A) Setup
1) Install Golang (go)
1.1) Remove any existing installation of go
sudo rm -rf /usr/local/go
1.2) Install latest/required Go version (installing go1.16.7)
curl https://dl.google.com/go/go1.16.7.linux-amd64.tar.gz | sudo tar -C/usr/local -zxvf -
1.3) Update env variables to include go
cat <<'EOF' >>$HOME/.profile
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
EOF
source $HOME/.profile
1.4) Check the version of go installed
go version
2) Install required software packages
sudo apt-get install git curl build-essential make jq -y
3) Install ethermint
git clone https://github.com/vulcanize/ethermint.git
cd ethermint
git fetch --all
git checkout v0.1.0-dev
make install
4) Verify your installation
ethermintd version --long
On running the above command, you should see a similar response like this. Make sure that the version and commit hash are accurate
name: ethermint
server_name: ethermintd
5) Initialize Node
Not required if you have already initialized before
ethermintd init <your-node-moniker> --chain-id ethermint_9000-1
On running the above command, node will be initialized with default configuration. (config files will be saved in node's default home directory (~/.ethermintd/config)
NOTE: Backup node and validator keys . You will need to use these keys at a later point in time.
Execute below instructions only after publishing of final genesis file
genesis file will be published to vulcanize//testnets/ethermint_9000-1
B) Starting Node
TBU
## 3) Start the Node
#### 3.1) Start node as `systemctl` service
3.1.1) Create the service file
sudo tee /etc/systemd/system/ethermintd.service > /dev/null <<EOF [Unit] Description=EthermintD Daemon After=network-online.target
[Service] User=$USER ExecStart=$(which ethermintd) start --gql-playground --gql-server Restart=always RestartSec=3 LimitNOFILE=65535
[Install] WantedBy=multi-user.target EOF
3.1.2) Load service and start
sudo systemctl daemon-reload sudo systemctl enable ethermintd sudo systemctl start ethermintd
3.1.3) Check status of service
sudo systemctl status ethermintd
`NOTE:`
A helpful command here is `journalctl` that can be used to:
a) check logs
journalctl -u ethermintd
b) most recent logs
journalctl -xeu ethermintd
c) logs from previous day
journalctl --since "1 day ago" -u ethermintd
d) Check logs with follow flag
journalctl -f -u ethermintd
