prunednode.today

A website and sync script for prunednode.today.

How to set up:

• download and install latest bitcoin core from bitcoincore.org
• copy bitcoin.conf to your ~/.bitcoin folder (create if not present) - it is set up to use prune=550 flag.
• start bitcoind --daemon and wait for full sync
• install nginx and copy content of the html folder to /var/www/html/
• create the first snapshot (see below)
• adjust index.html - update the author, url to

Nginx configuration

Add the following lines to the server block of nginx, so latest.zip and latest.signed.txt redirect to the latest snapshot:

server{
	# ...
	rewrite ^/latest.zip$ /snapshot221003.zip redirect;
	rewrite ^/latest.signed.txt$ /snapshot221003.signed.txt redirect;
	# ...
}

You will need to update it every time you create a new snapshot and reload nginx (nginx -s reload)

Creating a snapshot

1. Run zipit.sh script, it will:
   • stop bitcoind and wait for 1 minute
   • copy bitcoin files to a separate folder
   • start bitcoind again to continue syncing
   • zip the content of the folder to a snapshot<date>.zip
   • create a snapshot<date>.txt with sha256 of the file
   • move it to the /var/www/html/ folder
2. Sign the snapshot<date>.txt with your pgp key using gpg --output snapshot<date>.signed.txt --clearsign snapshot<date>.txt and place it next to the snapshot zip file
3. Update:
   • nginx config file to use new snapshot for redirects
   • /var/www/html/latest.txt so it contains the name of the latest snapshot zip file
   • /var/www/html/index.html so it has correct date in the description

It is not necessary to run the node on the same machine where the snapshots are hosted, you can always create a snapshot on another machine and rsync files to the host.
