Changing the Password for the OMS Kerberos Administrator
Scenario
It is recommended that the administrator periodically change the password of OMS Kerberos administrator kadmin to improve the system O&M security.
If the user password is changed, the Kerberos administrator password is changed as well.
Procedure
- Log in to any management node in the cluster as user omm.
- Run the following command to go to the related directory:
cd ${BIGDATA_HOME}/om-server/om/meta-0.0.1-SNAPSHOT/kerberos/scripts
- Run the following command to set environment variables:
source component_env
- Run the following command to change the password for kadmin/admin. This operation takes effect for all servers. Keep the password secure because it cannot be retrieved once lost.
kpasswd kadmin/admin
Enter the password (default password: Admin@123) and set a new password. The new password must meet the following complexity requirements:
- Contains at least 8 characters.
- Contains at least four types of the following: uppercase letters, lowercase letters, numbers, and special characters (~`!?,.;-_'(){}[]/<>@#$%^&*+|\=).
- Cannot be the same as the username or the username spelled backwards.
- Cannot be a common easily-cracked password, for example, Admin@12345.
- Cannot be the same as the password used in the last N times. N indicates the value of Repetition Rule in Configuring Password Policies.
