You (root) are not allowed to access to (crontab) because of pam configuration.

解決：

1.查看定時任務的日志/var/log/cron

pam_access(crond:account): access denied for user `root' from `cron'

2. 查看 /etc/pam.d/crond

root>more /etc/pam.d/crond

#
# The PAM configuration file for the cron daemon
#
#
# No PAM authentication called, auth modules not needed
account    required   pam_access.so
account    include    password-auth
session    required   pam_loginuid.so
session    include    password-auth
auth       include    password-auth

修改文件：

[root@~]# cp /etc/pam.d/crond /etc/pam.d/crond.bak
[root@ ~]# vim /etc/pam.d/crond

account    sufficient   pam_access.so
account    include    system-auth
session    sufficient   pam_loginuid.so
session    include    system-auth
auth sufficient pam_rootok.so auth required pam_env.so auth include system-auth

重啟crond 

[root@~]# /etc/init.d/crond restart
停止 crond： [確定]
正在啟動 crond： [確定]

 

重新登錄root

[root@~]# crontab -e

 

 完美解決
