== Install OpenSSL 1.0.1 through yum ==
SPDY requires OpenSSL 1.0.1 or higher. You can do yum installation <code>yum install openssl-devel</code> if system default package version meets the requirement (Currently CentOS 6 and 7 come with OpenSSL 1.0.1 or above). You can check OpenSSL version by running the command <code>yum search openssl-devel</code> before the package
installation or running the command <code>openssl version</code> if the package has been installed. <code>/usr</code> is the default path to OpenSSL and <code>/usr/openssl</code> is the name of OpenSSL directory.
