merhaba centos 7 sunucum var lamp kurduktan sonra
plesk kurarken şöyle bir hata ile karşılaştım sorunun ne olduğunu çözemedim yardımcı olurmusunuz.

ssh de verdiği hata mesajı
ERROR 1396 (HY000) at line 1: Operation CREATE USER failed for 'admin'@'localhost'

ERROR while trying to create 'admin' MySQL user.
Plesk has been able to successfully connect to MySQL server,
but assigning password and privileges to the new user failed.
If you are installing Plesk on an already configured MySQL server with enabled
password strength validation, you may need to disable it for the initial Plesk
installation. After the installation is finished, you may re-enable it.

Check the error reason (see log file: /var/log/plesk/install/plesk_18.0.21_installation.log), fix and try again
