Linux用户密码期限修改

今天有开发报故，sftp无法登录。检查服务都是正常的，之前3月份也出现过此问题，当时忙没有注意，现在看每3个月出现问题。这才想到是密码过期导致的。

先重置用户密码，发现过期日志为Oct 08, 2017，有效期为90天。

[[email protected]01 ~]# chage -l testuser
Last password change     : Jul 10, 2017
Password expires     : Oct 08, 2017
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

修改密码为永不过期，修改后见红色标注

[[email protected] ~]# chage -M 99999 testuser
[[email protected] ~]# chage -l testuser
Last password change                    : Jul 10, 2017

Account expires                        : Oct 16, 2243
Minimum number of days between password change        : 0
Maximum number of days between password change        : 99999
