Changing the OS User Password Validity Period

Scenario

By default, the password validity period of an OS user is 90 days. This topic describes how to change the validity period.

You are advised to periodically change a user's login password of the cluster node operating system to improve system O&M security.

Procedure

  1. Log in to the node where you want to change the password validity period of the OS user password as the root user.
  2. Change the OS user password validity period.

    • Legacy users

      Run the following command to change the password validity period:

      chage -MValidity period (days) user_name

      • Validity period (days): how many days the password is valid since its creation. If this parameter is set to 99999, the password never expires. Set this parameter based on the site requirements.
      • user_name: OS user whose validity period you want to change, for example, ommdba.
      • You are advised to set this parameter based on service demands and periodically change the user password.
    • New users

      Run the following command to edit the file and change the value of PASS_MAX_DAYS, which indicates the password validity period, in days. If the value is changed to 99999, the password never expires.

      vi /etc/login.defs
