How Do I Query and Change the Password Validity Period of an Account?

Querying the Password Validity Period

Querying the password validity period of a component running user (human-machine user or machine-machine user):

  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

    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]
......

Querying the password validity period of an OS user:

  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.
