Installation

Server preparation

apt update && apt upgrade -y
apt install curl iptables build-essential git wget jq make gcc nano tmux htop nvme-cli pkg-config libssl-dev libleveldb-dev tar clang bsdmainutils ncdu unzip libleveldb-dev -y

Install GO

ver="1.20.5"
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

Node installation

git clone https://github.com/lavanet/lava && cd lava
git checkout v4.2.0
make install-all

lavad version --long | grep -e version -e commit
#version: 4.2.0
#commit: 18c395ba01dbd650eac3d276991782faa28270ae

We initialize the node to create the necessary configuration files

lavad init UTSA_guide --chain-id lava-mainnet-1

Download Genesis

wget -O $HOME/.lava/config/genesis.json "https://storage.googleapis.com/lavanet-public-asssets/tge/genesis.json"

sha256sum ~/.lava/config/genesis.json
# 5ba7dc9ac4ee0ea1776c8f13dc45be84ffc2ef3ffbe8271e30b573134ecd61ea

At this stage, we can download the address book

wget -O $HOME/.lava/config/addrbook.json "https://share.utsa.tech/lava/addrbook.json"

Set up node configuration

lavad config chain-id lava-mainnet-1
lavad config keyring-backend os
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.000000001ulava\"/;" ~/.lava/config/app.toml
external_address=$(wget -qO- eth0.me)

sed -i.bak -e "s/^seeds =.*/seeds = \"$seeds\"/" $HOME/.lava/config/config.toml

sed -i \

-e 's/skip_timeout_commit = .*/skip_timeout_commit = false/' \
$HOME/.lava/config/config.toml

(OPTIONAL) Set up pruning

pruning="custom"
pruning_keep_recent="1000"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.lava/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.lava/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.lava/config/app.toml

(OPTIONAL) Set up indexer

indexer="null"
sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.lava/config/config.toml

(OPTIONAL) Enable/Disable Snapshots

snapshot_interval=1000
sed -i.bak -e "s/^snapshot-interval *=.*/snapshot-interval = \"$snapshot_interval\"/" ~/.lava/config/app.toml

Create a service file

tee /etc/systemd/system/lavad.service > /dev/null <<EOF
[Unit]
Description=lavad
After=network-online.target

[Service]
User=$USER
ExecStart=$(which lavad) start
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF
systemctl daemon-reload
systemctl enable lavad
systemctl restart lavad && journalctl -u lavad -f -o cat

If peers do not cling for a long time or you see errors error: wrong Block.Header.AppHash, you need to use State sync or boot from a Snapshot
