3. Complete the script execution information. Input parameters are preset in common scripts and cannot be modified. Set Executed By and Timeout Interval. The default executor is user root and default timeout interval is 300 seconds.
   Script parameters can be manually entered or selected from the parameter repository. (Disk clearing is not supported currently.) If you manually enter a parameter value, you need to select the region where the parameter is located, parameter name, and parameter association mode from Creating a Parameter.
