mysql ERROR 1045_MySQL

Jun 01, 2016 pm 01:10 PM

C:/Program Files/MySQL/MySQL Server 5.0/bin> mysql -u root -p

Enter password:

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

 

编辑mysql配置文件my.ini(不知道在哪请搜索),在[mysqld]这个条目下加入

  skip-grant-tables

保存退出后重启mysql

1.点击“开始”->“运行”(快捷键Win+R)。

  2.启动:输入 net stop mysql

  3.停止:输入 net start mysql


这时候在cmd里面输入mysql -u root -p就可以不用密码登录了,出现password:的时候直接回车可以进入,不会出现ERROR 1045 (28000),但很多操作都会受限制,因为我们不能grant(没有权限)。按下面的流程走(红色部分为输入部分,粉红色的是执行后显示的代码不用输入):

1.进入mysql数据库:

mysql> use mysql;

Database changed

2.给root用户设置新密码,蓝色部分自己输入:

mysql> update user set password=password("新密码") where user="root";

Query OK, 1 rows affected (0.01 sec)

Rows matched: 1 Changed: 1 Warnings: 0

3.刷新数据库

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

4.退出mysql:

mysql> quit

Bye

改好之后,再修改一下my.ini这个文件,把我们刚才加入的"skip-grant-tables"这行删除,保存退出再重启mysql就可以了。
