Node Installation

Minumum Requirements

• 4 or more physical CPU cores.
• At least 100 GB of SSD disk storage.
• At least 8 GB of memory (RAM).
• At least 50 mbps network bandwidth.

Custom Configuration _(optional)

• Custom user

sudo adduser mantra
sudo adduser mantra sudo
su - mantra

• Custom Port 
  

PORT=44
echo "export PORT=${PORT}" >> $HOME/.bash_profile
source $HOME/.bash_profile

sudo apt -q update
sudo apt -qy upgrade
sudo apt -qy install curl git jq wget unzip lz4 build-essential

Install GO_{(ver. 20.5)}

For new Go Installation, run this command

sudo rm -rf /usr/local/go && \
curl -Ls https://go.dev/dl/go1.20.5.linux-amd64.tar.gz | sudo tar -xzf - -C /usr/local && \
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile && \
source $HOME/.bash_profile && \
go version

If you already install GO on your previous project, run this command

echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile && \
source $HOME/.bash_profile && \
go version

Installing Binary

cd $HOME
wget https://github.com/MANTRA-Finance/public/raw/main/mantrachain-testnet/mantrachaind-linux-amd64.zip
unzip mantrachaind-linux-amd64.zip
sudo mv mantrachaind /usr/local/bin

Init Generation

Replace moniker_name with your own moniker name

mantrachaind config chain-id mantrachain-testnet-1
mantrachaind config keyring-backend test
mantrachaind init moniker_name --chain-id mantrachain-testnet-1

Download Genesis and Addrbook

wget -O $HOME/.mantrachain/config/genesis.json https://raw.githubusercontent.com/MANTRA-Finance/public/main/mantrachain-testnet/genesis.json

Set Port app.toml and config.toml

This Step If you running custom port, if you running default port, skip this step

mantrachaind config node tcp://localhost:${PORT}657
sed -i.bak -e "s%^proxy_app = \"tcp://127.0.0.1:26658\"%proxy_app = \"tcp://127.0.0.1:${PORT}658\"%; s%^laddr = \"tcp://127.0.0.1:26657\"%laddr = \"tcp://127.0.0.1:${PORT}657\"%; s%^pprof_laddr = \"localhost:6060\"%pprof_laddr = \"localhost:${PORT}060\"%; s%^laddr = \"tcp://0.0.0.0:26656\"%laddr = \"tcp://0.0.0.0:${PORT}656\"%; s%^prometheus_listen_addr = \":26660\"%prometheus_listen_addr = \":${PORT}660\"%" $HOME/.mantrachain/config/config.toml
sed -i.bak -e "s%^address = \"tcp://0.0.0.0:1317\"%address = \"tcp://0.0.0.0:${PORT}317\"%; s%^address = \":8080\"%address = \":${PORT}080\"%; s%^address = \"0.0.0.0:9090\"%address = \"0.0.0.0:${PORT}090\"%; s%^address = \"0.0.0.0:9091\"%address = \"0.0.0.0:${PORT}091\"%" $HOME/.mantrachain/config/app.toml
sed -i.bak -e "s%^address = \"tcp://localhost:1317\"%address = \"tcp://localhost:${PORT}317\"%; s%^address = \":8080\"%address = \":${PORT}080\"%; s%^address = \"localhost:9090\"%address = \"localhost:${PORT}090\"%; s%^address = \"localhost:9091\"%address = \"localhost:${PORT}091\"%" $HOME/.mantrachain/config/app.toml

Set Config Pruning

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

Create Service

sudo tee /etc/systemd/system/mantrachaind.service > /dev/null <<EOF
[Unit]
Description=Mantrachain testnet node
After=network-online.target
[Service]
User=$USER
ExecStart=$(which mantrachaind) start

EOF

Register And Start Service

sudo systemctl daemon-reload
sudo systemctl enable mantrachaind
sudo systemctl restart mantrachaind && sudo journalctl -fu mantrachaind -o cat
