在Arch Linux上

软件包:mysql 8.0.29-1

对我有用的是:

Edit my.cnf file, normally can be found at /etc/mysql/my.cnf and append this skip-grant-tables at the bottom/end of the file. Restart mysql service by invoking sudo systemctl restart mysqld Ensuring mysql service has started properly by invoking sudo systemctl status mysqld Login to mysql using 'root' by invoking mysql -u root -p Flush privileges by invoking flush privileges; Create new user by CREATE USER 'root'@'localhost' IDENTIFIED BY 'rootpassword'; (If you plan to use this db with PHP), you should instead use this CREATE USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'rootpassword'; Check whether your changes have reflected in db by invoking the following in sequence: use mysql; SELECT User, password_last_changed FROM user; Exit mysql console and comment/remove skip-grant-tables by editing my.cnf file (Refer to step 1 for the location) Restart the mysql service (Refer to step 2 and step 3)

就这些。

窗口:

cd \ampps\mysql\bin ：

mysql.exe -u root -pmysql

mysql启动后(可以看到shell是这样的mysql>) 使用这个查询:

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

请再次使用root访问

根据我的经验，如果你没有sudo，它是行不通的。所以确保你的命令是;

sudo mysql -uroot -p

在我的Debian 10的情况下，错误

ERROR 1698 (28000): Access denied for user 'root'@'localhost'

(好方法)解决了

sudo mysql -u root -p mysql

不好的方法:

mysql -u root -p mysql

修复macOS

Install MySQL from https://downloads.mysql.com/archives/community/ (8.x is the latest as on date, but ensure that the version is compatible with the macOS version) Give password for root (let <root-password> be the password) during installation (don't forget to remember the password!) Select Use Legacy Password Encryption option (that is what I had used and did not try for Use Strong Password Encryption option) Search and open MySQL.prefPane (use search tool) Select Configuration tab Click Select option of Configuration File Select /private/etc/my.cnf From terminal open a new or existing file with name /etc/my.cnf (vi /etc/my.cnf) add the following content: [mysqld] skip-grant-tables Restart mysqld as follows: ps aux | grep mysql kill -9 <pid1> <pid2> ... (grab pids of all MySQL related processes) mysqld gets restarted automatically Verify that the option is set by running the following from terminal: ps aux | grep mysql > mysql/bin/mysqld ... --defaults-file=/private/etc/my.cnf ... (output) Run the following command to connect (let mysql-<version>-macos<version>-x86_64 be the folder where MySQL is installed. To grab the actual folder, run ls /usr/local/ and copy the folder name): /usr/local/mysql-<version>-macos<version>-x86_64/bin/mysql -uroot -p<root-password>

'-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。
