hello database gurus,
i have another one for you guys. i am getting this error:

[root@bluebananas mysql]# mysql
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

i don't know what's going on. i can get in, however, after providing a password, using command:

[root@bluebananas mysql]# mysql -u root -p mysql

but using commands:
1) mysql (plain)
2) mysqladmin variables

gave me the access error.

i have a webserver running using apache and php (works fine). i'm trying to integrate and use mysql to my system. i copied a php script from a book to test my php-apache-mysql connection but its not giving me any expected output.

you will notice that i placed "echo" before and after mysql_connect. it showed "connecting" on the browser, but seemed to hang because it does not show "after connecction".

here's the code:
///// database_connection.php
<?php
$dbUser = 'test_user';
$dbPass = 'test_pass';
$dbName = 'my_test';
$dbHost = 'localhost';

echo "Connecting";

$sql = mysql_connect($dbHost, $dbUser, $dbPass)
or die (mysql_error());

echo "After Connection";

mysql_select_db($dbName, $sql) or die (mysql_error());
?>

///// database_insert.php
<?php
include ('database_connection.php');

for ($i = 0; $i <= 50; $i++)
{
if($i % 2)
{
$data = $i.' -Odd Result';
}
else {
$data = $i.' -Even Result';
}

mysql_query("INSERT INTO my_table (my_value, my_date)
VALUES ('$data', now())") or die (mysql_error());
echo "Inserting: $data<br />";
}
echo "Done<br />";
?>

where does mysql put its errors by the way?

thanks guys!

My guess, as I'm no guru yet, but did have the same problems you are having, is that the vanillya mysql command assumes the current user with no password. Now, this is fine if you don't care about security. My solution to this was to simply add to my ~/.bashrc file: Then the mysql command will use the current user, and prompt for a password.
This is my connection script for your reference:


Maybe, this will be a little more verbose, but the define statement may be a little more robust than just assigning a value? Maybe, a true guru can answer that one.

I don't know the answer to the last question, so hopefully someone else will come along with another answer.

I have upgraded from Debian lenny to squeeze, and voila I got the same error on the first reboot and all the time since. After a lot of swearing and searching I tried this command :: mysql_setpermission.

That fixed it for good.

You can even set up some new users and their passwords too.
