#重置密码
[root@iZ2zegctspnn963lglh798Z usr]# cd /usr/winnx/
[root@iZ2zegctspnn963lglh798Z winnx]# passwd winn
Changing password for user winn.
New password: 
Retype new password: 
passwd: all authentication tokens updated successfully.  

2. 赋予sudo权限

#修改文件
[root@iZ2zegctspnn963lglh798Z winnx]# vim /etc/sudoers 
#添加下面内容
winn    ALL=(ALL)       ALL
#强制保存
:wq!
