#### ***Set custom ports***

You can change value CUSTOM\_PORT=168 To any other ports

```bash
CUSTOM_PORT=168
```

```bash
sed -i -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${CUSTOM_PORT}58\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:${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\"%" $HOME/.lava/config/config.toml
sed -i -e "s%^address = \"tcp://localhost:1317\"%address = \"tcp://localhost:${CUSTOM_PORT}17\"%; s%^address = \":8080\"%address = \":${CUSTOM_PORT}80\"%; s%^address = \"localhost:9090\"%address = \"localhost:${CUSTOM_PORT}90\"%; s%^address = \"localhost:9091\"%address = \"localhost:${CUSTOM_PORT}91\"%; s%^address = \"0.0.0.0:8545\"%address = \"0.0.0.0:${CUSTOM_PORT}45\"%; s%^ws-address = \"0.0.0.0:8546\"%ws-address = \"0.0.0.0:${CUSTOM_PORT}46\"%" $HOME/.lava/config/app.toml
```

```bash
#Set config with new custom port
lavad config node tcp://localhost:${CUSTOM_PORT}57
```

```bash
# Create service file
sudo tee /etc/systemd/system/lavad.service > /dev/null <<EOF
[Unit]
Description=Lava node
After=network-online.target

[Service]

EOF
```

```bash
# Download latest chain snapshot
curl -L https://snapshots.kjnodes.com/lava/snapshot_latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.lava
```

```bash
# Enable and start service
sudo systemctl daemon-reload
sudo systemctl enable lavad
sudo systemctl start lavad && sudo journalctl -u lavad -f --no-hostname -o cat
```

```bash
# Check status
lavad status 2>&1 | jq .SyncInfo

#"catching_up": false means that the node is synchronized, we are waiting for complete synchronization
```

***Wallets***

```bash
# Create wallet
lavad keys add wallet
```

The wallet has been created. In the last line there will be a phrase that must be written down

```bash
# If the wallet was already there, restore it
lavad keys add wallet --recover

# Insert the seed phrase from your wallet
# If everything is correct, you will see your wallet data
```

***Validator***

Do not forget to create a profile on <https://keybase.io/> and set a profile photo there that will be imported by key and used for your validators.

```bash
lavad tx staking create-validator \
--amount 1000000ulava \
--pubkey $(lavad tendermint show-validator) \
--moniker "YOUR_MONIKER_NAME" \
--identity "YOUR_KEYBASE_ID" \
--details "YOUR_DETAILS" \
--website "YOUR_WEBSITE_URL" \
--chain-id lava-mainnet-1 \
--commission-rate 0.05 \
--commission-max-rate 0.20 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--from wallet \
--gas-adjustment 1.4 \
--gas auto \
--gas-prices 0.000000001ulava \
-y
```

**!!! Save priv\_validator\_key.json which is located in /root/.lava/config**
