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
在Mac上，如果你在使用安装时提供的第一个密码登录时遇到问题，也许你可以简单地关闭MySQL进程，然后再尝试。
So:
执行如下命令查看MySQL的PID: mysql | grep -v grep 终止进程: Kill -15[进程id]
可以使用初始密码登录:
mysql -uroot -p
它要求你输入密码。只需输入初始密码。
其他回答
一句话就解决了我的问题。
sudo dpkg-reconfigure mysql-server-5.5
我也遇到了同样的问题。我做了:
打开cmd 进入C:\Program Files\MySQL\MySQL Server 8.0\bin> (MySQL Server 8.0可能不同，取决于你安装的服务器) 然后输入以下命令mysql -u root -p 它会提示输入密码…简单地按Enter，因为有时你在安装时输入的密码会变为空白。
现在您可以简单地访问数据库。
这个解决方案在Windows平台上很适合我。
当您的密码丢失时就会发生这种情况。
忘记密码时的修改步骤:
Stop MySQL Server (on Linux): sudo systemctl stop mysql Start the database without loading the grant tables or enabling networking: sudo mysqld_safe --skip-grant-tables --skip-networking & The ampersand at the end of this command will make this process run in the background, so you can continue to use your terminal and run mysql -u root (as root). It will not ask for a password. If you get error like as below: 2018-02-12T08:57:39.826071Z mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists. mysql -u root ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) [1]+ Exit 1 Make MySQL service directory. sudo mkdir /var/run/mysqld Give MySQL user permission to write to the service directory. sudo chown mysql: /var/run/mysqld Run the same command in step 2 to run MySQL in background. Run mysql -u root. You will get the MySQL console without entering a password. Run these commands FLUSH PRIVILEGES; For MySQL 5.7.6 and newer ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password'; For MySQL 5.7.5 and older SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new_password'); If the ALTER USER command doesn't work use: UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHERE User = 'root' AND Host = 'localhost'; Now exit To stop the instance started manually: sudo kill `cat /var/run/mysqld/mysqld.pid` Restart MySQL sudo systemctl start mysql
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。
我也遇到过类似的问题:
错误1045(28000):用户“root”@“localhost”(正在使用)被拒绝访问 密码:没有)
但对我来说，这个原因真的很愚蠢。 我从Word文档复制了该命令，问题是连字符没有ASCII 0x2D代码，而是Unicode 0xE2 0x80 0x93 UTF-8序列(代码点U+2013 EN DASH)。
错误的方式:
mysql -u root –pxxxx
正确的方式:
mysql -u root -pxxxx
两者看起来一样，但并不相同(尝试一下，复制和粘贴替换密码)。
面对这种类型的错误，建议尝试输入命令，而不是复制和粘贴。
