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
我可以通过执行这条语句来解决这个问题
sudo dpkg-reconfigure mysql-server-5.5
这将改变根密码。
其他回答
一句话就解决了我的问题。
sudo dpkg-reconfigure mysql-server-5.5
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。

回答Ubuntu 20.04 (Focal Fossa)(也可能是其他发行版)。
在四处游荡了几天之后…这些答案对我都没用，我就这么做了，而且成功了!
始终在Bash shell中:
sudo systemctl disable mysql
为了阻止守护进程在启动时启动。
sudo apt purge mysql-server
and
sudo apt purge mysql-community-server*
在那里，它警告你，你将删除配置文件…所以它起作用了!因为他们就是捣乱的人!
sudo autoremove
删除所有遗留的包。
然后重启(也许这是可选的，但我做到了)。 另外，我从MySQL官方网页下载了MySQL -server-8.0:
sudo apt install mysql-server
它正在工作的信号是，当您输入上面的命令时，系统要求您输入根密码。
最后:
mysql -u root -p
还有你之前输入的密码。
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
