Nginx : SSL/TLS Setting2020/08/28

	Enable SSL/TLS setting to use secure encrypted connection.
[1]	Get SSL certificates, refer to here.
[2]	Configure Nginx. For example, enable SSL/TLS on default site.

root@www:~#

vi /etc/nginx/sites-available/default

# add to the end

# replace servername and path of certificates to your own one

server {
       listen       443 ssl http2 default_server;
       listen       [::]:443 ssl http2 default_server;
       server_name  www.srv.world;
       root         /var/www/html;

       ssl_certificate "/etc/letsencrypt/live/www.srv.world/fullchain.pem";
       ssl_certificate_key "/etc/letsencrypt/live/www.srv.world/privkey.pem";
       ssl_session_cache shared:SSL:1m;
       ssl_session_timeout  10m;

       index index.html
       include /etc/nginx/default.d/*.conf;

       location / {
              try_files $uri $uri/ =404;
       }

       error_page 404 /404.html;
              location = /40x.html {
       }

       error_page 500 502 503 504 /50x.html;
              location = /50x.html {
       }
}

root@www:~#

systemctl restart nginx

[3]	If you'd like to set HTTP connection to redirect to HTTPS (Always on SSL/TLS), configure like follows.

root@www:~#

vi /etc/nginx/sites-available/default

# add into the section of listening 80 port

server {
        listen 80 default_server;
        listen [::]:80 default_server;
        return 301 https://$host$request_uri;

root@www:~#

systemctl restart nginx

[4]	Verify to access to the test page from a client computer with a Web browser via HTTPS. If you set Always On SSL/TLS, access with HTTP to verify the connection is redirected to HTTPS normally, too.
