MACMYSQL

 问题1：初次安装后无法进入问题

b.  打开终端，输入：

 

    　　 sudo /usr/local/mysql/bin/mysqld_safe --skip-grant-tables

 

c.  打开另一个新终端，输入:

 

    　　 sudo /usr/local/mysql/bin/mysql -u root

 

    　　 UPDATE mysql.user SET authentication_string=PASSWORD('新密码') WHERE User='root';

       注意authentication_string有下划线

    　　 FLUSH PRIVILEGES;

 

     　　\q

d. 重启MySQL.

 

问题2：ERROR 1820 (HY000): You must reset yourpassword using ALTER USER statement before executing this statement.
