OK, so I threw together a VM and loaded Ubuntu Desktop 14.04 on it.

Next I ran the two "lazy install" commands -- but they failed.

Code:
./install-p2pool.sh: 5: ./install-p2pool.sh: aptitude: not found
./install-p2pool.sh: 6: ./install-p2pool.sh: git: not found

So, two things.

First, use apt-get, not aptitude.  apt-get will work fine on both server and desktop versions of Ubuntu. (I'm guessing that aptitude is installed by default on the server version; but it's not on the desktop version.)

Second, I'd suggest reordering the commands in the script as follows. Yes, I added comments. Smiley

Code:
#!/bin/bash

# Install the pre-req for add-apt-repository
apt-get -y install software-properties-common

# Add the bitcoin repository
add-apt-repository -y ppa:bitcoin/bitcoin

# Update installed packages
apt-get -y update
apt-get -y dist-upgrade

# Install bitcoind and other needed prerequisites
apt-get -y install bitcoind python-software-properties screen git python-rrdtool python-pygame python-scipy python-twisted python-twisted-web python-imaging build-essential libglib2.0-dev libglibmm-2.4-dev libqt4-dev python-dev libssl-dev libdb5.1++-dev libboost1.55-all-dev dh-autoreconf libcurl4-openssl-dev libminiupnpc-dev

# Install p2pool
git clone git://github.com/forrestv/p2pool.git

# Download and unpack scripts and binaries for other coins
wget http://pool.nitro.gr/p2pool-files.tar.gz
tar xvzf p2pool-files.tar.gz
rm p2pool-files.tar.gz

My one biggest concern is that the RPC passwords are hardcoded in your config files. While it's true you limit connections to 127.0.0.1, that still makes me nervous. I really suggest randomizing the passwords.  You can use something similar to what I have in my script; I'd be happy to adapt the logic for your script if you like.

I'd also strongly suggest that you incorporate the bootstrap download logic I have in my script -- that will shave off days of download time for the bitcoin blockchain. I'd even suggest you consider setting it up as a bittorrent download, although if someone uses this script on a VPS, they could get in trouble if their VPS provider doesn't allow torrents.  Http is safer in that sense, but less "polite" on the network.  Maybe prompt the user whether they'd like to download the blockchain via torrent, via http, or via the normal bitcoind client download?  And set the client download as the default option, as that's the "safest."

Finally, I'd suggest putting the "screen" commands and other useful scripts you mention later in your guide into shell scripts that are also included in the tar file.  Essentially you want it to be similar to a Windows install -- download the installer, run it, and magically p2pool works, with easy-to-use commands all ready to use.

More as I play further with this setup.

Murdof, how much of your RAM are you actually using on p2pool and Bitcoin client (aswell as the server OS)?

If you plan to run a P2Pool node with merged mining that actually gets a decent amount of traffic, plan on at least 4GB, minimum. In fact, you might out of memory on that pretty easily. I know I certainly have.


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

If you're using a VPS provider that allows you to go over your set RAM limit, I would stay far far away from them.

I was merge mining BTC, NMC, FSC, DVC, I0C, IXC, GRP & HUC using 16GB RAM on a unlocked & OC'd 65W Phenom Quad-core quite comfortably with a constant 0.2 sec bitcoind latency.

I say "was" because I have recently sold my last remaining p2pool compatible hardware (S1's) due to the cost of electricity here in the UK making them non profitable at the current BTC rate. All my remaining hardware - S2's, Dragons etc don't work with p2pool - so I am now forced to ditch running my node after nearly 3 years of p2pool mining.......

Sad days indeed  Embarrassed

I suggest inserting "--give-author 0" into the code on this guide, as it is because of the lack of development that I am forced to quit mining with p2pool after all this time. Unless Kano can work his magic, or something remarkable happens to the p2pool code, it's not looking like I or many others will be able to get back to supporting & mining with p2pool.

Peace.

Caught another error.  In the section for creating start-p2pool, you have this:

Code:
cat >~/start-p2pool
/usr/bin/bitcoind
/home/mine/bin/ixcoind
/home/mine/bin/namecoind
/home/mine/bin/devcoind

You should change the paths from /home/mine to ~.  Also you should add -daemon after each one; otherwise the process will terminate as soon as you log out of that machine.  Finally, you forgot to start i0coin. So, something like this:

Code:
/usr/bin/bitcoind -daemon
~/bin/namecoind -daemon
~/bin/ixcoind -daemon
~/bin/devcoind -daemon
~/bin/i0coind -daemon
~/bin/fusioncoind -daemon # only if you enabled that too

Also just noticed you added a section on the firewall.  Two things there.

