Python MySQLConnection错误：拒绝用户访问'；rnd管理员'@'；本地主机'；（使用密码：是）

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

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，一切正常，没有检测到错误，并且mysqlcli被打开

        with SSHTunnelForwarder(
                ('myhost', 22),
                ssh_username="root",
                ssh_password="passwd",

            if tunnel.is_active:
                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

通过从config.ini中删除

3306

mysql默认端口并手动将

port=tunnel.local\u bind\u port

输入到MySQLConnection构造函数中，修复了此问题

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

我正要说你根本没有使用SSHTunnelForwarder的端口，但你找到了答案。：）我还建议确保

主机总是
127.0.0.1
（因为这是隧道绑定的地方）：
db_config=read_db_config（）；db_config.update（host='127.0.0.1'，port=tunnel.local_bind_port）
