修改密码多种方法
方法1: 用SET PASSWORD命令
mysql -u root
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');
方法2:用mysqladmin(在Linux命令行,不是在MySQL内部)
mysqladmin -u root password "newpass"
如果root已经设置过密码,采用如下方法
mysqladmin -u root password oldpass "newpass"
例如:
mysqladmin -uroot -pyeyilu password "newpass"
方法3: 用UPDATE直接编辑user表
mysql -u root
mysql> use mysql;
mysql> UPDATE user SET password = password('newpass') WHERE user = 'root';
mysql> FLUSH PRIVILEGES;
在丢失root密码的时候,可以这样
/usr/local/mysql/bin/mysqld_safe --skip-grant-tables &
mysql -u root -p
mysql> UPDATE mysql.user SET password=password("new password") WHERE user='root';
mysql> FLUSH PRIVILEGES;
