MySQL error 1558 (HY000): column count of mysql.user is wrong

1. The following error was reported when creating database with MySQL today:

mysql> CREATE USER 'dev'@'%' IDENTIFIED BY '123456'; 
ERROR 1558 (HY000): Column count of mysql.user is wrong. Expected 43, found 42. Created with MySQL 50560, now running 50643. Please use mysql_upgrade to fix this error.

2. Solutions

The main reason for this error is that I upgraded the database and did not use it. Just use the following command:

[[email protected] ~]# mysql_upgrade -u root -p
