Mysql忘记密码怎么办？

1.打开配置文件修改

shell>vi /etc/my.cnf

skip-grant-tables

2.保存后重新启动MySQL

shell>service mysqld restart

3.这样就可以无密码进入了，然后修改密码

mysql>set password=password(‘123456aaa’);
ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

mysql>set global validate_password_policy=0;

mysql>set global validate_password_length=4;

mysql>set password=password(‘123456aaa’);
