have your script to do this:

sudo echo 'export SERVICE_USERNAME="somekey"' >> /etc/environment
