Kích hoạt Python để kết nối với MySQL thông qua SSH Tunneling

Chỉ điều này làm việc cho tôi

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()
