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:

  1. Select an access method.

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

  2. Access the web UIs. For details, see Table 1.

Web UIs

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.

MRS Manager

  • Method 1: Clusters of all versions

    https://Floating IP address of Manager:28443/web

    NOTE:
    1. Ensure that the local host can communicate with the MRS cluster.
    2. Log in to the Master2 node remotely, and run the ifconfig command. In the command output, eth0:wsom indicates the floating IP address of MRS Manager. Record the value of inet. If the floating IP address of MRS Manager cannot be queried on the Master2 node, switch to the Master1 node to query and record the floating IP address. If there is only one Master node, query and record the cluster manager IP address of the Master node.
  • Method 2: Earlier than MRS 3.x

    https://<EIP>:9022/mrsmanager?locale=en-us

    For details, see Accessing MRS Manager (MRS 2.x or Earlier).
