方法1: 用SET PASSWORD命令
1
mysql -u root
2
3
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('newpass');
方法2:用mysqladmin
1
mysqladmin -u root password "newpass"
如果root已經(jīng)設(shè)置過密碼,采用如下方法
1
mysqladmin -u root password oldpass "newpass"
方法3: 用UPDATE直接編輯user表
1
mysql -u root
2
3
mysql> use mysql;
4
5
mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';
6
7
mysql> FLUSH PRIVILEGES;
在丟失root密碼的時候,可以這樣
1
mysqld_safe --skip-grant-tables&
2
3
mysql -u root mysql
4
5
mysql> UPDATE user SET password=PASSWORD("new password") WHERE user='root';
6
7
mysql> FLUSH PRIVILEGES;
