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。

对于Ubuntu/Debian用户

(它可能适用于其他发行版，尤其是基于debian的发行版。)

运行以下命令以root身份连接(不需要任何密码)

sudo /usr/bin/mysql --defaults-file=/etc/mysql/debian.cnf

如果你不想每次以根用户连接时都添加——defaults-file，你可以将/etc/mysql/debian.cnf复制到你的主目录:

sudo cp /etc/mysql/debian.cnf ~/.my.cnf

然后:

sudo mysql

解决方法:放弃!

听我说完。我花了整整两天的时间试图让MySQL工作，但没有任何效果，总是被权限错误卡住，没有一个是通过这个问题的答案解决的。我想，如果我继续下去，我会疯掉的。

由于没有耐心，我发送了安装SQLite的命令，只使用了450 KB，它从一开始就工作得很好。

如果你没有圣人的耐心，那就使用SQLite吧，这样可以为你节省大量的时间、精力、痛苦和存储空间。

有时会在安装时设置默认密码-如文档中所述。可以通过以下命令确认。

sudo grep 'temporary password' /var/log/mysqld.log

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>

我找到的所有解决方案都比必要的要复杂得多，没有一个适合我。这是解决我问题的办法。不需要重新启动mysqld或使用特殊权限启动它。

sudo mysql

-- for MySQL
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root';

-- for MariaDB
ALTER USER 'root'@'localhost' IDENTIFIED VIA mysql_native_password USING PASSWORD('root');

通过一个查询，我们将auth_plugin更改为mysql_native_password，并将根密码设置为root(可以在查询中随意更改)。

现在您应该可以使用root登录了。更多信息可以在MySQL文档或MariaDB文档中找到。

(使用Ctrl + D或输入Exit退出MySQL控制台。)
