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
sudo apt -qy upgrade

Secure Setup

📢

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

Setup ssh for lava user replace YOUR_PUBLIC_SSH_KEY with your own!

sudo adduser lava --disabled-password -q
sudo usermod -aG sudo lava
sudo -u lava 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

Cloning project repository & Compile binaries

cd $HOME
rm -rf lava
git clone https://github.com/lavanet/lava.git
cd lava
git checkout v3.1.0

Export binaries name and build

export LAVA_BINARY=lavad
make build

Latest commit : 8e4f5c433616b2d4324371fa0abff36032e260d8

Prepare binaries for cosmovisor

mkdir -p $HOME/.lava/cosmovisor/genesis/bin
mv build/lavad $HOME/.lava/cosmovisor/genesis/bin/
rm -rf build

Create symlinks

sudo ln -s $HOME/.lava/cosmovisor/genesis $HOME/.lava/cosmovisor/current -f
sudo ln -s $HOME/.lava/cosmovisor/current/bin/lavad /usr/local/bin/lavad -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/lava.service > /dev/null << EOF
[Unit]
Description=lava node service
After=network-online.target
 
[Service]
User=$USER
ExecStart=$(which cosmovisor) run start

[Install]
WantedBy=multi-user.target
EOF

Enable Service

Enable lava systemd service

sudo systemctl daemon-reload
sudo systemctl enable lava

Initialize Node

Setting node configuration

lavad config chain-id lava-testnet-2
lavad config keyring-backend test
lavad config node tcp://localhost:20457

Initialize node

lavad init $MONIKER --chain-id lava-testnet-2

Configure Seeds

Setting up a seed peers

sed -i -e "s|^seeds *=.*|seeds = \"d1d43cc7c7aef715957289fd96a114ecaa7ba756@testnet-seeds.nodex.one:20410\"|" $HOME/.lava/config/config.toml

Pruning Setting

Configure pruning setting

sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \

  -e 's|^pruning-interval *=.*|pruning-interval = "19"|' \
  $HOME/.lava/config/app.toml

Custom Port

Please note that updating the port is optional!

Configure a custom port

sed -i -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:20458\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:20457\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:20460\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:20456\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":20466\"%" $HOME/.lava/config/config.toml
