考虑:

./mysqladmin -u root -p** '_redacted_'  

输出(包括输入密码):

输入密码: Mysqladmin: connect to server at 'localhost' failed错误 '用户'root'@'localhost'(使用密码:YES)拒绝访问'

我该如何解决这个问题?

需要检查的一件事是from-host筛选器。默认情况下可能是“localhost”。您正在尝试从远程客户端连接吗?将其更改为“%”。

打开并编辑/etc/my.cnf或/etc/mysql/my.cnf,具体取决于你的发行版。 在[mysqld]下添加skip-grant-tables 重新启动MySQL 你现在应该可以使用下面的命令MySQL -u root -p登录MySQL 运行mysql> flush特权; 设置新密码ALTER USER 'root'@'localhost' IDENTIFIED by 'NewPassword' 回到/etc/my.cnf,删除/comment skip-grant-tables 重新启动MySQL 现在你可以用新密码mysql -u root -p登录了

对于新Linux用户来说,这可能是一项艰巨的任务。让我用MySQL 8更新这个(目前可用的最新版本是8.0.12,截至2018-09-12)

Open "mysqld.cnf" configuration file at "/etc/mysql/mysql.conf.d/". Add skip-grant-tables to the next line of [mysql] text and save. Restart the MySQL service as "sudo service mysql restart". Now your MySQL is free of any authentication. Connect to the MySQL client (also known as mysql-shell) as mysql -u root -p. There is no password to be keyed in as of now. Run SQL command flush privileges; Reset the password now as ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPassword'; Now let's get back to the normal state; remove that line "skip-grant-tables" from "mysqld.cnf" and restart the service.

就是这样。

使用sudo修改密码:

sudo mysql

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'insert_password';

我在这里的位置:

UBUNTU 21.04 PHP 5.6.40-57 MYSQL 5.7.37

我们来配置一下

nano /etc/mysql/mysql.conf.d/mysqld.cnf

在底部,写下这个

skip-grant-tables

重新加载它

service mysql restart

'-p'参数不要求参数名和值之间有空格。

而不是

./mysqladmin -u root -p 'redacted'

Use

./mysqladmin -u root -p'redacted'

或者只是

./mysqladmin -u root -p

这将提示您输入密码。
