⚙️Node Setup Instructions
Get your node up and running in just a few minutes on your computer.
We're excited to have you be a part of the future of search. Tens of thousands of nodes are already being operated by Presearch node operators and these nodes provide the infrastructure for the main Presearch search experience, which can be searched via: https://presearch.com
General assumptions
Running a node is recommended on computers powered on 24/7 due to uptime score statistics.
Installation or management of a node can be done over any operating system (Windows, Mac, Linux, other of your choice) as long as you can access the underlying docker application
There is no limit for number of nodes one account could operate
There is no preferred setup as the main goal of the project is to support decentralization
Installation options
If you have any questions, you can join our helpful nodes telegram group or discord #node.
Before you continue the node setup process, it is good to decide where your node would be running. Typical setups are following:
VPS - Virtual Private Server runnng Linux operating system directly utilizing native Docker application
Cons - can be costly, need to select a cost-friendly provider or free-tier service
Pros - runs within cloud or datacenters, no electicity bills
Home computer running Windows or Mac operating system with Docker Desktop application
Cons - computer needs to be running 24/7, electricity bills, utilizes your network
Pros - can be executed almost immediately,
PREberry (or Raspberry Pi models 3 or 4)
Cons - utilizes your network
Pros - minimal power consumtion
Decentralized container solution like ThreeFold.io with prebuilt Presearch nodes
Cons - harder to obtain, limited support from Presearch
Pros - inovative, decentralized, less costly, no electricity bills
Required toolset
If you prefer to use your home computer, installation is done locally
Windows - Powershell or Command Line
Mac - Terminal or any other console application
Linux - Console or any other similar application
If you prefer to use VPS machine, installation is done over SSH client application
Windows - Putty or any other of your choice
Mac - Terminal or any other of your choice
Linux - Console or any other of your choice
Presearch Tutorial
Please refer to the subchapter dedicated for each type of installation:
Setup Nodes Trough VPS
Running a Node on Oracle Cloud Infrastructure
Generic setup steps
1. Install Docker [Linux/PREberry] or Docker Desktop [Windows/Mac] on your target machine of your choice (see the options above)
2. Get your node registration code at https://nodes.presearch.com/dashboard.
3. Run the node start commands below in your terminal to install your node [ See tutorials for how to open terminal on Mac & Windows ]
Copy/Paste the operating-system-specific command below into your terminal:
docker stop presearch-node ; docker rm presearch-node ; docker stop presearch-auto-updater ; docker rm presearch-auto-updater ; docker run -d --name presearch-auto-updater --restart=unless-stopped -v /var/run/docker.sock:/var/run/docker.sock presearch/auto-updater --cleanup --interval 900 presearch-auto-updater presearch-node ; docker pull presearch/node ; docker run -dt --name presearch-node --restart=unless-stopped -v presearch-node-storage:/app/node -e REGISTRATION_CODE=$YOUR_REGISTRATION_CODE_HERE presearch/node ; docker logs -f presearch-node
IMPORTANT: You need to insert your registration code from step #2 above into the script by replacing the text$YOUR_REGISTRATION_CODE_HEREwith your actual registration code. So, for example, if your registration code is XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX then the final command would contain the text REGISTRATION_CODE=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX .
The above command installs two services on your computer, the presearch-node and the presearch-auto-updater, and configure both of them to be always running in the background.
The presearch-node actually runs the decentralized search software, whereas the presearch-auto-updater is responsible for automatically upgrading the presearch-node to the newest versions when released to ensure the node stays up to date and can continue to connect to the Presearch network.
Common issues
Executig installation under wrong environement
Using Linux / Mac / Windows - Powershell commands under Windows - Command Line and vice-versa
Typo with registration code
Ensure you are using the registration code and not the API key
No blank space between = and the code itself
Be sure to remove the $ right after =
Use the full registration code, do not omit any characters
Include the entire installation instruction (e.g., include "presearch/node" after the code)
Running Searches
Keep an eye on the running node output and you’ll eventually see incoming searches (“Success! ...”). You can run searches yourself at https://presearch.com, though keep in mind these will be distributed across all nodes in the Testnet, not just yours.
Managing your Node
The command in the setup instructions configured your node to run as a background service. This means you can close your terminal and it will continue running as long as your system is up and haven't manually stopped your node.
If you would like to see the output of your node at any point you can run the following command:
See current node output:
docker logs -f presearch-node
To stop your node and the presearch-auto-updater manually, run the following commands in your terminal:
Manually stop your node:
docker stop presearch-node
docker stop presearch-auto-updater
To restart a manually-stopped node, run the following command:
Restart your stopped node:
docker start presearch-auto-updater
docker start presearch-node
If you would like to see if your node or the presearch-auto-updater are running, run the following command:
Check if the node services are running:
docker ps
Finally, if you run into any problems with your node, you can always run the installation script again from the setup instructions section if needed. Your node identity will be preserved, but should will get your node upgraded, reinstalled, and over most configuration issues you may encounter.
Hardware Specification
Docker image is only for 64bit architectures like x64 / ARM64 based CPU's for now.
Raspberry Pi Models 3/4 are also supported when running the 64-bit Raspberry Pi operating system.
Nodes were successfully installed on VPS machines with minimal resources:
1 CPU
768 MB RAM (under minimized OS editions even 512 MB RAM)
10 GB storage
100+ Mbit network link
Running Multiple Nodes
You are more than welcome to run as many nodes as you would like under your Presearch account. You can reuse the same Registration Code to launch each node, subject to the following limitations:
You may only run one node per server at a time. Presearch will only allow one connection per public IP (v4) address at the same time, so if you want to disconnect a second node from the same IP address you’ll need to stop the other node first. IPv6 addresses are currently not supported.
You must include a valid Registration Code on the first run of each node to initialize it and attach it to your Presearch account. When the node software runs for the first time, it creates a public/private key pair to uniquely identify your node on subsequent requests.
You can optionally change your Registration Code at any time by clicking "Generate Replacement Code" on the Nodes Dashboard. Any prior nodes initialized with the old Registration Code will continue to work, but the old code will no longer be able to initialize any new nodes.
You may not run the same node simultaneously on multiple servers. If you initialize a node and then copy the initialized node to another server (which transfers the node’s unique public/private key identifiers), this creates a copy of the same node identity on both servers. If you try to run both at the same time, the Presearch Engine will reject the second one until the first disconnects.
