Installing Required Packages and Go

sudo apt update && sudo apt upgrade -y
sudo apt install curl tar wget clang pkg-config libssl-dev jq build-essential bsdmainutils git make ncdu -y

Download and install Go:

cd $HOME
ver="1.21.3"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

Setup Humans Node

git clone https://github.com/humansdotai/humans.git
cd humans
git checkout v1.0.0
make install

Initialize the node with your moniker:

humansd init $MONIKER --chain-id humans_1089-1

Configure seeds, gas prices, and further settings for optimal performance:

sed -i -e "s|^seeds *=.*|seeds = \"[e-mail]:17656,[e-mail]:18456,0e959a22dfdd34ac16f9af82d76ec6ae5f0e8e73@135.181.75.235:10256,[e-mail]:12259\"|" $HOME/.humansd/config/config.toml

Load the latest snapshot to sync your node quickly from the websites below:

Install and Configure Systemd

echo "[Unit]
Description=Humans
After=network.target

[Service]
User=$USER
Type=simple
ExecStart=$(which humansd) start --home /path/.humansd/ --chain-id humans_1089-1 --metrics --evm.tracer=json --minimum-gas-prices=1800000000aheart json-rpc.api eth,txpool,personal,net,debug,web3,miner --api.enable
Restart=on-failure
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target" > $HOME/humansd.service

sudo mv $HOME/humansd.service /etc/systemd/system

sudo systemctl enable humansd
sudo systemctl restart humansd 

Monitor your node

sudo journalctl -u humansd -f --no-hostname -o cat

Check and Configure Ports

• nano $HOME/.humansd/config/app.toml
  [json-rpc]
  address = "127.0.0.1:8545"
  ws-address = "127.0.0.1:8546"
  
  [api]
  enable = true
  swagger = false
  address = "tcp://0.0.0.0:1317"
  
  nano $HOME/.humansd/config/config.toml
  [rpc]
  laddr = "tcp://127.0.0.1:26657"

Use Caddy for Domain Binding

sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install caddy

Configure Caddyfile for domain routing:

nano /etc/caddy/Caddyfile

:80 {
    root * /usr/share/caddy
    file_server
}

rpc-humans.huginn.tech {
    reverse_proxy http://127.0.0.1:26657 {
        header_down Access-Control-Allow-Origin *
    }
}

api.humans.huginn.tech {
    reverse_proxy http://127.0.0.1:1317 {
        header_down Access-Control-Allow-Origin *
    }
}

evm-rpc.humans.huginn.tech {
    reverse_proxy http://127.0.0.1:8545 {
        header_down Access-Control-Allow-Origin *
    }
}
