在 python 问题中从 SQLalchemy 连接到 Synology NAS 上的 MariaDB 数据库

Question

进一步深化我的问题 here，我试图以更简单的方式提出这个问题。

按照本教程，我正在尝试使用 SQLalchemy 远程启动到我 NAS 中的 Mariadb 数据库的连接。这是代码：

# Module Imports
import mariadb
import sys


user = "my_name"
passwd = "my_pass"
host = "192.168.1.111"
db = "test"
port= "3307"

# Connect to MariaDB Platform
try:
    conn = mariadb.connect(
        user=user,
        password=passwd,
        host=host,
        port=3307,
        database=db

    )
except mariadb.Error as e:
    print(f"Error connecting to MariaDB Platform: {e}")
    sys.exit(1)

# Get Cursor
cur = conn.cursor()

然后我得到这个错误：

ERROR:root:Internal Python error in the inspect module.
Below is the traceback from this internal error.

Error connecting to MariaDB Platform: Can't connect to server on '192.168.1.111' (36)

    conn = mariadb.connect(

    frameinfo = (tb.tb_frame,) + getframeinfo(tb, context)
AttributeError: 'tuple' object has no attribute 'tb_frame'

我已经安装了 brew mariadb-connector-cand ； brew 安装了 mariadb；和 pip 安装 PyMySQL。

有人愿意帮忙吗？

我赞同@Tim Roberts。转到您的 NAS“已安装包”，单击 MariaDB 10 应用程序。在其中请确保数据库可通过 Intranet 或 Internet 共享。它被称为 TCP/IP 连接。检查它，您的连接将正常工作。

这是很多人在第一次启动 Mariadb 时忘记的一点。
