Ṣiṣeto HTTPS pẹlu Jẹ ki Encrypt SSL Certificate For Nginx on RHEL/CentOS 7/6

Ṣafikun atokọ atẹle atẹle si Nginx.conf:

ssl_dhparam /etc/nginx/ssl/dhparams.pem;
ssl_session_timeout 30m;
ssl_session_cache shared:SSL:10m;
ssl_buffer_size 8k;
add_header Strict-Transport-Security max-age=31536000;

15. Tun bẹrẹ iṣẹ Nginx lati lo awọn ayipada ati tun ṣayẹwo ijẹrisi SSL rẹ nipasẹ didari kaṣe abajade ti tẹlẹ lati ọna asopọ ti a darukọ loke.

Igbesẹ 5: Tunse Nginx Free Jẹ ki Aifọwọyi Awọn iwe-ẹri SSL Encrypt

16. Jẹ ki Encrypt CA tu awọn iwe-ẹri SSL/TLS ọfẹ ọfẹ ti o wulo fun awọn ọjọ 90. Awọn iwe-ẹri le ṣe tunse pẹlu ọwọ ati lo ṣaaju ipari ni lilo ohun itanna webroot, laisi diduro olupin ayelujara rẹ, nipa ipinfunni awọn ofin isalẹ:
