# Nginx configuration 1. Create `/etc/nginx/conf.d/foundkey.conf` or `/etc/nginx/sites-available/foundkey.conf` and copy the following example to the file.\ (The file name does not have to be "foundkey".) 2. Edit as follows: 1. Replace example.tld with the domain you have prepared.\ `ssl_certificate` and `ssl_certificate_key` should be the path to the certificate obtained from Let's Encrypt. 2. If using a CDN such as Cloudflare, remove 4 lines from "If it's behind another reverse proxy or CDN, remove the following." 3. If you create `/etc/nginx/sites-available/foundkey.conf`, create symlink as `/etc/nginx/sites-enabled/foundkey.conf`.\ `sudo ln -s /etc/nginx/sites-available/foundkey.conf /etc/nginx/sites-enabled/foundkey.conf` 4. Run `sudo nginx -t` to verify that the configuration file will be loaded successfully. 5. Run `sudo systemctl restart nginx` to restart nginx. # Nginx cofig example ```nginx # For WebSocket map $http_upgrade $connection_upgrade { default upgrade; '' close; } proxy_cache_path /tmp/nginx_cache levels=1:2 keys_zone=cache1:16m max_size=1g inactive=720m use_temp_path=off; server { listen 80; listen [::]:80; server_name example.tld; # For SSL domain validation root /var/www/html; location /.well-known/acme-challenge/ { allow all; } location /.well-known/pki-validation/ { allow all; } location / { return 301 https://$server_name$request_uri; } } server { listen 443 ssl http2; listen [::]:443 ssl http2; server_name example.tld; ssl_session_timeout 1d; ssl_session_cache shared:ssl_session_cache:10m; ssl_session_tickets off; # To use Let's Encrypt certificate ssl_certificate /etc/letsencrypt/live/example.tld/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.tld/privkey.pem; # To use Debian/Ubuntu's self-signed certificate (For testing or before issuing a certificate) #ssl_certificate /etc/ssl/certs/ssl-cert-snakeoil.pem; #ssl_certificate_key /etc/ssl/private/ssl-cert-snakeoil.key; # SSL protocol settings ssl_protocols TLSv1.2 TLSv1.3; ssl_ciphers ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384; ssl_prefer_server_ciphers off; ssl_stapling on; ssl_stapling_verify on; # Change to your upload limit client_max_body_size 80m; # Proxy to Node location / { proxy_pass http://127.0.0.1:3000; proxy_set_header Host $host; proxy_http_version 1.1; proxy_redirect off; # If it's behind another reverse proxy or CDN, remove the following. proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto https; # For WebSocket proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; # Cache settings proxy_cache cache1; proxy_cache_lock on; proxy_cache_use_stale updating; add_header X-Cache $upstream_cache_status; } } ```
