Running your own Dojo server is essential for those wanting to utilise the privacy benefits achieved through Samourai Wallet’s post-mix spending tools and powerful Whirlpool CoinJoin implementation.
SSH into your node and go to your downloads directory.
cd ~/downloads
Next, download the latest version of Dojo from the official Samourai Dojo repository, using the following command.
wget https://code.samourai.io/dojo/samourai-dojo/-/archive/master/samourai-dojo-master.zip
Now unzip the downloaded Dojo archive.
unzip samourai-dojo-master.zip
Once the archive is unpackaged, create a new directory and move the unpackaged files across.
mkdir ~/dojo-app
mv ~/downloads/samourai-dojo-master/* ~/dojo-app/
The archive is no longer required and can be safely removed, as well as the empty folder.
rm -r samourai-dojo-master/
rm samourai-dojo-master.zip
Next, you must edit multiple configuration files before Dojo can be initialised.
cd ~/dojo-app/docker/my-dojo/conf/
nano docker-bitcoind.conf.tpl
Edit the file as follows;
####edit to your core rpc username & password BITCOIND_RPC_USER=dojorpc BITCOIND_RPC_PASSWORD=dojorpcpassword ####change BITCOIND_INSTALL=on ##to BITCOIND_INSTALL=off ####edit to your nodes IP BITCOIND_IP=172.28.1.5 ####change BITCOIND_RPC_PORT=28256 ##to BITCOIND_RPC_PORT=8332 ####change BITCOIND_ZMQ_RAWTXS=9501 ##to BITCOIND_ZMQ_RAWTXS=28333 ####change BITCOIND_ZMQ_BLK_HASH=9502 ##to BITCOIND_ZMQ_BLK_HASH=28334
Save and exit the file.
In the next file, you can choose whether or not to install the Bitcoin RPC Explorer. Since we installed Mempool Explorer in the previous guide, I will disable it; however, the choice is yours. If you want to disable it, follow the next step; otherwise, skip to the following step.
nano docker-explorer.conf.tpl
Edit the file as follows;
####change EXPLORER_INSTALL=on ##to EXPLORER_INSTALL=off
Save and exit the file.
nano docker-indexer.conf.tpl
Edit as follows;
####change INDEXER_TYPE=addrindexrs ##to INDEXER_TYPE=fulcrum ####edit to your nodes IP INDEXER_IP=172.28.1.6 ####change INDEXER_RPC_PORT=50001 ##to INDEXER_RPC_PORT=50002 ####change INDEXER_BATCH_SUPPORT=inactive ##to INDEXER_BATCH_SUPPORT=active ####change INDEXER_PROTOCOL=tcp ##to INDEXER_PROTOCOL=tls
Save and exit the file.
nano docker-mysql.conf.tpl
You need to add a MySQL root and user password to this file. Use a password generator and ensure you back them up securely. I recommend avoiding the use of special characters.
####add your new passwords here MYSQL_ROOT_PASSWORD=rootpassword MYSQL_PASSWORD=password
Save and exit the file.
nano docker-node.conf.tpl
You need to generate another three passwords, again avoiding special characters, and back them up safely. The admin key is of particular importance since it’s required whenever accessing your Dojo’s backend GUI, the Dojo maintenance tool.
Edit the following fields to include the new passwords.
NODE_API_KEY=myApiKey NODE_ADMIN_KEY=myAdminKey NODE_JWT_SECRET=myJwtSecret
In the same file, edit as follows.
####change NODE_ACTIVE_INDEXER=local_bitcoind ##to NODE_ACTIVE_INDEXER=local_indexer
In this file, you also have the option to enable Auth47, allowing you to log into your maintenance tool using your BIP47 payment code. This adds a QR code to the login page, which can be scanned from inside your Samourai Wallet to authenticate.
Whilst completely optional, to enable Auth47, simply paste your BIP47 payment code, starting with “PM8T“, next to the following line.
NODE_PAYMENT_CODE=
Save and exit the file. You are now ready to initialise your Dojo.
cd ~/dojo-app/docker/my-dojo
./dojo.sh install
Your Dojo will begin the installation process. Once you start to see a constant stream of “node.js” logs, the installation is complete, and you can exit the logs with “control+c“.
Your Dojo will now begin to synchronise. To check its status, you will need access to your Dojo Maintenance Tool, commonly referred to as “DMT“.
The DMT is accessed via the Tor Browser, using your Dojo’s randomly generated onion address and the node admin key you created previously. You can find the onion address by running the following command within the same directory.
./dojo.sh onion
Bookmark this onion address for future reference. Once you see a full house of green status checks on your dashboard, you’re ready to pair your Samourai wallet. You will find a “Pairing” menu option to the left, which is where you can find your pairing QR code, which you can scan when prompted during the initial setup steps of creating a Samourai Wallet.
If you previously chose to install the “RPC Explorer“, you will notice that there are two QR codes displayed. The one to the left is your pairing QR.
If you already have an active Samourai Wallet, you must reset the wallet, ensuring that you test your backup file first. You can then recover your wallet using your wallet’s passphrase and backup file, scanning the pairing QR during initialisation.
If a previous Dojo connection is detected in your backup file, you will be asked whether you want to use the newly scanned node or the one that was in use when the backup file was created. Select “Yes” at this prompt to pair with your new Dojo. You can find more detailed guides within Samourai’s documentation pages.
In the next article, we will install Samourai Wallet’s Whirlpool CLI.
