A perl script, used to send remote MySQL commands, perlmysql

Below is one of the basic scripts to write some scripts that simplify management operations.

For a user who has never used a perl script, it is still difficult to directly use the code.

This script is used to send remote MySQL commands and receive results. The function is simple and will be improved later.
