How Do I Query and Change the Password Validity Period of a User In a Cluster?

Querying the Password Validity Period

1. Log in to the node where the client is installed as the client installation user.
2. Run the following command to switch to the client directory, for example, /opt/Bigdata/client:

   cd /opt/Bigdata/client

3. Run the following command to configure environment variables:

   source bigdata_env

4. Run the following command and enter the password of user kadmin/admin to log in to the kadmin console:

   kadmin -p kadmin/admin

   Note

   The default password of user kadmin/admin is Admin@123. Change the password upon your first login or as prompted and keep the new password secure.

5. Run the following command to view the user information:

   getprinc Internal system username

   Example: getprinc user1

   kadmin:  getprinc user1
   ......
   Expiration date: [never]
   Last password change: Sun Oct 09 15:29:54 CST 2022
   Password expiration date: [never]
   ......
   
   

1. Log in to any master node in the cluster as user root.
2. Run the following command to view the password validity period (value of Password expires):

   chage -l Username

   For example, to view the password validity period of user root, run the chage -l root command. The command output is as follows:

   [root@xxx ~]#chage -l root
   Last password change                                    : Sep 12, 2021
   Password expires                                        : never
   Password inactive                                       : never
   Account expires                                         : never
   Minimum number of days between password change          : 0
   Maximum number of days between password change          : 99999
   Number of days of warning before password expires       : 7
   
   

Changing the Password Validity Period

• The password of a machine-machine user is randomly generated and never expires by default.
• The password validity period of a human-machine user can be changed by modifying the password policy on Manager.
