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“’

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

Setup ssh for elys user replace YOUR_PUBLIC_SSH_KEY with your own!
sudo adduser elys --disabled-password -q
sudo usermod -aG sudo elys
sudo -u elys 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 elys
git clone https://github.com/elys-network/elys.git
cd elys
git checkout v0.38.2
make build

Latest commit : a5ba1a0bf9619199d5d07b2324629e6eb030d49a

Prepare binaries for cosmovisor
mkdir -p $HOME/.elys/cosmovisor/genesis/bin
mv build/elysd $HOME/.elys/cosmovisor/genesis/bin/
rm -rf build
Create symlinks
sudo ln -s $HOME/.elys/cosmovisor/genesis $HOME/.elys/cosmovisor/current -f
sudo ln -s $HOME/.elys/cosmovisor/current/bin/elysd /usr/local/bin/elysd -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/elys.service > /dev/null << EOF

EOF

Enable Service

Enable elys systemd service
sudo systemctl daemon-reload
sudo systemctl enable elys

Initialize Node

Setting node configuration
elysd config chain-id elystestnet-1
