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 drive C.
• 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 CloudResetPwdAgent and CloudResetPwdUpdateAgent have been installed on the ECS.

   Start Task Manager and check whether cloudResetPwdAgent and cloudResetPwdUpdateAgent are displayed on the Services page.

   Figure 1 Checking whether the plug-in has been installed
   
   • If yes, no further action is required.
   • If no, go to 2.
2. Download and decompress the CloudResetPwdAgent installation package.
   

   The one-click password reset plug-in can be automatically updated only if an EIP is bound to the ECS.

   The download path is as follows:

   http://cn-south-1-cloud-reset-pwd.obs.cn-south-1.myhuaweicloud.com/windows/reset_pwd_agent/CloudResetPwdAgent.zip

3. Install the plug-in.
   1. Double-click setup.bat in both the CloudResetPwdAgent.Windows and CloudResetPwdUpdateAgent.Windows directories.
   2. Check whether the installation is successful in Task Manager.

      If you can find cloudResetPwdAgent and cloudResetPwdUpdateAgent in Task Manager, the installation is successful. Otherwise, the installation failed.

      

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