☑️0G Storage KV

Recommended Hardware: 8 Cores, 16GB RAM, 260GB of storage (NVME)

Ensure Rust is Installed

Check if Rust is installed by running:

rustc --version

If Rust is not installed, follow this section to install it.

Build Storage KV from source code

git clone https://github.com/0glabs/0g-storage-kv.git
cd 0g-storage-kv
git submodule update --init
cargo build --release

Copy the example config_example.toml & rename to config.toml

cp $HOME/0g-storage-kv/run/config_example.toml $HOME/0g-storage-kv/run/config.toml

Set parameters for Storage Node

STORAGE_PORT=$(grep -oP '(?<=rpc_listen_address = "0.0.0.0:)\d+(?=")' $HOME/0g-storage-node/run/config.toml)
ZGS_LOG_SYNC_BLOCK=$(grep -oP '(?<=log_sync_start_block_number = )\d+' $HOME/0g-storage-node/run/config.toml)
STORAGE_RPC_ENDPOINT=http://$(wget -qO- eth0.me):$STORAGE_PORT
BLOCKCHAIN_RPC_ENDPOINT=$(sed -n 's/blockchain_rpc_endpoint = "\([^"]*\)"/\1/p' $HOME/0g-storage-node/run/config.toml)
LOG_CONTRACT_ADDRESS=$(sed -n 's/log_contract_address = "\([^"]*\)"/\1/p' $HOME/0g-storage-node/run/config.toml)
MINE_CONTRACT_ADDRESS=$(sed -n 's/mine_contract_address = "\([^"]*\)"/\1/p' $HOME/0g-storage-node/run/config.toml)
JSON_PORT=$(sed -n '/\[json-rpc\]/,/^address/ s/address = "0.0.0.0:\([0-9]*\)".*/\1/p' $HOME/.0gchain/config/app.toml)
JSON_RPC_ENDPOINT=http://$(wget -qO- eth0.me):$JSON_PORT

echo -e "\nSTORAGE_RPC_ENDPOINT: $STORAGE_RPC_ENDPOINT\nLOG_CONTRACT_ADDRESS: $LOG_CONTRACT_ADDRESS\nMINE_CONTRACT_ADDRESS: $MINE_CONTRACT_ADDRESS\nBLOCKCHAIN_RPC_ENDPOINT: $BLOCKCHAIN_RPC_ENDPOINT\nJSON_RPC_ENDPOINT: $JSON_RPC_ENDPOINT\nZGS_LOG_SYNC_BLOCK: $ZGS_LOG_SYNC_BLOCK\n\nScript by \033[35mNodeCattel\033[0m"

Use sed to update these parameters:

sed -i "s|rpc_listen_address = .*|rpc_listen_address = \"0.0.0.0:6789\"|" $HOME/0g-storage-kv/run/config.toml
sed -i "s|zgs_node_urls = .*|zgs_node_urls = \"$STORAGE_RPC_ENDPOINT\"|" $HOME/0g-storage-kv/run/config.toml
sed -i "s|log_config_file = .*|log_config_file = \"$HOME/0g-storage-kv/run/log_config\"|" $HOME/0g-storage-kv/run/config.toml
sed -i "s|blockchain_rpc_endpoint = .*|blockchain_rpc_endpoint = \"$BLOCKCHAIN_RPC_ENDPOINT\"|" $HOME/0g-storage-kv/run/config.toml
sed -i "s|log_contract_address = .*|log_contract_address = \"$LOG_CONTRACT_ADDRESS\"|" $HOME/0g-storage-kv/run/config.toml
sed -i "s|log_sync_start_block_number = .*|log_sync_start_block_number = $ZGS_LOG_SYNC_BLOCK|" $HOME/0g-storage-kv/run/config.toml

Create zgs-kv service (storage KV) to run in the background

sudo tee /etc/systemd/system/zgs-kv.service > /dev/null <<EOF

Start Storage KV node

sudo systemctl daemon-reload && \
sudo systemctl enable zgs-kv && \
sudo systemctl restart zgs-kv

View Storage KV log

sudo journalctl -u zgs-kv.service -f

Stop Storage KV node - (if you wish to stop the service)

sudo systemctl stop zgs-kv
