我阅读了此文档https://hyperledger-fabric-ca.readthedocs.io/en/release-1.0/users-guide.html#mysql-ssl-configuration以设置 fabric-ca-server 使用 ssl 连接到 mysql。我使用openssl生成CA文件，并将客户端文件复制到fabric-ca-server（通过docker-compose中的volumns）
这是fabric-ca-server中关于tls的变量：
- FABRIC_CA_SERVER_DB_TLS_CERTFILES=/etc/hyperledger/fabric-ca-server-config/mysql-ssl/ca.pem
- FABRIC_CA_SERVER_DB_TLS_CLIENT_CERTFILE=/etc/hyperledger/fabric-ca-server-config/mysql-ssl/client-cert.pem
- FABRIC_CA_SERVER_DB_TLS_CLIENT_KEYFILE=/etc/hyperledger/fabric-ca-server-config/mysql-ssl/client-key.pem
我在fabric-ca容器中获取日志：

我还使用其他方式连接到 mysql：一种是启动另一个 mysql 容器作为客户端，以使用 ssl 连接到 mysql 服务器；另一种是通过将 mysql 服务器端口暴露给我的主机，在我的主机中使用 MySQLWorkbench 和 ssl。
以这种状态SELECT sbt.variable_value AS tls_version, t2.variable_value AS cipher, processlist_user AS user, processlist_host AS host FROM performance_schema.status_by_thread AS sbt JOIN performance_schema.threads AS t ON t.thread_id = sbt.thread_id JOIN performance_schema.status_by_thread AS t2 ON t2.thread_id = t.thread_id WHERE sbt.variable_name = 'Ssl_version' and t2.variable_name = 'Ssl_cipher' ORDER BY tls_version;
所以，我想知道我生成的认证有效，但是fabric-ca代码有问题吗？
