我刚刚在Mac OS x上安装了MySQL,下一步是设置root用户密码,所以我接下来这样做:
启动终端应用程序以访问Unix命令行。
在Unix提示符下,我执行了以下命令:
cd /usr/local/mysql/bin
./mysqladmin -u root password' password'
但是,当我执行命令时
./mysql -u root,这是答案:
Welcome to the MySQL monitor. Commands end with ; or \g.

我不需要密码就能进入mysql命令行!
为什么会这样?
MySQL 8有了很大的变化。我发现MySQL 8.0“如何重置根密码”文档的以下修改适用于Mac OS X。
创建一个临时文件$HOME/mysql.root.txt,用SQL更新根密码:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '<new-password>';
这使用mysql_native_password来避免身份验证插件'caching_sha2_password'无法加载错误,如果我省略该选项,我就会得到这个错误。
停止服务器,使用——init-file选项来设置根密码,然后重新启动服务器:
mysql.server stop
mysql.server start --init-file=$HOME/mysql.root.txt
mysql.server stop
mysql.server start
如果你忘记了MySQL的根密码,不记得或者想要闯入.....你可以在Linux或OS X的命令行中重置MySQL数据库密码,只要你知道你所在的机器的root用户密码:
(1)停止MySQL
sudo /usr/local/mysql/support-files/mysql.server stop
(2)安全模式启动:
sudo mysqld_safe --skip-grant-tables
(3)这将是一个持续的命令,直到进程结束,所以打开另一个shell/终端窗口,登录没有密码:
mysql -u root
UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';
在上面的UPDATE命令中,只需将'password'替换为您自己的新密码,请确保保留引号
(4)节省和安静
FLUSH PRIVILEGES;
\q
启动MySQL
sudo /usr/local/mysql/support-files/mysql.server start
$ export PATH=$PATH:/usr/local/mysql/bin
now,to make this permanent:
$ echo 'export PATH=$PATH:/usr/local/mysql/bin' >> ~/.bash_profile
next, start mysql in safe mode:
$ sudo mysqld_safe --skip-grant-tables;
If this does not work, go to System Preferences and stop MySQL server.
next, On the **other** terminal, you may use the below:
$ mysql -u root
mysql> USE mysql;
mysql> UPDATE mysql.user SET authentication_string=null WHERE
User='root';
mysql> FLUSH PRIVILEGES;
mysql> exit;
$ mysql -u root
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH
caching_sha2_password BY 'yourpassword';
$ mysql -u root -p
Enter password:
mysql> SELECT user();
next, start the mysql server in normal mode. and you're done with resetting your root password. this worked for mysql 8.0.17 ver. for me.

当您登录MySQL终端时,请尝试执行FLUSH PRIVILEGES命令。如果这不起作用,请在MySQL终端中尝试以下命令集
mysql -u root
mysql> USE mysql;
mysql> UPDATE user SET password=PASSWORD("NEWPASSWORD") WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit
用你想要的任何密码更改NEWPASSWORD。应该都准备好了!
更新:从MySQL 5.7开始,密码字段被重命名为authentication_string。修改密码时,使用以下查询来修改密码。所有其他命令保持不变:
mysql> UPDATE user SET authentication_string=PASSWORD("NEWPASSWORD") WHERE User='root';
请不要使用MySQL 8.0+
mysql> UPDATE mysql.user SET authentication_string='password' WHERE User='root';
因为它覆盖了authentication_string,它应该是一个哈希而不是纯文本,而是使用:
mysql> `ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';`
