centos 上安装mysql密码修改后还是不能连接出现错误:ERROR 1142 (42000): SELECT command denied to user ''@'localhost' for table 'user' 解决方法: 1.退出mysql mysql> quit; Bye 2.执行下面语句 [root@localhost 桌面]# mysqld_safe --skip-grant-table 3.删除空用户 mysql -uroot mysql delete from
注:有时候修改mysql密码会出现如下状况:密码改了,但新密码就是进不进去. 原因大概是语法错误.例如: >update user set password='hooray' where user='root'; >flush privileges; >Quit: 结果是用新旧密码都进不去,所以修改密码时注意语法!!!
问题描述: Your password has expired. To log in you must change it using a client that supports expired passwords. 原因描述: mysql密码过期了,需要重新设置密码 解决方法: 对于window安装的wampserver来说,它集成了mysql,php,apache,所以需要找到wampserver安装目录下的mysql文件夹,进入mysql的bin目录后,输入 mysql -hlocalh
