The hint says the password is wrong, you say the password is wrong, but everybody who knows is your password wrong right?

Look here

User name, password is wrong?

User name, password is wrong?

if (mysql_connect ("localhost", "root", "123456")) {
echo "Success";
} can show success.

But Access denied for user ' root ' @ ' localhost ' (using Password:no)
I mean, there's no password for the connection.

But Access denied for user ' root ' @ ' localhost ' (using Password:no)
Is that there is no solution to the password given when connecting.

It's easy, you'll know when you test it.
Known
mysql_connect ("localhost", "root", "123456")
Can connect successfully
So
mysql_connect ("localhost", "root", "12345"); Note that I intentionally removed the last 6 of the password.
Error Access denied for user ' root ' @ ' localhost ' (using Password:yes)

mysql_connect ("localhost", "root"); Do not give a password
Error Access denied for user ' root ' @ ' localhost ' (using Password:no)

The problem is solved.
The configuration file is wrong-written.

Solved, but do not know why, the main configuration file config.php inside has
$config = Require './config.inc.php '; Config.inc.php inside is the common database configuration information
I deleted the config.inc.php to write the information directly in the main configuration file is actually OK ....
