Topic: How to run your own P2Pool in Ubuntu 14.04 LTS with merged mining - page 5. (Read 54246 times)

###############################################################################
# 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.

# Download the bitcoin bootstrap file. This saves a massive amount of time when starting bitcoind the first time - literally days.

# Details: https://bitcointalk.org/index.php?topic=145386.0  (Check here for more recent versions every few months.)
