Running a TomoX Mongodb Fullnode

This guide shows how to run a TomoX MongoDb Fullnode. To run the fullnode, you need to have MongoDb instance that enable replica set.
Start MongoDB
In this tutorial, we will run a mongo instance with Docker. Run this command:
docker run -d -p 27017:27017 --name mongodb \
    --hostname mongodb mongo:4.2 --replSet rs0
Enable Mongodb replica set:
docker exec -it mongodb mongo --eval "rs.initiate()"
Run a fullnode
Download tomo version 2.0+ from TomoChain Github Release page​
E.g:
wget https://github.com/tomochain/tomochain/releases/download/v2.1.0-beta/tomo-linux-amd64 -O tomo
chmod +x tomo
sudo mv tomo /usr/bin/
Create a coinbase address:
tomo account new
Init genesis block: Testnet
curl -L https://raw.githubusercontent.com/tomochain/tomochain/testnet/genesis/testnet.json -o genesis.json
tomo init genesis.json
Then run the node:
Testnet
NODENAME=[your_node_name]
tomo \
    --bootnodes "enode://ba966140e161ad416a7bd7c75dc695e0a41232723e2b19cbbf651883ef5e8f2528801b17b9d63152814d219a58a4fcc3e3c877486e64057523f6714092348efa@195.154.150.210:30301" \
    --networkid 89 \
    --rpc --rpccorsdomain "*" --rpcaddr 0.0.0.0 --rpcport 8545 --rpcvhosts "*" \
    --ws --wsaddr 0.0.0.0 --wsport 8546 --wsorigins "*" \
    --rpcapi "personal,db,eth,net,web3,txpool,miner,tomox" \
    --announce-txs \
    --tomo-testnet \
    --tomox.dbengine "mongodb" \
    --ethstats "${NODENAME}:9tlu4EymcTrEzaqWpSxh3KSa926au8@stats.testnet.tomochain.com"
You node will sync the data from TomoChain network, you need to wait until your node catch up the latest block. You can check the status in the logs or the stats page.
To save your time, you should download chaindata snapshot and override your chaindata.
Troubleshoot
Fatal: Failed to write genesis block
You already inited genesis block for the default datadir. So you need to use another datadir by --datadir
tomo account new --datadir [YOUR_DATADIR]
tomo init genesis.json --datadir [YOUR_DATADIR]
Example
Testnet
wget https://github.com/tomochain/tomochain/releases/download/v2.0.0-beta/tomo-linux-amd64 -O tomo
chmod +x tomo
sudo mv tomo /usr/bin/
tomo --version
tomo version
curl -L https://raw.githubusercontent.com/tomochain/tomochain/master/genesis/testnet.json -o genesis.json
tomo init genesis.json 
tomo account new --datadir /tmp/chaindata
tomo init genesis.json --datadir /tmp/chaindata/
NODENAME=testnode02
tomo \
    --bootnodes "enode://ba966140e161ad416a7bd7c75dc695e0a41232723e2b19cbbf651883ef5e8f2528801b17b9d63152814d219a58a4fcc3e3c877486e64057523f6714092348efa@195.154.150.210:30301" \

    --datadir /tmp/chaindata/
Testnet chaindata snapshot
To speed up syncing chaindata, you can download chaindata snapshot and override your local chaindata.
Download: Testnet chaindata​
E.g:
# Download
wget -c https://chaindata-testnet.s3-ap-southeast-1.amazonaws.com/chaindata-testnet.tar
​
# Uncompress
tar xvf chaindata-testnet.tar
