Überblick

  • Ich verwendet nginx als HTTP/2 Server auf einem Raspberry Pi
  • PHP soll in allen Stufen möglich sein

Authentifizierung

  • System-Voraussetzung
apt-get install apache2-utils
  • in der Host.conf
   auth_basic           "Administrator’s Area";
   auth_basic_user_file /etc/apache2/.htpasswd;
  • in der Kommandozeile
htpasswd -bc /srv/ngx/orgamon-2.dyndns.org/.htpasswd username ***pwd***

Stufe 1, :80 HTTP-Server

apt-get install nginx
apt-get install php-fpm
  • orgamon-2.dyndns.org
server {
       listen 80 default_server;
       listen [::]:80 default_server;

       root /srv/ngx/orgamon-2.dyndns.org;

       index index.html index.htm index.nginx-debian.html;

       server_name orgamon-2.dyndns.org;

       location / {
               # First attempt to serve request as file, then
               # as directory, then fall back to displaying a 404.
               try_files $uri $uri/ =404;
       }

       location ~ \.php$ {
               include snippets/fastcgi-php.conf;
               fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
       }

}

Stufe 2, :443 HTTPS-Server (TLS 1.2)

  • Port 80 + 443 auf den Server lenken
apt-get install certbot
certbot certonly --rsa-key-size 4096
  • /etc/nginx/sites-enabled/orgamon-2.dyndns.org
server {

       listen 443 ssl default_server;
       ssl_protocols TLSv1.2;

       root /srv/ngx/orgamon-2.dyndns.org;

       index index.html index.htm index.nginx-debian.html;

       server_name orgamon-2.dyndns.org;

       ssl_certificate /etc/letsencrypt/live/orgamon-2.dyndns.org/fullchain.pem;
       ssl_certificate_key /etc/letsencrypt/live/orgamon-2.dyndns.org/privkey.pem;

       location / {
               # First attempt to serve request as file, then
               # as directory, then fall back to displaying a 404.
               try_files $uri $uri/ =404;
       }

       location ~ \.php$ {
               include snippets/fastcgi-php.conf;
               fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
       }

Stufe 3, :443 HTTP/2 Server mit TLS 1.2

server {

      listen 443 ssl http2;
...

Stufe 4, :443 HTTP/2 Server mit TLS 1.3 (only!)


wget https://github.com/MatthewVance/nginx-build/raw/master/build-nginx.sh

# ich versuche den Debug-Mode mit hineinzukompilieren: http://nginx.org/en/docs/debugging_log.html
# und habe beim Build-Skript --with-debug hinzugemacht



chmod 777 build-nginx.sh
./build-nginx.sh
  • Probier aus, ob wirklich openssl-1-1-1 verwendet wird
nginx -V

dhparam

openssl dhparam -out /etc/nginx/dhparam-4096.pem 4096


  • Das dauert von 14:58 bis

nginx.conf

  • LÖSUNG: einfach einen aktuellen Browser verwenden, TLS 1.3 "final" war einfach für die Browser zu aktuell, die hätten einen "Draft xx" erwartet.
   server {

      # Content
      #
      server_name orgamon.com;
      root /srv/ngx/orgamon.com;
      index index.php;
      #
      location / {
              index index.php index.html;
              try_files $uri $uri/ =404;
      }
      #
      location ~ \.php$ {
              include fastcgi-php.conf;
              fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
      }

      # Transport
      #
      listen 443 ssl http2;
      ssl_protocols TLSv1.3;
      ssl_prefer_server_ciphers on;
      ssl_ecdh_curve auto;
      ssl_dhparam /etc/nginx/dhparam-4096.pem;
      ssl_certificate /etc/letsencrypt/live/orgamon.com/fullchain.pem;
      ssl_certificate_key /etc/letsencrypt/live/orgamon.com/privkey.pem;

      # Session
      #
      ssl_session_cache shared:SSL:20m;
      ssl_session_timeout 15m;
      ssl_session_tickets off;

      # Logging
      #
      error_log /srv/ngx/orgamon.com/error.log debug;
   }
