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?

当前回答

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

在终端中，写入mysql -u root -p并点击Return。

输入您必须记下的当前MySQL密码。

并设置密码:

SET PASSWORD = PASSWORD('new_password');

更多细节请参考这里的文档。

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.

在终端试试这个:

/usr/local/bin/mysql_secure_installation

macOS v10.14 (Mojave)及更高版本，从Mac OS X DMG安装程序安装5.7.26。

当尝试使用其他用户发布的UPDATE命令时，会导致以下错误:

错误1820 (HY000):在执行此语句之前，您必须使用ALTER USER语句重置密码。

复制安装程序提供给您的密码，打开终端，然后执行以下操作:

mysql -uroot -p
ALTER USER 'root'@'localhost' IDENTIFIED BY 'YOURPASSWORDHERE';
