mysql密码算法的不同导致错误，做如下修改： mysql> SET PASSWORD FOR     -> 'some_user'@'some_host' = OLD_PASSWORD('newpwd');

[fb8206320]

不好意思我是新手，

[御命丹心君奉天]

update mysql.user set password = old_password('newpwd') where host = 'localhost' and user = 'root'; 然后flush priviledges; 重新登录

[fb8206320]

ERROR 1046 (3D000): No database selected 又提示这个咋个整呢，是我那个参数改对哇？

引用 3 楼 long_539437 的回复:

update mysql.user set password = old_password('newpwd') where host = 'localhost' and user = 'root'; 然后flush priviledges; 重新登录

那个host 那个参数是啥子意思呢？有点没搞懂

我重新安装了下mysql 重新配置了密码，之前是最新的密码字段不一样。现在可以。谢谢了。
