python通过ssh远程访问mysql

import mysql.connector as sql

with sshtunnel.SSHTunnelForwarder(
        ('192.168.0.x', 8889),#ssh 的地址和端口 
        ssh_username='ssh',   #ssh 用户名 
        ssh_password='123456',#ssh 密码
        remote_bind_address=('localhost', 3306),#远程机上登录mysql是用啥这里就写啥
        local_bind_address=('localhost', 3306)  #映射到本地用的地址和端口
) as tunnel:
    conn = sql.connect(
        host='localhost', #跟上面的local_bind_address里的要保持一样--默认是localhost,如果是默认，这行可以注释掉
        port=3306         #跟上面的local_bind_address里的要保持一样--默认是3306,如果是默认，这行可以注释掉
        user='root',
        password='megvii'
    )
    cursor = conn.cursor()
    query = "select version();"
    cursor.execute(query)
    data = cursor.fetchall()
    print(data)
