6.2.3. Selecting Password Options
By default, the installation scripts generate random passwords for configured services. For example, these passwords include the password that the broker and node both use to authenticate with the ActiveMQ service, as well as the password for the test OpenShift user account. If you are not deploying a production instance, you can supply the
no_scramble parameter set to true to have default, insecure passwords used across the deployment.
You can set any password parameter manually with a unique password, which automatically overrides generating a random password for that parameter. When supplying a unique password, use alphanumeric characters as other characters may cause syntax errors; if non-alphanumeric characters are required, update them separately after the installation completes. For multi-host deployments, set unique passwords in parameters consistently across hosts for any services you are installing.
The scripts return a list of all passwords, whether randomly generated or manually set, after the installation is completed. The following table describes the available user name and password parameters for configured services, including the default user name values and related
install_component options:
| User Name Parameter | Password Parameter | Description |
|---|---|---|
mcollective_user
Default:
mcollective
| mcollective_password | These credentials are shared and must be the same between all broker and nodes for communicating over the mcollective topic channels in ActiveMQ. They must be specified and shared between separate ActiveMQ and broker hosts. These parameters are used by the install_component options broker and node. |
mongodb_broker_user
Default:
openshift
| mongodb_broker_password | These credentials are used by the broker and its MongoDB plug-in to connect to the MongoDB datastore. They must be specified and shared between separate MongoDB and broker hosts, as well as between any replicated MongoDB hosts. These parameters are used by the install_component options datastore and broker. |
|
Not available.
| mongodb_key
|
This key is shared and must be the same between any replicated MongoDB hosts. This parameter is used by the
install_component option datastore.
|
mongodb_admin_user
Default:
admin
| mongodb_admin_password | The credentials for this administrative user created in the MongoDB datastore are not used by OpenShift Enterprise, but an administrative user must be added to MongoDB so it can enforce authentication. These parameters are used by the install_component option datastore. |
openshift_user1
Default:
demo
| openshift_password1 | These credentials are created in the /etc/openshift/htpasswd file for the test OpenShift Enterprise user account. This test user can be removed after the installation is completed. These parameters are used by the install_component option broker. |
|
Not available.
Default:
amq
| activemq_amq_user_password | The password set for the ActiveMQ amq user is required by replicated ActiveMQ hosts to communicate with one another. The amq user is enabled only if replicated hosts are specified using the activemq_replicants parameter. If set, ensure the password is the same between all ActiveMQ hosts. These parameters are used by the install_component option activemq. |
For example, the following command runs the
openshift.sh script and sets unique passwords for various configured services, using default values for all unspecified parameters:
