How to install Server Guard in the image?

Last Updated: Jan 08, 2018

Log on to the Alibaba Cloud Security Server Guard console, access the Install/Uninstall page, and install the Security Guard agent by following the instructions on that page. Verify the following content after the installation:

  1. Start the system and check if both “AliYunDun” and “AliYunDunUpdate” processes exist. For a Windows system, check if both “AliYunDun.exe” and “AliYunDunUpdate.exe” exist.

  2. Check if the version number is correct. Open the cur_version.txt file of the “AliYunDunUpdate” process, and check if it is update_00_86(windows), update_00_87(linux) or a later version.

    • For a Linux system, this file can be found in the /usr/local/aegis/aegis_update/ directory.
    • For a Windows system, this file can be found in the C:\Program Files (x86)\Alibaba\Aegis\aegis_update directory.
  3. Use the telnet command to check if you can connect to the Server Guard server from the image. For example, the following two results indicate that the server can be connected.

    1. telnet jsrv.aegis.aliyun.com 80
    2. telnet update.aegis.aliyun.com 80
