我一直在按照手册在Ubuntu上安装软件套件。我完全不了解MySQL。我已经在我的Ubuntu上完成了以下安装。

sudo apt-get update
sudo apt-get install mysql-server-5.5
sudo apt-get install mysql-client-5.5
sudo apt-get install mysql-common
sudo apt-get install glade
sudo apt-get install ntp

然后我做了

cd ~/Desktop/iPDC-v1.3.1/DBServer-1.1
mysql -uroot -proot <"Db.sql"

我最终得到以下错误消息。

错误1045(28000):拒绝访问用户'root'@'localhost'(使用密码:YES)

我该如何修复它并继续?


当前回答

我以root用户($SUDO)安装MySQL,得到了同样的问题

以下是我的解决方法:

sudo cat /etc/mysql/debian.cnf This will show details as: # Automatically generated for Debian scripts. DO NOT TOUCH! [client] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock [mysql_upgrade] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock Above we can see the password. But we are just going to use(GUx0RblkD3sPhHL5) that in the prompt. `mysql -u debian-sys-maint -p Enter password: ` Now provide the password (GUx0RblkD3sPhHL5). Now exit from MySQL and log in again as: `mysql -u root -p Enter password: `

现在提供新密码。这是所有。我们有新密码供以后使用。

这对我很管用。

其他回答

如果其他答案都不适合您,并且您收到了以下错误:

mysqld_safe Logging to '/var/log/mysql/error.log'.
mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.
[1]+  Exit 1                  sudo mysqld_safe --skip-grant-tables

按照以下命令依次执行,直到重置密码:

# Stop your server first
sudo service mysql stop

# Make the MySQL service directory.
sudo mkdir /var/run/mysqld

# Give MySQL permission to work with the created directory
sudo chown mysql: /var/run/mysqld

# Start MySQL, without permission and network checking
sudo mysqld_safe --skip-grant-tables --skip-networking &

# Log in to your server without any password.
mysql -u root mysql


# Update the password for the root user:
UPDATE mysql.user SET authentication_string=PASSWORD('YourNewPasswordBuddy'), plugin='mysql_native_password' WHERE User='root' AND Host='localhost';

# If you omit (AND Host='localhost') section, it updates
# the root password regardless of its host

FLUSH PRIVILEGES;
EXIT;

# Kill the mysqld_safe process
sudo service mysql restart

# Now you can use your new password to log in to your server
mysql -u root -p

# Take note for remote access. You should create a remote
# user and then grant all privileges to that remote user

我使用Ubuntu 16.04 (Xenial Xerus)和安装MySQL 5.7。

我也有同样的问题

禁止root用户登录。

我尝试了以下步骤:

get-select | grep mysql(获取mysql版本)。 dpkg-reconfigure mysql -服务器- 5.7 Mysql -u root -p

如果没有-p,则不会提示您询问密码。进入后,您可以按照以下步骤创建一个带有密码的用户:

CREATE USER 'your_new_username'@'your-hostname' IDENTIFIED BY 'your-password';

GRANT ALL PRIVILEGES ON *.* to 'your_new_username'@'your-hostname' WITH GRANT OPTION;

从根目录退出,从上面给出的<name>登录。

mysql -u <your_new_username> -p

由于某种原因,仍然不能输入MySQL。在所有。我建议养成使用mysql -u <name> -p的习惯。

如果问题仍然存在,请尝试强制修改密码:

/etc/init.d/mysql stop

mysqld_safe --skip-grant-tables &

mysql -u root

设置新的MySQL root用户密码:

use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit;

停止MySQL服务器:

/etc/init.d/mysql stop

启动MySQL服务器并测试它:

mysql -u root -p

请阅读官方文档:MySQL:如何重置Root密码

如果您可以访问终端:

MySQL 5.7.6及以上版本:

mysql

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

MySQL 5.7.5及以前版本:

mysql

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');

如果问题仍然存在,请尝试强制修改密码。

停止MySQL服务器(Linux):

/etc/init.d/mysql stop

停止MySQL服务器(Mac OS X):

mysql.server stop

使用——skip-grant-tables启动mysqld_safe守护进程:

mysqld_safe --skip-grant-tables &
mysql -u root

设置新的MySQL root用户密码:

use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit;

停止MySQL服务器(Linux):

/etc/init.d/mysql stop

停止MySQL服务器(Mac OS X):

mysql.server stop

启动MySQL服务器服务,测试以root用户登录:

mysql -u root -p
