0G Storage Node Guide

Hello. In the previous tutorial, we implemented a validator with a light snapshot that took up little space. Now we want to implement a storage node on the same server.

To run the Node Validator, refer to the tutorial below. My suggestion is to run both.

0G Validator Node Guide

The prerequisites are the same. If you have more hard drives, you have less risk of running out of space.

• Memory: 16 GB RAM
• CPU: 4 cores
• Disk: 500GB / 1T NVME SSD
• Bandwidth: 500 MBps for Download / Upload

START

sudo apt-get update
sudo apt-get install clang cmake build-essential

If you are asked a question along the way, press the y key.

cd $HOME && \
ver="1.22.0" && \
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz" && \
sudo rm -rf /usr/local/go && \
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz" && \
rm "go$ver.linux-amd64.tar.gz" && \
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> ~/.bash_profile && \
source ~/.bash_profile && \
go version

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Enter

. "$HOME/.cargo/env"

git clone https://github.com/0glabs/0g-storage-node.git

cd 0g-storage-node
git checkout v0.8.4
git submodule update --init

sudo apt install cargo
sudo apt update
sudo apt install -y pkg-config libssl-dev

cargo build --release

It may take a while.

👾 If you receive a warning, you can use the following codes:

unset OPENSSL_DIR
cargo clean
cargo build --release

..

wget -O $HOME/0g-storage-node/run/config-testnet-turbo.toml https://josephtran.co/config-testnet-turbo.toml

printf '\033[34mEnter your private key: \033[0m' && read -s PRIVATE_KEY

So enter the private key here. I suggest you enter the validator wallet.
To get the private key, you can add 24 words in Metamask or OKX Wallet and then remove the private key.

sed -i 's|^\s*#\?\s*miner_key\s*=.*|miner_key = "'"$PRIVATE_KEY"'"|' $HOME/0g-storage-node/run/config-testnet-turbo.toml && echo -e "\033[32mPrivate key has been successfully added to the config file.\033[0m"

grep -E "^(network_dir|network_enr_address|network_enr_tcp_port|network_enr_udp_port|network_libp2p_port|network_discovery_port|rpc_listen_address|rpc_enabled|db_dir|log_config_file|log_contract_address|mine_contract_address|reward_contract_address|log_sync_start_block_number|blockchain_rpc_endpoint|auto_sync_enabled|find_peer_timeout)" $HOME/0g-storage-node/run/config-testnet-turbo.toml

Snapshot

We download snapshots to speed up syncing.

sudo systemctl stop zgs

sudo apt-get update
sudo apt-get install wget lz4 aria2 pv -y

cd $HOME
rm storage_0gchain_snapshot.lz4
aria2c -x 16 -s 16 -k 1M https://josephtran.co/storage_0gchain_snapshot.lz4

Skip this section if you don’t need it.

This process will take some time. If you think your internet might be down, redirect it to screen.

apt install screen 

screen -S snapshot

Now run the snapshot download commands.

    sleep 5;
done

is ok Over time, your peer numbers should increase.

Pay attention, so far only these tasks were unlocked and we did them. In the future, they may have many tasks to do. I don’t think it’s too hard. This article will be updated if they put hard tasks. We can follow the announcements on Telegram and Twitter
