mysql - 由于证书错误，无法为 Fabric-ca 服务器设置 mysql 数据库

Question

我正在尝试使用以下链接使用 mysql 数据库设置 Hyperledger Fabric-ca:http://fabric-ca.readthedocs.io/en/latest/users-guide.html

按照链接中的内容，我尝试使用 mysql 设置 Fabric-ca-server 作为数据库，并在 Fabric-ca-server-config.yaml 中指定以下配置

db:
  type: mysql
  datasource: root:rootpw@tcp(localhost:3306)/ca?parseTime=true&tls=custom
  tls:
      enabled: true
      certfiles:
        - server-cert.pem
      client:
        certfile: client-cert.pem
        keyfile: client-key.pem

我使用docker容器来启动mysql数据库:

docker run --name=mysql --env="MYSQL_ROOT_PASSWORD=mypassword" -p 3306:3306 -p 33060:33060 mysql

在我的容器启动后，会生成这些日志:

[System] [MY-010116] [Server] /usr/sbin/mysqld (mysqld 8.0.17) starting as process 1
[Warning] [MY-010068] [Server] CA certificate ca.pem is self signed.

当我启动 Fabric-ca-server 时，就会生成这些日志:

[INFO] Home directory for default CA: /home/trinayan/Documents/biltinetwork/newca
[INFO] Operation Server Listening on [::]:36189
[INFO] Listening on http://0.0.0.0:7054

我不明白为什么会出现这个错误:

[ERROR] Error occurred initializing database: Failed to connect to MySQL database: x509: certificate is valid for MySQL_Server_8.0.17_Auto_Generated_Server_Certificate, not localhost

因为这与 ssl 证书有关，所以任何人都可以帮助我。

Answer 1

从错误中，我假设您正在尝试通过 TLS 连接到 MySQL。 看起来 MySQL 自动生成了一个服务器证书，其通用名称或 SAN 为 MySQL_Server_8.0.17_Auto_Generate_Server_Certificate。 可能在您的配置中，您尝试连接到与 MySQL_Server_8.0.17_Auto_Generate_Server_Certificate 不匹配的 localhost。

所以你有几个选择:

• 关注 https://dev.mysql.com/doc/refman/8.0/en/creating-ssl-rsa-files-using-mysql.html并使用 openssl 生成证书，并将通用名称或 SAN 设置为 localhost

• 在运行 CA 和 MySQL 的主机服务器上创建一个主机条目，将 MySQL_Server_8.0.17_Auto_Generate_Server_Certificate 映射到 127.0.0.1 并替换 localhost 与 Fabric-ca-server 配置文件中的 MySQL_Server_8.0.17_Auto_Generate_Server_Certificate 。

• 不要使用 TLS，看看是否有效

我会选择第一个选项。
