i cannot install mysql plugin keyring_file.dll
The reason for that error is that mysql can't locate the keyring_file.dll file.

To fix that do the ff:


Edit the my.ini file located in C:\ProgramData\MySQL\MySQL Server 5.7\ and add the ff in the [mysqld] block:  

early-plugin-load=keyring_file.dll
keyring_file_data=C:/Program Files/MySQL/MySQL Server 5.7/lib/plugin/keyring_file



Restart the MySQL service:  

net stop MySQL57
net start MySQL57

Validate that the keyring plugin is now active: 

SELECT PLUGIN_NAME, PLUGIN_STATUS FROM INFORMATION_SCHEMA.PLUGINS WHERE PLUGIN_NAME LIKE 'keyring%';
