Install Gmet
This document describes the configuration and build of gmet for installing the Metadium EN node. This installation process is only necessary if you build directly from the source code and not when using pre-built files from GitHub.
Download Source Code
The source code for go-metadium is publicly available on the Metadium GitHub, allowing everyone to access it. Download it as follows:
git clone https://github.com/METADIUM/go-metadium.git
Build Gmet
Gmet in Metadium supports rocksdb and leveldb, and building can be done by selecting each version using the USE_ROCKSDB option. Each version has a different format for the generated chain data, so it is essential to confirm the DB version to be used before proceeding.
Below is the command for building, written based on the Ubuntu operating system recommended by Metadium.
Dependency
sudo apt-get update
sudo apt-get install -y build-essential golang
Rocksdb only
sudo apt-get install -y libsnappy-dev libjemalloc-dev
cd /usr/lib/x86_64-linux-gnu/
sudo ln -sf libjemalloc.so.2 libjemalloc.so.1xx
Download source code
git clone https://github.com/METADIUM/go-metadium.git
cd go-metadium
Make-build (in case of rocksdb)
make USE_ROCKSDB=YES
Make-build (in case of leveldb)
make USE_ROCKSDB=NO
Copy and untar "build" to $GMET_HOME
GMET_HOME='/opt/meta'
sudo mkdir -p $GMET_HOME
sudo chown $USER:$USER $GMET_HOME
cp build/metadium.tar.gz $GMET_HOME/
cd $GMET_HOME
tar xvzf metadium.tar.gz
Start gmet
$GMET_HOME/bin/gmet.sh start
Check log
tail -F $GMET_HOME/logs/log
Configuration
Once the build is complete, you can run the gmet node using the gmet.sh script. The gmet.sh script allows you to specify parameters for running the gmet node by creating a .rc configuration file, simplifying the process.
# vi $GMET_HOME/.rc
PORT=8588
DISCOVER=1 # 1 for enable discovery mode, 0 for disable discovery mode
TESTNET=1 # 1 for Testnet or remove this line for Mainnet
SYNC_MODE=full # snap, full or archive
GMET_OPTS="--maxpeers=100" # setup additional options
