Configuring Remote O&M for an MRS Cluster

Enabling Remote Node O&M Authorization for an MRS Cluster

This authorization will allow O&M personnel to temporarily access your cluster nodes before the expiration time. You can also manually cancel the authorization in advance.

Cancel the authorization immediately after the issue is resolved to prevent security risks from prolonged access.

1. Log in to the MRS console.
2. In the navigation pane of the MRS console, choose Active Clusters, locate a running cluster, and click its name to switch to the cluster details page.
3. In the upper right corner of the page, click O&M, choose Authorize for Cluster Nodes, and select the deadline for the Huawei Cloud support engineers to access the local host. Before the deadline, the support personnel have the temporary permission to access the local host.
4. Select the check box to confirm authorization and click OK.
5. After the fault is rectified, click O&M in the upper right corner of the page and choose Deauthorize for Cluster Nodes to retrieve the access permission granted to the Huawei Cloud support engineers.

   Verify that the authorization has been successfully canceled on the Operation Logs page of the MRS console.

Configuring Remote O&M Log Sharing for an MRS Cluster

Log sharing allows you to share cluster logs generated within a specified time range with technical support personnel to analyze issues without directly accessing the cluster. This method requires no cluster access authorization, ensuring high security.
