The easiest way by far is to install TeX Live 2014 from one of the
And from what I understood the TL 2014 testing packages for Debian are
ready as well.
The second-easiest thing is to replace the existing luatex binary and
run "fmtutil --all" or "sudo fmtutil-sys --all" (or "--byfmt lualatex"
or something similar) to generate the formats for you.
Please keep in mind that once you run those commands, you might need
to deleted the user-generated formats when you upgrade TeX Live.

I'm not 100% sure if that applies in your case, but if you place the
luatex binary at some weird location, you might need to redefine a
bunch of configuration variables to allow luatex to properly find the
relevant files. The search is always done relative to the original
binary. Unless you know what you are doing ... it could get tricky and
it could depend on how exactly you installed TL. And if you took
Debian's TL, there is a fair chance that texmf.cnf uses different
variables than your self-compiled binary. You can take a look at all
instances of texmf.cnf on your machine.
