I have a MySQL server (v8.0) running on windows server 2016. I also have IIS running and PHPMyAdmin installed. In addition to this, I have a PHP web application which runs on the same server (under IIS) which accesses the MySQL database. Finally, I have several Python scripts which access the MySQL database.
Somehow, I have lost the ability to access the database from the Python scripts, but the web application still works and PHPMyAdmin can see and modify the database.
Even more strangely, I can no longer user MySQL Workbench to access the server from a PC on the local network, and PHPMyAdmin cannot access the users table of the mysql database. I can't change user details at all through PHPMyAdmin, I get the error:
Error in processing request
Error code: 500
Error text: Internal Server Error (rejected)
It seems that the connection to server has been lost.
MySQL Workbench gives me this error:
Your connection attempt failed for user 'user' to the MySQL server at SERVERADDRESS:PORT:
Access denied for user 'user'#'SERVERADDRESS' (using password: YES)
I have checked that the server can accept connections from remote computers by adding bind-address=0.0.0.0 to the my.ini file. I have also checked to ensure that 3306 is allowed through the firewall.
Any ideas on what could be causing this issue?
ADyson and MrApnea pointed me in the right direction.
The problem was caused by my main database user having the host reset from % to localhost, I'm not sure how this happened or when. As the app was running locally, this was not affected, but all other access was denied (including MySQL workbench). My root user is set to local only for security.
To fix this, I connected to the server via RDP and logged in to the console as the root user. I then ran these commands to see the error:
use mysql;
select host, user from user;
This showed me that the main user account had "localhost" in the host. I ran this command to update this user:
update user set host='%' where user='username' and host='localhost'; flush privileges;

I have created a free application using openshift, and created MySQL and phpmyadmin cartridges and inside my phpmyadmin I have gave access to all users from anywhere with all privileges now the problem is when I try to connect from my local MySQL workbench i get connected but I don't see my tables I have created in remote server using phpmyadmin and I can't do any action at all like creating schemas or tables where i get
ERROR 1044: Access denied for user ''#'localhost'
Remember that I allowed all privileges for any user, but I still get access denied for any action except only for the database connection.
Make sure the user you've given full permissions to is the same user MySQL Workbench is connecting as -- there's a difference between the hosts % and localhost for instance. From MySQL Workbench, issue the "Status" command and compare the username and host against what you've configured.
You're apparently connecting through 'localhost' so you have to give full permissions to the anonymous user with host localhost (or change your connection type to tcp so that your connection is via 127.0.0.1 instead of localhost).
Edit for further clarification: The MySQL permission structure treats different types of connections differently; a client connecting via TCP connection always appears to come from an IP address, even if it's from the "local host" (in the sense of being on the same machine), in which case that IP address of the incoming connection may be 127.0.0.1. Socket type connections are registered in MySQL as coming from the host "localhost" (literally, in this case). This is why we're verifying which host MySQL Workbench is connecting as.
Different connection types appear differently to MYSQL even if they're coming from the same "local machine." Furthermore, the wildcard host does not include 'localhost' socket connections, those are a separate entry in the permissions field with the 'localhost' host name; the wildcard does not apply, as I explained above. This is the reason why we're checking which permissions you set against what MySQL Workbench is connecting as; it's the most common cause of difficulties such as these.
I have set up a MySQL server on Debian Linux and need to access a database on this server via vb.net. I found some help on Code Project to download the connector.net library and build a class to access the MySQL database. However when I try to connect I get the authentication error below when attempting to establish a connection with the mysql server:
Authentication to host '192.168.68.47' for user 'root' using method 'mysql_native_password' failed with message: Access denied for user 'root'#'' (using password: YES)"} System.Exception
It seems that the library is appending the Windows workstation and domain to the user name and I am getting error. I tried using the root user with "#IPaddress" of the workstation, but it simply appended the workstation name and domain to this user. I also tried with another user besides root.
This is perfectly logic, because on your mysql server you need to Grant access to your host so it will be allowed to connect to, you can do it by following instructions in the following
Link
Also in the mysql configuration file, in your case : /etc/mysql/my.cnf you need to delete the line
bind-address = 127.0.0.1
This line will restrict all access from remote hosts, deleting it will allow access from remote hose which is what you want to do.
Hope this helps.
I'm trying to connect to MySQL, using Sequel Pro, something I have done many times before. Host 127.0.0.1, username root, no password. I get the following message:
Unable to connect to host 127.0.0.1 because access was denied.
Double-check your username and password and ensure that access from your current location is permitted.
MySQL said: Access denied for user 'root'#'localhost' (using password: NO)
For what it's worth, I got this message after upgrading to a new Mac OS (Mavericks), realized that the server wasn't running, downloaded a new server (which is currently running), and tried again - but I had the same problem.
Make sure you are running MySql in background System Preferences -> Mysql -> Start MySql
Make sure you are able to connect to MySql through command line, if command line works, there is no reason why it should not work in SequelPro.
If problem still persists, try changing the 'root' password.
It happened to my in Mac. I went to system preferences -> MySQL -> Stopped the server, started it again, and it worked.
I've installed XAMPP. I had put up security barriers but as time went by I forgot my credentials and could no longer access the MySQL server through phpMyAdmin. I keep having the following error trying to enter phpMyAdmin:
1045 Cannot log in to the MySQL server.
I've edited C:\xampp\phpMyAdmin\config.inc to change my passwords but I had no success afterwards. I've altered the bit:
Authentication method (config, http or cookie based)
$cfg['Servers'][$i]['user'] = 'xxxxx' ;
$cfg['Servers'][$i]['password'] = 'yyyy' ;
I've run the MySQL resetroot batch file without success.
I've changed the default ports on my Apache and Mysql at the localhost a couple weeks ago and now I can't access mysql.exe.
Can't connect to MYSQL service on 'localhost'(10061).
How can I change the default localhost port?
Did you take a look here?
After installing a local server and trying to access phpMyAdmin, you could possibly encounter the error: #1045 Access Denied for user 'root'#'localhost' (using password: YES).
If root#localhost wasn't granted the necessary rights to access the database or you provided the wrong password, you will then encounter this error.
Following this tutorial will help guide you on bypassing this error, for any local host server using phpMyAdmin.
I am running MySQL on an Amazon AWS Instance. I was able to previously connect to the MySQL Database via MySQL Query Browser. Now I am traveling outside the U.S. and I am having trouble connecting via the Query Browser. I am able to use Terminal to create an ssh connection and then login to MySQL, so it does not appear to be a larger issue with the MySQL Database.
Has anyone else had a similar problem? Any ideas how I can fix this?
This is the error I get from the MySQL Browser
Your connection attempt
failed for user 'admin' from your host to server at
ec2-XXX-XXX-XXX-XXX.compute-1.amazonaws.com:3306: Can't connect to
MySQL server on 'ec2-XXX-XXX-XXX-XXX.compute-1.amazonaws.com' (4)
Please: 1 Check that mysql is running on server
ec2-XXX-XXX-XXX-XXX.compute-1.amazonaws.com
2 Check that mysql is
running on port 3306 (note: 3306 is the default, but this can be
changed)
3 Check the admin has rights to connect to
ec2-XXX-XXX-XXX-XXX.compute-1.amazonaws.com from your address (mysql
rights define what clients can connect to the server and from which
machines)
4 Make sure you are both providing a password if needed and
using the correct password for
ec2-XXX-XXX-XXX-XXX.compute-1.amazonaws.com connecting from the host
address you're connecting from
The only possible problem I see could be #4, but I ran and re-ran this command via Terminal:
grant all privileges on *.* to 'admin'#'%' identified by '<pass>' with grant option;
