Hi yichen,  
  
It's not recommended to place Greengrass in your home folder. The preferred location is /greengrass.  
If you're going to move the location you need to change the cert locations in config.json.  
Use your favorite editor to modify /home/yichen/greengrass/config/config.json

Hi yichen,  
  
The portion of the developer guide that covers this is: https://docs.aws.amazon.com/greengrass/latest/developerguide/gg-core.html#config-json  
Look under the crypto section:  
"Must be a file URI of the form: file:///absolute/path/to/file. "  
  
Thanks,
