Installing the Agent on Linux

Updated on 2025-01-24 GMT+08:00

Scenarios

You need to install the Agent on the source server to be migrated. During the installation, you need to enter the AK/SK pair of the Huawei Cloud account you are migrating to. After the Agent is started, it automatically reports source server information to SMS. The information is used for migration only. For details, see What Information Does SMS Collect About Source Servers?

NOTE:

Before using SMS to migrate servers, you need to manually install and register the Agent on each server to be migrated. If there are more than 50 servers to migrate, you can create a server migration workflow on MgC to automate batch installation and registration of the Agent.

Prerequisites

  • You have confirmed that the source server OS is supported by SMS. Learn more about supported Linux OSs.

Procedure

  1. Sign in to the SMS console.
  2. In the navigation pane on the left, choose Agents.
  3. Select the Linux card, and in the Linux Agent area, click the icon next to Agent to copy the Agent download command. Run the command on the source server to download the Agent installation package.

  4. Copy the command next to SHA256 File and run the command on the source server. Use the hash value contained in the SHA256 file to verify the integrity of the Agent installation package. For details, see How Do I Verify the Integrity of the Agent Installation File?

  5. Decompress the Agent software package.

    tar -zxvf SMS-Agent.tar.gz

  6. Switch to the SMS-Agent directory on the source server.

    cd SMS-Agent

  7. If you need to use an HTTP/HTTPS proxy, go to 8.

    If you do not need to use an HTTP/HTTPS proxy, go to 9.

    CAUTION:
    • If your source server cannot access Huawei Cloud over the Internet, you can use a proxy server. You will need to configure the proxy server yourself.
    • In a migration over a private line or VPN, a proxy server is used for registering the source server with SMS. It is not used for data migration.

  8. (Optional) Configure the HTTP/HTTPS proxy for the Agent.

    1. Go to the config directory.
      cd SMS-Agent/agent/config
    2. Open and edit the auth.cfg file. Do not edit the auth.cfg file unless you need to use an HTTP/HTTPS proxy.
      vi auth.cfg

      The values shown here are for reference only.

      [proxy-config]
      enable = true
      proxy_addr = https://your-proxy-addr.com
      proxy_port = 3128
      proxy_user = root
      use_password = true
      NOTE:
      • enable: To use a proxy, set it to true.
      • proxy_addr: Replace your-proxy-addr with the IP address of the proxy server, not that of the target server. Use the protocol configured for the proxy. HTTPS is recommended.
      • proxy_user: Enter the username required for the proxy. If no username is required, leave it blank.
      • use_password: If a password is required for the proxy, set it to true. If no password is required, set it to false.
    3. Save the auth.cfg file and exit.
      :wq

  9. Start the Agent.

    ./startup.sh

  10. Carefully review what information will be collected by the Agent, enter y, and press Enter.

    Figure 1 Entering y

  11. Enter the AK/SK pair for the Huawei Cloud account and the SMS domain name for the region you are migrating to. You can obtain the SMS domain name on the Agents page of the SMS console, as shown in Figure 3.

    Figure 2 Entering the AK/SK pair
    Figure 3 Obtaining the SMS domain name

    If the EPS service has been enabled for the Huawei Cloud account, after you entered the AK/SK pair, the Agent will list all enterprise projects the account is allowed to access. You can select the enterprise project you would like to migrate the source server to. This enables you to isolate permissions, resources, and finance during the migration. For details, see Migrating Servers into an Enterprise Project.

    When the following information is displayed, the Agent has been started up and will automatically start reporting source server information to SMS. You can go to the Servers page on the SMS console to view the record of the source server.
