打开终端
sudo /usr/local/mysql/support-files/mysql.server stop
sudo /usr/local/mysql/bin/mysqld_safe –skip-grant-tables
打开另一个终端
sudo /usr/local/mysql/bin/mysql -u root
UPDATE mysql.user SET authentication_string=PASSWORD(‘新密码’) WHERE User=’root’;
FLUSH PRIVILEGES;
\q
sudo /usr/local/mysql/support-files/mysql.server restart
*以上方法针对 mysql V5.7.9,
旧版的mysql请使用:UPDATE mysql.user SET Password=PASSWORD(‘新密码’) WHERE User=’root’;
