My Wamp Server was working perfectly well until yesterday when I started the mysqld from the command line and went on to import a .sql file from the MySQL console. The WAMP icon stays orange all the time. There is no issue with the Apache service but the issue is with the MySQL service. When I looked for wampmysqld service on services.msc, it doesn't show any. But when I run mysqld from the command line, it works fine.
Itried several methods but none of them worked. I also tried installing Wamp Server 2 as an addon but it didn't work for me, and now I can't select the version of MySQL even.
Can anyone please help me out?
It sounds like you have 2 MYSQL Servers running.
Check the Event Viewer for messages from MYSQL.
Check the services, wampservers MYSQL is called wampmysqld64, if you have another running it will probably be called MYSQL
If this is the case, you will either have to uninstall the other MYSQL or at least Stop it in the services snapin, or disable it, if you are sure it was a mistake uninstall whatever brought this other MYSQL to your party
What did you install recently, some apps bring their own mysql instance for example some installs of MySQL Workbench will install an instance if you pick the full with everything version.
My problem is that windows services don't have MySQL Server. How to run it?
I need to run MySQL Server on a new for me laptop. There's Windows 7. And MySQL have been installed on it. In order to verify this, I opened the Programs and Features window and saw it there:
But when I go to the Services to run it, I don't find it. It's absent there:
It's very strange for me. Why MySQL is not among the services? How can I run it? It's installed on this station.
Try performing the following steps and then check again.
Start Command Prompt (cmd)
Go to the "C:\Program Files\MySQL\MySQL Server 5.6\bin"
type mysqld --install
In my case I installed it through XAMPP so I do not have it among windows services (it has it´s own control panel), but I found this document that may help you solve this problem:
https://dev.mysql.com/doc/refman/5.1/en/windows-start-service.html
Also check the error log file which shows specific information about the start and stop of the service. In my case is called mysql_error.log and it is located under the '...mysql\data\' folder. Another document talking about that:
https://dev.mysql.com/doc/refman/5.7/en/error-log.html
I've just installed XAMPP for Windows - should be the newest version (XAMPP Control Panel v3.2.1).
Apache is running just fine on port 80 and 443, but MySQL is not starting. When I press the start button, I get this message:
Attempting to start MySQL service...
Then a window pops up and asks me if I want to allow this, which I want. But nothing happens after that. I can press as many times as I want, but with the same result.
What can I do with MySQL?
If you have MySQL already installed on your windows then go to services.msc file on your windows and right click the MySQL file and stop the service, now open your XAMPP and start MySQL. Now MySQL will start on the port 3306.
I had an issue with this because I had accidentally installed XAMPP to c:\windows\program files (x86) which caused a Windows permissions issue.
The installation says not to install it there, but I thought it had said to install it there.
I uninstalled and reinstalled to c:\xampp and it worked.
After Stop xampp, go to configure and change the port 3306 to 3308 of mysql and save. Now start the sql......Enjoy
In the cmd type: services.msc Find MySql and change properties to the disabled.
In the control panel of Xampp uninstall MySql by the checkbox on the left side, and install again by the click in the same checkbox.
Windows 10 Users:
I had this issue too. A little bit of investigating helped out though. I had a problem before this one, that 3306 was being used. So what I found out was that port 3306 was being used by another program. Specifically a JDBC program I was trying to learn and I had xammp installed before I tried this JDBC out. So I deleted the whole file and then here I am, where you're at. The issue was that my 'ImagePath'(registry variable) was changed upon installing mySql again. To put it simply, xammp doesn't know where your mysqld.exe is at anymore, or the file is not in the location that you told it to be. Here's how to fix it:
Open run (Win + r) and type 'regedit'. This is where you edit your registry.
Navigate to: HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > MySql
Click on mySql and notice the ImagePath variable. Right click 'ImagePath' and click modify.
Enter the location of your xammp mySqld file (navigate through xammp to find it) Although it is likely the same as mine.

One of many reasons is xampp cannot start MySQL service by itself. Everything you need to do is run mySQL service manually.
First, make sure that 'mysqld.exe' is not running, if have, end it. (go to Task Manager > Progresses Tab > right click 'mysqld.exe' > end task)
Open your services.msc by Run (press 'Window + R') > services.msc or 0n your XAMPP ControlPanel, click 'Services' button.
Find 'MySQL' service, right click and run it.
Only stop My sql In Xampp For 15 Min After 15 min restart Mysql .If my sql running But Port Not Showing in Xampp then Click Config > my.ini edit this file and change port no 3306 > 3307 and save and Restart xampp .........
Only for windows
I have fixed the mysql startup issue by following below steps
Steps:
Open CMD and copy paste the command netstat -ano | findstr 3306
If you get any result for command then the Port 3306 is active
Now we want to kill the active port(3306), so now open powershell and paste the command
Stop-Process -Id (Get-NetTCPConnection -LocalPort 3306).OwningProcess -Force
Where 3306 is active port. Now port will be inactive
Start Mysql service from Xampp which will work fine now
Note: This works only if the port 3306 is in active state. If you didn't get any result from step 1 this method is not applicable. There could be some other errors
For other ports change 3306 to "Required port"
Ways to open CMD and Powershell
For CMD-> search for cmd from start menu
For Powershell-> search for powershell from start menu
Had this problem today, on a Windows 10 machine. Opened C:\xampp\data\mysql_error.log and looked for lines containing [ERROR].
Last error line was:
... [ERROR] InnoDB: File (unknown): 'close' returned OS error 206. Cannot continue operation
Important note: if your error is different, google it (you'll likely find a fix).
Searching for the above error, found this thread on Apache Friends Support Forum, which led me to the fix:
Open C:\xampp\mysql\bin\my.ini and add the following line towards the end of [mysqld] section (above the line containing ## UTF 8 Settings):
innodb_flush_method=normal
Restart MySQL service. Should run just fine.
