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

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

我不需要密码就能进入mysql命令行!

为什么会这样?

当我安装OS X v10.10 (Yosemite)时，MySQL出现了一个问题。我试了很多方法，但都没用。其实我找到了一个很简单的方法。试试这个。

首先以超级用户(su)权限登录到终端。 sudo苏停止MySQL sudo /usr/local/mysql/support-files / mysql。服务器停止安全模式启动: Sudo mysqld_safe——skip-grant-tables 打开另一台终端，以su权限登录，然后无需密码登录MySQL客户端(MySQL) Mysql -u root 修改密码更新mysql。SET Password ('new_password') WHERE user ='root'; 冲洗的特权冲洗特权; 现在你完成了。

在新的MySQL 5.7版本中，由于某些原因MySQL的二进制命令没有附加到shell中，你必须这样做:

安装完成后重新启动Mac。 MySQL开始: System Preferences→MySQL→Start按钮进入终端的MySQL install文件夹: cd /usr/local/mysql/bin/ 访问MySQL: ./mysql -u root -p 并输入为安装提供的初始密码。在MySQL客户端修改密码: mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPassword'

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.

$ 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.

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

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';
