Mysql:访问被拒绝用户'root'@'localhost'

标签: mysql

我知道,这真的很难过,但我无法连接到MySQL数据库。

我只是从MySQL站点下载并解压缩了mysql-5.6.10-win32.zip。

我关注this tutorial,但我无法以root身份连接到我的MySQL数据库。

我知道在没有密码的情况下以root身份连接是不安全的,但我只需要做一些测试,所以我现在可以这样做(如果我知道如何以root身份连接我知道如何另外添加另一个用户。)

的my.ini

# For advice on how to change settings please see

# *** DO NOT EDIT THIS FILE. It's a template which will be copied to the

[mysqld]

# 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=c:\Programs\mysql-5.6.10-win32
datadir=c:\Programs\mysql-5.6.10-win32\data

server_id=1


# 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 

[client]

port=3306

当我开始mysqld时,我看到:

set_root_password.sql包含我在How to reset root password中找到的一些命令,以及我希望他们帮助的其他命令:

UPDATE mysql.user SET Password=PASSWORD('pass') WHERE User='root';
grant all privileges on *.* to 'root'@'%';
grant all privileges on *.* to 'root'@'localhost';
grant all privileges on *.* to 'root@localhost';

SHOW GRANTS FOR 'root'@'%';

FLUSH PRIVILEGES;

但我无法登录。

要登录我试过:

>mysql -u root
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)

>mysql -u root --password=pass
Warning: Using a password on the command line interface can be insecure.
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

>mysql

>mysql -u root --password=
Warning: Using a password on the command line interface can be insecure.

>mysql -u root --password=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)

>mysql -u root mysql

>mysqladmin --no-defaults -u root version
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'

在一些教程中,我读到了mysqladmin命令,但它也需要root密码。

我也尝试将密码和mysql作为默认密码清空,没有任何问题。

我也尝试--skip-grant-tables但没有成功。

我在MySQL主目录的bin目录中没有mysqld_safe,所以我无法尝试。

我试着阅读与此问题相关的所有问题,但我不知道我还能尝试什么......

我很沮丧为什么它不像“下载和运行”那么简单。我不想下载Win安装程序,因为我不希望在Windows启动时启动服务,并且在我的系统中没有控制地复制其他东西......

我刚刚发现,我必须连接指定-h和我的PC名称ipconfig -all

>ipconfig -all

Windows IP Configuration

   Host Name . . . . . . . . . . . . : PC1234
   Primary Dns Suffix  . . . . . . . :
   Node Type . . . . . . . . . . . . : Hybrid
   IP Routing Enabled. . . . . . . . : No
   WINS Proxy Enabled. . . . . . . . : No
   DNS Suffix Search List. . . . . . : tmdev

mysql -u root -h PC1234 --password=pass

工作正常。感谢帮助。这很奇怪,但它现在正在运作。

修改

我遇到连接该配置的问题。我通过在my.ini中指定bind-address来解决它:

bind-address=localhost