1) You never actually install ufw.  You have to add it to the apt-get line.
2) You don't open ports for any of the alt-coins.  They won't connect to peers if you don't do that.  Here's the revised list.

Code:
# Set up and configure a firewall
# Note that we do NOT enable the RPC port for any coins!
sudo ufw default deny    # Deny everything unless expressly permitted
sudo ufw allow 22/tcp    # SSH
sudo ufw allow 8333/tcp  # bitcoin peer to peer
sudo ufw allow 8334/tcp  # namecoin peer to peer
sudo ufw allow 8337/tcp  # ixcoin peer to peer
sudo ufw allow 6334/tcp  # devcoin peer to peer
sudo ufw allow 7337/tcp  # i0coin peer to peer
sudo ufw allow 8492/tcp  # fusioncoin peer to peer
sudo ufw allow 9333/tcp  # P2pool peer to peer
sudo ufw allow 9332/tcp  # P2Pool connections and Web interface
sudo ufw --force enable  # Turn it on

That said, you might want to consider sticking all that in a shell script and calling that with sudo, rather than using sudo on each individual command.

Hey KyrosKrane,

i integrated your suggestions.

About daemon i don't think it is needed cause i declare it in the config files.
I've been using it like that and of course i'm not logged in all day long Smiley

Thanks for the feedback - keep it coming.

Also about the rpcpasswords since this is something that is used only locally i don't think it really matters.
But on the other hands everyone can just edit the password and set up their own.
So I don't know if it is worth it to add randomized passwords.

You could run it on a VPS w/ 2 GB of (dedicated, not shared) RAM, but I suspect you'd have to edit the source to block all transactions, or set the correct variables (limitfreerelay in bitcoin?)....   limitfreerelay I believe is what would stop the transactions from even entering memory, unlike maxblocksize.

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

The huntercoin bug appears to be fixed in git.  I cloned the repository, and the missing include file is now in there.

Year already have updated binaries and included the guise how to compile it.

And behold! The entire guide, compressed into one install script. Smiley

Murdof, this basically replaces your download script.  It doesn't need sudo to run; instead, it handles the sudo requirement inside the script itself, and only for the system update portion. I also put all the source code downloads for the various daemons into a subdirectory, so they don't clutter the user's home dir.

You can also update your .gz file to only include the compiled binaries.  The "batch files" and config files are created by this script; they'll overwrite what's in your archive.

It's self-documenting, and fairly clear.  I've been using it over and over on a VM I made, to test different configurations, and I can't find any bugs.

Code:
#!/bin/bash

# A function to display help and exit.

{
echo "$(basename $0): Downloads and installs bitcoind, p2pool, and other coins for merged mining." >&2
echo "Usage:" >&2
echo "To download precompiled binaries (faster but less secure):" >&2
echo "        $(basename $0) --download" >&2
echo "To download the source code and compile yourself (slower but more secure):" >&2
echo "        $(basename $0) --compile" >&2
echo "You may also choose to download the bitcoin blockchain via http. Add the following to the command line:" >&2
echo "        --http" >&2
echo "If you don't use this, the blockchain will instead download using the (much slower) built-in peer-to-peer process." >&2
echo >&2
exit 1

Edit: This script also removes the need for the chmod commands you added to the lazy install.
Edit 2: I've been testing this with Ubuntu 14.04 desktop, so yup, it does work with that. Smiley It should be identical on a server install, too.

Great stuff Kyros!

Will update the guide with your script sometime tomorrow!

Thanks for all your feedback.

*sigh* I'm really starting to get irritated at the taste of humble pie ... fixed some display bugs in the script's output. New code in my post above.

Also, I just realized I can make this script work for updates, not just the initial installation. That is, if you run it a second time, it will just download and process updates, instead of resetting everything.  I'll start working on that too.

I've finished the revisions to the script.  I've made it much more modular, and it's now easy to expand it for any future merge-mined coins.

It's majorly revised from the last version.  It can now be used to both download for the first time, or to update an existing install.  I put in some logic in there to preserve the RPC username and password for the various coins, too, in case you have other tools that need to use them.

