业务反馈腾讯线上EMR大数据集群机器下hadoop用户定时任务突然都失效了，crontab命令也不能执行，看了报错应该是密码过期被锁了。联系腾讯云技术支持还说他们都是设置的从不过期，甩了几张图打脸后就老实了，最后批量执行 chage -M 99999 hadoop 把集群机器 hadoop 用户密码都设置为永不过期问题解决。
[hadoop@10 ~]$ crontab -l You (hadoop) are not allowed to access to (crontab) because of pam configuration. [root@10 ~]# chage -l hadoop Last password change : Jul 31, 2023 Password expires : Oct 29, 2023 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 : 7 # 执行 chage -M 99999 hadoop 设置密码永不过期 [root@10 ~]# chage -l hadoop Last password change : Jul 31, 2023 Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7 # 如果执行完还是不行，比如出现下边这个情况： [root@10 ~]# chage -l hadoop Last password change : password must be changed Password expires : password must be changed Password inactive : password must be changed Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7 # 执行 passwd -d hadoop 然后就好了 [root@10 ~]# passwd -d hadoop Removing password for user hadoop. passwd: Success [root@10 ~]# chage -l hadoop Last password change : Oct 31, 2023 Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7
