I have created a form and it is suppose to pass three variables onto my database. I not able to submit my variables to the database, it gives me this error:
"Warning: mysqli_connect() [function.mysqli-connect]: (28000/1045): Access denied for user 'username'#'xx.xx.xx.xx' (using password: YES) in /home/simples2/public_html/insert.php on line 2
Failed to connect to MySQL: Access denied for user 'username'#'xx.xx.xx.xx' (using password: YES)
Warning: mysqli_query() expects parameter 1 to be mysqli, boolean given in /home/simples2/public_html/insert.php on line 13
Warning: mysqli_error() expects parameter 1 to be mysqli, boolean given in /home/simples2/public_html/insert.php on line 15
Error:"
I am not sure what needs to be done here. I have checked for spellings, passwords and syntax to my best of abilities which is quite less but I am not able to do.
For this, I would verify that the MYSQL database user allows that username allows connections from that ip address. It seems that the user account was setup for 'username'#localhost or the password is incorrect

My company has a Perl application in server with IP : 10.10.3.39
And because of the new rule implemented, I must migrate the database to MySQL DB in server with IP : 10.10.1.18
My company DB administrator has create an account and grant the access for the apps with username : 'user'#'10.10.3.39'. So the account just can be used from server with IP 10.10.3.39
I tried the connection in the server using command mysql -h 10.10.1.18 -u user -p
[hanief#dev39 project]$ mysql -h 10.10.1.18 -u user -p
Enter password:

I have a database connection script test_db.pm in Perl like this:
use DBI;
$user = "user";
$pw = 'password';
$dbh = DBI->connect("DBI:mysql:database=mysql;host=10.10.1.18;mysql_enable_utf8=1",$user, $pw, %attr) or die "Cannot connect to MySQL server\n";
And then, I tried to run it using command perl test_db.pm, I got this error
[hanief#dev39 project]$ perl test_db.pm
DBI connect('database=mysql;host=10.10.1.18;port=3306;mysql_enable_utf8=1','user',...)
failed: Access denied for user 'user'#'%' to database 'mysql' at test_db.pm line 6.
Cannot connect to MySQL server
I don't know why the account name suddenly has #'%' behind it
I have tried to change the variable $user to :
$user = "user\#10.10.3.39";
failed: Access denied for user 'user#10.10.3.39'#'10.10.3.39' (using password: YES) at test_db.pm line 6.
$user = "user\#'10.10.3.39'";
failed: Access denied for user 'user#'10.10.3.39''#'10.10.3.39' (using password: YES) at test_db.pm line 6.
$user = "'user'\#'10.10.3.39'";
failed: Access denied for user 'user'#'10.10.3.39'#'10.10.3.39' (using password: YES) at test_db.pm line 6.
But still, didn't work. The server still can't connected to DB server.
I Don't know why there's an extra #'10.10.3.39' behind the user account.
And don't know why % before, suddenly changed to 10.10.3.39
Any solution for my case?
I'm not entirely sure what's going on here, but I think I can shed a little bit of light.
MySQL (and, hence, MariaDB) has a login system that isn't just dependent on usernames and passwords. It also takes into account the host that the connection is coming from. If you look at the mysql.user table, you'll see that the first three columns are Host, User and Password.
The Host column is interesting. It can either contain an IP address or a hostname, but it can also contain the symbol '%', which means "any host".
So when the DBA told you they had:
create an account and grant the access for the apps with username : 'user'#'10.10.3.39'
I'm betting they mean they've inserted the values user and 10.10.3.39 in the mysql.user table.
That means your $user variable needs to be set to user, not user#10.10.3.39 - as MySQL will work out the IP address from your incoming connection.
So when you see errors like this:
failed: Access denied for user 'user#10.10.3.39'#'10.10.3.39'
the bit inside the first pair of quotes ("user#10.10.3.39") is the username you're trying to use and the bit inside the second pair of quotes ("10.10.3.39") is the IP address that MySQL thinks you're connecting from. Obviously, that's not going to work because that username doesn't exist in the mysql.users table.
So, we're left looking at your first example:
$dbh = DBI->connect("DBI:mysql:database=mysql;host=10.10.1.18;mysql_enable_utf8=1",$user, $pw, %attr)
or die "Cannot connect to MySQL server\n";
Which gives this error:
failed: Access denied for user 'user'#'%'
Now, the fact that this error uses "%" as your hostname, seems to imply that the MariaDB server didn't recognise the IP address that you're coming from as one of the specific IP addresses listed as allowed for your user.
So, two things I would double-check in this instance:
Are you definitely trying to connect from 10.10.3.39? This includes checking if there are any proxies between you and the DB server that might change your IP address.
Is the IP address in the mysql.user table really 10.10.3.39? Or does the value, perhaps, contain a typo?
I'm aware that this isn't a "here's the solution to your problem" post but, hopefully, it explains a bit more about what is going on and gives you a couple of avenues to investigate.
I'm trying to log in to mysql via a bash script or to be more specific, I want to check if the passed parameters for the mysql user are thes of an admin user.
For this reason it has to be possible to log in to mysql via a one line command e.g.
mysql -u $dbadmin -p$dbadminpass
To test why I didn't work, I tried it myself on the command line an I'm getting this Error:
ERROR 1045 (28000): Access denied for user 'admin'#'localhost' (using password: YES)
I created the use on #localost and gave all privileges. All my reasarch had no reasults so far.
I checked for any typos
You can try this:
GRANT ALL PRIVILEGES ON *.* TO 'admin'#'%';
FLUSH PRIVILEGES;
or try to connect to 127.0.0.1 not to localhost
This is not a problem with MySQL installation or set-up.
Each account name consists of both a user and host name like 'user_name'#'host_name', even when the host name is not specified. From the MySQL Reference Manual: https://dev.mysql.com/doc/refman/8.0/en/privileges-provided.html#priv_usage
MySQL account names consist of a user name and a host name. This enables creation of accounts for users with the same name who can connect from different hosts.
This also allows MySQL to grant different levels of permissions depending on which host they use to connect.
When updating grants for an account where MySQL doesn't recognize the host portion, it will return an error code 1133 unless if it has a password to identify this account.
Also, MySQL will allow an account name to be specified only by it's user name, but in this case it is treated as 'user_name'#'%'.
I am getting error in PhpMyAdmin
mysqli_real_connect(): (HY000/1045): Access denied for user
'phpmyadmin'#'localhost' (using password: YES)
Connection for controluser as defined in your configuration failed.
It is not dublicate - see the error using password - YES
follow the below steops..
1. You cannot explicitly specify that a given user should be denied access. ...
2. You cannot specify that a user has privileges to create or drop tables in a database but not to create or drop the database itself.
3. A password applies globally to an account.
4. give previledge as Yes to phpmyadmin
Hi I tried to connect to mysql using the wrong password. I finally made it there but now as I try to reach my homepage www.hari.se I just get following ;
Warning: mysql_connect(): Access denied for user 'hari.se'#'csea04.cliche.se' (using password: YES) in /home/virtual/hari.se/public_html/PHP/db.php on line 2

