I have installed opam, and after this I can access ocaml, ocamlc, buildocaml successfully.
But I am reading Real World OCaml which is asking me to run a tool called corebuild.
I am not able to install (or run) corebuild.
If I search for sudo find / -name corebuild... I can see files like

But still then I don't know how to run this tool.

You need to run opam install core to get corebuild.
More generally, you should look at the install instructions here, which will show you which libraries to install. Note that corebuild is a simple wrapper around ocamlbuild, and it assumes that you have core installed, and gives you the option of using it by default.
