How Do I Install HSS on MRS Cluster Nodes?

You can install Host Security Service (HSS) on your MRS cluster nodes if the OS versions of the nodes are supported by HSS agents.

Perform the following steps to install HSS:

1. Check whether the OS versions of the MRS cluster nodes are supported by HSS agents.

   To query the OS versions, perform the following operations:

   1. Log in to the MRS management console.
   2. Choose Clusters > Active Clusters, select a running cluster, and click the cluster name to access its details page.
   3. Click the Nodes tab. Click the master or core node group, and click any node in the node name list to access the cloud service basic information page.
   4. Click Basic Information, view the image in the ECS information, and confirm the EulerOS version in the image.

      For example, EulerOS_2.5_x86_64 indicates that the OS version is EulerOS 2.5 (64-bit).

   5. Check whether the OS versions of the MRS nodes are supported by HSS agents.

      For details about the OSs supported by HSS agents, see Supported OSs.

      • If yes, go to 2 to install HSS agents.
      • If no, HSS cannot be installed.
2. Purchase HSS quotas and log in to each node in the MRS cluster to install HSS agents. After the agents are installed, you can enable HSS.
   

   Ensure you have purchased HSS in your MRS cluster node region and have used the installation package or installation command in the region to install HSS agents on your nodes.
