错误问题的描述：

![format_png][]

ERROR 1045 (28000): Access denied for user 'ODBC'@'localhost' (using password: NO)

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

windows下，以上两个错误的解决方法

**解决方法：**

1、找到配置文件my.ini ，然后将其打开，可以选择用NotePadd++打开

2、打开后，搜索mysqld关键字

找到后，在mysqld下面添加skip-grant-tables，保存退出。

PS：若提示不让保存时，可以将该文件剪切到桌面，更改保存后再复制到mySQL目录下

\[mysqld\]  
skip-grant-tables

\# Remove leading \# and set to the amount of RAM for the most important data  
\# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.  
\# innodb\_buffer\_pool\_size = 128M

\# Remove leading \# to turn on a very important data integrity option: logging  
\# changes to the binary log between backups.  
\# log\_bin

\# These are commonly set, remove the \# and set as required.  
basedir = D:\\SoftWare\\MySQL\\mysql-5.7.11-winx64  
datadir = D:\\SoftWare\\MySQL\\mysql-5.7.11-winx64\\Data  
port = 3306  
\# server\_id = .....

\# Remove leading \# to set options mainly useful for reporting servers.  
\# The server defaults are faster for transactions and fast SELECTs.  
\# Adjust sizes as needed, experiment to find the optimal values.  
\# join\_buffer\_size = 128M  
\# sort\_buffer\_size = 2M  
\# read\_rnd\_buffer\_size = 2M

sql\_mode=NO\_ENGINE\_SUBSTITUTION,STRICT\_TRANS\_TABLES

这样，是用于跳过密码问题，但是呢，这并不能彻底解决！

3、重启mysql服务

在任何路径目录下，都可以关闭/重启mysql的服务呢。（因为，之前，已经配置全局的环境变量了）

net stop mysql

net start mysql

4、进入数据库，重设置密码。

mysql -u root -p Enter

不用管password Enter

![format_png 5][]

mysql> use mysql; Enter

mysql> update mysql.user set authentication\_string=password('rootroot') where user='root'; （密码自己设）

![format_png 6][]

mysql> flush privileges; 刷新数据库

mysql> quit;

5、密码重设置成功，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服务就可以了。

6、重启mysql服务，并登录mysql用户，用户是root，密码是rootroot。

![format_png 10][]

D:\\SoftWare\\MySQL\\mysql-5.7.11-winx64\\bin> net stop mysql

D:\\SoftWare\\MySQL\\mysql-5.7.11-winx64\\bin> net start mysql

D:\\SoftWare\\MySQL\\mysql-5.7.11-winx64\\bin>mysql -u root -p

Enter password:rootroot
