Configure Nginx proxy and HTTPS. The operating system here is Ubuntu.

## Installing Nginx

Download Nginx and remove Apache2

    sudo apt-get install nginx
    sudo apt-get remove apache2

## Build the configuration file

1. First, create the configuration file:

       cd /etc/nginx/conf.d
       vim default.conf

2. Fill the file with the context shown below, part of the setting show be changed. Then you can enjoy your web with HTTPS forced and proxy.

       # This part configures, where your Trilium server is running
       upstream trilium {
         zone trilium 64k;
         server 127.0.0.1:8080; # change it to a different hostname and port if non-default is used
         keepalive 2;
       }

       # This part is for proxy and HTTPS configure
       server {
           listen 443 ssl;
           server_name trilium.example.net; #change trilium.example.net to your domain without HTTPS or HTTP.
           ssl_certificate /etc/ssl/note/example.crt; #change /etc/ssl/note/example.crt to your path of crt file.
           ssl_certificate_key /etc/ssl/note/example.net.key; #change /etc/ssl/note/example.net.key to your path of key file.
           ssl_session_cache builtin:1000 shared:SSL:10m;
           ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
           ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
           ssl_prefer_server_ciphers on;
           access_log /var/log/nginx/access.log; #check the path of access.log, if it doesn't fit your file, change it

           location / {
               proxy_set_header Host $host;
               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 $scheme;
               proxy_set_header Upgrade $http_upgrade;
               proxy_set_header Connection "upgrade";
               proxy_pass http://trilium;
               proxy_read_timeout 90;
           }
       }

       # This part is for HTTPS forced
       server {
           listen 80;
           server_name trilium.example.net; # change to your domain
           return 301 https://$server_name$request_uri;
       }

## Serving under a different path

Alternatively if you want to serve the instance under a different path (useful e.g. if you want to serve multiple instances), update the location block like so:

- update the location with your desired path (make sure to not leave a trailing slash "/", if your `proxy_pass` does not end on a slash as well)
- add the `proxy_cookie_path` directive with the same path: this allows you to stay logged in at multiple instances at the same time.

        location /trilium/instance-one {
            rewrite /trilium/instance-one/(.*) /$1  break;
            proxy_set_header Host $host;
            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 $scheme;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_pass http://trilium;
            proxy_cookie_path / /trilium/instance-one
            proxy_read_timeout 90;
        }

## Configuring the trusted proxy

After setting up a reverse proxy, make sure to configure the Trusted proxy.
