Manual Installation

Let's explore the manual installation process as we set up a node with Cosmovisor!

Install Dependencies

Update system package and install build tools
sudo apt -q update
sudo apt -qy install curl git jq lz4 build-essential fail2ban ufw unzip
sudo apt -qy upgrade

Secure Setup

πŸ“’

This step is optional, and you can choose to skip ahead to configure moniker.

Setup ssh for mantra user replace YOUR_PUBLIC_SSH_KEY with your own!
sudo adduser mantra --disabled-password -q
sudo usermod -aG sudo mantra
sudo -u mantra bash -c 'mkdir -p ~/.ssh && echo "YOUR_PUBLIC_SSH_KEY" >> ~/.ssh/authorized_keys && chmod 700 ~/.ssh && chmod 600 ~/.ssh/authorized_keys'

Configure Moniker

Replace <your-moniker-name> with your own validator name
MONIKER="<your-moniker-name>"

Install Go

install go version 1.20.10
sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.20.10.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local
eval $(echo 'export PATH=$PATH:/usr/local/go/bin' | sudo tee /etc/profile.d/golang.sh)
eval $(echo 'export PATH=$PATH:$HOME/go/bin' | tee -a $HOME/.profile)

Build Binaries

Note: mantrachain binaries needs libwasmvm.x86_64.so installed on your systemd to run the binaries

Download libwasmvm.x86_64.so file
sudo wget -O /usr/lib/libwasmvm.x86_64.so https://github.com/CosmWasm/wasmvm/releases/download/v1.3.0/libwasmvm.x86_64.so
Download mantrachain binaries
cd $HOME
wget https://snap.nodex.one/mantra-testnet/mantrachaind-linux-amd64.zip
unzip mantrachaind-linux-amd64.zip
chmod +x mantrachaind

Prepare binaries for cosmovisor
mkdir -p $HOME/.mantrachain/cosmovisor/genesis/bin
mv mantrachaind $HOME/.mantrachain/cosmovisor/genesis/bin/
Create symlinks
sudo ln -s $HOME/.mantrachain/cosmovisor/genesis $HOME/.mantrachain/cosmovisor/current -f
sudo ln -s $HOME/.mantrachain/cosmovisor/current/bin/mantrachaind /usr/local/bin/mantrachaind -f

Cosmovisor Setup

Install cosmovisor
go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@v1.5.0

Create Service

Create a systemd service
sudo tee /etc/systemd/system/mantra.service > /dev/null << EOF

Enable Service

Enable mantra systemd service
sudo systemctl daemon-reload
sudo systemctl enable mantra

Initialize Node

Setting node configuration
mantrachaind config chain-id mantrachain-testnet-1
mantrachaind config keyring-backend test
mantrachaind config node tcp://localhost:22257
Initialize node
mantrachaind init $MONIKER --chain-id mantrachain-testnet-1
