我正在尝试为 MySQL启用SSL连接 – SSL将在MysqL中显示为启用,但由于此错误,我无法建立任何连接：ERROR 2026(HY000)：SSL连接错误：ASN：其他签名确认错误

我正在运行以下内容：

Ubuntu Version: 14.04.1 LTS (GNU/Linux 3.13.0-34-generic x86_64)
MysqL Version: 5.5.38-0ubuntu0.14.04.1
OpenSSL Version: OpenSSL 1.0.1f 6 Jan 2014

我使用这些命令生成我的证书(所有在/ etc / MysqL中生成)：

openssl genrsa -out ca-key.pem 2048
openssl req -new -x509 -nodes -days 3650 -key ca-key.pem -out ca-cert.pem -subj "/C=US/ST=NY/O=MyCompany/CN=ca"

openssl req -newkey rsa:2048 -nodes -days 3650 -keyout server-key.pem -out server-req.pem -subj "/C=US/ST=NY/O=MyCompany/CN=server"
openssl rsa -in server-key.pem -out server-key.pem
openssl x509 -req -in server-req.pem -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 -out server-cert.pem

openssl req -newkey rsa:2048 -nodes -days 3650 -keyout client-key.pem -out client-req.pem -subj "/C=US/ST=NY/O=MyCompany/CN=client"
openssl rsa -in client-key.pem -out client-key.pem
openssl x509 -req -in client-req.pem -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 -out client-cert.pem

我把以下内容放在my.cnf中：

[MysqLd]    
ssl-ca=/etc/MysqL/ca-cert.pem
ssl-cert=/etc/MysqL/server-cert.pem
ssl-key=/etc/MysqL/server-key.pem

当我尝试连接指定客户端证书时 – 我收到以下错误：

MysqL -uroot -ppassword --ssl-ca=/etc/MysqL/ca-cert.pem --ssl-cert=/etc/MysqL/client-cert.pem --ssl-key=/etc/MysqL/client-key.pem

ERROR 2026 (HY000): SSL connection error: ASN: bad other signature confirmation

如果我没有SSL连接,我可以看到MysqL已正确加载证书：

MysqL -uroot -ppassword --ssl=false

MysqL> SHOW VARIABLES LIKE '%ssl%';
+---------------+----------------------------+
| Variable_name | Value                      |
+---------------+----------------------------+

| have_ssl      | YES                        |

| ssl_cert      | /etc/MysqL/server-cert.pem |
| ssl_cipher    |                            |
| ssl_key       | /etc/MysqL/server-key.pem  |
+---------------+----------------------------+
7 rows in set (0.00 sec)

我生成的证书通过了OpenSSL验证和模数：

openssl verify -CAfile ca-cert.pem server-cert.pem client-cert.pem
server-cert.pem: OK
client-cert.pem: OK

我错过了什么？我以前在不同的服务器上使用过相同的过程并且它工作 – 但是Ubuntu版本是12.04 LTS而OpenSSL版本更旧(不记得具体).最新的OpenSSL有什么变化吗？

任何帮助,将不胜感激！
