I try to install the latest version of nginx (>= 1.9.5) on a fresh amazon linux to make use of http2. I followed the instructions that are described here -> http://nginx.org
Note, there is no 1.10 where you're looking. You can see the list here
http://nginx.org/packages/mainline/centos/7/x86_64/RPMS/
After you yum update
use yum search nginx
to see the different versions you have and choose a specific one:
yum search nginx
on centos 6 gives
nginx.x86_64 : A high performance web server and reverse proxy server
nginx16.x86_64 : A high performance web server and reverse proxy server
nginx18.x86_64 : A high performance web server and reverse proxy server
I have two versions to choose from, 1.6 and 1.8.
