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.
