Configure sudo in Debian

By default, root account is not enabled to login to Debian. As a result, a sudo authentication is needed when you add Debian Linux as a Linux Node.

Follow these steps:

  1. Log in to the Linux node and switch to root using su command.
  2. If sudo is not installed, install sudo package using the following command:

    3. apt-get install sudo

  3. Add an existing user with id=user to group=sudo:

    Example:

    adduser user sudo

  4. or create a new user with sudo

    5. adduser user

    adduser user sudo

  5. Log into the user shell, and type the following command to verify that the user is authorized:

    6. sudo -v

You have successfully configured sudo in Debian.
