Lava

Run the node

Recommended Hardware Requirements

🖼️ Provider

Before start install Lava provider, you must ensure you have:

• Your own domain (If yet buy one: namecheap
• Lava node running
• Lavap binaries installed

Step 1: Setup A record for your domain

Go to DNS setting:

• Create A record: Host = LAVA; Value = Your server public IP.

Step 2: Install Required Dependencies

sudo apt update
sudo apt install certbot net-tools nginx python3-certbot-nginx -y

Step 3: Generate Certificate

sudo certbot certonly -d yourdomain.com -d LAVA.yourdomain.com

Select 1 for Nginx Web Server Plugin

Enter your valid email

Step 4: Validate Certificate

sudo certbot certificates

Step 5: Create Nginx server

cd /etc/nginx/sites-available/

sudo nano lava_server

Copy & Paste

server {
    listen 443 ssl http2;
    server_name lava.your-domain.com;

    ssl_certificate /etc/letsencrypt/live/your-domain.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/your-domain.com/privkey.pem;
    error_log /var/log/nginx/debug.log debug;

    location / {
        proxy_pass http://127.0.0.1:2224;
        grpc_pass 127.0.0.1:2224;
    }
}

Step 6: Create a link

sudo ln -s /etc/nginx/sites-available/lava_server /etc/nginx/sites-enabled/lava_server

Step 7: Test Nginx Configuration

sudo nginx -t

Expected result

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Step 8: Run Nginx

sudo systemctl restart nginx

Step 9: Create Docker file

cd ~/lava/config
nano lava-provider.yml

Copy & Paste

endpoints:
    - api-interface: tendermintrpc
      chain-id: LAV1
      network-address:
        address: 127.0.0.1:2224
        disable-tls: true
      node-urls:
        - url: ws://127.0.0.1:26657/websocket
        - url: http://127.0.0.1:26657
    - api-interface: grpc
      chain-id: LAV1
      network-address:
        address: 127.0.0.1:2224
        disable-tls: true
      node-urls: 
        url: 127.0.0.1:9090
    - api-interface: rest
      chain-id: LAV1
      network-address:
        address: 127.0.0.1:2224
        disable-tls: true
      node-urls: 
        url: http://127.0.0.1:1317

Step 10: Create reward storage

mkdir /root/.lava/config/reward/ 

Step 10: Run Docker

screen -S lava-provider

lavap rpcprovider lava-provider.yml --from Adam_VNBnode  --geolocation 1 --chain-id lava-testnet-2 --reward-server-storage /root/.lava/config/reward/ --log_level debug

Expected result

Step 11: Test RPC provider

lavap test rpcprovider --from $MONIKER  --endpoints "lava.your-domain.com:443,LAV1"

Expected result

Step 12: Stake the Provider on Chain

Make sure your wallet have enough token lava

lavap tx pairing stake-provider LAV1 "50000000000ulava" "lava.your-domain.com:443,1" 1 --from $MONIKER --provider-moniker $MONIKER --keyring-backend "test" --chain-id "lava-testnet-2" --gas="auto" --gas-adjustment "1.5" --gas "auto" --gas-prices "0.0001ulava"

Step 13: Test RPC provider again

lavap test rpcprovider --from $MONIKER  --endpoints "lava.your-domain.com:443,LAV1"

Step 14: Check the status of RPC provider

https://info.lavanet.xyz/provider/ Enter your wallet address & Enjoy

🖼️ Validator

1.Set Validator nam

MONIKER="Your-name_VNBnode"

2.Update system

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

3. Install Go version 1.20.5

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.20.5.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 $HOME/.profile)
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

4. Install GCC

sudo apt install build-essential

5. Install all Binaries 🛠️

git clone https://github.com/lavanet/lava.git
cd lava
make install-all

Check version

lavad version && lavap version

6.Build all Binaries

make build-all

7. Set up a local node

Download app configurations

• Download setup configuration Download the configuration files needed for the installation

# Download the installation setup configuration
git clone https://github.com/lavanet/lava-config.git
cd lava-config/testnet-2

# Read the configuration from the file
# Note: you can take a look at the config file and verify configurations
source setup_config/setup_config.sh

• Set app configurations Copy lavad default config files to config Lava config folder

echo "Lava config file path: $lava_config_folder"
mkdir -p $lavad_home_folder
mkdir -p $lava_config_folder
cp default_lavad_config_files/* $lava_config_folder

