This post has been deleted.

if you have this problem Access denied for user 'pma'@'localhost' (using password: NO) you can solve it by going to:
1:C:\xampp\phpMyAdmin\config.inc.php
2:search for /* User for advanced features */
3:change pma to root or your username $cfg['Servers'][$i]['controluser'] = 'root'; sorry for my english

Has anybody figured out how to get the stop button working. I even tried "net stop mysql" and couldn't find any service is Windows services. All I could do was shut down the PC and restart it. With errors while shutting down.

@sdbrown67 I just simplified the whole process. Please Update to the latest XAMPP version and try it again. Due to permission problems, the XAMPP control panel could cause problems. This script helped me: https://gist.github.com/odan/eb6dd532a59956f4ae9b1216fa842271

While executing mysql_upgrade.exe -u root -p I got error mysql_upgrade: [ERROR] 1136: Column count doesn't match value count at row 1.
This was solved by adding --force to the upgrade command.
mysql_upgrade.exe -u root -p --force

To stop the mysql service in windows, you can open xampp control panel in administrative mode and stop the mysql service

Does this guide implicitly requires that you have admin privileges before performing? If not, please help because I cannot start my MySQL service after performing the steps above. I got stuck at

Start the MySQL server. You can use the XAMPP Control Panel (MySQL > Start) to start the MySQL service.

I do not need to migrate old data from MariaDB.

I fixed by copying the data directory from mariadb to mysql. I didn't need the old databases so I didn't copy at first. but there must be some things in that mariadb/data that is needed. Anyway it works now it appears.

The reason I changed over to MySQL by Oracle is because MySQL Workbench wouldn't work with MariaDB. I've been using MySQL Workbench for years and love it. I wasn't quite so impressed with MariaDB Workbench looking at it earlier today.

Same error as @devshark above

Thanks for putting this together @odan

ah still not working. MySQL Workbench not liking it. screenshot below ...

thank you so much

@yiiprogrammer @devshark

You can create a fresh data directory with this command:

cd c:\xampp\mysql
c:\xampp\mysql>bin\mysqld.exe --initialize-insecure --basedir=c:\xampp\mysql --datadir=c:\xampp\mysql\data

May be useful to include a link to https://github.com/phpmyadmin/phpmyadmin/blob/master/sql/create_tables.sql

If the user decides against importing their old data, their phpmyadmin will break unless they run the above script :)

I think you miss one folder (\bin) on the route
Create a new file: c:\xampp\mysql\my.ini and copy this content:

It should be
Create a new file: c:\xampp\mysql\bin\my.ini and copy this content:

I cant start mysql from xampp

@akaki1991

Make sure you have installed the 32-bit version of MySQL. The 64-bit version is not compatible with the XAMPP Control Panel.

my.ini needs to be in /bin unlike original instructions - otherwise works
thanks @addylov89 for pointing that out

Thank you for the tut, it helped me a lot. About the start/stop issue, @addylov89 solves it.

Worked like charm. Replaced MariaDB 10.1.34 with MySQL 5.6.41.
Now MySQL Workbench works well with MySQL on XAMPP.
Thanks

my.ini should be in the bin directory

Yes move my.ini should be in the bin directory
Work now

Worked like a charm. Cheers guys. my.ini does need to be in the bin directory, indeed.

The MySQL server should be restarted after the mysql_upgrade.exe command, otherwise there might be errors.

See: https://stackoverflow.com/questions/6288103/native-table-performance-schema-has-the-wrong-structure

Is it possible to do the same for mac OS?

Hello @odan, i faced mysqld.exe - System error.

The code execution cannot proceed because msvcr120.dll was not found. Reinstalling the program may fix this problem.
Please help me.

Thank you.

@akaki1991

Make sure you have installed the 32-bit version of MySQL. The 64-bit version is not compatible with the XAMPP Control Panel.

Worst news :(
Btw, would be great to see in the https://odan.github.io/2019/11/17/xampp-replacing-mariadb-with-mysql-8.html description
This answer sold my problem 👍

I have followed all the steps its still not working,

The code execution cannot proceed because msvcr120.dll was not found. Reinstalling the program may fix this problem.

installed the 32 bit updated my.ini

@loyison The file MSVCR120.dll should be part of the Microsoft Visual C++ 2013 Redistributable Package

Links aren't working anymore

Bad... The links are broken... maybe Takedown?
