Manual Installation

Let's explore the manual installation process as we set up a node with Cosmovisor!

Install Dependencies

Update system package and install build tools

sudo apt -q update
sudo apt -qy install curl git jq lz4 build-essential fail2ban ufw
sudo apt -qy upgrade

Secure Setup

📢

This step is optional, and you can choose to skip ahead to configure moniker.

Setup ssh for xion user replace YOUR_PUBLIC_SSH_KEY with your own!

sudo adduser xion --disabled-password -q
sudo usermod -aG sudo xion
sudo -u xion bash -c 'mkdir -p ~/.ssh && echo "YOUR_PUBLIC_SSH_KEY" >> ~/.ssh/authorized_keys && chmod 700 ~/.ssh && chmod 600 ~/.ssh/authorized_keys'

Configure Moniker

Replace <your-moniker-name> with your own validator name

MONIKER="<your-moniker-name>"

Install Go

install go version 1.21.3

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.21.3.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)

Build Binaries

Cloning project repository & Compile binaries

cd $HOME
rm -rf xion
git clone https://github.com/burnt-labs/xion.git
cd xion
git checkout v11.0.1
make build

Latest commit : 0fa1ea9d9130b0955ef2fd9c25a0eab0099327aa

Prepare binaries for cosmovisor

mkdir -p $HOME/.xiond/cosmovisor/genesis/bin
mv build/xiond $HOME/.xiond/cosmovisor/genesis/bin/
rm -rf build

Create symlinks

sudo ln -s $HOME/.xiond/cosmovisor/genesis $HOME/.xiond/cosmovisor/current -f
sudo ln -s $HOME/.xiond/cosmovisor/current/bin/xiond /usr/local/bin/xiond -f

Cosmovisor Setup

Install cosmovisor

go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@v1.5.0

Create Service

Create a systemd service

sudo tee /etc/systemd/system/xion.service > /dev/null << EOF
[Unit]
Description=xion node service
After=network-online.target
 
[Service]
User=$USER
ExecStart=$(which cosmovisor) run start

[Install]
WantedBy=multi-user.target
EOF

Enable Service

Enable xion systemd service

sudo systemctl daemon-reload
sudo systemctl enable xion

Initialize Node

Setting node configuration

xiond config chain-id xion-testnet-1
xiond config keyring-backend test
xiond config node tcp://localhost:22357

Initialize node

xiond init $MONIKER --chain-id xion-testnet-1

Configure Seeds

Setting up a seed peers

sed -i -e "s|^seeds *=.*|seeds = \"d1d43cc7c7aef715957289fd96a114ecaa7ba756@testnet-seeds.nodex.one:22310\"|" $HOME/.xiond/config/config.toml

Pruning Setting

Configure pruning setting

sed -i \
  -e 's|^pruning *=.*|pruning = "custom"|' \
  -e 's|^pruning-keep-recent *=.*|pruning-keep-recent = "100"|' \
  -e 's|^pruning-keep-every *=.*|pruning-keep-every = "0"|' \
  -e 's|^pruning-interval *=.*|pruning-interval = "19"|' \
  $HOME/.xiond/config/app.toml

Custom Port

Please note that updating the port is optional!

Configure a custom port

sed -i -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:22358\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:22357\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:22360\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:22356\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":22366\"%" $HOME/.xiond/config/config.toml
