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

📢

While this step is optional, it is strongly recommended for those running on the mainnet to take a closer look, as it plays a crucial role in ensuring basic security. If you don't want to, you can skip ahead to configure moniker.

Setup ssh for orai user replace YOUR_PUBLIC_SSH_KEY with your own!

sudo adduser orai --disabled-password -q
sudo usermod -aG sudo orai
sudo -u orai 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 1.21.1

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.21.1.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 orai
git clone https://github.com/oraichain/orai
cd orai/orai
git checkout v0.42.4
make build

Latest commit : fbc32fd41ec5633edd2336a01209225a6b4c837a

Prepare binaries for cosmovisor

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

Create symlinks

sudo ln -s $HOME/.oraid/cosmovisor/genesis $HOME/.oraid/cosmovisor/current -f
sudo ln -s $HOME/.oraid/cosmovisor/current/bin/oraid /usr/local/bin/oraid -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/orai.service > /dev/null << EOF
[Unit]
Description=orai node service
After=network-online.target
 
[Service]
User=$USER
ExecStart=$(which cosmovisor) run start --home $HOME/.oraid

Environment="DAEMON_HOME=$HOME/.oraid"
Environment="DAEMON_NAME=oraid"
Environment="UNSAFE_SKIP_BACKUP=true"
 
[Install]
WantedBy=multi-user.target
EOF

Enable Service

Enable orai systemd service

sudo systemctl daemon-reload
sudo systemctl enable orai