Murdof, if you do adopt this version of the script, you'll have to remove the config files from your download archive (or at least the username and password lines).  The script will add them back in.

Feedback greatly appreciated! This one isn't as thoroughly bug-tested as my last script, but I've squashed all the bugs I was able to find.

Code:
#!/bin/bash

# A function to display help and exit.
Usage()
{
echo "$(basename $0): Downloads and installs bitcoind, p2pool, and other coins for merged mining." >&2
echo "Usage:" >&2
echo "To download precompiled binaries (faster but less secure):" >&2
echo "        $(basename $0) --download" >&2
echo "To download the source code and compile yourself (slower but more secure):" >&2
echo "        $(basename $0) --compile" >&2
echo "You may also choose to download the bitcoin blockchain via http. Add the following to the command line:" >&2
echo "        --http" >&2
echo "If you don't use this, the blockchain will instead download using the (much slower) built-in peer-to-peer process." >&2
echo >&2
exit 1

KyrosKrane this is great stuff!

I haven't updated the guide yet cause I want to try it on a fresh vps in order to see the experience to update the guide.

One other solution is to start a new thread with you taking over since most of the work is yours now and we point people to the new thread so you can update it.

What do you think?

I've been thinking about your proposal for the last day or so. In that time, I've come to realize a few things.

1) Your guide is still necessary. My script is the technical solution, but your guide is the human solution. It does a far better job of explaining what's going on to a relatively new user.

2) The June 21 version of my script, which is basically just glomming all the code from your guide into one script with a little scripting glue, is probably better for you to use. It's clearer to read, and it follows the human-readable guide much more closely.

3) I like to keep adding bells and whistles to my scripts. At some point, that will likely break backwards compatibility (e.g., requiring a new launch command) which would require you to modify your guide. That adds complexity to what should be a simple guide, and it adds to your maintenance overhead to keep the script and the guide in sync.

4) While I'm happy to publish my scripts, they're ultimately written because they're something I use or would likely use. I know I'm not a particularly good representative of the general community, so perhaps I'm not the best candidate to write a guide.

5) I know very little about the practical realities of compiling code on Linux (or any OS, for that matter). I can copy/paste code snippets and compile commands with the best of them, but if you just hand me a git URL and tell me, "go build this," I'd likely be lost.

So, based on all that, my suggestion is that you maintain your guide as the beginner's entry point into p2pool, and use my script from June 21.  Feel free to customize it as you update your guide, or to use the June 23 script if it's better for you. I'll update my June 23 script into a more advanced tool and post a new topic about it in the near future. I've already got some ideas on how to advance it, including having a Web page that essentially generates a custom script for you to download and use.

I finally got around to setting up an Ubuntu machine today. It's downloading the blockchain and hopefully I will get to work on this tomorrow. Looking forward to tinkering.  I have some USBs for testing so go me!

Hi and thanks for a well written guide.

I noticed a couple of things while working through it that had me stuck for a bit as I'm not a linux user and am setting this up in a VM so I can run my own P2Pool node.

In the following I've highlighted what I think are errors in red:

After you install Linux Ubuntu 14.04 LTS, login and execute the following commands:
Code:

wget http://pool.nitro.gr/install-p2pool.sh
sudo sh ./install-p2pool.sh
chmod -R (youruser):(youruser) .*
chmod -R (youruser):(youruser) *

It will install everything (it will use the binaries not compile everything again) and you just have to wait...
Do a reboot and you are done.
Double check with "ls -al" that all files have owner/group your user. If it says root then do "chown -R (user):(group) *" and then "chown -R (user):(group) .*"

Should the chmod be chown as chmod says that format is incorrect?

Should ls -al be ls -la ?

Also I had to do sudo chown -R (user):(group) * & sudo chown -R (user):(group) .* as they were owned by root and wouldn't allow a chown without sudo first.

Sorry if this is wrong, like I said I'm not a unix personal so picking this up as I go.

Without your guide I wouldn't know where to start so thank you once again.

It would be awesome if KyrosKrane's script could be accessed by the wget method you used as that was easy. I'll have to figure out how to get that bash script into the VM and work out how to run it. Having the wget would make unix noobs setup of the P2Pool sooo much easier.

Cheers to both you guys for sharing your work with everyone!
