## Introduction
|
|
|
|
[Presearch](https://www.presearch.io/) is a community-powered, decentralized search engine that provides better results while protecting your privacy and rewarding you when you search. This weblet deploys a Presearch node. Presearch Nodes are used to process user search requests, and node operators earn Presearch PRE tokens for joining and supporting the network.
|
|
|
|
## Prerequisites
|
|
|
|
- Make sure you have a [wallet](../wallet_connector.md)
|
|
- From the sidebar click on **Applications**
|
|
- Click on **Presearch**
|
|
|
|
## Deploy a Presearch Node
|
|
|
|
|
|
|
|
- Enter an instance name.
|
|
|
|
- You need to sign up on Presearch in order to get your *Presearch Registration Code*. To sign up, go to the [Presearch](https://presearch.com) website, create your account and then head to your [dashboard](https://nodes.presearch.com/dashboard) to find your registration code.
|
|
|
|
- Choose the network
|
|
- `Public IPv4` flag gives the virtual machine a Public IPv4
|
|
- `Planetary Network` to connect the Virtual Machine to Planetary network
|
|
|
|
- `Dedicated` flag to retrieve only dedeicated nodes
|
|
- `Certified` flag to retrieve only certified nodes
|
|
- Choose the location of the node
|
|
- `Region`
|
|
- `Country`
|
|
- `Farm Name`
|
|
|
|
- Choose the node to deploy the Virtual Machine on
|
|
> Or you can select a specific node with manual selection.
|
|
|
|
## Migrate an Existing Presearch Node to the TFGrid
|
|
|
|
Now what if you already have a Presearch node deployed somewhere and would like to migrate to Threefold?
|
|
|
|
We got you! All you need to do is:
|
|
|
|
1. Login to your old server that has your node via SSH.
|
|
2. Run `docker cp presearch-node:/app/node/.keys presearch-node-keys` in order to generate your key-pair.
|
|
3. Head to the *Restore* tab in the Presearch weblet and paste your key-pair in the fields below and you'll be good to deploy!
|
|
|
|
|
|
|
|
After that is done you can see a list of all of your deployed instances
|
|
|
|
|
|
|
|
Now head to your [dashboard](https://nodes.presearch.com/dashboard) again and scroll down to **Current Nodes**, you'll see your newly created node up and connected!
|
|
|
|
|
|
|
|
|
|
## Verify if a 3Node Already Runs a Presearch Workload
|
|
|
|
You can do the following to verify if a Presearch workload deployed without a public IP address already has a Presearch workload running. Note that you will first need to deploy a Presearch workload on the 3Node. After deployment, you can SSH into the VM and do the verification.
|
|
|
|
* SSH into the VM running the Presearch workload
|
|
* ```
|
|
ssh root@<VM_IP_Address>
|
|
```
|
|
* List running containers and identity the Presearch container
|
|
* ```
|
|
docker ps
|
|
```
|
|
* Print the logs of the Presearch container
|
|
* ```
|
|
docker logs <Presearch_container_name>
|
|
```
|
|
* If there is no other Presearch workload running on the 3Node, you will see a similar output:
|
|
* > 2023-10-16T12:18:33.780Z info: Node is listening for searches...
|
|
* If there is another Presearch workload running on the 3Node, you will see a similar output:
|
|
* > 2023-10-16T12:24:00.346Z error: Duplicate IP: This IP Address is already running another Node. Only one Node is permitted per IP Address.
|
|
* If there is another Presearch workload running, you will need to either deploy on another 3Node with a public IP or deploy on another node without a public IP that isn't running a Presearch deployment.
