我正在尝试使用 PHP 连接到 mysql 数据库，但它不起作用

Question

I've Installed mysql, php, apache using a wamp configuration Where to access localhost is would be http://localhost:81 the PHP script I'm using is

if(mysql_connect('localhost', 'root', 'exobytes15')) {
mysql_select_db('testDB');
}
else {
echo 'Could not Connect to the database';
 }

But this gives me the error

1045: Access denied for user 'root'@'localhost' (using password: YES)

What should I do to fix this problem?

Answer 1

Make sure you have that your database is running, and that the user has access to it.

You can use either use the plain old mysql commandline client for this or phpmyadmin if your wamp stack has that installed.

Answer 2

You're connecting with the wrong password: Reset the password

or more likely: you don't have privileges to connect from localhost. Run the command:

GRANT ALL PRIVILEGES ON *.* TO 'root'@localhost WITH GRANT OPTION;

Test to see if you can connect.

Never do: GRANT ALL PRIVILEGES ON *.* TO 'root'@% WITH GRANT OPTION;

Because that will put your database server at risk from remote login attempts.

Answer 3

Either you didn't grant root@localhost the necessary rights to access the database or you're providing the wrong password.

Note: granting access to root@`%` does NOT grant access to root@localhost...

Answer 4

Maybe u are running mysql on a port other than the default port.

If it is the case use this:

mysql_connect('localhost:PORT', 'root', 'exobytes15')
