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已经设置过密码,采用如下方法
MysqLadmin -u root password oldpass "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
MysqLd_safe --skip-grant-tables&
MysqL -u root
MysqLMysqL> UPDATE user SET password=PASSWORD("new password") WHERE user='root';
MysqL> FLUSH PRIVILEGES;