Set the genesis file

• Set the genesis file in the configuration folder

# Copy the genesis.json file to the Lava config folder
cp genesis_json/genesis.json $lava_config_folder/genesis.json

Set up Cosmovisor

• Set up cosmovisor to ensure any future upgrades happen flawlessly. To install Cosmovisor:

go install github.com/cosmos/cosmos-sdk/cosmovisor/cmd/[email protected]

# Create the Cosmovisor folder and copy config files to it
mkdir -p $lavad_home_folder/cosmovisor/genesis/bin/

# Download the genesis binary
wget -O  $lavad_home_folder/cosmovisor/genesis/bin/lavad "https://github.com/lavanet/lava/releases/download/v0.21.1.2/lavad-v0.21.1.2-linux-amd64"
chmod +x $lavad_home_folder/cosmovisor/genesis/bin/lavad

# Set the environment variables
echo "# Setup Cosmovisor" >> ~/.profile
echo "export DAEMON_NAME=lavad" >> ~/.profile
echo "export CHAIN_ID=lava-testnet-2" >> ~/.profile
echo "export DAEMON_HOME=$HOME/.lava" >> ~/.profile
echo "export DAEMON_ALLOW_DOWNLOAD_BINARIES=true" >> ~/.profile
echo "export DAEMON_LOG_BUFFER_SIZE=512" >> ~/.profile
echo "export DAEMON_RESTART_AFTER_UPGRADE=true" >> ~/.profile
echo "export UNSAFE_SKIP_BACKUP=true" >> ~/.profile
source ~/.profile

Initialize the chain

$lavad_home_folder/cosmovisor/genesis/bin/lavad init \
my-node \
--chain-id lava-testnet-2 \
--home $lavad_home_folder \
--overwrite
cp genesis_json/genesis.json $lava_config_folder/genesis.json

Check version

cosmovisor version

Create Cosmovisor unit file

echo "[Unit]
Description=Cosmovisor daemon
After=network-online.target
[Service]
Environment="DAEMON_NAME=lavad"
Environment="DAEMON_HOME=${HOME}/.lava"
Environment="DAEMON_RESTART_AFTER_UPGRADE=true"
Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=true"
Environment="DAEMON_LOG_BUFFER_SIZE=512"
Environment="UNSAFE_SKIP_BACKUP=true"
User=$USER
ExecStart=${HOME}/go/bin/cosmovisor start --home=$lavad_home_folder --p2p.seeds $seed_node
Restart=always
RestartSec=3
LimitNOFILE=infinity
LimitNPROC=infinity
[Install]
WantedBy=multi-user.target
" >cosmovisor.service
sudo mv cosmovisor.service /lib/systemd/system/cosmovisor.service

Enable and start the Cosmovisor service

# Enable the cosmovisor service so that it will start automatically when the system boots
sudo systemctl daemon-reload
sudo systemctl enable cosmovisor.service
sudo systemctl restart systemd-journald
sudo systemctl start cosmovisor

Verify cosmovisor setup

• Check the status of the service

sudo systemctl status cosmovisor

• To view the service logs - to escape, hit CTRL+C

sudo journalctl -u cosmovisor -f

Verify node status

# Check if the node is currently in the process of catching up
$HOME/.lava/cosmovisor/current/bin/lavad status | jq .SyncInfo.catching_up

Ensure your node synched & Wait until you see the output: "false"

8. Create wallet

current_lavad_binary="$HOME/.lava/cosmovisor/current/bin/lavad"
ACCOUNT_NAME=$MONIKER
$current_lavad_binary keys add $ACCOUNT_NAME

Ensure you write down the mnemonic as you can not recover the wallet without it

List the key & Wallet

$current_lavad_binary keys list

obtain your validator pubkey

$current_lavad_binary tendermint show-validator

Check balance of your account

YOUR_ADDRESS=$($current_lavad_binary keys show -a $ACCOUNT_NAME)
$current_lavad_binary query \
    bank balances \
    $YOUR_ADDRESS \
    --denom ulava

9. Stake as validator

$current_lavad_binary tx staking create-validator \
    --amount="10000ulava" \
    --pubkey=$($current_lavad_binary tendermint show-validator --home "$HOME/.lava/") \
    --moniker="Your-name_VNBnode" \
    --chain-id=lava-testnet-2 \
    --commission-rate="0.10" \
    --commission-max-rate="0.20" \
    --commission-max-change-rate="0.01" \
    --min-self-delegation="10000" \
    --gas="auto" \
    --gas-adjustment "1.5" \
    --gas-prices="0.05ulava" \
    --home="$HOME/.lava/" \
    --from=$ACCOUNT_NAME
