In CentOS linux 7 (and 8), the file is actually blank .. well is has one comment line: # Placeholder file, no vDSO hwcap entries used in this kernel. If you want the error to go away, just as the root user, do: touch /etc/ld.so.conf.d/kernel-3.10.0-1127.19.1.el7.x86_64.conf chmod 444 /etc/ld.so.conf.d/kernel-3.10.0-1127.19.1.el7.x86_64.conf The above 2 commands should create a zero size file there and prevent the error. As to how you got the error .. it seems there is an issue with the kernel-3.10.0-1127.19.1.el7.x86_64 install on your machine, it is at least missing that file. If you are using that kernel .. you might want to re-install it instead to make sure all the files are there. There is a newer kernel released for EL7. As to the purpose of /etc/ld.so.conf.d/, info here: https://linux.101hacks.com/unix/ldconfig/
