Fullnode Installation Guide

Chain ID: mayachain-mainnet-v1 | Current Node Version: v1.108.0

Install Go and other requirements

Install Go

We will use Go v1.20.0 as an example here. The code below also cleanly removes any previous Go installation.

sudo rm -rvf /usr/local/go/
wget https://golang.org/dl/go1.20.12.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.20.12.linux-amd64.tar.gz
rm go1.20.0.linux-amd64.tar.gz

Configure Go

Unless you want to configure in a non-standard way, then set these in the ~/.bash_profile for bash and ~/.zshrc for zsh.

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

Install protobuf-compiler

apt-get update
apt-get install -y git make protobuf-compiler

Install docker and docker compose plugin

https://docs.docker.com/engine/install/

Install Node

Install the current version of node binary.

*You can see tags in mayanode's repo tags

git clone https://gitlab.com/mayachain/mayanode
cd mayanode
git checkout <latest version tag>
make openapi protob

Install binary

TAG=mainnet NET=mainnet make install

Run Node

MAYA_COSMOS_TELEMETRY_ENABLED=true CHAIN_ID=mayachain-mainnet-v1 NET=mainnet SEEDS=15.156.45.237,18.217.85.10 bash ./build/scripts/fullnode.sh

Create Service File

Create a mayanode.service file in the /etc/systemd/system folder with the following code snippet. Make sure to replace USER with your Linux username. You need sudo privilege to do this step.

[Install]

Download Snapshot

Please use a snapshot in order to avoid syncing from start. You will need to install aws-cli

mkdir -p ~/.mayanode/data
aws s3 cp --recursive s3://public-snapshots-mayanode/full/<snapshot height> ~/.mayanode/data

Start Node Service

# Enable service
sudo systemctl enable mayanode.service

# Start service
sudo systemctl start mayanode

# Check logs
sudo journalctl -feu mayanode

Other Considerations

This installation guide is the bare minimum to get a node started. You should consider the following as you become a more experienced node operator.

• Configure firewall to close most ports while only leaving the p2p port (typically 27146) open

• Use custom ports for each node so you can run multiple nodes on the same server
