cron定时任务报错PAM unable to dlopen(pam_tally2.so): /lib/security/pam_tally2.so

在Ubuntu 22.04中，pam_tally2模块可能已经不再被支持或包含在系统默认的PAM模块中。因此，当系统尝试加载该模块时，无法找到对应的.so文件，需要使用pam_faillock.so来代替

先查找下是否存在pam_faillock.so模块

find /usr -name "pam_*.so"

没有 pam_tally2.so ,复制出来一个就解决了

cp /usr/lib/x86_64-linux-gnu/security/pam_faillock.so /lib/security/pam_tally2.so
