Question

我正在尝试通过以下链接使用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作为DB来设置fabric-ca-server，并在fabric-ca-server-config.yaml中指定相同的以下配置

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

我已使用docker容器通过以下方式启动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，将生成以下日志：

[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.
[Warning] [MY-011810] [Server] Insecure configuration for --pid-file: Location '/var/run/mysqld' in the path is accessible to all OS users. Consider choosing a different directory.

[System] [MY-011323] [Server] X Plugin ready for connections. Socket: '/var/run/mysqld/mysqlx.sock' bind-address: '::' port: 33060

当我启动fabric-ca-server时，将产生以下日志：

[INFO] Configuration file location: /home/trinayan/Documents/biltinetwork/newca/fabric-ca-server-config.yaml
[INFO] Starting server in home directory: /home/trinayan/Documents/biltinetwork/newca

[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

我不知道为什么会出现此错误：

[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。

从该错误中，我假设您正在尝试通过TLS连接到MySQL。看起来MySQL自动生成了具有公用名或SAN为index.html的服务器证书。可能是在您的配置中，您尝试连接到与MySQL_Server_8.0.17_Auto_Generated_Server_Certificate不匹配的localhost。

所以您有一些选择：

遵循https://dev.mysql.com/doc/refman/8.0/en/creating-ssl-rsa-files-using-mysql.html，并使用openssl将通用名称或SAN设置为MySQL_Server_8.0.17_Auto_Generated_Server_Certificate
在运行CA和MySQL的主机服务器上创建主机条目，该条目将localhost映射到MySQL_Server_8.0.17_Auto_Generated_Server_Certificate，并在Fabric-ca中将127.0.0.1替换为localhost -server配置文件。
不使用TLS并查看一切是否正常

我会选择第一个选项。

由于证书错误，无法为fabric-ca服务器设置mysql数据库
