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"

Set minimum gas price, seeds and peers

sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \"0.005mand\"/;" ~/.mande-chain/config/app.toml
sed -i -e "s/^filter_peers *=.*/filter_peers = \"true\"/" $HOME/.mande-chain/config/config.toml
peers="[email protected]:26656,[email protected]:26656"
sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \"$peers\"/" $HOME/.mande-chain/config/config.toml
seeds="[email protected]:26656"
sed -i.bak -e "s/^seeds =.*/seeds = \"$seeds\"/" $HOME/.mande-chain/config/config.toml

Disable indexing

indexer="null" && \
sed -i -e "s/^indexer *=.*/indexer = \"$indexer\"/" $HOME/.mande-chain/config/config.toml

Update ~/.mande-chain/config/config.toml

send_rate = 20000000
recv_rate = 20000000
max_packet_msg_payload_size = 10240
flush_throttle_timeout = "50ms"
mempool.size = 10000
create_empty_blocks = false

Config pruning

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

Create service

sudo tee /etc/systemd/system/mande-chaind.service > /dev/null <<EOF

Register and start service

sudo systemctl daemon-reload
sudo systemctl enable mande-chaind
sudo systemctl restart mande-chaind && sudo journalctl -u mande-chaind -f -o cat
