How Do I Install HSS on MRS Cluster Nodes?

Scenario

Nodes in an MRS cluster can be managed by the Host Security Service (HSS) for risk prevention and intrusion detection. You can identify and manage information assets on MRS nodes and build a security system that defends against server attacks.

Constraints and Restrictions

HSS can be installed for MRS nodes run by OSs supported by the HSS agent.

Procedure

1. Check whether the OSs of the MRS nodes are supported by HSS agents.
   1. Log in to the MRS console.
   2. In the navigation pane on the left, choose Active Clusters. Click a cluster name to go to the cluster details page.
   3. Click the Nodes tab. Click the target node group and click any node in the list to access the basic information page of the server.

   4. On the displayed ECS page, click the Summary tab. Check the EulerOS version in the ECS Information area.

      If EulerOS_2.10_x86_64 is displayed in the image, the OS version is EulerOS 2.10 64-bit for Linux (x86).

   5. Check whether the OS version of the MRS node is supported by HSS agents.

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

      • If the OS version is supported, go to 2 to install HSS agents.
      • If it is not supported, 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.
