I am using MAMP 4.1 on Windows 10 and cannot get MySQL server to start. When I uninstalled MAMP and re-installed it MySQL server starts up, but when I stop it, it will not start back up. I also went into the \mamp\db\mysql\ and deleted the four log files hilited below. Then I turned the server off, then back on, but only Apache starts up, not MySQL.
There is also a process running in services called MySQL80. When I try to start it I get the error message shown. I have tried many ways to delete it, including going to the command prompt and using "sc mysql80" and going to 'regedit'. MySQL80 does not show up anywhere so that I can delete it.
Also, the Resource Monitor below shows that Apache is running on port 80, but nothing on port 3306. And yes, my MAMP Preferences are set to port 3306 for MySQL.
When MySQL was running, I had 2 processes of 'mysqld' listening: one session on IPv6 Port 3306, and the other session on IPv4 Port 3306?
What's wrong and how do I fix it?
And, is there suppose to be (2) sessions of 'mysqld' both listening on port 3306 where one is on IPv6 and the other is on IPv4?
Thanks Community.

I had the same problem. I contacted mamp support, and their answer was the following; it worked for me. Hope this helps you too. Stop all servers in MAMP.
The below assumes your MAMP installation directory is C:\MAMP\.
For MAMP:
With Windows Explorer go to folder C:\MAMP\db\mysql\
First backup all files that begin with mysql-bin.*, then delete them (including mysql-bin.index file.)
Then try starting all MAMP servers again (wait for MySQL to turn light on).
After that stop all MAMP servers again.
You'll now try to disable binary log-bin in MAMP (or MAMP PRO)
Open up MySQL configuration file in text editor of your choice: C:\MAMP\conf\mysql\my.ini
Find following text: log-bin
Comment this line by adding # character at start of line.
#log-bin=mysql-bin
Save and restart servers
After that put the mysql-bin.* files back in their place.
Turn off your MAMP Server.
Locate your db folder for mysql. Example: C:\MAMP\db\mysql
Rename the mysql-bin.index file to mysql-bin_old.index (or anything really)
Turn on your MAMP Server
This is a very common issue with MAMP. If this happened to you out of the blue, this is probably the fix.
This is what I did to solve this issue:
Quit MAMP if open
Navigate to /MAMP/tmp/mysql
Rename mysql.sock.lock
Restart MAMP
my issue was Avast Antivirus blocking MAMP, disabled for 10 minutes and Apache started
I had the same problem today.
I did try removing everything from C:\MAMP\db\mysql\ and tried to restart MAMP & servers. But it failed.
Then I noticed the following error in the mysql log file /MAMP/logs/mysql_error_log.err
[error] Cannot open windows event_log ; check privileges
This basically means that you don't have sufficient access.
So
I replaced all the files that I originally deleted
shutdown the server & MAMP.
Now right click on the MAMP icon & choose run as administrator
Now it starts up normally
Uninstall entire MAMP and also any other xamap and wamp if you install previously.
Check the drive C. No any other folder or file related to this present there.
then reinstall MAMP again. All the problems are solve your apache and mysql both start.
please vote me.
This is what worked for me :
Click on Start Servers in MAMP
Manually click on mysql.exe in
MAMP installation folder (C:\MAMP\bin\mysql\bin\mysql.exe)
Tip : You can pin mysql.exe to Start Menu so you don't always have to search for this folder
I sometimes get the databases in phpMyAdmin that are stored under /Library/Application Support/appsolute/db/mysql, this should be the path for MAMP PRO. However, I don't use MAMP PRO. I have tried the trial once, and continued using the free version.
However, sometimes I get the databases visible under /Applications/MAMP/db/mysql, they are a bit off, and I am missing a database there I was working on the other day, but the database is visible in the MAMP Pro database.
I have tried copying the database to the MAMP free database folder, but this results in giving errors in phpMyAdmin. It does show the tables in the database, but it cant display the structure of the tables.
Update:
Still experiencing this issue. Right now I just started my Mac and started MAMP, wanted to continue working on a project and it loads the other database (I think this is the database stored in MAMP Pro), when yesterday it was loading the MAMP databases.
I have no idea how and why this is happening, and how I can find the issue.
Long story short: MAMP uses the MAMP Pro databases sometimes in /Library/Application Support/appsolute/MAMP PRO/db/mysql instead of /Applications/MAMP/db/mysql/, note that I don't have MAMP Pro, I have the regular MAMP. Sometimes it uses the MAMP database folder, sometimes it uses the MAMP Pro databases folder.
MAMP is using this mysql database:
/Applications/MAMP/db/mysql
MAMP PRO is using this databse:
/Library/Application Support/appsolute/MAMP PRO/db/mysql
this may help I'm not too sure - your databases should be in either one
This sounds like a path related issue.
Check your system paths and fix any errors that are pointing to MAMP Pro.
Also, check your MAMP conf file and see how the datadir is set, is it set to the MAMP Pro location ?
SHOW GLOBAL VARIABLES LIKE 'datadir';
datadir - /Library/Application Support/appsolute/MAMP PRO/db/mysql/
An example of a custom conf file used to change this
default-storage-engine=MyISAM
innodb=OFF
datadir=/Users/someuser/drive/mysql/
Let me know in the comments if this helps and we can work out the error as we go along, I'll edit the answer accordingly if need be.
here´s my problem.
I was required to install MySql server as a local process to create a development environment. I use Mac OS X Yosemite. Pretty normal...
But...
After the installation... I noticed that mysqld connects on port 3307 instead of 3306.
I also noticed that I had MAMP previously installed.
So... I removed MAMP (not sure if did it the right way... erased the folder and it´s contents)... Removed MySql (removed all mysql folders on var/local and on /etc)... Removed even Workbench (leap of faith...)
Reinstalled Mysql and........ NOTHING... still connects at 3307..
So I changed my.cnf in /etc... and...... NOTHING again... mysql seems to be ignoring my.cnf...
I´ve searched for all my.cnf files possible... and made sure that the port line is commented on all of then...
Please... I can´t sleep anymore... Help me!!!
I had same problem and i couldn't change mysql ports from configuration files.
SOLUTION :: You should change your launch daemon configurations(or com.oracle.oss.mysql.mysqld.plist) from /Library/LaunchDaemons
MySQL Launch Daemon configuration link
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 tried to use MAMP Pro to replace previous XAMPP on my Mac due to its easy Virtual Hosts management. However after I installed it. The MAMP, basic version works, but the Pro version keeps given me this error message:
The MySQL configuration file my.cnf couldn't be written.
I googled for a while and there are some different solutions, like create my.cnf on /etc/, but none of these works. Also the error log is empty.
Has someone encountered this before? Or does anyone have a clue how could I solve this problem? Thank you!
I just purchased MAMP PRO and I'm having this error as well. Here's what "fixed" it:
Open Terminal and type in sudo killall -9 mysqld. You might see "No matching processes belonging to you were found," which is fine, it means that MySQL was not running.
Now, in Applications, look for the regular MAMP folder. Open MAMP here and click Start Servers
Now open MAMP PRO and the servers should be started
This is just a work-around, it definitely should not require these. At the very least, this should get you up and running.
Contacting support!
File -> Reset to Factory Settings
Possibly a permissions issue, but I wasn't able to resolve it. The above fixed it for me.
uninstall mamp.
remove all files about mamp.
reinstall mamp.
I removed 'my.cnf' from '/etc' directory. Restarted MAMP pro. Started server successfully.....
Your configuration may be wrong.
exp.
sql_mode = STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION # success
or
sql_mode = 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION' # error
