How do I do this mysqladmin flush-host?
This is my first time working with cpanels and Linux. I worked with windows server and I logged directly on the server with direct access to the run cmd. I am not sure where it is in the cpanel
mysqladmin flush-hosts
In order to run this yourself you would need root access to your server, which is explained in detail in our guide on standard SSH access vs root access. Please let us know if you're still experiencing any issues at all. - Jacob
