Installing the One-Click Password Reset Plug-In

Scenarios

You are advised to install the password reset plug-in CloudResetPwdAgent before creating a private image. In this way, you can reset the password of ECSs created from the image by a few clicks.

  • ECSs created from a public image have this plug-in installed by default.
  • For ECSs created from an external image file, install the plug-in by performing the operations in this section.

The installation of this plug-in is optional. If you want to use the one-click password resetting function on the management console, install the plug-in by following the instructions provided in this section.

Precautions

  • You can decide whether to install the CloudResetPwdAgent plug-in.
  • Not all OSs support the one-click password reset plug-in. Table 1 lists the OSs that support this plug-in.

Prerequisites

  • The ECS status is Running.
  • The ECS must have a remaining space of more than 300 MB, and data can be written to its root directory.
  • SELinux affects the password reset plug-in of Linux ECSs. You can disable it by referring to "Disabling SELinux" in Elastic Cloud Server User Guide.
  • ECSs created using a SUSE 11 SP4 image must have 4 GB or a larger memory.
  • DHCP must be enabled for the VPC used by the ECS.
  • Networks of the ECS are normal.
  • The outbound security group rule of the ECS must meet the following requirements:
    • Protocol: TCP
    • Port Range: 80
    • Remote End: 169.254.0.0/16

    If you use the default outbound security group rule, preceding requirements can be met, and the ECS can be initialized. The default outbound security group rule is as follows:

    • Protocol: All
    • Port Range: All
    • Remote End: 0.0.0.0/16

Procedure

  1. Check whether the one-click password reset plug-in has been installed on the ECS.

    1. Log in to the ECS as user root.
    2. Run the following command to check whether CloudResetPwdAgent has been installed:

      ls -lh /Cloud*

      Figure 1 Checking whether the plug-in has been installed

      Check whether the obtained information is similar to that shown in Figure 1.

      • If yes, the plug-in has been installed.
      • If no, the plug-in has not been installed. Then, install it.

  2. Download the one-click password reset plug-in CloudResetPwdAgent.zip.

    Contact the administrator to obtain the path of the OBS bucket from which the plug-in will be downloaded.

    For example, the download path is http://xxx-cloud-reset-pwd.obs.com/linux/64/reset_pwd_agent/CloudResetPwdAgent.zip.

    Run the following command to download the plug-in:

    wget http://xxx-cloud-reset-pwd.obs.com/linux/64/reset_pwd_agent/CloudResetPwdAgent.zip

  3. Run the following command to decompress CloudResetPwdAgent.zip:

    There is no special requirement for the directory that stores the decompressed CloudResetPwdAgent.zip. Use any directory.

    unzip -o -d Decompressed directory CloudResetPwdAgent.zip

    For example:

    If the plug-in is decompressed to /home/linux/test, run the following command:

    unzip -o -d /home/linux/test CloudResetPwdAgent.zip

  4. Install the one-click password reset plug-in.

    1. Run the following command to open the CloudResetPwdAgent.Linux file:

      cd CloudResetPwdAgent/CloudResetPwdAgent.Linux

    2. Run the following command to add the execute permission for the setup.sh file:

      chmod +x setup.sh

    3. Run the following command to install the plug-in:

      sudo sh setup.sh

      If "cloudResetPwdAgent install successfully." is displayed and "Failed to start service cloudResetPwdAgent" is not displayed, the installation is successful.
      • You can also check whether the plug-in has been installed using the methods provided in 1.
      • If the installation failed, check whether the installation environment meets the requirements and install the plug-in again.

  5. Modify the file permissions of the password reset plug-in.

    chmod 700 /CloudrResetPwdAgent/bin/cloudResetPwdAgent.script

    chmod 700 /CloudrResetPwdAgent/bin/wrapper

    chmod 600 /CloudrResetPwdAgent/lib/*
