I have Centos 6 with MySQL 5.7 installed
when i restart computer and trying to access web site i recive next error:
Software error:
Can't connect to the database.
Error: Access denied for user ''#'localhost' to database 'bugzilla_DB'
Is your database installed and up and running?
Do you have the correct username and password selected in localconfig?
if i connect to server and restart HTTPD service all start working untill next restart.
i checked:
1. mysql starts a lot before httpd
2. waiting few minutes after server starts not help until i make httpd restart
3. mysql.pid and mysql.sock are ok
4. selinux disabled
5. iptables not used and disabled
6. no additional error in mysql.log
This seems to be related to your web site source code trying to access MySQL.
You need to enter the right connection (host and port) info and user credentials in your source code (wherever authentication is made).
This has nothing to do with (the erratic premise) that Apache connects to MySQL. It does not (in any normal out-of-the box installation).
This being said, you should still provide more information, the following statement requires more facts about your setup:
if i connect to server and restart HTTPD service all start working untill next restart.
I Found the problem. RiggsFolly was right. the problem in local config.
when HTTPD starts as service with boot that is limited environment and correct user required. when i make service restart after boot i logging in and service uses correct user environment and connects to MySQL as that user. so proper configuration of localconfig fixed the problem.
thanks to all of you.

I've been browsing the web and this site from other users which have had this issue and reading the comments to resolve however I've not had much luck and i'm going bonkers trying to work out the issue.
I have two servers - Win Server 2019 and both use XAMPP with Apache and MYSQL, the first server (1) has been running for over a year perfectly fine, however I'm setting up another server (2) to use as a test environment but with a fresh install of windows, xampp along with the Apache/MYSQL modules.
I'm using Invision Community application but I'm getting this upon the first page of installation:
MySQL Requirements
Fatal error: Uncaught mysqli_sql_exception: Access denied for user ''#'localhost' (using password: NO) in C:\xampp\htdocs\ips4.php:317 Stack trace: #0 C:\xampp\htdocs\ips4.php(317): mysqli->__construct('localhost') #1 C:\xampp\htdocs\ips4.php(340): my_mysqli->__construct('localhost') #2 {main} thrown in C:\xampp\htdocs\ips4.php on line 317
IPS4.php is just a file to state whether the server meets all the requirements for the application.
I've then compared MYSQL on (1) to the install on (2) and I've matched the details, given privileges to "root" user on all of the available databases within PHPMYADMIN, granted full grants and then reloaded them, restarted MYSQL and Apache and still same issue.
Normally the Invision software continues through to then request the database details, user details etc. but it hasn't got to that point yet.
The only differences I can see between both servers is (1) is running PHP 7.3.7 | Apache 2.4.39 | MySQL 5.0.12 and server (2) is running PHP 8.2.0 | Apache 2.4.54 | MySQL 8.2.0
I was hoping I would just install XAMPP and then transfer the files to install the software and then configure it to choose which DB/User and then install and get started but apparently not.
ROOT doesn't have a password on (2) but does on (1), when I add a password to (2), I'm then unable to access PHPMYADMIN and doesn't ask for a password to log in. I've spent a few hours today trying to resolve this but now I think I'd like some advice. Many thanks
Setting root password, then flushing privileges, granting full permissions on all databases, copying the mysql files from server (1) to server (2). uninstalling XAMPP and reinstalling.
I don't recall ever needing to do anything for permissions when I setup this software on server (1). I've also installed this software on a few linux servers but didn't enjoy using linux so I stopped using it.
EDIT: It seems it's using MariaDB 10.4.27
Set a password for root on (2).
Change the phpMyAdmin config.inc.php file,change
$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['user'] = '';
$cfg['Servers'][$i]['password'] = '';
then phpMyAdmin will throw a login dialog and ask for a user/password
That should sort out the phpMyAdmin issue.
Big Note: You really should not be using the root account for any app/website access. Instead you should create a user account in MySQL/mariaDB one for each app/website that has access only to the database(s) required for that app/website. (Basic Security)
There was a user called "Any" hostname "%" which looks to be what was causing the issue, I gave it access to all databases (most likely wrong thing to do but it's internally accessed only - no access outside of our network).
This got rid of the error
Thanks for your help
My MySQL Workbench is not connecting to my local host, and I cannot figure out why exactly it is reacting like this. It just started doing this one day, and randomly it will give me access although it says it is still "unknown", but I am tired of this and would like to fix it.
Since this website reqires that I have a "10" reputation to post images, I will have to describe it.
On the Startup/Shutdown tab in the administration page, it says:
The database server instance is unknown. --The "Start Server" button is faded out so that I cannot click it.
