[solved]#1449 – The user specified as a definer (‘mysql.infoschema’@’localhost’) does not exist

I updated the mysql from 5.0 to mysql 8.0 today, everything seemed smooth before I restarted the server, I changed the “nginx 301 https”, then restarted the service, I got this error:

Then I login the mysql, I got this error:

Error 1449 - The user specified as a definer ('mysql.infoschema'@'localhost') does not exist

Error #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') ORDER BY `User` ASC, `Host` ASC' at line 1

I checked all the solutions on the internet, and I used the following solution, but this idea wasn’t work on me,

you can check the original page here.

mysql -u root -p
drop user  `mysql.infoschema`@"localhost";
flush privileges;
create user `mysql.infoschema`@"localhost" identified by '123456';
flush privileges;
use mysql;
update user set Select_priv = 'Y' where User = 'mysql.infoschema';
flush privileges;

And I got another error:

ERROR 1726 (HY000): Storage engine 'MyISAM' does not support system tables. in Mysql 8.0 after CREATE USER

Finally, I changed the my.cnf to got both errors solved.

vim /etc/my.cnf  
service mysqld restart 

You can open your Winscp, open and edit the my.cnf here: /etc/my.cnf

Restart the service or server, it works!
