mysql5.7修改密码password字段变成了authentication_string字段 - mysql常见问题

一、mysql5.7 开始新版的mysql数据库下的user表中已经没有password字段了保持密码的字段变成了authentication_string字段

如下：

mysql> update user set authentication_string=password('123456') where user='root';

Query OK, 4 rows affected, 1 warning (0.01 sec)

mysql> flush privileges;

修改完毕。重启mysql

二、登录mysql

修改完之后

mysql -uroot -p123456;登录失败

mysql -h127.0.0.1 -uroot -p123456;登录成功

mysql -hlocalhost -uroot -p123456;登录失败

如果不觉得麻烦，你可以针对host=localhost 的账号在修改一次密码

1、[root@localhost /]# mysql -uroot -p123456;

mysql: [Warning] Using a password on the command line interface can be insecure.

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

发现失败

2、[root@localhost /]# mysql -h127.0.0.1 -uroot -p123456;

mysql: [Warning] Using a password on the command line interface can be insecure.
