7. Configure Node

Update app.toml ports

sed -i.bak -e "s%:1317%:${LAVA_PORT}317%g;
s%:8080%:${LAVA_PORT}080%g;
s%:9090%:${LAVA_PORT}090%g;
s%:9091%:${LAVA_PORT}091%g;
s%:8545%:${LAVA_PORT}545%g;
s%:8546%:${LAVA_PORT}546%g;
s%:6065%:${LAVA_PORT}065%g" $HOME/.lava/config/app.toml

Update config.toml ports

sed -i.bak -e "s%:26658%:${LAVA_PORT}658%g;
s%:26657%:${LAVA_PORT}657%g;
s%:6060%:${LAVA_PORT}060%g;
s%:26656%:${LAVA_PORT}656%g;
s%^external_address = \"\"%external_address = \"$(wget -qO- eth0.me):${LAVA_PORT}656\"%;
s%:26660%:${LAVA_PORT}660%g" $HOME/.lava/config/config.toml

Configure Pruning

Pruning Strategy

Select a strategy to manage your node's storage usage.

💡Recommended for Validators to fine-tune storage.

Keep Recent

Number of recent blocks/states to keep in disk.

blocks

Interval

Frequency of deletion. E.g., 10 means prune every 10 blocks.

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

8. Create Services

sudo tee /etc/systemd/system/lavad.service > /dev/null <<EOF
[Unit]
Description=Lava node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.lava
ExecStart=$(which lavad) start --home $HOME/.lava
Restart=on-failure
RestartSec=5
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

9. Start Services

sudo systemctl daemon-reload
sudo systemctl enable lavad
sudo systemctl restart lavad && sudo journalctl -u lavad -fo cat
