Question

我正在尝试通过ssh隧道连接到远程服务器上的mysql数据库。
与服务器建立连接后，我的脚本因mysql错误而失败：

root - ERROR - 1045 (28000): Access denied for user 'rnd-admin'@'localhost' (using password: YES)
Access denied for user 'rnd-admin'@'localhost' (using password: YES).

注意： 当我使用mysql -u rnd-admin -p从具有相同信用的终端连接到数据库时，一切都很好，没有检测到错误，并且打开了mysql cli 。

                db_config = read_db_config()
                conn = MySQLConnection(**db_config)

                cursor = conn.cursor()
                cursor.execute(query)
                result = cursor.fetchall()

                conn.commit()
                cursor.close()
                conn.close()

config.ini

[mysql]
host=127.0.0.1
port=3306
database=db-name
user=rnd-admin
password=pass

Answer 1

通过从config.ini中删除 3306 mysql默认端口并手动将port=tunnel.local_bind_port馈入 MySQLConnection 构造函数来解决此问题。

conn = MySQLConnection(**db_config, port=tunnel.local_bind_port)

MySQLConnection错误：用户'rnd-admin'@'localhost'的访问被拒绝（使用密码：是）
