Answer 1

Resolved following these steps:

Answer 2

This is a Bug in the Installer of 8.0.11. There are changes in the lower_case_table_names variable in the new release. See:

https://dev.mysql.com/doc/relnotes/mysql/8.0/en/news-8-0-11.html

Nobody can fix this. If you installing the Server the configfile is write before new. Every time. So if you fix this 0.0 to 0 in my.ini the changes will be overwritten.

Somebody have to report a this bug to MySql.

EDIT: I have report a bug to oracle: https://bugs.mysql.com/bug.php?id=91539

Answer 3

The only way to get rid of this error is by allowing MySQL Installer to update when it prompts to do so at the beginning of the installation. Please note that you will get this error if you didn't allow the installer to update.

Updating lower_case_table_names = 0 in my.ini doesn't fix this because MySql will re-initialize it to 0.0 everytime before running the scripts.

If you didn't allow updates, you will need to uninstall all components of MySql and run the installer again and let it update.

Answer 4

Update the installer for mysql-installer-web-community-5.7.22.1 file during the installation from the web . I encountered the same problem, after updating the installer it works correctly.

Answer 5

When I downgrade MySQL from 8.0.11 to 5.7.22, I encountered this error. Spend a lot of time to fix the bug. Finally, I fix this problem by the following steps:

1. uninstall all the related features with MySql( use Control Panel > Programs and Features)
2. go to C: drive, make all hidden files visible(view > hidden items), find ProgramData file
3. delete the MySql file inside hidden ProgramData file manually. Make sure all the MySQL files are deleted, reinstall MySQL. It works for me. I successfully installed MySQL 5.7.22 without any problem.

My Guess: This error probably will happen if you are second or third time to install MySql server. It seems like the error happens because the old MySql files are not deleted completely. Usually, we all think that after we uninstall the application, the files are deleted from program files, it is clean, everything was done. However, there still some files hidden from us. We have to delete them by ourselves.

Answer 6

On bug page, last comment states that the latest installer solves this problem. For me not. The following steps made me a clean install (after get the latest installer):

When it fails on database initialization step just cancel it back to the installer's main page where you can see installed MySQL server with a reconfigure option.

Now edit the my.ini and set the

"lower_case_table_names=0.0"

to

"lower_case_table_names=0"

Click on reconfigure and now it goes over on this problem.

Hope it helps.

Answer 7

I faced the same problem with 1.4.25 installer and resolved that by doing the following steps [without updating the installer]

1. There is a folder MySQL Installer for Windows\\Manifest\\Templates
2. In Templates folder there are few text files which are there to be used as a template during my.ini generation. I have commented out the line lower_case_table_names=

Now I execute the configuration process using installer and it executes without any error.Also I add the variable later and restart the server.

Answer 8

由于https://bugs.mysql.com/bug.php?id=91476 中报告的错误，将 MySQL 安装程序升级到 1.4.26.0 并重新安装 MySQL 服务器将解决该问题。

Answer 9

When I installed mysql server, wizard of installation was stooped at the point initializing database (if necessary) for that I did.

1. remove mysql folder from 'C:\\ProgramData' folder. Note: ProgramData is hidden. You need to make it visible.
2. Uninstall mysql server if it was in the list of installed programs in control panel.
3. Download mysql-installer-web-community-8.0.13.0 and install it again.

Answer 10

First you have to uninstall mysql:

Step 1. control panel->programs and then uninstall whole mysql.

Step 2. delete folder MySQL from the following path.

1. C:\\Program Files\\MySQL
2. C:\\Program Files (x86)\\MySQL
3. C:\\ProgramData\\MySQL (your programdata folder is hidden so you have to unhide from c drive->views->options->view ->show hidden files) 4.C:\\Users\\hp(your pc name)\\AppData\\Roaming\\MySQL

Step 3. windows+r write regedit.exe enter and follow the path and delete mysql Computer\\HKEY_LOCAL_MACHINE\\SYSTEM\\ControlSet001\\Services\\

Step 4. control panel->administrative tool->services then find mysql copy name then open cmd run as administrative write (sc Delete "mysql name that you copied")enter.

Now you can install MySQL

Answer 11

I had the same problem, tried to change my.ini did't work, so I uninstalled the SQL server, then I google my operating system + Install MySQL videos (In my case "Install MySQL on Windows 8"), then I installed MySQL 5.6.26 then worked. I think the newer MySQL doesn't support certain old operating system.