Please friends anyone who can help? Hari
your script is not able establish the connection to the database
also you should insert true information about the mysql connection into db.php file
and you can't insert the wrong password !!!!
you have some variable in this file
similar to below:
$database_hostname = 'localhost (as default) or your server hostname';
$database_username = 'root (as default) or your database username';
$database_password = '(in some local web servers we don't have any password for database but in hosting servers usually we have a defined password ) such as (3R8=&3pHEJ+J)';
$database_name = 'you must insert your database name in here';
$connection_mysql=mysql_connect($database_hostname,$database_username,$database_password);
mysql_select_db($database_name,$connection_mysql);
--------------
or in the simple mode might be similar below:
$connection_mysql=mysql_connect(localhost,your_database_name,your_database_password);
mysql_select_db($database_name,$connection_mysql);
i think your information is incorrect please check your entered information in db.php (also the low level Possibility is your account suspended or limited in server by admin)
Does anyone know why I would be getting an Access Denied error using XAMPP on OS X?
When I go to localhost/phpmyadmin I get the message #1045 - Access denied for user 'root'#'localhost' (using password: YES)
and when I go to just localhost I get
Access forbidden!
You don't have permission to access the requested directory. There is
either no index document or the directory is read-protected.
Is this a permissions issue? I added the password root to the username root in the phpmyadmin config file, but that didn't work and it wouldn't explain why I am getting the error on localhost as well. What IS working is the virtual host I created called my.server, but other than that, I seem to be locked out for some reason.
This error:
#1045 - Access denied for user 'root'#'localhost' (using password: YES)
Is a MySQL error. That's saying that there was an attempt to connect to the MySQL server, and either the specified user account doesn't exist, or the passwords don't match. From another client that can connect, verify the user account exists
SELECT u.user, u.host, u.password
FROM mysql.user
WHERE u.user = 'root'
AND u.host = 'localhost'
If the password column is empty, then there's no password on that account. If there's a '*688D...' value in there, you can compare the value of the hash of the password you're supplying...
SELECT PASSWORD('mysecretpassword')
Also, I'd recommend you create a DIFFERENT database user account (other than 'root'#'localhost', for use by your PHP scripts. (As one advantage, this will allow you to apply the security principle of "least privilege", granting only the privileges required.
The other error is saying that the webserver isn't configured to allow access to the URI you've specified, in the case of "http://localhost/", the webserver isn't configured to allow access to the ROOT of the webserver directory. (This is usually a really a good thing, in terms of security, not exposing the contents of this directory.)
