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

πŸ“’

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 nolus user replace YOUR_PUBLIC_SSH_KEY with your own!
sudo adduser nolus --disabled-password -q
sudo usermod -aG sudo nolus
sudo -u nolus 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 nolus-core
git clone https://github.com/Nolus-Protocol/nolus-core.git
cd nolus-core
git checkout v0.5.2
make build

Prepare binaries for cosmovisor
mkdir -p $HOME/.nolus/cosmovisor/genesis/bin
mv target/release/nolusd $HOME/.nolus/cosmovisor/genesis/bin/
Create symlinks
sudo ln -s $HOME/.nolus/cosmovisor/genesis $HOME/.nolus/cosmovisor/current -f
sudo ln -s $HOME/.nolus/cosmovisor/current/bin/nolusd /usr/local/bin/nolusd -f

Cosmovisor Setup

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