mysql ERROR 1045_MySQL
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。
