1、错误提示

ERROR 1558 (HY000): Column count of mysql.user is wrong. Expected 43, found 42. Created with MySQL 50560, now running 50645. Please use mysql_upgrade to fix this error.

意思是数据库以前做过升级但是数据库里的mysql库没有升级导致的权限混乱 2、解决办法 升级数据库使用命令 mysql_upgrade -uroot -p ‘密码’

最后一个错误是因为其他的数据库表没法更改，这个不会影响。 到这算是解决上面的错误。权限可以正常使用了
