Web UIs of Open Source Components
=================================

Scenario
--------

Web UIs of different components are created and hosted on the Master or Core nodes in the MRS cluster by default. You can view information about the components on these web UIs.

Procedure for accessing the web UIs of open-source component:

#. Select an access method.

   MRS provides the following methods for accessing the web UIs of open-source components:

   -  :ref:`EIP-based Access <mrs_01_0646>`: This method is recommended because it is easy to bind an EIP to a cluster. Versions later than MRS 1.7.2 supports this method.
   -  :ref:`Access Using a Windows ECS <mrs_01_0647>`: Independent ECSs need to be created and configured.
   -  :ref:`Creating an SSH Channel for Connecting to an MRS Cluster and Configuring the Browser <mrs_01_0363>`: Use this method when the user and the MRS cluster are on different networks.

#. Access the web UIs. For details, see :ref:`Table 1 <mrs_01_0362__td1aa324b6c0543c786768b6ea4e7d46d>`.

Web UIs
-------

.. note::

   For clusters with Kerberos authentication enabled, user **admin** does not have the management permission on each component. To access the web UI of each component, create a user who has the management permission on the corresponding component.
