python - 启用 Python 通过 SSH 隧道连接到 MySQL

Question

我在 Python 2.7 中使用 MySqldb 以允许 Python 连接到另一个 MySQL 服务器

import MySQLdb
db = MySQLdb.connect(host="sql.domain.com",
     user="dev", 
      passwd="*******", 
      db="appdb")

不是像这样正常连接，而是如何使用 SSH key 对通过 SSH 隧道建立连接？

SSH 隧道最好由 Python 打开。 SSH隧道主机和MySQL服务器是同一台机器。

只有这个对我有用

import pymysql
import paramiko
import pandas as pd
from paramiko import SSHClient
from sshtunnel import SSHTunnelForwarder
from os.path import expanduser

home = expanduser('~')
mypkey = paramiko.RSAKey.from_private_key_file(home + pkeyfilepath)
# if you want to use ssh password use - ssh_password='your ssh password', bellow

sql_hostname = 'sql_hostname'
sql_username = 'sql_username'
sql_password = 'sql_password'
sql_main_database = 'db_name'
sql_port = 3306
ssh_host = 'ssh_hostname'
ssh_user = 'ssh_username'
ssh_port = 22
sql_ip = '1.1.1.1.1'

with SSHTunnelForwarder(
        (ssh_host, ssh_port),
        ssh_username=ssh_user,
        ssh_pkey=mypkey,
        remote_bind_address=(sql_hostname, sql_port)) as tunnel:
    conn = pymysql.connect(host='127.0.0.1', user=sql_username,
            passwd=sql_password, db=sql_main_database,
            port=tunnel.local_bind_port)
    query = '''SELECT VERSION();'''
    data = pd.read_sql_query(query, conn)
    conn.close()
