ANOTHER STEEM WITNESS SETUP GUIDE?!

Yeah, well, believe it or not the currently available material is a bit lacking or outdated. Crypto changes quickly and the guides representing the tech should as well. Understandably, though, it is hard to keep up with these constant changes. Thus....

I PRESENT THE CONCISE STEEM WITNESS SETUP GUIDE

Disclaimer:

I spent a lot of time and effort writing and compiling this guide in such a way that you can essentially just start from the top at Update and upgrade packages and copy/paste every following command in order to get a fully working Witness server. However, despite the ease of implementation this guide provides, I HIGHLY encourage you to become familiar with the technology and exactly what this guide is having you do. The headings should help you to understand the goal of what each block of commands is going to achieve.

Let's go ahead and assume you know what a witness is and why you would want to manage one. This will save us some time and space in this guide. For the sake of sanity, let us assume one more thing. That is that you know where you are going to obtain a server(s) with the necessary hardware requirements.

Server Hardware Specifications

• RAM: 8GB Minimum - 16GB+ Preferred
• Storage: 50GB+
• Network: 1Gb/s+ Preferred
• OS: Ubuntu 16.04-16.10

Links

• STEEM repo
  • Open source repo containing precompiled source code for Steemd and the cli_wallet
• @GTG Blockchain Snapshot
  • ~17GB snapshot file used to replay the blockchain thru Steemd on first run
• @Netuoso Generic Witness Config
  • Line 8: Shared memory size.
    • df -h
    • look for /dev/shm or /shm and the free space remaining
    • set shared-file-size just below the limit
  • Line 9: Shared file dir.
    • use the result from df -h (eg: /dev/shm)
  • Line 75: Witness
    • set this to your STEEM username the Witness will use
  • Line 84: Private key
    • this key will be generated via the cli_wallet with command suggest_brain_key
  • Line 107: Log level
    • you can change this to warn if you want less output ..
• @Someguy123 steemfeed-js
• Steemd Systemd Script
• Cli_wallet Systemd Script
• Price Feed Systemd Script

Update and upgrade packages

It is always good to try to keep updated and patched software installed on your server. These commands will help you with that:

• sudo apt-get update -y
• sudo apt-get upgrade -y

Install dependencies

We will need to compile C source code. These commands will help you install the dependencies that will be required:

• sudo apt-get install git cmake g++ python-dev autotools-dev libicu-dev build-essential libbz2-dev libboost-all-dev libssl-dev libncurses5-dev doxygen libreadline-dev dh-autoreconf htop

Compile Steemd and cli_wallet

In order to communicate with the blockchain and configure our witness/wallet we will need to compile from source. These commands will help you through the process:

• cd $HOME
• git clone https://github.com/steemit/steem
• cd steem
• git submodule update --init --recursive
• cmake -DCMAKE_BUILD_TYPE=Release -DENABLE_CONTENT_PATCHING=OFF -DLOW_MEMORY_NODE=ON
• make steemd cli_wallet
• sudo cp programs/*/{steemd,cli_wallet} /usr/local/bin

Run Steemd for the first time to generate the data_dir

• cd $HOME
• steemd
• wait 5 seconds then exit (CTRL+C)
• curl https://raw.githubusercontent.com/netuoso/cryptoscripts/master/steemit-config.ini.witness > witness_node_data_dir/config.ini

Generate a brain_wallet_key

• screen (press enter)
• cd $HOME (in case you aren't already there)
• steemd
• CTRL+A then CTRL+C (create new screen window)
• cli_wallet
• set_password SOMESECRETPASSWORDYOUWILLREMEMBER
• unlock SOMESECRETPASSWORDYOUWILLREMEMBER
• suggest_brain_key
• copy/paste the entire result into a note window so you won't lose it (I use lastpass secure notes)
• CTRL+D (exit the wallet)
• CTRL+D (exit the second screen window)
• CTRL+C (exit Steemd process)

Customize the config

• NOTE: (see Links section for more information about each line)
• nano $HOME/witness_node_data_dir/config.ini
• edit line 8 with your shared-file-size
• edit line 9 with your shared-file-dir
• edit line 75 with your witness account name
• edit line 84 with your private key from the step above (should be in the note)
• edit line 107 with desired log level (info/warn) [optional]

Download the blockchain snapshot

• cd $HOME
• wget https://gtg.steem.house/get/blockchain/block_log -o witness_node_data_dir/blockchain/block_log

Replay the blockchain (this is a good chance to see if anything went wrong)

• steemd --replay (this can take hours)
• you should now be seeing some information about the replay
• a way to check this step is working...
  • open a new terminal window (hopefully you are still in screen CTRL+A then CTRL+C)
  • ls -al $HOME/witness_node_data_dir/blockchain (the block_log.index will grow to ~100MB)
  • ls -al $HOME/witness_node_data_dir/blockchain (did block_log.index change size? its still indexing.. be patient)
• ignore red text saying warnings or applying hard fork .. these are expected
• the replay is finished after 100% and when you see handling block
• exit when the replay is finished (CTRL+C)

Set up steemfeed-js (or find another price feed)

• cd $HOME
• curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
• sudo apt-get install nodejs -y
• git clone https://github.com/Someguy123/steemfeed-js
• cd steemfeed-js
• mv config.example.json config.json
• nano config.json (add your STEEM username and active private key)
• npm install

Install the Systemd service scripts and enable on boot

• cd $HOME
• curl https://raw.githubusercontent.com/netuoso/cryptoscripts/master/steemd.service > steemd.service
• curl https://raw.githubusercontent.com/netuoso/cryptoscripts/master/cli_wallet.service > cli_wallet.service
• curl https://raw.githubusercontent.com/netuoso/cryptoscripts/master/price_feed.service > price_feed.service
• sudo chown root:root *service
• sudo chmod 0644 *service
• sudo mv *service /etc/systemd/system/
• sudo systemctl daemon-reload
• sudo systemctl enable steemd
• sudo systemctl enable cli_wallet
• sudo systemctl enable price_feed

Restart Steemd; import STEEM active private key; broadcast Witness

• cd $HOME
• sudo service steemd restart
• cli_wallet
• unlock SOMESECRETPASSWORDYOUWILLREMEMBER
• import_key ACTIVEPRIVATEKEYFROMSTEEM
• update_witness "YOUR_WITNESS_NAME_HERE" "https://link_to_your_witness_intent_post" "ACTIVEPUBLICKEYFROMSTEEM" {"account_creation_fee":"0.200 STEEM","maximum_block_size":131072,"sbd_interest_rate":0} true
• CTRL+C (exit wallet)

Enable cli_wallet and price_feed

• sudo service cli_wallet restart
• sudo service price_feed restart

Setup alias to view Steemd logs

• nano $HOME/.bashrc
• add the following:
• alias steemdlogs='sudo journalctl -u steemd.service -f'
• alias feedlogs='sudo journalctl -u price_feed.service -f'
• now you can use steemdlogs and feedlogs to view the logs for either service
• you need to logout/login or open a new shell for the alias to become active

Congratulations. You are now a STEEM Witness. Make sure you campaign and stay active! Go get those votes!

How to change your Witness SBD interest or account creation fee (SBD 2% interest example)

• cd $HOME
• cli_wallet
• unlock SOMESECRETPASSWORDYOUWILLREMEMBER
• update_witness "YOUR_WITNESS_NAME_HERE_AGAIN" "https://link_to_your_witness_update_post" "ACTIVEPUBLICKEYFROMSTEEM" {"account_creation_fee":"0.200 STEEM","maximum_block_size":131072,"sbd_interest_rate":200} true
