installer creates 'ispconfig database user' based on the hostname, creating dependencies
If you have a multi server setup, each server will get an ispconfig mysql user entry based on their hostname. This only works if the database server has /etc/hosts entries matching the ipnumner and hostname or if reverse dns is setup correctly.
I would suggest to add two grants in mysql per host, one based on hostname and one based on ip or only use the ip based one.
Benefits:
- it will not break when reverse dns stops working or does not match the hostname anymore.
- you can disable dns resolving by mysql daemon completely when you are looking for performance improvements
- if you don't rely on reverse dns, you don't have to maintain the /etc/hosts file of the mysql server.
