Setting environment variables

To avoid having to provide credentials every time you run an OpenStack command, create a file containing environment variables that can be loaded at any time. The following commands will create a file named adminrc containing environment variables for the admin user:

    # cat >> ~/adminrc <<EOF
     export OS_PROJECT_DOMAIN_NAME=default
     export OS_USER_DOMAIN_NAME=default
     export OS_PROJECT_NAME=admin
     export OS_USERNAME=admin
     export OS_PASSWORD=openstack
     export OS_AUTH_URL=http://controller01:35357/v3
     export OS_IDENTITY_API_VERSION=3
     EOF

The following commands will create a file named demorc containing environment variables for the demo user:

    # cat >> ~/demorc <<EOF
     export OS_PROJECT_DOMAIN_NAME=default
     export OS_USER_DOMAIN_NAME=default
     export OS_PROJECT_NAME=demo
     export OS_USERNAME=demo
     export OS_PASSWORD=demo
     export OS_AUTH_URL=http://controller01:35357/v3
     export OS_IDENTITY_API_VERSION=3
     EOF

Use the source command to load the environment variables from the file:

    # source ~/adminrc

The demo user doesn't exist yet but will be created in the following sections.
