无法使用 python 远程连接到 cpanel 中的 mysql 数据库

Question

I tried to connect remotely to my database in cpanel in all ways but it won't let me, does anyone know why it doesn't give me access?

HOST = "xxxxxxxxx"
DATABASE = "xxxxxxxxx"
USER = "xxxxxxxxxxx"
PASSWORD = "xxxxxxx"

db_connection = mysql.connect(host=HOST, database=DATABASE, user=USER, password=PASSWORD)
print("Connected to:", db_connection.get_server_info())

During handling of the above exception, another exception occurred:

Answer 1

在cpanel中，当您尝试远程连接并且端口3306拒绝访问时，您必须联系cpanel提供商并检查提供远程访问的计划，因为如果端口3306被阻止，远程连接计划可能会受到限制，这只是一个问题与提供 cpanel 的提供商交谈

Answer 2

I would suggest:

1. Ask your hosting provider if they ALLOW remote MySQL connections.
2. Ask your host if port 3306 is open.

If the above is covered, then you will need to:

1. Add the IP address of the remote machine ( where you are trying to establish this connection ) to "Remote MySQL" in cPanel.
2. Use your server's hostname or IP as the MySQL Host in your connection configuration.

And if you still cannot establish a successful connection, I recommend switching to a managed hosting provider that fully supports remote MySQL connections. You can check for a suitable one here: https://hostadvice.com/
