The following will be my recent reading study to make a note, of course, this is for reference only, there may be some of their own speculation and ideas, not authoritative basis, the improper place also want to point out.

First, install Thrift
Download thrift, here, I'm using this version of thrift-0.7.0-dev.tar.gz.
Tar xzf thrift-0.7.0-dev.tar.gz
cd thrift-0.7.0-dev
sudo./configure--with-cpp=no--with-ruby=no
