Installation

Updating the System​

apt update && apt upgrade -y

Installing the Necessary Libraries​

apt install make clang pkg-config libssl-dev libclang-dev build-essential git curl ntp jq llvm tmux htop screen gcc lz4 -y < "/dev/null"

Installing Go​

ver="1.21.6"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
rm -rf /usr/local/go
tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm -rf "go$ver.linux-amd64.tar.gz"
echo 'export GOROOT=/usr/local/go' >> $HOME/.bash_profile
echo 'export GOPATH=$HOME/go' >> $HOME/.bash_profile
echo 'export GO111MODULE=on' >> $HOME/.bash_profile
echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
source $HOME/.bash_profile
go version

Setting Variables​

The areas you need to change are written below.

  • $LAVA_NODENAME your validator name
  • $LAVA_WALLET your wallet name
  • If another node is using the port, you can change it below. You must enter a different value where it says 11, again as two digits.
echo "export LAVA_NODENAME=$LAVA_NODENAME"  >> $HOME/.bash_profile
echo "export LAVA_WALLET=$LAVA_WALLET" >> $HOME/.bash_profile
echo "export LAVA_PORT=11" >> $HOME/.bash_profile
echo "export LAVA_CHAIN_ID=lava-testnet-2" >> $HOME/.bash_profile
source $HOME/.bash_profile

Sample​

Let's assume that your Node (LAVA_NODENAME) and Wallet (LAVA_WALLET) name is Anatolian-Guide and the port you will use (LAVA_PORT) will be 16656. The code will be arranged as shown below.

echo "export LAVA_NODENAME=Anatolian-Guide"  >> $HOME/.bash_profile
echo "export LAVA_WALLET=Anatolian-Guide" >> $HOME/.bash_profile
echo "export LAVA_PORT=16" >> $HOME/.bash_profile
echo "export LAVA_CHAIN_ID=lava-testnet-2" >> $HOME/.bash_profile
source $HOME/.bash_profile

Installing Lava​

cd $HOME
git clone https://github.com/lavanet/lava
cd lava
git checkout v1.0.1
install

The version output will be v1.0.1.

Configuring and Launching the Node​

We copy and paste the codes below without making any changes.

lavad config keyring-backend test
lavad config chain-id $LAVA_CHAIN_ID
lavad init --chain-id $LAVA_CHAIN_ID $LAVA_NODENAME

Enabling and Starting the Service​

systemctl daemon-reload
systemctl enable lavad
systemctl start lavad

Checking the Logs​

journalctl -u lavad -f -o cat
warning

AFTER THIS STAGE, WE EXPECT OUR NODE TO SYNC.

Checking Synchronization​

Unless we get a false output, we do not move on to the next step, namely creating a validator.

lavad status 2>&1 | jq .SyncInfo

Wallet​

Creating a New Wallet​

We do not change the $LAVA_WALLET section, we named our wallet with variables at the beginning of the installation.

lavad keys add $LAVA_WALLET

Importing an Existing Wallet​

lavad keys add $LAVA_WALLET --recover

Wallet and Valoper Info​

Here we add our wallet and valve information to the variable.

LAVA_WALLET_ADDRESS=$(lavad keys show $LAVA_WALLET -a)
LAVA_VALOPER_ADDRESS=$(lavad keys show $LAVA_WALLET --bech val -a)
echo 'export LAVA_WALLET_ADDRESS='${LAVA_WALLET_ADDRESS} >> $HOME/.bash_profile
echo 'export LAVA_VALOPER_ADDRESS='${LAVA_VALOPER_ADDRESS} >> $HOME/.bash_profile
source $HOME/.bash_profile

Faucet​

Request tokens by sending a message to the #🚰┃faucet channel on the Discord server as follows.

$request Lava-Address

Checking Wallet Balance​

lavad query bank balances $LAVA_WALLET_ADDRESS
warning

If the synchronization is completed, we proceed to the following step.

Creating Validator​

You do not need to make any changes to the following command other than the places specified below;

  • identity where it says XXXX1111XXXX1111 you write your identification number given to you as a member of the keybase site.
  • details You can write information about yourself where it says Always forward with the Anatolian Team 🚀.
  • website where it says https://anatolianteam.com, if you have a website or twitter etc. You can write your address.
  • security-contact Your email address.
