Manager

  • Applicable to 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.
