How to run a synchronization node?

1. Configure environment

1.1 Use precompiled version

sudo mkdir dbc-chain-mainnet && cd dbc-chain-mainnet
wget https://github.com/DeepBrainChain/DeepBrainChain-MainChain/releases/download/v3.3/dbc_chain_linux_x64.tar.gz -O dbc_chain_linux_x64.tar.gz
tar xf dbc_chain_linux_x64.tar.gz 

1.2 Manual compilation

# Install dependencies
curl https://getsubstrate.io -sSf | bash -s -- --fast
source ~/.cargo/env

# Compile dbc-chain
git clone https://github.com/DeepBrainChain/DeepBrainChain-MainChain.git
cd DeepBrainChain-MainChain
git checkout v3.3
cargo build --release

2. Run the synchronization node

# Execute using precompilation
./dbc-chain --base-path ./db_data --pruning archive

# Manual compilation and execution:
./target/release/dbc-chain --base-path ./db_data --pruning archive

Port parameters:

--rpc-port 9933 # Specify the port on which your node listens for RPC. 9933 is the default value, so this parameter can also be ignored
--ws-port 9945 # Specify the port your node uses to listen to WebSocket. The default port is 9944
--port 30333 # Specify the node port you use to listen for p2p traffic. 30333 is the default port. You can ignore this flag if there is no need to change it.

Other parameters reference:

--ws-max-connections 2000
--in-peers 200
--out-peers 200

When encountering the phenomenon of 0 peers during synchronization, you need to specify bootnodes for synchronization. Old users can find it by querying the previous synchronization node logs. New users can try to specify --bootnodes /ip4/122.99.183.53/tcp/3308/p2p/12D3KooWDx4pgzT2RAPF12QkmiBZy6BUsTtPt7JgiYxgFm6Z5Hc5

3. Runtime Error Solution

	#If you encounter a startup error in Ubuntu 20.04 or earlier

#1. Equipment in China:
echo "deb http://mirrors.aliyun.com/ubuntu/ jammy main" >> /etc/apt/sources.list
sudo apt update
sudo apt install libc6 libstdc++6 -y
#2. Non-China equipment:
echo "deb http://archive.ubuntu.com/ubuntu/ jammy main" >> /etc/apt/sources.list
