Installing an Agent

Installation Precautions

• For details about the OSs supported by the agent, see Supported OSs.

• Ensure the outbound rule of your security group allows access to the port 10190 on the 100.125.0.0/16 network segment. (This is the default setting.)

• If any third-party security software has been installed on your server, the HSS agent may fail to be installed. In this case, disable or uninstall the software before installing the agent.
• The available capacity of the disk where the agent is installed must be greater than 300 MB. Otherwise, the agent installation may fail.
• After the installation, it takes 5 to 10 minutes to update the agent status. You can check it on the "Servers" tab of the "Asset Management > Servers & Quota" page.
