How To Install Full Node Mande Chain Testnet 2
Setting up vars
Your Nodename (validator) that will shows in explorer
NODENAME=<Your_Nodename_Moniker>
Save variables to system
echo "export NODENAME=$NODENAME" >> $HOME/.bash_profile
if [ ! $WALLET ]; then
echo "export WALLET=wallet" >> $HOME/.bash_profile
fi
echo "export MANDE_CHAIN_ID=mande-testnet-2" >> $HOME/.bash_profile
source $HOME/.bash_profile
Update packages
sudo apt update && sudo apt upgrade -y
Install dependencies
sudo apt install curl build-essential git wget jq make gcc tmux net-tools -y
Install go
ver="1.19" && \
wget "https://golang.org/dl/go$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" >> $HOME/.bash_profile && \
source $HOME/.bash_profile && \
go version
Download and build binaries
cd $HOME
wget https://snapshot3.konsortech.xyz/mande/mande-chaind.tar.gz
tar -xzvf mande-chaind.tar.gz && chmod +x mande-chaind
mv mande-chaind /usr/local/go/bin/
Install Wasm Library (Skip this, this is only if you got failed to start mande binary libwasmvm.x86_64.so: cannot open shared)
cd $HOME
wget https://snapshot3.konsortech.xyz/mande/libwasmvm.x86_64.so
chmod +x libwasmvm.x86_64.so
mv libwasmvm.x86_64.so /usr/lib/
Init app
mande-chaind init $NODENAME --chain-id $MANDE_CHAIN_ID
Download configuration
wget -O $HOME/.mande-chain/config/genesis.json "https://raw.githubusercontent.com/mande-labs/testnet-2/main/genesis.json"
