mysql出现 Unknown column 'Password' in 'field list'

linux安装了mysql之后初始化密码获取:出现了下面的内容,密码很尴尬,无法用root登录:

1 grep 'temporary password' /var/log/mysqld.log
[Note] A temporary password is generated for root@localhost: 4)ZqW0IooQ(a

  出错如下:

[root@iZuf655czz7lmtn8v15tsjZ mysql]# mysql -uroot -p 4)ZqW0IooQ(a
-bash: syntax error near unexpected token `)'

  百度一番找到直接修改登录方式,无密码登录,修改密码:

1、执行以下命令

vi /etc/my.cnf

2、找[mysqld],在下面添加如下内容:

[mysqld] 
skip-grant-tables

3、重启mysql:

service mysqld restart

4、无密码登录mysql

[root@iZuf655czz7lmtn8v15tsjZ mysql]# mysql -uroot -p
Enter password:

5、执行以下命令,本以为顺风顺水,然鹅。。。

update mysql.user set Password=PASSWORD('123456') where USER='root';

  。。。

ERROR 1054 (42S22): Unknown column 'Password' in 'field list'

6、看下这个 mysql.user 表里是些啥。。。

select * from mysql.user;

看来看去就这个列名顺眼: 

 

于是我改了下语句:

mysql> update mysql.user set authentication_string=PASSWORD('123456') where USER='root';
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 1

  。。。wtf(原来,mysql5.7更改密码应该采用命令ALTER USER 'root'@'localhost'IDENTIFIED BY '********'其中密码的命名规则有所改变:MySQL 设置的密码中必须至少包含一个大写字母、一个小写字母、一个特殊符号、一个数字,密码长度至少为8位

7、好在改完了,接下来执行回退,回到/etc/my.cnf中删除新增的skip-grant-tables重启即可
