在OS X操作系统下设置MySQL root用户密码

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.
Your MySQL connection id is 224
Server version: 5.5.13 MySQL Community Server (GPL)

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

我不需要密码就能进入mysql命令行!

为什么会这样?

其他回答

现有答案中提到的方法不适用于MySQL 5.7.6或更高版本。根据MySQL文档，这是推荐的方法。

B.5.3.2.3重置Root用户密码:通用说明

MySQL 5.7.6及以上版本:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

参考:https://dev.mysql.com/doc/refman/5.7/en/resetting-permissions.html

停止mysqld服务器。

Mac OS X:系统首选项→MySQL→停止MySQL服务器 Linux(从终端):sudo systemctl停止mysqld.service

Start the server in safe mode with privilege bypass From Terminal: sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables In a new terminal window: sudo /usr/local/mysql/bin/mysql -u root This will open the MySQL command-line client. From here enter: UPDATE mysql.user SET authentication_string=PASSWORD('NewPassword') WHERE User='root'; FLUSH PRIVILEGES; quit Stop the mysqld server again and restart it in normal mode. Mac OS X (From Terminal): sudo /usr/local/mysql/support-files/mysql.server restart Linux Terminal: sudo systemctl restart mysqld

这个解决方法在我的笔记本电脑上工作!

Mac与macOS v10.14.5 (Mojave)。

MySQL 8.0.17是用Homebrew安装的。

执行如下命令找到MySQL的路径编译mysql信息一旦路径已知，我运行这个: /usr/local/Cellar/mysql/8.0.17/bin/mysqld_safe——skip-grant-table 在另一个终端，我运行: Mysql -u root 在该终端中，我使用以下方法更改了root密码: 更新mysql。user='root'; 说完我就跑: 冲洗特权;

voilà，密码被重置。

如果你忘记了你的密码或者想把它改成你的MySQL:

Start your terminal and enter: sudo su Enter the password for you system Stop your MySQL server: sudo /usr/local/mysql/support-files/mysql.server stop Leave this window open, run second terminal window and enter here: mysql -u root And change your password for MySQL: UPDATE mysql.user SET authentication_string=PASSWORD('new_password') WHERE User='root'; where "new_password" - your new password. You don't need old password for MySQL. Flush, quit and check your new password: FLUSH PRIVILEGES; Close all windows and check your new password for MySQL.

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';`
