将 MySQL 数据库连接到 Apache Superset

Connecting a MySQL database to Apache Superset

我正在尝试将 MySQL 数据库连接到 Apache Superset,但报告了以下错误:

sqlalchemy.exc.OperationalError: (_mysql_exceptions.OperationalError) (1045, "Access denied for user 'supersetuser'@'localhost' (using password: YES)")

我在本地端口 8889 上将 MAMP 与 MySQL 运行 一起使用。我正在尝试使用用户 supersetuser 的凭据连接数据库 apache_superset。 我试图在 Apache Superset 中传递的 SQLAlchemy URI 如下所示:

mysql://supersetuser:superset@localhost:8889/apache_superset

我很确定凭据是正确的,因为我刚刚创建了它们。 此外,我还尝试将所需的权限分配给用户

GRANT ALL PRIVILEGES ON `apache_superset`.* TO 'supersetuser'@'localhost' WITH GRANT OPTION;

但我仍然无法将数据库连接到 Apache Superset。

我设法通过将 localhost 替换为 127.0.0.1

找到了解决方案

因此完整的 SQLAlchemy URI 变为:

mysql://supersetuser:superset@127.0.0.1:8889/apache_superset 

根据 documentation:

On Unix, MySQL programs treat the host name localhost specially, in a way that is likely different from what you expect compared to other network-based programs. For connections to localhost, MySQL programs attempt to connect to the local server by using a Unix socket file. This occurs even if a --port or -P option is given to specify a port number. To ensure that the client makes a TCP/IP connection to the local server, use --host or -h to specify a host name value of 127.0.0.1, or the IP address or name of the local server.
