Build Curl http2

Firstly, install the dev tools you’re doing to need.

yum -y groupinstall "Development Tools" yum -y install libev libev-devel zlib zlib-devel openssl openssl-devel git Next, we’re going to store a few things in /var/tmp and install the new version of openssl into /opt/openssl

mkdir /var/tmp cd /var/tmp wget https://www.openssl.org/source/openssl-1.0.2-latest.tar.gz tar -zxf openssl-1.0.2-latest.tar.gz