Did you use the default installation path?
In my case, when i ran mysql_start.bat I got the following error:
Can`t find messagefile 'D:\xampp\mysql\share\errmsg.sys'
I moved my xampp folder to the root of the drive and it started working.
Hope it helps
If you have other testing applications like SQL web batch etc, uninstall them because they are running in port 3306.
I have the same problem. Finally found the solution:
The Relocate XAMPP option in the setup tool didn't correctly relocate the paths and corrupted them, I've manually changed the directories inside my.ini (base dir, data dir , ...). After that mysql started successfully.
The problem I had was changing the path of the Xammp folder in the system.
I can share how I solved the problem in my case.
It seems that somehow I had mySQL Server 5.7 installed. It didn't show on Add/Remove Programs list in Windows tough so I wasn't aware of it. I marked that after I looked up the XAMPP log.
Just after XAMPP launched it has shown in the log that there is a conflict in mySQL and indicated the folder where my mySQL Server 5.7 is installed. I removed mySQL 5.7 manually from Program Files (x86) and ProgramData folder, restarted and XAMPP mySQL started normally then.
I've tried only stopping the mySQL service but for me it didn't work. Only manually deleting all mySQL 5.7 folders seemed to have helped.
Everytime my MySQL starts, it will stop, then I noticed that some files are getting generated in C:\xampp\mysql\data. I tried deleting some files (like the Error logs, err file, etc.) on that directory. Back up first what you're going to delete to avoid losing data.
I don't know how it works. I'm just trying to enable HTTPS in my local machine but then suddenly MySQL can't be started. But now it's working.
I'm using Windows 10 and XAMPP 3.2.4.
This worked for me.
Search for Services in Windows Start
Find MySQL in it.
Right Click and Stop MySQL. Would work on XAMPP Now.
Note: If you wanna use the MYSQL prompt again, you will have to start the MYSQL from Service again.
In my case I had xampp installed with PHP 7.4.
But I needed PHP 8.
I downloaded xampp with PHP 8.
Installed it to C:/xampp8/ folder. When I started the new version, it started successfully.
But then I realized that I needed the database data from the old xampp installation. I stopped the new xampp(php 8 version) , and tried to start xampp (php 7.4 version) and saw that Apache started and was working fine, but mysql was not starting.
I tried many settings but couldn't start mysql from the old xampp.
Solution in my case to copy the data to the new xampp
I went to C:/xampp_old/mysql/data folder. And saw that each of my database has a separate folder inside data folder. I copied all the folders and pasted into
C:/xampp8/mysql/data/
Then I started new xampp and looked in phpmyadmin via browser and I got all my databases back.
In the xampp control panel, to the left of "MySQL" there is a green checkbox, click it to uninstall MySQL service. After that you can start MySQL from the same control panel. You can install those services again, it will still work.
What worked for me was to run xampp "as administrator". Fixed.
I solved this problem by removing all the information in the path
C:\xampp\mysql\data
And copy the information inside this path
C:\xampp\mysql\backup
In Windows, you should go: Start > Run > services.msc > Apache 2.4 > Properties > Start Mode > Automatic > Apply > Start > OK > [Same as MySQL]
if all solutions up did not work for you, make sure the service is running and not set to Disabled!
Go to Services from Control panel and open Services,
Search for Apache2.4 and mysql then switch it to enabled, in the column of status it should be switched to Running
I used to work with XAMPP to build PHP applications. Once I tried Zend engine and uninstalled it. After that, MySQL in XAMPP is not working. It is giving "Terminating worker thread 1" error.
When I check ports,
MySQL has status Service: MySQL_ZendServer51.
Pleas help me how to reassign it back to XAMPP? I have reinstalled XAMPP several times. But no use.
Thanks,
Raj
First you should delete the old mysql service.
Assuming you have Vista or Windows 7:
Go to Start and type cmd.exe in the search field and hit Ctrl+Alt+Enter. This will start the command line as Administrator.
Now you can type sc.exe delete MySQL_ZendServer51 to remove the service.
Now you can start your XAMPP Control Panel and uncheck the "svc" checkbox next to MySQL (if it's not already)
Next check it on again (this will install the proper mysql service)
And make sure you don't have to server running (which could be possible, that Zend installed it's own mysql but for some reason didn't removed it?)
I just went here: c:\xampp\mysql\bin\mysqld.exe
And opened the document and MySQL Started without problem.
I am trying to run MySql 5.1 on Windows 7 Home Premium 64 bit. I have downloaded the MSI installer from the MYSql website and installed it. The installation is successful, but the service does not start.
If I try to run MySql manually using the mysqld executable, it crashes immediately on running (error: mysqld.exe has stopped working).
Earlier mysql was running on the machine, but I had some problem with it (wasn't executing big queries) and installed it again which somehow broke the program. I had installed it to work as a service which started giving me this isse, and now it won't work even if I don't install it as a service.
I have tried removing the mysql folder and re-installing. Is there somewhere else where Mysql saves configuration info or other data?
Has anyone else found this problem and solved it?
How can I find out why the process is failing to run?
Or you can try and run the mysqld.exe as administrator.
See the Debugging a MySQL Server in your MySQL reference manual.
download the noinstall (zip archive) version of MySQL corresponding exactly to the version that is already installed on your system
extract the .pdb symbols files to your existing MySQL installation's bin directory
start Dr. Watson
start mysqld-debug in standalone mode
capture the list of all moduled (i.e. loaded DLLs) with their full path from DrWatson
capture the stack trace from DrWatson
examine the MySQL log files (including mysqld.trace) to see what went on immediately prior to the crash
