On OS X VMs, the installation directory is /opt/bitnami and OS X VM users can click the “Open Terminal” button to run commands. Learn more about the Bitnami stack environment and about OS X VMs.

    • Approach A (Bitnami installations using system packages):

        $ cd installdir/discourse
        $ RAILS_ENV=production bundle exec rails c
    • Approach B (Self-contained Bitnami installations):

        $ cd installdir/apps/discourse/htdocs/
        $ sudo RAILS_ENV=production bundle exec rails c

    A new prompt should appear, as shown below:

  • At the prompt, run the following commands to change the email address of the default user account to a new email address. Replace the EMAIL_ADDRESS placeholder in the commands below with your desired email address:

      u = User.find_by_username("user") = "YOUR_NEW_EMAIL_ADDRESS"
