Here's more detailed miner setup for Ubuntu 15.10 and 16.04

Here's more detailed miner setup for Ubuntu 15.10 and 16.04 (If you want to use previous versions, you should compile boost). Ubuntu server version is recommended.

Setup Your Miner

• Start up your machine

sudo apt-get update
#Enter password
sudo apt-get install screen autoconf autotools-dev build-essential cmake g++ git libboost-all-dev libboost-dev libbz2-dev libdb++-dev libdb-dev libicu-dev libreadline-dev libssl-dev libtool openssl python-dev uuid-dev ncurses-dev doxygen qt5-default
git clone https://github.com/steemit/steem
cd steem
git submodule update --init --recursive
cmake -DENABLE_CONTENT_PATCHING=OFF .
make

• Wait for compiling done

sudo cp ./programs/steemd/steemd /usr/bin/
sudo cp ./programs/cli_wallet/cli_wallet /usr/bin/
cd ~/
steemd

• After 30 seconds Ctrl+C to exit steemd

nano ./witness_node_data_dir/config.ini

• Copy the below lines and paste at the top of config.ini

seed-node = 212.117.213.163:2016
seen-node = 185.82.203.92:2001
seed-node = 104.236.82.250:2001
seed-node = 104.199.157.70:2001
seed-node = steem.kushed.com:2001
seed-node = steemd.pharesim.me:2001
seed-node = seed.steemnodes.com:2001
seed-node = steemseed.dele-puppy.com:2001
seed-node = seed.steemwitness.com:2001
rpc-endpoint = 127.0.0.1:8090

• Now you're ready to mine. Use your private key that starts with 5, or get it from http://offlinebitcoins.com
• Let's start the miner in new screen named steemd

screen -dmS steemd steemd --miner='["YourWantedID","5YourPrivatekey"]' --witness='"YourWantedID"' --mining-threads=4    (if you have 32 core, change it from 4 to 32)

• When you're get involved in the miner queue, your account will be created and your hash will go down to near zero

Multiple Miners

• If you want to have multiple miner, you can set different data directory

steemd -d ~/newdatadir --miner='["YourWantedID","5YourPrivatekey"]' --witness='"YourWantedID"' --mining-threads=4
nano ~/newdatadir/config.ini

• Copy and paste the below

seed-node = 212.117.213.163:2016
seen-node = 185.82.203.92:2001
seed-node = 104.236.82.250:2001
seed-node = 104.199.157.70:2001
seed-node = steem.kushed.com:2001
seed-node = steemd.pharesim.me:2001
seed-node = seed.steemnodes.com:2001
seed-node = steemseed.dele-puppy.com:2001
seed-node = seed.steemwitness.com:2001

Cli_wallet commands

• To use cliwallet, you must setup password first

set_password WalletPassword
unlock WalletPassword

• Import your account

import_key 5YourPrivateKey

• Check your balance

list_my_accounts

• Transfer

transfer "SenderID" "ReceiverID" "000.000 STEEM" "memo" true   (Make sure that the amount have at least three digits, maybe a bug?)

Good luck with your mining :)
