Crossfi Testnet Full Node Installation Guide

Set Up Environment Variables

Define Node Name

Replace <Your_Nodename_Moniker> with your desired node name.

MYNODENAME="<Your_Nodename_Moniker>"
echo "export NODENAME=$MYNODENAME" >> $HOME/.bash_profile

Save Environment Variables

echo "export WALLET=wallet" >> $HOME/.bash_profile
echo "export CROSSFI_CHAIN_ID=crossfi-evm-testnet-1" >> $HOME/.bash_profile
source $HOME/.bash_profile

Update and Install Dependencies

Update System Packages

sudo apt update && sudo apt upgrade -y

Install Required Packages

sudo apt install curl build-essential git wget jq make gcc tmux net-tools ccze -y

Install Go

Check and Install Go if Not Present

if ! [ -x "$(command -v go)" ]; then
  ver="1.20.2"
  cd $HOME
  wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
  sudo rm -rf /usr/local/go
  sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
  rm "go$ver.linux-amd64.tar.gz"
  echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile
  source ~/.bash_profile
fi

Node Setup

Download and Prepare Binaries

cd $HOME
wget https://github.com/crossfichain/crossfi-node/releases/download/v0.3.0-prebuild3/crossfi-node_0.3.0-prebuild3_linux_amd64.tar.gz
tar -xvf crossfi-node_0.3.0-prebuild3_linux_amd64.tar.gz
chmod +x $HOME/go/bin/crossfid
mv $HOME/go/bin/crossfid $HOME/go/bin
rm -rf crossfi-node_0.3.0-prebuild3_linux_amd64.tar.gz

Initialize the Node with Chain ID

crossfid init $MYNODENAME --chain-id $CROSSFI_CHAIN_ID
rm -rf $HOME/.mineplex-chain
git clone https://github.com/crossfichain/testnet.git
mv $HOME/testnet/ $HOME/.mineplex-chain/

Fetch Configuration Files

wget --no-check-certificate http://crossfi-toolkit.coinsspor.com/genesis.json -O $HOME/.mineplex-chain/config/genesis.json
wget --no-check-certificate http://crossfi-toolkit.coinsspor.com/addrbook.json -O $HOME/.mineplex-chain/config/addrbook.json

Configure the Node

Set Minimum Gas Prices and Disable Indexing

sed -i 's|minimum-gas-prices =.*|minimum-gas-prices = "10000000000000mpx"|g' $HOME/.mineplex-chain/config/app.toml
sed -i -e "s/^indexer *=.*/indexer = \"null\"/" $HOME/.mineplex-chain/config/config.toml

Optimize Node Storage

pruning="custom"
pruning_keep_recent="100"
pruning_keep_every="0"
pruning_interval="10"
sed -i -e "s/^pruning *=.*/pruning = \"$pruning\"/" $HOME/.mineplex-chain/config/app.toml
sed -i -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \"$pruning_keep_recent\"/" $HOME/.mineplex-chain/config/app.toml
sed -i -e "s/^pruning-keep-every *=.*/pruning-keep-every = \"$pruning_keep_every\"/" $HOME/.mineplex-chain/config/app.toml
sed -i -e "s/^pruning-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.mineplex-chain/config/app.toml

Create System Service for Node

Set Up and Start Node Service

sudo tee /etc/systemd/system/crossfid.service > /dev/null <<EOF
[Unit]
Description=Crossfi Node
After=network-online.target
[Service]
User=$USER
ExecStart=$(which crossfid) start
Restart=on-failure
RestartSec=3
LimitNOFILE=4096
WorkingDirectory=$HOME/.mineplex-chain
[Install]
WantedBy=multi-user.target
EOF

Enable and Start Node Service

sudo systemctl daemon-reload
sudo systemctl enable crossfid
sudo systemctl start crossfid

Check Node Status

To ensure your node is running correctly, check its status:

sudo systemctl status crossfid

Or, to follow the node's live output:

sudo journalctl -u crossfid -f -o cat

Remember to replace <Your_Nodename_Moniker> with the actual name you want for your node before running the setup commands.
