Mysql change password or forget password (transfer)

Method 1: Use the SET PASSWORD command

　　mysql -u root

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

Method 2: Using mysqladmin

　　mysqladmin -u root password "newpass"

　　If root has already set a password, use the following method

　　mysqladmin -u root password oldpass "newpass"

Method 3: Edit the user table directly with UPDATE

　　mysql -u root

　　mysql> use mysql;

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

　　mysql> FLUSH PRIVILEGES;

When you lose the root password, you can do this

　　mysqld_safe --skip-grant-tables&

　　mysql -u root mysql

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

　　mysql> FLUSH PRIVILEGES;
