【问题描述】：

我是 python 新手。我正在尝试使用 python 连接到 mysql。这是下面的代码：

import mysql.connector
import sshtunnel

with sshtunnel.SSHTunnelForwarder(
    ssh_username="ravi",
    ssh_address="maxim.com",
    ssh_pkey="~/.ssh/id_rsa_host",
    remote_bind_address=("127.0.0.1", 3306),
) as tunnel:
    connection = mysql.connector.connect(
        user="power_pack",
        password="987654",
        host="db.maxim.com",
        port=3306,
    )

我收到以下错误：

 Traceback (most recent call last):

    m = self.BEGIN_TAG.match(lines[start])
 IndexError: list index out of range

同时将密钥传递给 paramiko 可以正确解析文件，

paramiko.RSAKey.from_private_key_file("~/.ssh/id_rsa_host")

【问题讨论】：

您的私钥文件似乎为空或不完整，因为错误来自paramiko 包尝试读取密钥时。你可以使用相同的文件在终端中启动 SSH 会话吗？
是的，它在终端中运行良好
同样使用 Paramiko 文件私钥被正确解析。但是当我通过 ssh 隧道时它会中断。

【解决方案1】：

感谢大家的回复。

这似乎是 Paramiko 的问题。 Paramiko 代码循环遍历各种类型的 SSH 密钥。如果第一个键类型不匹配。
并且添加了一个 PR 来修复这个错误，但它仍然没有合并。一世在本地进行更改以使其正常工作。
