Installing Dnote Server

This guide documents the steps for installing the Dnote server on your own machine. If you prefer Docker, please see the Docker guide.

Overview

Dnote server comes as a single binary file that you can simply download and run. It uses Postgres as the database.

Installation

Install Postgres 11+.
Create a dnote database by running createdb dnote
Download the official Dnote server release from the release page.
Extract the archive and move the dnote-server executable to /usr/local/bin.

tar -xzf dnote-server-$version-$os.tar.gz
mv ./dnote-server /usr/local/bin

Run Dnote

GO_ENV=PRODUCTION \
OnPremises=true \
DBHost=localhost \
DBPort=5432 \
DBName=dnote \
DBUser=$user \
DBPassword=$password \
WebURL=$webURL \
SmtpHost=$SmtpHost \
SmtpPort=$SmtpPort \
SmtpUsername=$SmtpUsername \
SmtpPassword=$SmtpPassword \
DisableRegistration=false \
  dnote-server start

Replace $user, $password with the credentials of the Postgres user that owns the dnote database.

Replace $webURL with the full URL to your server, without a trailing slash (e.g. https://your.server).

Replace $SmtpHost, SmtpPort, $SmtpUsername, $SmtpPassword with actual values, if you would like to receive spaced repetition through email.

Replace DisableRegistration to true if you would like to disable user registrations.

By default, dnote server will run on the port 3000.

Configuration

By now, Dnote is fully functional in your machine. The API, frontend app, and the background tasks are all in the single binary. Let's take a few more steps to configure Dnote.

Configure Nginx

To make it accessible from the Internet, you need to configure Nginx.

Install nginx.
Create a new file in /etc/nginx/sites-enabled/dnote with the following contents:

server {
	server_name my-dnote-server.com;

	location / {
		proxy_set_header X-Real-IP $remote_addr;
		proxy_set_header X-Forwarded-For $remote_addr;
		proxy_set_header Host $host;
		proxy_pass https://127.0.0.1:3000;
	}
}

Replace my-dnote-server.com with the URL for your server.
Reload the nginx configuration by running the following:

sudo service nginx reload

Configure Apache2

Install Apache2 and install/enable mod_proxy.
Create a new file in /etc/apache2/sites-available/dnote.conf with the following contents:

<VirtualHost *:80>
    ServerName notes.example.com

    ProxyRequests Off
    ProxyPreserveHost On
    ProxyPass / https://127.0.0.1:3000/ keepalive=On
    ProxyPassReverse / https://127.0.0.1:3000/
    RequestHeader set X-Forwarded-HTTPS "0"
</VirtualHost>

Enable the dnote site and restart the Apache2 service by running the following:

a2ensite dnote
sudo service apache2 restart

Now you can access the Dnote frontend application on /, and the API on /api.

Configure TLS by using LetsEncrypt

It is recommended to use HTTPS. Obtain a certificate using LetsEncrypt and configure TLS in Nginx.

In the future versions of the Dnote Server, HTTPS will be required at all times.

Run Dnote As a Daemon

We can use systemd to run Dnote in the background as a Daemon, and automatically start it on system reboot.

Create a new file at /etc/systemd/system/dnote.service with the following content:

[Unit]
Description=Starts the dnote server
Requires=network.target
After=network.target

[Service]
Type=simple
User=$user
Restart=always
RestartSec=3
WorkingDirectory=/home/$user
ExecStart=/usr/local/bin/dnote-server start
Environment=GO_ENV=PRODUCTION
Environment=OnPremises=true
Environment=DBHost=localhost
Environment=DBPort=5432
Environment=DBName=dnote
Environment=DBUser=$DBUser
Environment=DBPassword=$DBPassword
Environment=DBSkipSSL=true
Environment=WebURL=$WebURL
Environment=SmtpHost=
Environment=SmtpPort=
Environment=SmtpUsername=
Environment=SmtpPassword=

[Install]
WantedBy=multi-user.target

Replace $user, $WebURL, $DBUser, and $DBPassword with the actual values.

Optionally, if you would like to send spaced repetitions throught email, populate SmtpHost, SmtpPort, SmtpUsername, and SmtpPassword.

Reload the change by running sudo systemctl daemon-reload.
Enable the Daemon by running sudo systemctl enable dnote.`
Start the Daemon by running sudo systemctl start dnote

Configure clients

Let's configure Dnote clients to connect to the self-hosted web API endpoint.

CLI

We need to modify the configuration file for the CLI. It should have been generated at ~/.config/dnote/dnoterc upon running the CLI for the first time.

The following is an example configuration:

editor: nvim
apiEndpoint: https://api.getdnote.com

Simply change the value for apiEndpoint to a full URL to the self-hosted instance, followed by '/api', and save the configuration file.

e.g.

editor: nvim
apiEndpoint: my-dnote-server.com/api

Browser extension

Navigate into the 'Settings' tab and set the values for 'API URL', and 'Web URL'.
