Node Settup

Download and prepare the 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.nodevism.com/genesis.json -O $HOME/.mineplex-chain/config/genesis.json
wget --no-check-certificate http://crossfi-toolkit.nodevism.com/addrbook.json -O $HOME/.mineplex-chain/config/addrbook.json

Configuration 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

Optimistion 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-interval *=.*/pruning-interval = \"$pruning_interval\"/" $HOME/.mineplex-chain/config/app.toml

Create Service System

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 the service

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

Check Node Status

sudo systemctl status crossfid

Check logs

sudo systemctl status crossfid
