Windows 10

I'm sorry that I created the process twice.

Yes, it is correct that mysqld.exe is small. But , it uses server.dll , which is big

The hint with the server.dll was crucial
I did not copy the file.

I always use the ZIP file and manually copy the necessary files.

What other files must be in the BIN folder?

It runs. thank you

Stefan.

Hi,

I have to revise myself. It runs on one computer, but not on another. There I get the error message 1067

Stefan

mysqld.exe, and server.dll and it should run on Windows 10.
1067 is catch-all message, nothing telling.

please run "mysqld --help" on the commandline, maybe it will tell you what's up.

mysqld --help doesn't report (Result 01.txt)
Maybe you can do something (Result_02.txt) with mysqld --help --verbose?

ok , so mysqld can start.

But if the server does not startup, you'd have to provide error log. or Windows event log, the Application\MariaDB entries.

My crystal ball says that perhaps, you did not stop server with --innodb-fast-shutdown=0 previously. Therefore it does not come up. But it can be wrong.

I tried on several computers. The same is happening everywhere.

I have added an extract from the event log below:

Name der fehlerhaften Anwendung: mysqld.exe, Version: 10.5.4.0, Zeitstempel: 0x5ef224e3
Name des fehlerhaften Moduls: ucrtbase.dll, Version: 10.0.19041.1, Zeitstempel: 0xbd1e2564

Pfad der fehlerhaften Anwendung: d:\Programme\MySQL\bin\mysqld.exe
Pfad des fehlerhaften Moduls: C:\WINDOWS\System32\ucrtbase.dll

I'd rather had the error log with full info, but the crystal call tells me you were using deprecated
mysqld --install <service_name> , not the blessed mysql_install_db.exe

This is broken in 10.5.4, and corrected later. https://jira.mariadb.org/browse/MDEV-23038 has details, and workaround

I'm closing this, because of strong suspicion of the duplicate. If there was anything else please provide a reproducible test case.
