NGINX HTTPs with self generated certificates

Follow the steps

1. Self Signed Certificate creation

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/nginx-selfsigned.key -out /etc/ssl/certs/nginx-selfsigned.crt

2. Create file at /etc/nginx/snippets/self-signed.conf

sudo nano /etc/nginx/snippets/self-signed.conf

With Contents

ssl_certificate /etc/ssl/certs/nginx-selfsigned.crt;
ssl_certificate_key /etc/ssl/private/nginx-selfsigned.key;

3. Create SSL Parms File

sudo nano /etc/nginx/snippets/ssl-params.conf

With contents

ssl_protocols TLSv1.2;
ssl_prefer_server_ciphers on;
ssl_dhparam /etc/ssl/certs/dhparam.pem;
ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384;
ssl_ecdh_curve secp384r1; # Requires nginx >= 1.1.0
ssl_session_timeout 10m;
ssl_session_cache shared:SSL:10m;
ssl_session_tickets off; # Requires nginx >= 1.5.9
# ssl_stapling on; # Requires nginx >= 1.3.7
# ssl_stapling_verify on; # Requires nginx => 1.3.7
resolver 8.8.8.8 8.8.4.4 valid=300s;
resolver_timeout 5s;
add_header X-Frame-Options DENY;
add_header X-Content-Type-Options nosniff;
add_header X-XSS-Protection "1; mode=block";

4. Now edit file /etc/nginx/nginx.conf and paste this

worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
 worker_connections 768;
 # multi_accept on;
}

http {

 ##
 # Basic Settings
 ##

 sendfile on;
 tcp_nopush on;
 types_hash_max_size 2048;
 # server_tokens off;

 # server_names_hash_bucket_size 64;
 # server_name_in_redirect off;

 include /etc/nginx/mime.types;
 default_type application/octet-stream;

 ##
 # SSL Settings
 ##

 ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE
 ssl_prefer_server_ciphers on;

 ##
 # Logging Settings
 ##

 access_log /var/log/nginx/access.log;
 error_log /var/log/nginx/error.log;

 ##
 # Gzip Settings
 ##

 gzip on;

 # gzip_vary on;
 # gzip_proxied any;
 # gzip_comp_level 6;
 # gzip_buffers 16 8k;
 # gzip_http_version 1.1;
 # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

 ##
 # Virtual Host Configs
 ##

 include /etc/nginx/conf.d/*.conf;
 include /etc/nginx/sites-enabled/*;
 server {
  listen 443 ssl;
  listen [::]:443 ssl;
  include snippets/self-signed.conf;
  include snippets/ssl-params.conf;

  location / {
                #proxy_pass http://127.0.0.1:3000;
                root /home/user/site/www;
                index  index.html index.htm;
                try_files $uri /index.html;
                proxy_set_header X-Forwarded-Proto $scheme;
        }

 }
}

5. Remove the default site entry

sudo rm /etc/nginx/sites-available

6. Restart NGINX

sudo service nginx restart
