Click here to download ConnectorDB Server.

If you want to set up an internet-connected server, a VPS provider such as DigitalOcean is recommended. This tutorial assumes that you have already set up a server.


To start off, you need to make sure that you have all of the necessary dependencies. ConnectorDB needs recent versions of both Postgres and Redis installed:

sudo apt-get install postgresql redis-server

The servers are managed by ConnectorDB, so you do not need them to be run on startup:

sudo systemctl disable postgresql.service
sudo systemctl stop postgresql.service
sudo systemctl disable redis-server.service
sudo systemctl stop redis-server.service

Next, download the ConnectorDB binaries. Only 64 bit linux is supported at this time.

wget -O connectordb.tar.gz
tar -zxvf connectordb.tar.gz

Finally, make sure that connectordb is working: $ cd ./bin $ ./connectordb --version
ConnectorDB 0.3.0b1

arch: linux/amd64
go: go1.7
git: 209f1335b95aa115c57642c06f896e03b68d637c
build: 2016-09-06_07:29:26AM

Usually, processes can’t access lower ports (such as 443 or 80). To let ConnectorDB access these ports, you will need to run the following command:

sudo setcap cap_net_bind_service=+ep connectordb

All of the files in the binary folder are required for proper operation. You should move this folder somewhere where it won’t bother you, and add it to your PATH.

mv ./bin ~/.connectordb

Add the following to your .bashrc:

export PATH=$PATH:~/.connectordb

Setting up an Encrypted Folder

ConnectorDB will be holding very personal data, so it is important to take some basic security precautions. If you will be providing your own encryption, or just want to play around, feel free to skip this step.

ConnectorDB does not come with built-in encryption support, but you can use a basic python2 script called cryptify, with which you can set up an encrypted password-protected container for your ConnectorDB database.

apt-get install python-subprocess32 cryptsetup
wget -O cryptify
chmod +x cryptify

With this script, you can create a 10GB container for your database, saved as mydatabase.crypt, and mounted in folder mydatabase with the following command:

./cryptify -i mydatabase.crypt -o mydatabase -s 10000 create

On future reboots, you can run ./cryptify -i mydatabase.crypt -o mydatabase open to mount your folder, and ./cryptify -i mydatabase.crypt -o mydatabase close to dismount.

Creating a Database

Now it is time to create a ConnectorDB database:

connectordb create mydatabase/db

The above command will create all the files necessary to run your ConnectorDB server in mydatabase/db.

Configuring ConnectorDB

When starting or running, connectordb loads all of the necessary information from a JSON-formatted configuration file.

To see the file, you can navigate to your database directory, and open connectordb.conf

vim mydatabase/db/connectordb.conf

Before you can successfully run ConnectorDB on your server, you will need to edit a couple options. Only the options that need editing are shown below:

  // This option needs to be set for ConnectorDB to work on the internet. If you don't
  // have a domain name (such as when running on a local Raspberry Pi), you can use
  // the IP address instead:
  "siteurl": "",

  // When running behind a reverse proxy (such as caddy or nginx), you can leave this
  // value at the default. If you want ConnectorDB to be secure, make sure to run
  // it on port 443 (if running without a domain name, you will either have to use port 80 or
  // generate your own https certificates)
  "port": 443,
  // Since we're running on port 443 (https), we redirect port 80 (http).
  "redirect80": true,

  // Make sure that ConnectorDB is exposed to the internet
  "hostname": "",

  // ConnectorDB can generate its own Let's Encrypt TLS certificates, so that nobody
  // can snoop on your data. Change the following values to enable Let's Encrypt support.
  "tls": {
    "enabled": true,
    "acme": {
      "enabled": true,
      "domains": [
      // You must agree to the Let's Encrypt terms of service
      "tos_agree": true

Creating a User

With ConnectorDB all set up, you can add all of your users by running with join enabled:

connectordb start mydatabase/db --join

You can now use your browser to add as many users as you want by navigating to

Once all users are added, you should stop ConnectorDB to disable join mode:

connectordb stop mydatabase/db

Running ConnectorDB


connectordb start mydatabase/db


connectordb stop mydatabase/db

Encrypted folder

Remember that you will have to decrypt your database folder each time you restart:

./cryptify -i mydatabase.crypt -o mydatabase open


You can perform a backup of your entire ConnectorDB database on a running server by running this command:

connectordb export mydatabase ./exportfolder
