Linux.nginx

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 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)

apt-get install certbot
certbot certonly

• /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

13.09.2018

• kein Erfolg, der firefix Client sagt Protokoll-Error

06.10.2018

• Es gibt neue SSL Debug Strings
• Ich will es nochmal mit TLS 1.3 versuchen
• OpenSSL 1.1.1
• nginx 1.15.5

• geht wieder nicht (TLS 1.2 geht jedoch)!

• FireFox meldet

 SSL_ERROR_PROTOCOL_VERSION_ALERT

• Nginx-Debug
