mysql_config_editor介绍
mysql_config_editor是MySQL自带的一款用于安全加密登录的工具，可以在一些场合避免使用密码明文，例如，写shell脚本时，不用在为在脚本里面写入明文密码纠结了；也可以用于管理多台MySQL实例。另外，像如果使用mysql命令登录数据库，可以避免每次都要输入一堆参数。简单方便。
官方文档介绍如下：
The mysql_config_editor utility enables you to store authentication credentials in an obfuscated login path file named .mylogin.cnf. The file location is the %APPDATA%\MySQL directory on Windows and the current user's home directory on non-Windows systems. The file can be read later by MySQL client programs to obtain authentication credentials for connecting to MySQL Server.
