What Should I Do If the Password Cannot Be Reset After I Use a Private Linux Image to Create a FlexusL Instance or Change the OS of an Existing FlexusL Instance and I Know the Initial Password of the Private Image?

Symptom

After I use a private Linux image to create a FlexusL instance or change the OS of an existing instance, I cannot log in to the server in the instance by resetting the password. If the private image is created from a server on another cloud platform or downloaded from a third party, the image may not have the password reset plug-in installed, so the password reset function is unavailable.

• If you know the password for logging in to the server created from the private image or whose OS is changed using the private image, install the plug-in by referring to the content in this section. After the plug-in is installed, you can reset the password.
• If you forgot the server login password, see What Should I Do If the Password Cannot Be Reset After I Use a Private Linux Image to Create a FlexusL Instance or Change the OS of an Existing FlexusL Instance and I Forgot the Initial Password of the Private Image? After the plug-in is installed, you can reset the password.

Procedure

1. Log in to the FlexusL instance server 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 command output is similar to that shown in Figure 1.

   • If yes, the plug-in has been installed. No further actions are required.
   • If no, the plug-in has not been installed. Go to the next step.
3. Obtain the one-click password reset plug-in CloudResetPwdAgent.zip and verify its integrity (Linux).

   There is no special requirement for the directory where the plug-in should be stored.

4. Decompress CloudResetPwdAgent.zip.

   There is no special requirement for the directory where the CloudResetPwdAgent.zip should be decompressed.

   unzip -o -d Decompressed directory CloudResetPwdAgent.zip

   Example:

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

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

5. Install the password reset plugin.
   1. Open the CloudResetPwdAgent.Linux file.

      cd {Plug-in decompressed directory}/CloudResetPwdAgent/CloudResetPwdAgent.Linux

      Example:

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

      cd /home/linux/test/CloudResetPwdAgent/CloudResetPwdAgent.Linux

   2. Grant the execute permission to the setup.sh file.

      chmod +x setup.sh

   3. 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.

      NOTE:

      If the installation failed, check whether the installation environment meets requirements and try to install the plug-in again.

6. Modify file permissions for the password reset plug-in.

   chmod 700 /CloudrResetPwdAgent/bin/cloudResetPwdAgent.script

   chmod 700 /CloudrResetPwdAgent/bin/wrapper

   chmod 600 /CloudrResetPwdAgent/lib/*

   After the preceding operations are complete, restart the FlexusL instance on the console and then you can reset the password. For more information, see Resetting the Password of a FlexusL Instance.
