Saya saat ini menjalankan server Ubuntu 16.04.1 LTS menggunakan NGINX 1.11.9 dan openssl 1.0.2g.
Menurut semua yang saya baca, versi ini harus mendukung ALPN, namun ketika saya menjalankan tes pada alat HTTP / 2 Test KeyCDN, saya mendapatkan "ALPN tidak didukung"
Dan ketika saya mengeksekusi echo | openssl s_client -alpn h2 -connect example.com:443 | grep ALPN
, saya mendapatkan:
depth=3 C = SE, O = AddTrust AB, OU = AddTrust External TTP Network, CN = AddTrust External CA Root
verify return:1
depth=2 C = GB, ST = Greater Manchester, L = Salford, O = COMODO CA Limited, CN = COMODO RSA Certification Authority
verify return:1
depth=1 C = GB, ST = Greater Manchester, L = Salford, O = COMODO CA Limited, CN = COMODO RSA Domain Validation Secure Server CA
verify return:1
depth=0 OU = Domain Control Validated, OU = EssentialSSL Wildcard, CN = *.example.com
verify return:1
No ALPN negotiated
DONE
Tidak mengaktifkan ALPN menonaktifkan HTTP2 agar tidak sepenuhnya diaktifkan. Bagaimana cara saya mengaktifkan ALPN?
