MySQL用户数据库没有密码列-在OSX上安装MySQL
我正在尝试更改MySql根密码。
我所做的如下。
- 安装MySql-5.7.6〜.dmg(社区服务器)和工作台。
- 在OSX系统首选项上关闭服务器。
- 使用控制台访问MySql。该命令是
mysqld_safe --skip-grant
- 执行
update user set password=password('1111') where user='root';
并得到一条错误消息->ERROR 1054 (42S22): Unknown column 'password' in 'field list'
。
仅供参考,我做到了use mysql;
。所以我确实在用户表上选择了查询,发现密码列实际上不存在。
这很奇怪。原始用户表是否可能没有密码列?
如何更改不存在的密码?
谢谢你的回答:D
回答:
在MySQL 5.7中,删除了mysql.user表字段中的password字段,现在该字段名称为’authentication_string’。
首先选择数据库:
mysql>use mysql;
然后显示表格:
mysql>show tables;
您将找到用户表,现在让我们看一下它的字段:

惊喜!没有名为“ password”的字段,密码字段为“ authentication_string”。因此,只需执行以下操作:
update user set authentication_string=password('1111') where user='root';
现在,一切都会好的。
与MySQL 5.6相比,更改非常广泛:MySQL 5.7的新增功能