Startup Message Log
2013-07-11 08:57:51 - Workbench will use cmd shell commands to start/stop this instance
2013-07-11 08:57:51 - Status check of service 'MySQL' returned error: Not found

2013-07-11 09:02:01 - Status check of service 'MySQL' returned error: Not found
Then on the server status tab in the administration page, it says:
Name: mysqld#localhost
host: localhost
server:unknown
status: unknown
Connection
There is no connection to the MySQL server. This functionality requires an established connection to a running MySQL server to work.
If anyone can help out, that would be great!
Thanks
I had this problem on my Windows 8.1 machine and it turned out to be problems with the file permissions.
To repair it I went into the folder at "C:\Program Files\MySQL\MySQL Server 5.6" and right clicked on the "data" folder and selected properties. Clicked the security tab and clicked edit. From there click the ADD button then the ADVANCED button and finally the FIND NOW button. In mine I added users, administrators, and "ALL APPLICATION PACKAGES". I granted full control to the users that were already listed for the data folder and the users, administrators, and ALL APPLICATION PACKAGES.
After the permissions were repaired I opened a command prompt as administrator and changed to the "C:\Program Files\MySQL\MySQL Server 5.6\bin" directory cd "C:\Program Files\MySQL\MySQL Server 5.6\bin". From there you can execute mysqld --install which installs the MySQL service.
More information about installing the mysql service on windows can be found at http://dev.mysql.com/doc/refman/5.0/en/windows-start-service.html
[edit] Please note that if you are using a different version of MySQL than the path to the MySQL data directory and bin directory may be different on your windows machine.
The error message says it: the service with the name MySQL cannot be found. So probably your MySQL service has a different name? Do you have a service at all? Starting mysql manually from the bin folder is just that: manual. There is no service involved, hence WB cannot manipulate the run state.
When you install MySQL with the MySQL installer you have everything in place within a couple minutes and it works right from the start.
So first check if you have a service running for your MySQL server and stop starting it manually. If there's a service take its name and enter it in the Windows Service Name field of the configuration manager:
Note that MySQL Workbench can manage your server only if it is installed as a Windows service.
I had this problem on my Windows 8.1, and I solved it updating my workbench to Version6 with "mysql-installer-web-community-5.6.16.0.msi" from the official page of mysql
I have found reinstalling all MySQL products a better alternative, because some of the solutions on the internet will make another instance of your mysql server along with mysql56, which might mess things up for a beginner.
Remember to keep database files and configuration undeleted during the reinstallation.
I had problem on MAC.
Please ensure you have installed mysql and its running. Because installing only workbench app, will not install mysql service. First install mysql and run the service.
In my case, I tried with brew
brew install mysql // installing mysql
brew services restart mysql // restart service after installing
mysql --version // check version
I'm running a local copy of WordPress on XAMPP/WinXP for development, but would like to maintain a connection to the remote database. I keep getting "Error establishing database connection" no matter what I try.
On the same PC, I can connect to the remote mySQL DB using any number of mySQL clients, and on the mySQL side, the both the user and the database are set to accept incoming requests from any wildcard domain. I can also easily ping the remote database server from my PC (though I don't know how to do it from WITHIN XAMPP).
Is XAMPP its own little universe that can't reach through to the outside world? Or is there something I'm clearly overlooking that's not letting me connect?

Edit
Thanks to #Michael for suggesting I just create a simple connection script so I can get better insight into the actual error that's being thrown. This revealed that it had to do with the old_password setting in mySQL. See my Answer below for a full description of how to resolve this issue.
Here's the test script I put inside my xampp\htdocs folder and tested out:
<?php
$mysqli = new mysqli('my.server.address', 'user_name', 'password', 'database_name');
if ($mysqli->connect_error){
die ("Connect error: " . $mysqli->connect_error );
}
I'm not really clear on why this became an issue on my XAMPP installation, since I'm also running PHP 5.3.x on the server's local box and wasn't experiencing those issues there. However, it has to do with my mySQL server running in "old password" encryption mode. Newer versions of PHP won't allow those kinds of connections, so you need to update your mySQL server to use the newer password encryption. Here are the steps, assuming you have control over the mySQL server. If you don't, that falls out of the scope of my knowledge.
