MySQL修改root密碼的多種方法,mysql修改root

方法1: 用SET PASSWORD命令

  mysql -u root

  mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');

方法2:用mysqladmin

  mysqladmin -u root password "newpass"

  如果root已經設定過密碼,採用如下方法

  mysqladmin -u root password oldpass "newpass"

方法3: 用UPDATE直接編輯user表

  mysql -u root

  mysql> use mysql;

  mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';

  mysql> FLUSH PRIVILEGES;

在丟失root密碼的時候,可以這樣

  mysqld_safe --skip-grant-tables&

  mysql -u root mysql

  mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='root';

  mysql> FLUSH PRIVILEGES;
