** Add repository and install bitcoind ** 

sudo apt-get install build-essential
sudo apt-get install libtool autotools-dev autoconf
sudo apt-get install libssl-dev
sudo apt-get install libboost-all-dev
sudo add-apt-repository ppa:luke-jr/bitcoincore
sudo apt-get update
sudo apt-get install bitcoind
mkdir ~/.bitcoin/ && cd ~/.bitcoin/
nano bitcoin.conf

** Add config to bitcoin.conf file ** 

use https://jlopp.github.io/bitcoin-core-config-generator/

example:

# Generated by https://jlopp.github.io/bitcoin-core-config-generator/

# This config should be placed in following path:
# ~/.bitcoin/bitcoin.conf

# [debug]
# Enable debug logging
debug=rpc
# Log IP Addresses in debug output.
logips=1
# Reduce the log file size on restarts
shrinkdebuglog=1
# Run this node on the Bitcoin Test Network. Equivalent to -chain=test
# testnet=1

# [rpc]
# Accept command line and JSON-RPC commands.
server=1
# Allow JSON-RPC connections from specified source. Valid for <ip> are a single IP (e.g. 1.2.3.4), a network/netmask
# (e.g. 1.2.3.4/255.255.255.0) or a network/CIDR (e.g. 1.2.3.4/24). This option can be specified multiple times.
rpcallowip=127.0.0.1

# [wallet]
# Bech32
addresstype=bech32
# Bech32
changetype=bech32

# [core]
# Specify a non-default location to store blockchain data.
# blocksdir=/mnt/.../

# Options only for mainnet 
[main]
# Bind to given address to listen for JSON-RPC connections.
rpcbind=0.0.0.0
# Listen for JSON-RPC connections on this port
rpcport=8332

# Options only for testnet 
[test]
# Bind to given address to listen for JSON-RPC connections.
rpcbind=0.0.0.0
# Listen for JSON-RPC connections on this port
rpcport=18332

** Start bitcoind ** 

bitcoind --daemon

** To make changes to bitcoin.conf, first stop bitcoind: ** 

bitcoin-cli stop

** Test bitcoind is running and working **

bitcoin-cli getblockchaininfo

** While waiting for `initialblockdownload`, install Rust  **

sudo apt install clang cmake
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup toolchain install nightly --allow-downgrade
rustup default nightly

** Install and start Electrs after `initialblockdownload` is false from `bitcoin-cli getblockchaininfo` ** 

git clone https://github.com/blockstream/electrs #blockstream fork of electrs
cd electrs
git checkout new-index
ulimit -n 65535
#TESTNET (from electrs folder)

cargo run --release --bin electrs -- --help

**electrs setup can during setup and will take >48 hrs days to fully index mainnet Bitcoin, be prepared to restart multiple times**
