I’m currently maintaining a dedicated web server(Ubuntu 14) running NGINX, MYSQL and a wildcard SSL for the main domain., running OpenSSL 1.0.1f 6 Jan 2014.
What would be the best way to install TLS 1.1, TLS 1.2 ?
The Encryption that the server already supports, thought SSLv1, SSLV2, SSL3 are deprecated.

TLS1.2 is now available for apache, to add TLSs1.2 you just need to add in your https virtual host configuration:
SSLProtocol -all +TLSv1.2
-all is removing other ssl protocol (SSL 1,2,3 TLS1)
+TLSv1.2 is adding TLS 1.2
for more browser compatibility you can use
SSLProtocol -all +TLSv1 +TLSv1.1 +TLSv1.2
by the way you can increase the Cipher suite, too using:
SSLCipherSuite EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:ECDHE-RSA-AES128-SHA:DHE-RSA-AES128-GCM-SHA256:AES256+EDH:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GC$
