Tidak dapat terhubung ke server mysql di localhost:3306 python

Masalahnya adalah saya tidak dapat terhubung dari host jarak jauh (berbeda dari "localhost") ke database yang dihosting di PC A oleh pengguna "generik" melalui skrip Python

Saya mem-forwed port "3306" di firewall dan memodifikasi file konfigurasi "my. ini” sebagai berikut (khususnya saya memasukkan bind-address = 0. 0. 0. 0), tetapi tidak berhasil

#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
#
# You can copy this file to
# C:/xampp/mysql/bin/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is C:/xampp/mysql/data) or
# ~/.my.cnf to set user-specific options.
#
# In this file, you can use all long options that a program supports.
# If you want to know which options a program supports, run the program
# with the "--help" option.


# The following options will be passed to all MySQL clients
[client]
# password       = your_password

# Don't listen on a TCP/IP port at all. This can be a security enhancement,
# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.
# Note that using this option without enabling named pipes on Windows
# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
# log-bin deactivated by default since XAMPP 1.4.11
#log-bin=mysql-bin


# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended
#log-bin=mysql-bin

Di bawah kode Python untuk membuat koneksi dengan DB

import mysql.connector as mysql
import socket

hostname = socket.gethostname()
IP_address = socket.gethostbyname(hostname)


user=input("User: ")
password=input("Password: ")


db=mysql.connect(
    host=IP_address,
    user=user,
    port=3306,
    password=password,
    database="Example_db")


print("connected to: ",db.get_server_info())

Jika saya menggunakan pengguna "root" dari "localhost", saya dapat terhubung ke DB jika tidak koneksi gagal (E. g. Dari host jarak jauh yang berbeda dari localhost, Terhubung ke jaringan LAN Rumah yang sama)

Tidak dapat terhubung ke MySQL di localhost?

Bagaimana cara saya terhubung ke MySQL port 3306?

Bagaimana cara saya terhubung ke database MySQL lokal dengan python?

Bagaimana cara memeriksa apakah MySQL dapat dijangkau di port 3306?
