Managing Agents on Independent Nodes

Prerequisites

The agent of a node is online.

Upgrading the Agent on an Independent Node

HSS is periodically updated to improve its capabilities. You are advised to upgrade the agent to the latest version in a timely manner.

If the agent has not been upgraded for more than six months, HSS will automatically upgrade it to the latest version. In the latest version, the known issues in earlier versions are fixed, and the threat detection and defense capabilities are enhanced to improve overall security. The upgrade is performed by HSS in the time window from 22:00 to 06:00 the next day. It does not affect your services.

1. Log in to the HSS console.
2. Click in the upper left corner and select a region or project.
3. In the navigation pane, choose Installation & Configuration > Container Install & Config.
4. Click the Non-cluster Node tab.
5. Upgrade the agent using either of the following methods:
   • Automatic upgrade

     In the upper right corner of the node list, click to enable automatic upgrade. After this function is enabled, HSS automatically upgrades all agents to the latest version between 00:00 and 06:00 every day. You can view the agent version of a node after 06:00 the next day to check whether the upgrade is successful.

   • Manual upgrade
     1. In the Operation column of a cluster, click Upgrade Agent.

        To upgrade the agent on CCE clusters in batches, select all target nodes and click Upgrade Agent.

     2. Confirm the upgrade information and click OK.

        Wait for 5 to 10 minutes. If the agent version of the target node is the latest, the upgrade is successful.

Uninstalling the Agent from an Independent Node

Uninstall the HSS agent if you no longer need it. This section describes how to uninstall an online agent. If the agent status is offline, perform the operations in Manually Uninstalling the Agent from a Server.

2. Click in the upper left corner and select a region or project.
3. In the navigation pane, choose Installation & Configuration > Container Install & Config.

5. In the Operation column of a node, click Uninstall Agent.

   To uninstall the agent from nodes in batches, select all target nodes and click Uninstall Agent.
