MySQL skip-name-resolve skip-grant-tables

Skip-name-resolve

This statement is used to bypass DNS domain name resolution, which is faster on LAN connections, but with this command, the host in the MySQL library's user table must be changed from localhost to%, otherwise it cannot connect to the database.

Skip-grant-tables

Use this statement to skip the user table permission check and log in directly to the database when you forget your password

The latter is more dangerous
