问题描述:
今天同事反应,一个系统上的某些数据没有生成,看了下,怀疑定时任务没有执行,就看下了crontab,发现报了下面的错误:
[aimonitor@4A-LF-w08 ~]$ crontab -l Authentication token is no longer valid; new one required You (aimonitor) are not allowed to access to (crontab) because of pam configuration.
问题解决:
1.基于以上的现象在网上找了下解决方法,说的是可能用户密码过期了
2.查看用户的密码过期时间
[root@4A-LF-w08 ~]# chage -l aimonitor Last password change : Jan 16, 2018 Password expires : Apr 16, 2018 Password inactive : never Account expires : never Minimum number of days between password change : 6 Maximum number of days between password change : 90 Number of days of warning before password expires : 30
备注:通过以上的信息知道,密码在2018.4.16号过期,后续就没有数据产生了,时间是4.17号.
3.将账号设置为密码永不过期
[root@4A-LF-w08 ~]# chage -M 99999 aimonitor [root@4A-LF-w08 ~]# chage -l aimonitor Last password change : Jan 16, 2018 Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 6 Maximum number of days between password change : 99999 Number of days of warning before password expires : 30
4.再次检查crontab,发现crontab能够正常显示,同时定时任务也正常执行了.
