During the final step of the installation of MySQLServer (Apply Configurations), I get a strange error. I can't get it. Here's the Log :

Ok.

回答1:
Just had this same problem, i don't know what caused Database initialization failed. But the error was gone after i did a complete uninstall with 'MySQL Installer - Community', restart my pc and then tried to install mysql server.

Here's what worked for me : I uninstalled everything, re-download the installer, updated it, and it worked finally! Weird error..
回答3:
What seemed to work for us, is during installation, when you are prompted to upgrade your installer, select YES.

I run a development system and beta production system on two separate machines. My production system went down on Sunday/Monday. Ended up doing a full re-install to get it going again. Today my development system went down after a server restart.
I found the last line in the file "my.ini" (located with the data) was causing the error "lower_case_table_names=0.0" is an invalid setting. Changed that to 1 for Windows, and then I was able to restart the server without any other changes. I hate fixes like that, who changed that setting?
