Getting the following error may be deceiving:
Error! echo Your kernel headers for kernel 3.10.0-1062.1.1.el7.x86_64 cannot be found at /lib/modules/3.10.0-1062.1.1.el7.x86_64/build or /lib/modules/3.10.0-1062.1.1.el7.x86_64/source.
Because you may have already installed the kernel-headers package for the current kernel and still to get the same error. So what is missing?
In fact, the kernel headers for compiling a kernel module is in kernel-devel package.

If you have used other Linux distribution the “kernel headers”/”linux headers” package just means what it is named. In the CentOS 7 world there are two packages:
