MySQL not accepting requests during http flood?

Question

MySQL

On my VDS, when there is an http flood on the machine from an attacker, mysql is so loaded with requests that it does not accept connections. How can I make nginx reject requests from all clients during an http flood, but at the same time mysql works as expected, accepting requests, and not rebooting, since in the "background" it is connected to another server, where a constant connection to the database is important?

Answer 1

Make a limit of hits by ip address. For example, pieces 5 requests per second. configured in nginx
