但是當我跑起來的時候，卻報下面的錯誤

Starting Solr 
The currently defined JAVA_HOME (/usr/local/openjdk-11) refers to a location
where java was found but jstack was not found. Continuing.
WARNING: Starting Solr as the root user is a security risk and not considered best practice. Exiting.
         Please consult the Reference Guide. To override this check, start with argument '-force'

我應該怎么辦？
