	# 定义ssh连接

        print('SSH连接成功')
        
        # 此处host为127.0.0.1 是ssh连接完之后会映射到本地127.0.0.1的地址
        conn = pymysql.connect(host='127.0.0.1',
                                # ssh server 映射的端口

	    print('mysql数据库连接成功')
	    cursor = conn.cursor()
	
	    df = pd.read_sql("show tables;", con=conn)
	    print(df)
	    cursor.close()
	    conn.close()

输出结果
