Hardware requirements: RAM: 64 GB RAM Storage: 2 TB NVME SSD OS: Linux 22.04 Rent a server here (optional): https://www.interserver.net/r/950716

Set Node name

Change it to anything you like.

MONIKER="my_node"

Install dependencies

sudo apt -q update
sudo apt -qy install curl git jq lz4 build-essential
sudo apt -qy upgrade

Install GO

This will install Go version 1.22.8

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.22.8.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)

go version

Download and build binaries

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

# Build binaries
export LAVA_BINARY=lavad
make build

# Prepare binaries for Cosmovisor
mkdir -p $HOME/.lava/cosmovisor/genesis/bin

Set Ports

This is a more simplified command to manually set the Ports of your LavaNet node. You can manually change it depending on your needs. Make sure there are no conflicts as this might cause the node to not run.

CUSTOM_PORT=144

sed -i -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${CUSTOM_PORT}58\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://0.0.0.0:${CUSTOM_PORT}57\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:${CUSTOM_PORT}60\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:${CUSTOM_PORT}56\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":${CUSTOM_PORT}66\"%" $HOME/.evmosd/config/config.toml
sed -i -e "s%^address = \"tcp://localhost:1317\"%address = \"tcp://0.0.0.0:${CUSTOM_PORT}17\"%; s%^address = \":8080\"%address = \":${CUSTOM_PORT}80\"%; s%^address = \"localhost:9090\"%address = \"0.0.0.0:${CUSTOM_PORT}90\"%; s%^address = \"localhost:9091\"%address = \"0.0.0.0:${CUSTOM_PORT}91\"%; s%^address = \"127.0.0.1:8545\"%address = \"0.0.0.0:${CUSTOM_PORT}45\"%; s%^ws-address = \"127.0.0.1:8546\"%ws-address = \"0.0.0.0:${CUSTOM_PORT}46\"%" $HOME/.evmosd/config/app.toml

Download latest chain snapshot

curl -L https://snapshots.kjnodes.com/lava/snapshot_latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.lava
[[ -f $HOME/.lava/data/upgrade-info.json ]] && cp $HOME/.lava/data/upgrade-info.json $HOME/.lava/cosmovisor/genesis/upgrade-info.json

Make sure that the port numbers you will assign is not in use.

Use this command to check.

netstat -na | grep [port-number]

Replace port-number depending on what port you are trying to check.

• Tendermint RPC

Navigate to /.lava/config and open config.toml file. Take note of the URL and Port.

• Rest (API)

Navigate to /.lava/config and open app.toml file. Take note of the URL and Port. Make sure it is set to enable = true.

• gRPC

Navigate to /.lava/config and open app.toml file. Take note of the URL and Port. Make sure both gRPC and gRPC-web is set to enable = true.

Setup Firewall

These are just recommended port settings, which I am currently using. Change it depending on your own server settings.

sudo ufw default deny incoming
sudo ufw default allow outgoing

#ssh port
sudo ufw allow 22

#webmin port
sudo ufw allow 10000

#Allowed Ports
sudo ufw allow 14456/tcp
sudo ufw allow 14457/tcp
sudo ufw allow 14460/tcp
sudo ufw allow 14490/tcp
sudo ufw allow 14417/tcp
sudo ufw allow 26666/tcp
sudo ufw allow 26667/tcp
sudo ufw allow 26670/tcp
sudo ufw allow 2224
sudo ufw allow 443
sudo ufw allow 80

sudo ufw enable

Start service and check the logs

sudo systemctl start lava.service && sudo journalctl -u lava.service -f --no-hostname -o cat

Check sync status

Run the following command:

lavad status 2>&1 | jq .SyncInfo

If you get a result false that means node is fully synced.

Check connected peers:

sudo netstat -anp | grep ESTABLISHED | grep lavad | grep -v \"127.0.0.1\

Archive Snapshot

If you want to run a full archive node, you can use this snapshot. The following commands will delete the existing /data folder. Make sure you create a backup in case you need it. Set the proper pruning settings to nothing before running the node.

sudo systemctl stop lava.service
cp $HOME/.lava/data/priv_validator_state.json $HOME/.lava/priv_validator_state.json.backup
rm -rf $HOME/.lava/data
curl -L https://storage.mellifera.network/lava_mainnet/archive_1463986.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.lava
mv $HOME/.lava/priv_validator_state.json.backup $HOME/.lava/data/priv_validator_state.json

Start the node and let it sync

sudo systemctl start lava.service && sudo journalctl -u lava.service -f --no-hostname -o cat
