where to get the official source install guide for haproxy 2.2.2 ?  
it’s better also to guide how to upgrade source install ( 1.\* or 2.0.\* or 2.1.8) .  
since the haproxy version is 1.5.\* in centos 7._, it will be grateful to guide how to upgrade from 1.5._ ( yum install ).

Don’t upgrade. Remove/Uninstall haproxy 1.5 _cleanly_ and then you can build from sources.

You can find more informations about this in the file `INSTALL` in the tarball.
