Skynet Portal Setup Scripts

This directory contains a setup guide and scripts that will install and configure some basic requirements for running a Skynet Portal. The assumption is that we are working with a Debian Buster Minimal system or similar.

Initial Setup

(Assumes we are logged in as root on a fresh installation of Debian)

You may want to fork this repository and add your ssh pubkey to authorized_keys and optionally edit the tmux and bash configurations.

SSH in a freshly installed Debian machine.
apt-get update && apt-get install sudo
adduser user
usermod -a -G sudo user
Quit the ssh session.

You a can now ssh into your machine as the user user.

On your local machine: ssh-copy-id user@ip-addr
On your local machine: ssh user@ip-addr
Now logged in as user: sudo apt-get install git
git clone https://github.com/NebulousLabs/skynet-webportal
cd skynet-webportal/setup-scripts
./setup.sh
Once DNS records are set you can run: ./letsencrypt-setup.sh
This should edit your nginx configuration for you. If not, you should check that keys were created by letsencrypt in /etc/letsencrypt/live/ and add the following lines into your nginx configuration. Make sure to replace YOUR-DOMAIN with your domain name.
```
ssl_certificate /etc/letsencrypt/live/YOUR-DOMAIN/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/YOUR-DOMAIN/privkey.pem;
```
Finally make sure to check your nginx conf and reload nginx: sudo nginx -t sudo systemctl reload nginx

Running siad

NOTE: You must be running siad and siac by building from a version at least as recent as v1.4.3.

You still need to setup siad for the backend to be complete.

The setup script creates a systemd user service that will run siad in the background and automatically restart upon failure. The siad.service file must be placed in ~/.config/systemd/user/

To use the siad.service, first fill out ~/.sia/sia.env environment variables with the correct values. You will need to initialize your wallet if you have not already done so.

To enable the service: systemctl --user enable siad.service

Useful Commands

To start the service: systemctl --user start siad To stop it: systemctl --user stop siad To check the status of it: systemctl --user status siad

To check standard err/standard out: journalctl --user-unit siad

Portal Setup

When siad is done syncing, create a new wallet and unlock the wallet.

Then set an allowance (siac renter setallowance), with the suggested values below:

10 KS (keep 25 KS in your wallet)
default period
default number of hosts
8 week renewal time
500 GB expected storage
500 GB expected upload
5 TB expected download
default redundancy

Once your allowance is set you need to set your node to be a viewnode with the following command: siac renter setallowance --payment-contract-initial-funding 10SC

Now your node will begin making 10 contracts per block with many hosts so it can potentially view the whole network's files.

Running the Portal

Make sure you have nodejs and yarn installed. You can check that with node -v and yarn -v commands respectively.

run cd /home/user/skynet-webportal
run yarn to build dependencies
run yarn build to build the client package

Client package will be outputted to /public and nginx configuration will pick it up automatically.
