将mysql 5.5版本的数据导入mysql 5.7后出现mysql.user表坏掉的情况
出现问题：mysql.user表坏了
root@10.10.10.10 ((none)) > grant all privileges on *.* to 'tmp'@'localhost' identified by 'tmp' with grant option; ERROR 1805 (HY000): Column count of mysql.user is wrong. Expected 45, found 42. The table is probably corrupted Mon Dec 13 17:31:40 2021
解决办法：升级mysql一下：mysql_upgrade
