• [Mistake] Semi-colon is confusing, I think it should be #
  
• [Mistake] The file name mentioned here (extra) was not in my folder. The file name was httpd.
  
• [Lacking clarity] here serverAlias and site name should be suggested to change it your site name
  
• [Missing] The server should be restarted after completing the all the steps.
