Problem: the lack of a shared library files
sudo: error while loading shared libraries: libaudit.so.1: can not open shared object file: No such file or directory
Solution:
1. Prepare audit-libs installation package
audit-libs-2.8.4-4.el7.x86_64.rpm
2. think of ways to upload to the / mnt directory within the server
# more /mnt/audit-libs-2.8 .4-4.el7.x86_64.rpm
installation audit-libs 3. reboot the server into single user mode or the recovery mode installation package
mnt / # rpm -ivh audit-libs -2.8.4-4.el7.x86_64.rpm
4. after installation reboot the server
# reroot
