我正在尝试配置 MySQL 5.1.63，使其仅允许通过 SSL 进行远程连接。我可以确认连接通过 SSL 工作，但是我似乎无法阻止未加密的连接。
我正在遵循 MySQL 文档中的说明，并运行以下命令：
CREATE USER 'a' IDENTIFIED BY 'a';
GRANT ALL ON *.* TO 'a' REQUIRE SSL;
FLUSH PRIVILEGES;
然后，如果“protectme”是运行 MySQL 的计算机，我从远程计算机运行以下命令，
mysql -u a --password=a --host=protectme
它连接！我可以验证我连接的 MySQL 确实是“protectme”上的 MySQL。为了更好地衡量，我尝试重新启动 MySQL，并确认用户已在 mysql.user 表中更新：
mysql> SELECT * FROM mysql.user WHERE User = "a";

有谁知道我做错了什么？互联网上似乎没有其他人遇到这个问题，但它对我根本不起作用！非常感谢！
