use fast sync in the config, if full needed, change this line

    SyncMode = "fast"

to

    SyncMode = "full"

Star Bash

To show full detail help info of all flags, type geth help or geth -h

• run.sh

    #!/usr/bin/env bash
    /data/bta/geth-linux-amd64 \
    --config /data/bta/config.toml  \
    --logpath /data/bta/logs \
    --verbosity 3  >> /data/bta/logs/systemd_chain_console.out 2>&1
  

if you need to use it as archive node, add：

    --syncmode full \
    --gcmode archive \
    
  

So：

    #!/usr/bin/env bash
    /data/bta/geth-linux-amd64 \
    --config /data/bta/config.toml  \
    --logpath /data/bta/logs \
    --syncmode full \
    --gcmode archive \
    --verbosity 3  >> /data/bta/logs/systemd_chain_console.out 2>&1
  

If there is no any network flags were provided, the node will connect the Btachain-mainnet by default. If you want to connect to Btachain-testnet, add:

    --testnet
