需要查看pam認證模塊 vi /etc/pam.d/password-auth auth required pam_tally2.so file=/var/log/tallylog deny=3 even_deny_root unlock_time=1200

account required pam_tally2.so

用法： file=/var/log/tallylog – Default log file is used to keep login counts. deny=3 – Deny access after 3 attempts and lock down user. even_deny_root – Policy is also apply to root user. unlock_time=1200 – Account will be locked till 20 Min. (remove this parameters if you want to lock down permanently till manually unlock.)
