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?

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。
在我的情况下，我发现我的根密码在日志文件“mysqld.log”，路径“/var/log”。
在我运行命令“mysql -u root -p”后，我输入我的root密码，我在/var/log/mysql .log中找到。
注意:对于MySQL 5.7+，请参见Lahiru对这个问题的回答。这包含了更多的最新信息。
对于MySQL < 5.7:
默认root密码为空(即空字符串)，而不是root。所以你可以登录为:
mysql -u root
安装完成后，您显然应该更改root密码:
mysqladmin -u root password [newpassword]
在大多数情况下，您还应该在广泛使用数据库之前设置个人用户帐户。

mysql -u root -p

如果你还没有设置密码，那么运行mysql -uroot。这对我很管用。
