Step 2: Uninstalling the Agent of the Old Version

A server can install only one agent. HSS agents of the old version are incompatible with some features of the new version. You need to uninstall the agent of the old version.

Uninstallation Description

You can uninstall an old agent in either of the following ways:
  • Uninstall agents on the console in one click: On the HSS console of the old version, select multiple servers and uninstall their agents in one-click mode.
  • Uninstall the agent from the server: Log in to the target servers and run the corresponding commands to uninstall the agents. Batch uninstallation is not supported.

Uninstalling the Agent on the Console in One Click

  1. Log in to the management console.
  2. Click in the upper left corner of the page, select a region, and choose Security > Host Security Service.
  3. In the navigation pane, choose Installation & Configuration. In the upper right corner of the displayed page, click Uninstall Agent.
  4. In the displayed Uninstall Agent page, select the servers that you want to uninstall the agent.
  5. Confirm the selected servers and click OK.

    Choose Servers & Quota and click the Servers tab. If the agent status of the target server is Offline, the agent is uninstalled successfully.

Uninstalling the Agent from the Server

The commands used for uninstalling the agent are different based on the OS of the server.

  • Uninstalling the Linux agent
    1. Log in to the server whose agent you want to uninstall and run the following command to switch to user root. 
      su - root
    2. In any directory, run the following command to uninstall the agent:
      1. If the agent was installed using an .rpm package, run the rpm -e --nodeps hostguard command.
      2. If the agent was installed using a .deb package, run the dpkg -P hostguard command.
    3. If the following information is displayed, the agent is uninstalled: 
      Stopping Hostguard...

Hostguard uninstalled.
  • Uninstalling the Windows agent
    1. Log in to the server whose agent you want to uninstall.
    2. Click Start and choose Control Panel > Programs. Then select HostGuard and click Uninstall.
      • Alternatively, go to the installation directory and double-click unins000.exe.
      • If you have created a folder for storing the agent shortcut under the Start menu when installing the agent, you can also choose Start > HostGuard > Uninstall HostGuard to uninstall HostGuard.
    3. In the Uninstall HostGuard dialog box, click Yes.
    4. After the uninstallation is complete, click OK.
