I downloaded the Bitcoin Core daemon on a Ubuntu 16.04 platform from the bitcoin PPA.
sudo apt-get install software-properties-common sudo apt-add-repository ppa:bitcoin/bitcoin Press ENTER to continue sudo apt-get update sudo apt-get install bitcoind
Set up the Bitcoin daemon to auto-run.
Entered these instructions to the file:
[Unit] Description=Bitcoin Server After=network.target After=syslog.target [Install] WantedBy=multi-user.target Alias=bitcoind.service [Service] User=bitcoin Group=bitcoin Start=main service (was a missing = in the original script) ExecStart=/usr/bin/bitcoind ExecStop=/usr/bin/bitcoin-cli stop Restart=always PrivateTmp=false
Looks as if the program has been installedd since I get this output from the following command line:
snerx@snerx:~$ systemctl status bitcoind ● bitcoind.service - Bitcoin Server Loaded: loaded (/etc/systemd/system/multi-user.target.wants/bitcoind.service; bad; vendor preset: enabled) Active: active (running) since Wed 2018-04-18 12:06:30 AEST; 17min ago Main PID: 4283 (bitcoind) CGroup: /system.slice/bitcoind.service └─4283 /usr/bin/bitcoind Apr 18 12:06:30 snerx systemd: Started Bitcoin Server.
That's all well and good. For the time being I'm not interested in downloading a full bitcoin blockchain but it appears that it must be doing so since after the install a full month's worth of bandwidth (200 GB) got eaten up in a 24 h period. And it looks as if something similar is going on still when I fire up my Ubuntu machine. Bandwidth usage has gone from KiB/s to MB/s and is going to drain the household internet budget very rapidly.
What is this Frankenstein monster I have installed?
I have since got an unlimited download internet account and have got a blockchain node up and running. I used the following command to install Bitcoin Core v0.16.0:
$ curl https://bitnodes.earn.com/install-full-node.sh | sh
Downloading the full node using the Bitcoin Core GUI was quite an epic, taking 9 days in total to catch up with 9 years and 18 weeks of blockchains (180GB)--much downtime from internet connection shutting down overnight. At a mere 13.6GB, downloading the full testnet blockchain with the
bitcoind -testnet -daemon command was a much less time consuming proposition.
