Mysql 启用ssl后拒绝访问

我是MySQL的新手，我正在尝试在MySQL版本5.5.6中启用SSL。 我遵循了此链接中的步骤

在执行步骤5之前的步骤之后，我可以看到在执行查询时启用了SSL：

show variables like '%ssl%';

+---------------+----------------------------+
| Variable_name | Value                      |
+---------------+----------------------------+
| have_openssl  | YES                        |
| have_ssl      | YES                        |
| ssl_ca        | /etc/certs/ca.pem          |
| ssl_capath    |                            |
| ssl_cert      | /etc/certs/server-cert.pem |
| ssl_cipher    |                            |
| ssl_key       | /etc/certs/server-key.pem  |
+---------------+----------------------------+

create user 'ssluser'@'%' identified by 'sslpassword' REQUIRE X509;

现在我无法执行查询：

show variables like '%ssl%';

+---------------+----------------------------+
| Variable_name | Value                      |
+---------------+----------------------------+
| have_openssl  | YES                        |
| have_ssl      | YES                        |
| ssl_ca        | /etc/certs/ca.pem          |
| ssl_capath    |                            |
| ssl_cert      | /etc/certs/server-cert.pem |
| ssl_cipher    |                            |
| ssl_key       | /etc/certs/server-key.pem  |
+---------------+----------------------------+

create user 'ssluser'@'%' identified by 'sslpassword' REQUIRE X509;

但我得到了信息：

 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'REQUIRE X509' at line 1

所以我在后面执行了这个查询：

CREATE USER 'ssluser'@'%' IDENTIFIED BY 'sslpassword';
GRANT USAGE ON *.* TO 'ssluser'@'%' REQUIRE X509;
FLUSH PRIVILEGES; 

现在我已经执行了此操作，并且启用了SSL，当我尝试以“ssluser”身份登录时，无论是否使用证书和密钥，我都被拒绝登录：

mysql -u ssluser -p 

或

其中：

ERROR 1045 (28000): Access denied for user 'ssluser'@'localhost' (using password: YES)

因此，我很困惑这是如何工作的，比如用户是否应该使用证书和密钥登录。用户是否被授予Require X509必须并且应该使用证书和密钥登录？任何帮助都将不胜感激。提前谢谢