locate the configuration file for the mysql server called my.cnf. I found mine at /etc/my.cnf. You can edit it with sudo nano /etc/my.cnf
Look for a line that says old_passwords=1 and change that to old_passwords=0. You have now told the server that the next time it is run, and it is asked to encrypt a password using the PASSWORD() command, it use the new 41-character encryption rather than the 16-character 'old' style encryption
Now you have to restart your mysql server / service. YMMV, but on Fedora that was easily done with sudo service mysqld restart. Check your OS' instructions for restarting the mysql daemon or service
Now we have to actually edit our user table within mysql. So open up an interactive shell to mysql (on the server you can type mysql -uYourRootUsername -pYourRootPassword)
Change to the mysql database. This is the database that holds all the good stuff for server operation and authentication. You must have root access to work with this database. If you get an 'access denied' you're SOL. Sorry. use mysql; will switch to that database
Now we want to update the user that was giving you grief. Ultimately you'll probably want to update all your users, but for now, we're just focusing on the user that threw the error. update user set Password=password('YOUR_PASSWORD') where User='YOUR_USERNAME';
Now you just need to tell mysql to use the new password for authentication when that user attempts to connect. flush privileges;.
You should be good to go!
I just installed the latest version of MySQL. Until Now I had it on Windows XP but I wanted to install this on another computer with Windows 7.
Even after configuring everything correctly, the MySQL client won't show up in the Start Folder. So I went to the bin folder of MySQL and tried opening mysql.exe but it would immediately close down.
I then tried opening mysql.exe in cmd & this is what I get
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysql
ERROR 1045 (28000): Access denied for user 'ODBC'#'localhost' (using password: N
O)
Any Ideas how I can get this to work?
Provide username (root)
C:\Program Files\MySQL\MySQL Server 5.5\bin>mysql -uroot
Default passsword is blank, but if you set it, you will need to provde password as well
I don't recall where I first read it, but when facing this problem before, I found that I had to manually turn on a service:
Windows key+R and type Run and hit "enter"
Type "services.msc", hit "OK"
Find "MySQL56", right-click and choose "Start"
You should now be able to log in with no trouble
That's the solution that worked for me; hopefully it helps others out there.
What #Herschel said is right if you follow his steps 1-4 then try to log in with your password in command line you'll have no trouble.
You can also make this run automatically as a service, something which you need when running it on a server.
Open Run
Type "services.msc" click ok
Find the MySQL service
Right-click properties then go down to startup type:
Change it to automatic
I followed these steps and it worked for me:
1. Open Command prompt in admin and go to the location of Mysql bin folder and type -
C:\ProgramFile\mysql\bin>mysql -u root -p <password>
2. Then the prompt asks for the password. This is the password or the root user which
you had set during installation of mysql.
3. Type the password and you will login in to mysql.
4. Also make sure your mysql service is running in the backend by going to the
windows service panel and check whether the mysql service is running.
Heyoo Heyoo. So as of today 19th March 2022 I had this same issue but imma show you how I solved it. My specs before we start:
MySql Version: 8.0
OS: Windows 10
OS Build: 19044.1586
Alright, I'm fairly new to SQL, was following along with a tutorial but when it got to the point of opening the client command line it wouldn't open, it just popped up and closed back; didn't even ask for a password. After watching several tutorials (which were very unhelpful) I noticed from those tutorials that the solution they proffered was to "Active the MYSQL80 service", but that was unhelpful to me because I couldn't see that service in the services menu.
So I decided to go back to the "MySql Installer -Community" App (I installed the community version of SQL)
After the installer had opened up I clicked on the "Reconfigure" action for MySQL Server
It opened the configuration window for the SQL Server and I followed the configuration process to set up the server (turns out I didn't initially set it up when I installed MySQL 😅😅). After the configuration process was done I went back to the services menu to see if the "MYSQL80" service was there... and it was, I checked to see if it was running; following the instructions from this tutorial. After making sure the service was running I went back to the client command line, it finally opened up, allowed me to input my password, and it's working properly!!
I recently installed MySQL 5 on Windows 2003 and tried configuring an instance. Everything worked fine until I got to "Applying Security settings", at which point it gave me the above error (Can't connect to MySQL server on 'localhost' (10061)).
I do have a port 3306 exception in my firewall for 'MySQL Server'.
Got this error on Windows because my mysqld.exe wasn't running.
Ran "C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld" --install from the command line to add it to my services, ran services.msc (start -> run), found the MySQL service and started it.
Didn't have to worry about it from there on out.
To resolve this problem:
go to the task manager
select Services tab
find MySql service
Running
That's all.
You'll probably have to grant 'localhost' privileges to on the table to the user. See the 'GRANT' syntax documentation. Here's an example (from some C source).
"GRANT ALL PRIVILEGES ON %s.* TO '%s'#'localhost' IDENTIFIED BY '%s'";
That's the most common access problem with MySQL.
