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
一句话就解决了我的问题。
sudo dpkg-reconfigure mysql-server-5.5
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。
在终端输入:
mysql -u root -p
然后它会问你密码。

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。
在Ubuntu 16.04 (Xenial Xerus)和MySQL 5.7.13版本中，我能够通过以下步骤解决这个问题:
Follow the instructions from section B.5.3.2.2 Resetting the Root Password: Unix and Unix-Like Systems MySQL 5.7 reference manual When I tried #sudo mysqld_safe --init-file=/home/me/mysql-init & it failed. The error was in /var/log/mysql/error.log: 2016-08-10T11:41:20.421946Z 0 [Note] Execution of init_file '/home/me/mysql/mysql-init' started. 2016-08-10T11:41:20.422070Z 0 [ERROR] /usr/sbin/mysqld: File '/home/me/mysql/mysql-init' not found (Errcode: 13 - Permission denied) 2016-08-10T11:41:20.422096Z 0 [ERROR] Aborting
mysql-init的文件权限不是问题。我们需要编辑AppArmor权限。
Edit by sudo vi /etc/apparmor.d/usr.sbin.mysqld .... /var/log/mysql/ r, /var/log/mysql/** rw, # Allow user init file /home/pranab/mysql/* r, # Site-specific additions and overrides. See local/README for details. #include <local/usr.sbin.mysqld> } Do sudo /etc/init.d/apparmor reload Start mysqld_safe again. Try step 2 above. Check file /var/log/mysql/error.log. Make sure there is no error and the mysqld is successfully started. Run mysql -u root -p Enter password: Enter the password that you specified in mysql-init. You should be able to log in as root now. Shutdown mysqld_safe by sudo mysqladmin -u root -p shutdown Start mysqld the normal way by sudo systemctl start mysql
