+These NGINX configurations set up HTTP servers at port 80. HTTPS on port 443 should be set up using [certbot](https://www.nginx.com/blog/using-free-ssltls-certificates-from-lets-encrypt-with-nginx/).
+
+## Static web page
+The URL [example.ert.space](http://example.ert.space) will point to files in `/srv/www/example.ert.space`.
+```nginx
+server {
+    listen 80;
+    listen [::]:80;
+    root /srv/www/example.ert.space;
+    server_name example.ert.space;
+    error_page 404 /404.html;
+    location / {
+        try_files $uri $uri/ =404;
+    }
+}
+```
+
+## PHP site with HTTP authentication
+The URL [example.ert.space](http://example.ert.space) will point to the PHP application at `/srv/www/example.ert.space/index.php`. HTTP authentication done as indicated [here](https://docs.nginx.com/nginx/admin-guide/security-controls/configuring-http-basic-authentication/).
+```nginx
+server {
+    listen 80;
+    listen [::]:80;
+    server_name example.ert.space;
+
+    root /srv/www/example.ert.space;
+    index index.html index.php;
+
+    # set up HTTP basic authentication
+    auth_basic           "Authentication Required";
+    auth_basic_user_file /etc/apache2/.htpasswd;
+
+    location / {
+        try_files $uri $uri/ =404;
+    }
+
+    # process PHP requests
+    location ~ \.php$ {
+        include snippets/fastcgi-php.conf;
+        fastcgi_pass unix:/run/php/php7.0-fpm.sock;
+    }
+
+    location ~ /\.ht {
+        deny all;
+    }
+}
+```
+
+## Reverse proxy
+The URL [example.ert.space](http://example.ert.space) will point to the local [port 8080](http://localhost:8080).
+```nginx
+server {
+    listen 80;
+    listen [::]:80;
+    server_name example.ert.space;
+    location / {
+        proxy_pass http://localhost:8080;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```
