Preparing the mcidas Account (Single-User Configuration)

Note: This section contains the instructions for preparing the mcidas account when installing McIDAS-X on Windows in the single-user configuration. For the multi-user configuration instructions or information about the two configuration options, return to the Configuration Options and Instructions and follow those instructions.

Each account in Windows runs a separate instance of Ubuntu^®. The single-user configuration requires two accounts in Ubuntu: the main user account (e.g., mcuser) and the mcidas account. The main user account is the account that is automatically logged in when an Ubuntu shell is started from Windows, and is the account used to run McIDAS-X. The mcidas account is created by the main user, and it is the account that is used to build and install the McIDAS-X software.

Create and configure the mcidas account

If McIDAS-X is already installed and you are simply updating to a new version, the mcidas account is already configured, and you can skip to the next step (Installing McIDAS-X on Windows).

Complete the steps below to create and configure the mcidas account under the main user in Ubuntu.

Open an Ubuntu shell and run command whoami to verify that you are logged in as the main user account (created in the previous section, e.g., mcuser).

Run the four sudo commands below to create the mcidas account and its home directory.

Type:  sudo useradd -s /bin/bash -U mcidas
Type:  sudo passwd -d mcidas                           (password expiry information changed is a normal response)
Type:  sudo mkdir -p /home/mcidas
Type:  sudo chown mcidas:mcidas /home/mcidas
