## ***Automatic Installation***

```bash
source <(curl -s https://raw.githubusercontent.com/validexisinfra/Juno/main/installmain.sh)
```

## ***Manual Installation***

```bash
# Come up with the name of your node and replace it instead <your_moniker>
MONIKER=<your_moniker>
```

<pre class="language-bash"><code class="lang-bash"># Download binary files
<strong>cd $HOME
</strong>rm -rf juno
git clone https://github.com/CosmosContracts/juno juno
cd juno
git checkout v29.0.0
make install
</code></pre>

<pre class="language-bash"><code class="lang-bash"># Set node configuration
<strong>junod config set client chain-id juno-1
</strong>junod config set client keyring-backend file
junod config set client node tcp://localhost:26657

# Initialize the node
junod init $MONIKER --chain-id=juno-1
</code></pre>

```bash
# Download genesis and addrbook
wget -L -O $HOME/.juno/config/genesis.json https://server-1.stavr.tech/Mainnet/Juno/genesis.json
wget -O $HOME/.juno/config/addrbook.json "https://server-1.stavr.tech/Mainnet/Juno/addrbook.json"
```

***Setup config***

```bash
# Set seeds and peers
sed -i -e "s/^filter_peers *=.*/filter_peers = \"true\"/" $HOME/.juno/config/config.toml
external_address=$(wget -qO- eth0.me) 
sed -i.bak -e "s/^external_address *=.*/external_address = \"$external_address:26656\"/" $HOME/.juno/config/config.toml
peers=""
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.juno/config/config.toml
seeds=""

# Set minimum gas price, enable prometheus and disable indexing
sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.025ujuno\"/;" $HOME/.juno/config/app.toml
sed -i -e "s/prometheus = false/prometheus = true/" $HOME/.juno/config/config.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.juno/config/config.toml

# Config pruning
pruning="custom"
pruning_keep_recent="1000"
pruning_keep_every="0"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.juno/config/app.toml

sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.juno/config/app.toml
```

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

You can change value CUSTOM\_PORT=165 To any other ports

```bash
CUSTOM_PORT=165
```

```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\"%" $HOME/.juno/config/config.toml
sed -i -e "s%^address = \"tcp://localhost:1317\"%address = \"tcp://localhost:${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/.juno/config/app.toml
```

<pre class="language-bash"><code class="lang-bash">#Set config with new custom port
<strong>junod config node tcp://localhost:${CUSTOM_PORT}57
</strong></code></pre>

```bash
# Create service file

<pre class="language-bash"><code class="lang-bash"># Enable and start service
sudo systemctl daemon-reload
sudo systemctl enable junod
<strong>sudo systemctl restart junod &#x26;&#x26; sudo journalctl -u junod -fo cat
</strong></code></pre>

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

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

***Wallets***

```bash
# Create wallet
junod 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
junod 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
junod tx staking create-validator \
--amount 1000000ujuno \
--pubkey=$(junod tendermint show-validator) \
--moniker "YOUR_MONIKER_NAME" \
--identity "YOUR_KEYBASE_ID" \
--details "YOUR_DETAILS" \
--website "YOUR_WEBSITE_URL" \
--chain-id juno-1 \
--commission-rate="0.1" \
--commission-max-rate="0.1" \
--commission-max-change-rate="0.1" \
--min-self-delegation="1" \
--from wallet \
--gas 350000 \
-y
```

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