Failed to Log In to MRS Manager After the Python Upgrade

Issue

Failed to log in to MRS Manager after Python is upgraded.

Symptom

After Python is upgraded, MRS Manager fails to be accessed using the admin account and the correct password.

Cause Analysis

When upgrading Python to Python 3.x, the user modifies the file directory permission of openssl. As a result, the LdapServer service cannot be started, causing a login authentication failure.

Procedure

  1. Log in to the Master node in the cluster as user root.
  2. Run the chmod 755 /usr/bin/openssl command to modify the file directory permission of /usr/bin/openssl to 755.
  3. Run the su omm command to switch to user omm.
  4. Run the openssl command to check whether the openssl mode can be entered.

    If it can be entered, the permission has been modified successfully. If it cannot be entered, the permission fails to be modified.

    If the permission fails to be modified, check whether the command is correct or contact O&M personnel.

  5. After the permission is modified, the LdapServer service will be restarted. After the LdapServer service is restarted, log in to MRS Manager again.
