If you are getting the error:
No binary module was found for your kernel. The kernel headers will be required
to build a module. And you can't get our other article working.. you need to edit:nano -w /etc/yum.repos.d/CentOS-Vault.repo
put at the end for example:
[C6.7-base]
name=CentOS-6.7 - Base
baseurl=http://vault.centos.org/6.7/os/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

[C6.7-updates]
name=CentOS-6.7 - Updates
