  • MySQL ERROR 3009 (HY000): Column count of mysql.user is wrong. Expected 45, found 42. Created with MySQL 50560, now running 50729. Please use mysql_upgrade to fix this error.

    1.产生原因

    在卸载原有的mysql5.5之后,安装了mysql5.7,进入数据库后,我发现原有的数据库都还在,但是在创建用户的时候报错

    ERROR 3009 (HY000): Column count of mysql.user is wrong. Expected 45, found 42. Created with MySQL 50560, now running 50729. Please use mysql_upgrade to fix this error.

     原因:错误是由于你曾经升级过数据库,升级完后没有使用 mysql_upgrade升级数据结构造成的。

    解决办法:更新数据库

     mysql_upgrade -uroot -p
    

     

     然后进入数据库,执行语句

    这次没有报错