Other than that, you might check that the user you have defined to create your instance has full privileges, else the user cannot grant privileges.
Also, make sure the mysql service is started.
Make sure you don't have a third party firewall or Internet security service turned on.
Beyond that, there's several pages of the MySQL forum devoted to this:
http://forums.mysql.com/read.php?11,9293,9609#msg-9609
Try reading that.
I had difficulty accessing MySQL while connecting via a localhost connection on the standard port 3306, which worked fine when I installed and configured it for prior classes I had taken in MySQL and Java. I was getting errors like "error 2003" and "Cannot connect to MySql server on localhost (10061)". I tried connecting from both MySQL Workbench (5.2.35 CE) and Netbeans (7.2). I am using Windows 7 64 bit professional.
I tried typing in services.msc in the start menu search box, which opened the services dialog box to show all the services installed in windows. I scrolled down to MySQL and started this service. Subsequent attempts to connect to MySQL from MySQL WorkBench and from the command prompt succeeded.
English:
press Windows + R
write "services.msc". Then press Enter
search for MySQL57 and right click
click on start the service
Français :
Appuyez sur la touche Windows + R
Écrire "services.msc" Puis appuyez sur Entrée
Recherchez MySQL57 et clic droit
Cliquez sur rédémarrer
press Windows key + R
write "services.msc" enter
search for "MYSQL56"
write click on it and start the service
Make sure that your windows host file (located at c://windows/system32/drivers/etc.host) has following line. If not, add it at the end
127.0.0.1 localhost
::1 localhost
Sometimes mysql can not trigger Windows to force start host services if firewall blocks it, so start it manually
win+run>>services.msc, select the "MySQL_xx" where "xx" is the name you have assigned to MySQL host services during setup. Click on 'start' to start from hyperlink appeared on left side.
I tried Kuzhichamadam Inn's solution and found that a slight change needed to be made.
MYSQL57 was a network service. I had tried this repeatedly with no success. When I opened services.msc I found another service for localhost: MySQL. I started that one using the process below and it worked.
run > services.msc > rightclick MySQL > properties >start
I got this error when I ran out of space on my drive.
Go to Run type services.msc. Check whether or not MySQL services are running. If not, start it manually. Once it is started, type MySQL Show to test the service.
To connect locally to MySql, you do not have to setup a firewall with inbound rules. But, even if you already setup iptables to allow the TCP inbound port 3306 and grant the privilege to the user to access the db locally, you may have to setup the bind address in your my.cnf file, edit the default address there and put the server IP address that is running the MySql service.
Since I have struggled and found a slightly different answer here it is:
I recently switched the local (intranet) server at my new workplace. Installed a LAMP; Debian, Apache, MySql, PHP. The users at work connect the server by using the hostname, lets call it "intaserv". I set up everything, got it working but could not connect my MySql remotely whatever I did.
I found my answer after endless tries though. You can only have one bind-address and it cannot be hostname, in my case "intranet".
It has to be an IP-address in eg. "bind-address=192.168.0.50".
run > services.msc > rightclick MySQL57 > properties >set start type option to automatic
after restarting computer
At cmd
cd: C:\
C :\> cd "C:\Program Files\MySQL\MySQL Server 5.7\bin"
it will become
C:\Program Files\MySQL\MySQL Server 5.7\bin>
type mysql -u root -p
ie C:\Program Files\MySQL\MySQL Server 5.7\bin> mysql -u root -p
Enter password: ****
That's all
It will result in
mysql>
Another possibility:
There are two ways the MySQL client can connect to the server: over TCP/IP, or using sockets. It's possible you have your MySQL server configured to support socket connections, but not network connections.
Nothing to do just "Reset to Default" your firewall setting it will start working.
I read many solutions but nothing worked properly, so at last I reset firewall settings which worked.
finally solved this.. try running mysql in xammp. The check box of mysql in xammp should be unclicked. then start it. after that you can open now mysql and it will now connect to the localhost
Edit your 'my-default.ini' file (by default it comes with commented properties)as below ie.
basedir=D:/D_Drive/mysql-5.6.20-win32
datadir=D:/D_Drive/mysql-5.6.20-win32/data
port=8888
There is very good article present that dictates commands to create user, browse tables etc ie.
http://www.ntu.edu.sg/home/ehchua/programming/sql/MySQL_HowTo.html#zz-3.1
I did not have Mysql server installed, that package was missing and I got it from this link https://dev.mysql.com/downloads/installer/
Right click on My Computer
Click on Manage
Go to Services and Application
Select Services and find MySQL service
Right click on MySQL and select Start
