GBase 8a支持数据库用户通过require ssl参数，强制必须使用SSL连接数据库，本文介绍其方法。

创建用户
查看其中的ssl_type, 看到是空的。

通过grant 命令，设置权限，require ssl参数要求必须用ssl连接。查看user表的ssl_type变成了ANY，而不是默认的空。

登录尝试
因为并没有配置ssl,所以直接报错，虽然用户名和密码是对的。
[gbase@rh6-1 gcluster]$ gccli -ussl_user -pssl
ERROR 1045 (28000): Access denied for user 'ssl_user'@'localhost' (using password: YES)
