Question

I got mysql database in the phpmyadmin, and i try to connect to the database from my application.

My connection string is:

Server=12.919.18.12;Port=3306;Database=hbd;Uid=hb;Pwd=123;

An exception occurs:

"Unable to connect to any of the specified MySQL hosts."

Do I need to install mysql or something?

(I just imported MySql.Data.dll and tryied it. Is there anything I have forgotten? I checked the ip pinging my website).

Answer 1

Connection strings for MySQL
is pretty helpful in terms of connection strings. Your connection
string seems to be invalid.

You may check mysql server is working or not and you can add port number of mysql in connection string like this

“Server=myServerAddress;Port=1234;Database=myDataBase;Uid=myUsername;Pwd=myPassword;”

Other reason MySql might be configured to listen to only the local host.
