How to fix ERROR 1726 (HY000): Storage engine 'MyISAM' does not support system tables. in Mysql 8.0 after CREATE USER
问题 I have an installation of Debian Stretch and a new installation of Mysql 8.0 (no changes in configuration yet). When I try to create a new user with: mysql> CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'xyz'; I got the following: ERROR 1726 (HY000): Storage engine 'MyISAM' does not support system tables. [mysql.db] Any suggestion about what the problem could be? Thank you 回答1: I had restored a DB backup into my new dev MySQL 8 system without thinking and overwrote the MySQL database tables.
