How to install bpf tools for linux

This article is to share with you the linux installation of bpf tools tutorials, I believe that most people do not know how to install, in order to let you learn, to give you a summary of the following content, without saying much, let's read on.

Note: BPF relies on a higher version of the linux kernel.

Recommended OS kernel version > = 4.1 (kernel version 4.9 or later is recommended)

You also need to enable some kernel configuration options. These options are now enabled by default in many distributions, so you don't usually need to change them. They are:

CONFIG_BPF=y, CONFIG_BPF_SYSCALL=y, CONFIG_BPF_JIT=y, CONFIG_HAVE_EBPF_JIT=y, CONFIG_BPF_EVENTS=y.

Take CentOS7.6 as an example to demonstrate the steps for installing executable files (for the installation of ubuntu, please refer to the url below. The steps are basically the same)
