Linux设置用户密码的有效期限
解决：
先查看密码过期时间，现在是90天
[root@01 ~]# chage -l testuser
Last password change : Jul 10,
Password expires : Oct 08,
Password inactive : never
Account expires : never
Minimum number of days between password change : 0
Maximum number of days between password change : 90
Number of days of warning before password expires : 10
用命令修改过期时间为永久，然后查看Password expires : never 和 Maximum number of days between password change : 99999修改成功
[root@01 ~]# chage -M 99999 testuser
[root@01 ~]# chage -l testuser
Last password change : Jul 10,
Password expires : never
Password inactive : never
Account expires : Oct 16, 2243
Minimum number of days between password change : 0
Maximum number of days between password change : 99999
