禁用MariaDB上的ssl，可以'；t在Debian和YaSSL上启用SSL

我正在尝试在Raspberry 3上设置MariaDB和TLS，并在安装了LAMP的情况下运行。玛丽亚DB 10.1.23

我遵循官方文件，也尝试了

但是，当我查看变量时，have_ssl保持禁用状态

    MariaDB [(none)]> SHOW VARIABLES LIKE '%ssl%';
+---------------------+--------------------------------+
| Variable_name       | Value                          |
+---------------------+--------------------------------+
| have_openssl        | NO                             |
| have_ssl            | DISABLED                       |
| ssl_ca              | /etc/mysql/ssl/ca-cert.pem     |
| ssl_capath          |                                |
| ssl_cert            | /etc/mysql/ssl/server-cert.pem |
| ssl_cipher          |                                |
| ssl_crl             |                                |
| ssl_crlpath         |                                |
| ssl_key             | /etc/mysql/ssl/server-key.pem  |
| version_ssl_library | YaSSL 2.4.2                    |
+---------------------+--------------------------------+
10 rows in set (0.01 sec)

这是我的/etc/mysql/mariadb.conf.d/50-server.cnf

#
 ssl-ca=/etc/mysql/ssl/ca-cert.pem
 ssl-cert=/etc/mysql/ssl/server-cert.pem
 ssl-key=/etc/mysql/ssl/server-key.pem
#
# Accept only connections using the latest and most secure TLS protocol version.
# ..when MariaDB is compiled with OpenSSL:
# ssl-cipher=TLSv1.2
# ..when MariaDB is compiled with YaSSL (default in Debian):
 ssl=on

尝试openssl s_客户端时，我得到以下结果：

openssl s_client -state -nbio -debug -connect 127.0.0.1:3306 | grep "ssl"
SSL_connect:before SSL initialization
SSL_connect:SSLv3/TLS write client hello

我还尝试从另一个Raspi连接，结果如下：

root@DietPi:/etc/mysql/ssl# openssl s_client -state -nbio -debug -connect 192.168.1.89:3306 | grep "^ssl"
SSL_connect:before/connect initialization
SSL_connect:SSLv2/v3 write client hello A
SSL_connect:error in SSLv2/v3 read server hello A
SSL_connect:error in SSLv2/v3 read server hello A
548036626192:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:782:

到目前为止，我的研究不是很成功。没有有效的解决方案，也不适合我的环境。我还试图安装，但安装

cpan App:：cpanminus

失败，原因是

Writing MYMETA.yml and MYMETA.json
  MIYAGAWA/App-cpanminus-1.7044.tar.gz
  /usr/bin/perl Makefile.PL INSTALLDIRS=site -- OK
Running make for M/MI/MIYAGAWA/App-cpanminus-1.7044.tar.gz
  MIYAGAWA/App-cpanminus-1.7044.tar.gz
  make -- NOT OK

明天我将尝试安装analyze-ssl.pl或打开另一个线程。只是想解释一下我是怎么做的

如果有人能帮我解开谜语，我会很高兴的

谢谢！

您可以尝试将openssl默认生成的PKCS#8密钥转换为mariadb的PKCS#1密钥

openssl rsa -in pcks#8.key -out pkcs#1.key 

这次手术后，我说

MariaDB [(none)]>  SHOW VARIABLES LIKE '%ssl%';
+---------------------+-----------------------------------------------+
| Variable_name       | Value                                         |

大卫也有同样的问题。@David的解决方案对我不起作用，但这有助于：
