在什么情况下,需要重置root密码呢?那就是我们忘记了。还有一种比较坑的,那就是笔者的这种情况。按照正常的情况下,MySQL安装完之后,会弹出一个对话框,显示着一个临时的root密码,但无论笔者如何重装MySQL,始终不给我一个临时的root的密码,导致笔者一直无法登陆MySQL,没办法,只能用硬的,那就是重置密码。

 

停止MySQL的服务,打开系统的偏好设置,找到MySQL 进去后,点击Stop MySQL Server即可。

step1:
苹果->系统偏好设置->最下边点mysql 在弹出页面中 关闭mysql服务(点击stop mysql server)
step2:
进入终端输入:cd /usr/local/mysql/bin/
回车后 登录管理员权限 sudo su
回车后输入以下命令来禁止mysql验证功能 ./mysqld_safe --skip-grant-tables &
回车后mysql会自动重启(偏好设置中mysql的状态会变成running)

 

 

开启两个终端,在第一个终端输入sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables,输入当前用户的密码:

ERROR 1045 (28000): Access denied for user root@localhost (using password: NO)

那么就换下面这种:

macdeMacBook-Pro:~ mac$ mysql -uroot -h127.0.0.1 -p
Enter password: 
ERROR 1045 (28000): Access denied for user root@localhost (using password: YES)

 

然后在第二个终端输入sudo /usr/local/mysql/bin/mysql -u root,然后输入当前用户的密码后,出现以下的界面

然后输入命令UPDATE mysql.user SET authentication_string=PASSWORD(‘新密码‘) WHERE User=‘root‘;回车,出现以下的界面,说明修改成功。
mysql> UPDATE mysql.user SET authentication_string=PASSWORD(123456) WHERE User=root;
Query OK, 1 row affected, 1 warning (0.00 sec)
Rows matched: 1  Changed: 1  Warnings: 1

接下来输入FLUSH PRIVILEGES;回车,出现下面的界面
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.01 sec)

最后,输入\q,退出。关闭第一个终端,回到系统的偏好设置,重新开启MySQL即可。
