Remote connection to MySQL is slow. Sometimes it takes 4-20 seconds to remotely connect to MySQL. The local connection to MySQL is normal. The main cause of this problem is that the reverse DNS resolution is enabled for the MySQL instance installed by default, in my. INI (in Windows) or my. add the skip-name-resolve statement to the [mysqld] of the CNF (Unix or Linux) file and save it.

Start -- run -- cmd -- net stop MySQL -- Net start MySQL -- Haha, success

Path of my. ini: D: \ Program Files \ mysql \ MySQL Server 5.0 \ My. ini

It turned out to be a problem with MySQL. After this operation, the host name cannot be used in the MySQL authorization table, but only the IP address can be used.
