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

Install dependencies for building from source

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

2. install go

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

3. install rustup

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

4. set vars

PLEASE INPUT YOUR STORAGE NODE URL (http://STORAGE_NODE_IP:5678,http://STORAGE_NODE_IP:5679) , YOUR JSON RPC ENDPOINT (VALIDATOR_NODE_IP:8545) OR YOU CAN OUR ENDPOINTS PLEASE CHECK README

read -p "Enter json-rpc: " BLOCKCHAIN_RPC_ENDPOINT && echo "Current json-rpc: $BLOCKCHAIN_RPC_ENDPOINT" &&
read -p "Enter storage node urls: " ZGS_NODE && echo "Current storage node urls: $ZGS_NODE" &&
echo 'export ZGS_LOG_SYNC_BLOCK="802"' >> ~/.bash_profile
echo "export ZGS_NODE=\"$ZGS_NODE\"" >> ~/.bash_profile
echo 'export LOG_CONTRACT_ADDRESS="0x8873cc79c5b3b5666535C825205C9a128B1D75F1"' >> ~/.bash_profile
echo 'export MINE_CONTRACT="0x85F6722319538A805ED5733c5F4882d96F1C7384"' >> ~/.bash_profile
echo "export BLOCKCHAIN_RPC_ENDPOINT=\"$BLOCKCHAIN_RPC_ENDPOINT\"" >> ~/.bash_profile

source ~/.bash_profile

echo -e "\n\033[31mCHECK YOUR STORAGE KV VARIABLES\033[0m\n\nZGS_NODE: $ZGS_NODE\nLOG_CONTRACT_ADDRESS: $LOG_CONTRACT_ADDRESS\nMINE_CONTRACT: $MINE_CONTRACT\nZGS_LOG_SYNC_BLOCK: $ZGS_LOG_SYNC_BLOCK\nBLOCKCHAIN_RPC_ENDPOINT: $BLOCKCHAIN_RPC_ENDPOINT\n\n"

5. download binary

cd $HOME
git clone https://github.com/0glabs/0g-storage-kv.git
cd $HOME/0g-storage-kv
git fetch
git checkout tags/v1.1.0-testnet
git submodule update --init
sudo apt install cargo

then build it

cargo build --release

6. copy a config_example.toml file

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

7. update storage kv configuration

sed -i '
s|^\s*#\?\s*rpc_enabled\s*=.*|rpc_enabled = true|
s|^\s*#\?\s*rpc_listen_address\s*=.*|rpc_listen_address = "0.0.0.0:6789"|
s|^\s*#\?\s*db_dir\s*=.*|db_dir = "db"|
s|^\s*#\?\s*kv_db_dir\s*=.*|kv_db_dir = "kv.DB"|
s|^\s*#\?\s*log_config_file\s*=.*|log_config_file = "log_config"|
s|^\s*#\?\s*log_contract_address\s*=.*|log_contract_address = "'"$LOG_CONTRACT_ADDRESS"'"|
s|^\s*#\?\s*zgs_node_urls\s*=.*|zgs_node_urls = "'"$ZGS_NODE"'"|
s|^\s*#\?\s*mine_contract_address\s*=.*|mine_contract_address = "'"$MINE_CONTRACT"'"|
s|^\s*#\?\s*log_sync_start_block_number\s*=.*|log_sync_start_block_number = '"$ZGS_LOG_SYNC_BLOCK"'|
s|^\s*#\?\s*blockchain_rpc_endpoint\s*=.*|blockchain_rpc_endpoint = "'"$BLOCKCHAIN_RPC_ENDPOINT"'"|
' $HOME/0g-storage-kv/run/config.toml

8. create service

sudo tee /etc/systemd/system/zgskv.service > /dev/null <<EOF
[Unit]
Description=ZGS KV
After=network.target

[Service]
User=$USER
WorkingDirectory=$HOME/0g-storage-kv/run
ExecStart=$HOME/0g-storage-kv/target/release/zgs_kv --config $HOME/0g-storage-kv/run/config.toml
Restart=on-failure
RestartSec=10
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

9. start the node

sudo systemctl daemon-reload && \
sudo systemctl enable zgskv && \
sudo systemctl start zgskv && \
sudo systemctl status zgskv

10. check the logs

sudo journalctl -u zgskv -fn 100 -o cat

MAKE SURE YOUR LOGS HAS THE SYNCED TX_SEQ(tx sequence) VALUE, CHECK STORAGE SCAN

delete the node

sudo systemctl stop zgskv
sudo systemctl disable zgskv
sudo rm -rf /etc/systemd/system/zgskv.service
sudo rm -rf 0g-storage-kv
