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:
- EIP-based Access: 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.
- Access Using a Windows ECS: Independent ECSs need to be created and configured.
- Creating an SSH Channel for Connecting to an MRS Cluster and Configuring the Browser: Use this method when the user and the MRS cluster are on different networks.
Access the web UIs. For details, see Table 1.

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.

**Table 1** Web UI addresses of open-source components¶
Cluster Type	Web UI Type	Web UI Address
All Types	Manager	Applicable to clusters of all versions https://Floating IP address of Manager:28443/web Note Ensure that the local host can communicate with the MRS cluster. 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. For MRS 1.8.0 or later to MRS 2.1.0 https://<EIP>:9022/mrsmanager?locale=en-us For details, see Accessing MRS Manager MRS 2.1.0 or Earlier). For MRS 3.x or later, see Accessing FusionInsight Manager (MRS 3.x or Later).
