Haven't gone through the whole post yet but I think this is/was EXACTLY what I was looking for- an updated and easy way to setup a p2pool.

I'll start working on this now Wink

good to see more and more p2pool nodes getting set up, best luck with yours waldohoover  Smiley

I'm happy to see people wanting to support the network as well and move towards p2pool, thanks Smiley

Setting up the node (in my sig) wasn't too bad with Morblias initial guidance but I def want to get a pool going now. I run /r/TeamRedditMining on reddit and would love to have our own pool going.  Smiley

aha! a US node, i'll direct US friends to it.. my node is also in my sig (Central Cavern - which is an Amsterdam node) - but be careful, the page is noisy  Cheesy

Very nice and thank you!

No harm in making mining a bit of fun, and since murdof did hold my hand rather a lot in setting up that node, credit should go to him; he's taught me loads over the past couple of days... my only linux work previously was setting up nodes for coins - what I really want to do is get my head around DGM. Always mined on small DGM pools up 'til now and I'd love to be able to know the ins and outs of it - even if I don't essentially set up a DGM pool, it's all learning huh?

A few months ago, I was working on a script that would automate the installation and rollout of a VPS with a bitcoind full node and a p2pool install. I never got it finalized with all the bells and whistles that I wanted, nor really polished, but it was good enough that I was able to adapt it for my local and remote p2pool installs, with some obvious changes. I'm posting it here in the hope you (or others) find it useful. I'd encourage you to scavenge whatever bits you can incorporate into your already-excellent guide.

Code:
###############################################################################
# Prerequisites
###############################################################################
#
# Before you run this, do the following:
#   * Log in as root
#   * Be in your home directory
#   * The parent of home directories has to be specified below (e.g., if user home directories are like /home/user1, then HOME_ROOT must be set to /home).
#
#   * (Optional but recommended) Create a file with the name specified below in REGULAR_USER_PUBLIC_KEY_FILE that contains your SSH public key.  This should be in the copy/paste format you get from PuttyGen, not the saved public key file.

# Assumptions:
#   * Running on a relatively recent version of Ubuntu (12.04 or later) -- not tested with anything else, but it might work anyway!
#   * Python is already installed. If not, the script attempts to install Python, but right now I can't guarantee if you'll get Python 2.7 or 3.x.  P2Pool doesn't work with 3.x.
#   * This script was designed for use on a VM or VPS that's basically empty, and only has the root user created.

EDIT 2014-06-20: I just noticed that the download of the blockchain file was disabled. That's because I was futzing around with the script the last time I used it, and I forgot to re-enable that line. Sad It's corrected now.

breakthrough moment.

I used to get all confused and dizzy when I looked at code. scanning through that box, Kyros, it would seem I may very well have 'learned a new language'
I'll devote some time over the weekend to look into this in more depth.

This is also very help and really great, thanks for the contribution!

(Were you the guy who posted something similar about this on reddit?)
No, but I remember that post. It inspired me to create this script, and in fact, the section for setting up the bitcoin configuration file was adapted from that post.

Good stuff Kyros!

I don't have in the guide any information about firewalling - so I guess this could be in the extras.
I did add rpcallow=127.0.0.1 - but still people could find an exploit to that - so firewalling will be the best way to go.

What I understand is that people want to just get on a Linux box and just type 2 commands and set up everything.
I don't think that people prefer to build things (I don't personally but I have to).
So that's why I went with the binaries and a mini script to execute all the commands to have you up and running ASAP.
I have tried the script in 3 scenarios already and works great.
The only thing that I found is that when tar extracts some files are created with root as owner. Maybe I'm missing a tar option to use current user? Haven't checked.

All in all I invite you to try it out the 2 line script (you can just wget the script and check the contents) and let me know what you think.

huntercoin is fixed and compiles ok

still though downloading the blockchain so haven't tried it (for some reason downloading is very slow)

so when it has finished and i confirm it works with merge mining I will add it to the guide.

Hey murdof... just wanted to say good job on this - especially the "Lazy Man's" version.  Personally, I hacked my way through setting everything up (Disclaimer: I have everything running natively on OSX Mavericks).  The work you've done to compress the installation on Ubuntu 14.04LTS down to two commands is impressive.  Nicely done!

Something I just noticed:

Install Ubuntu 14.04 LTS Server from here: http://www.ubuntu.com/download/server
(note do not install Ubuntu 14.04 LTS - you need Server version for text only install)

I think in the second sentence, you meant to say, "do not install Ubuntu Desktop 14.04 LTS" -- but either way, this setup should work just fine even on a Desktop install of Ubuntu. You'd just need more disk space for the graphical stuff. In the past, I've run plenty of server-type software (including bitcoind and p2pool) on the Desktop versions of Ubuntu.

I'll spin up a VM with Ubuntu Desktop 14.04 installed and see how the script runs.

Thanks Kyros,

fixed.

I don't think there is a point to run a server with GUI.
Some people might want to run it on their main desktop on the other hand - so yes it would be good to know if you tried it and worked.
Normally it should work ok.

I'm running with 4GB and it utilizes about 2.5GB.
Huntercoin is something that takes up all CPU + Memory so I stopped it cause anyway I found it useless. Too slow and too many resources.

While memory used to be more expensive, it is stil nice to know what the actual requirements are.

I would therefore think it is fair to say that you should get away with a 3 GB Ram VPS safely.

Most VPS providers allow you to exceed the allocated memory by atleast 10-20% anyway Wink

Totally passed up the idea of a VPS concept.. good point.. though i like to keep my memory on a even number Smiley call me old fashioned. 4GB Ram would be ideal and yes I have run it on a vps at 4GB and no problems.. course it was for litecoin

The only reason I stay away from VPS is i want something local. Local is always the best results with p2pool shares

definitely, 100% agree, unfortunately I don't have the ability to run a local node, so VPS is a good option for folks like me.
and with murdof's guide and how-to, those who can, can, and those who can't, can too!

Since i have no done it with bitcoin on a VPS.. how are the results? Are you seeing a lot more stales/DOA?
