远程数据库连接字符串

Question

Hi I am new to PHP and MySQL I have created an application on LAMP and uploaded on net4.com a website hosting company. They are using phpMyAdmin in order to connect to the database which I am able to successfully the problem arises when I try to connect to database using php and query the database. I am using the mysql_connect() function which I have been using successfully on my local machine to connect to the remote database ie

$link = mysql_connect("118.67.248.12",  "username", "password");

where "118.67.248.12" is the ip address of the server where my database resides, it throws the following error:

"1045Access denied for user 'Technosaar'@'118.67.248.190' (using password: YES)"

and if I use localhost" in place of "118.67.248.12" it throws the following error:

"2002No connection could be made because the target machine actively refused it."

I am already bugged up calling "net4" support guyz but the problem still persist Somebody please help me out, May Day May Day!

Answer 1

The latter (localhost) isn't working I assume because the web server and database server aren't running on the same machine.

Are you certain that the password is set correctly on the server? This looks like an authentication error to me.

Answer 2

"1045 Access denied for user 'Technosaar'@'118.67.248.190' (using password: YES)" hints at missing access rights for the user Technosaar from your web server. Login to phpmyadmin and enter the command

show grants;

or

show grants for '<myuser'@'<host>';

There should be a line like

grant <privilege> on <mydatabase> to '<myuser>'@'<host>'

There you will see what access rights are configured for your user. If your webserver isn't listed, you must

grant all privileges on <mydatabase>.* to '<myuser>'@'<host>';

or whatever privileges you need for your database.

Insert the appropriate database name, user name and webserver host, of course.
