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 crossfi user replace YOUR_PUBLIC_SSH_KEY with your own!

sudo adduser crossfi --disabled-password -q
sudo usermod -aG sudo crossfi
sudo -u crossfi 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 1.21.7

sudo rm -rf /usr/local/go
curl -Ls https://go.dev/dl/go1.21.7.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
wget https://github.com/crossfichain/crossfi-node/releases/download/v0.3.0-prebuild9/crossfi-node_0.3.0-prebuild9_linux_amd64.tar.gz && sudo mv crossfi-node_0.3.0-prebuild9_linux_amd64.tar.gz crossfid-v0.3.0-prebuild9.tar.gz && sudo tar -xvf crossfid-v0.3.0-prebuild9.tar.gz

Prepare binaries for cosmovisor

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

Create symlinks

sudo ln -s $HOME/.crossfid/cosmovisor/genesis $HOME/.crossfid/cosmovisor/current -f
sudo ln -s $HOME/.crossfid/cosmovisor/current/bin/crossfid /usr/local/bin/crossfid -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/crossfi.service > /dev/null << EOF
[Unit]
Description=crossfi node service
After=network-online.target
 
[Service]
User=$USER
ExecStart=$(which cosmovisor) run start
Restart=on-failure
RestartSec=10
LimitNOFILE=65535
Environment="DAEMON_HOME=$HOME/.crossfid"
Environment="DAEMON_NAME=crossfid"
Environment="UNSAFE_SKIP_BACKUP=true"
 
[Install]
WantedBy=multi-user.target
EOF

Enable Service

Enable crossfi systemd service

sudo systemctl daemon-reload
sudo systemctl enable crossfi

Initialize Node

Setting node configuration

crossfid config chain-id crossfi-evm-testnet-1
crossfid config keyring-backend test
crossfid config node tcp://localhost:23957

Initialize node

crossfid init $MONIKER --chain-id crossfi-evm-testnet-1

Download Genesis & Addrbook

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"|' \
