◼️Andromeda

To install an Andromeda node, follow these steps:

Prerequisites

First, ensure you have the necessary prerequisites installed:

1. Update your system's environment variables by adding the following to your $HOME/.profile[1]:

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export GOBIN=$HOME/go/bin
export PATH=$PATH:/usr/local/go/bin:$GOBIN

1. Source the updated profile:

source $HOME/.profile

Installation

Clone and Build

1. Clone the Andromeda repository[1]:

git clone https://github.com/andromedaprotocol/andromedad.git
cd andromedad
make install

Initialize Configuration

1. Initialize the node configuration[1]:

andromedad init <MONIKER> --chain-id andromeda-1
andromedad config chain-id andromeda-1

Replace <MONIKER> with your chosen node name.

Set Up Keys

1. Create a new key or import an existing wallet[1]:

andromedad keys add <KEY_NAME> --keyring-backend os

To recover an existing wallet:

andromedad keys add <KEY_NAME> --keyring-backend os --recover

Configure Genesis

1. Clone the mainnet repository and copy the genesis file[1]:

git clone https://github.com/andromedaprotocol/mainnet
cd mainnet
cp genesis.json $HOME/.andromeda/config/

Start the Node

1. Start your Andromeda node[1]:

andromedad start

Create Validator (Optional)

1. If you want to create a validator, first obtain some tokens from the Andromeda Faucet, then run[1]:

andromedad tx staking create-validator \
--amount=1000000uandr \
--pubkey=$(andromedad tendermint show-validator) \
--moniker=<MONIKER> \
--chain-id=andromeda-1 \
--commission-rate="0.05" \
--commission-max-rate="0.20" \
--commission-max-change-rate="0.01" \
--min-self-delegation="1" \
--gas="700000" \
--from=<KEY_NAME>

Replace <MONIKER> and <KEY_NAME> with your chosen values.

Set Up Systemd Service (Optional)

1. To run the node as a system service, create a systemd service file[1]:

sudo nano /etc/systemd/system/andromedad.service

1. Insert the following content:

[Unit]
Description=Andromeda Node
After=network-online.target

[Service]
User=root
ExecStart=/root/go/bin/andromedad start
Restart=always
RestartSec=3
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target

1. Enable and start the service:

sudo systemctl enable andromedad.service
sudo systemctl start andromedad.service
