# linux 使用chage 设置密码永不过期
Date: 2019-04-28


    vmware安装的虚拟机， 今天登录忽然提示“You must change your password now and login again!”， 密码过期了， 我登录设置了ssh免密登录， 输入原始密码，输入新密码后解决。修改成功登录后看了下，密码有效期60天。 通过chage 修改应用用户密码永不过期。

```
weida@vm-134:~$ chage -l weida

Password inactive : Jul 07, 2019

Minimum number of days between password change : 0
Maximum number of days between password change : 60
