Storage KV Node

1. Install Rust

2. Download the source code

rm -rf 0g-storage-kvgit clone -b v1.2.1 https://github.com/0glabs/0g-storage-kv.git

3. Build the source code

cd 0g-storage-kvgit submodule update --init --recursivecargo build --release

4. Copy the config_example.toml to config.toml and update the parameters

cp ~/0g-storage-kv/run/config_example.toml ~/0g-storage-kv/run/config.tomlnano ~/0g-storage-kv/run/config.toml

5. Creat service

6. Start service

sudo systemctl daemon-reload && \sudo systemctl enable 0gkv && \sudo systemctl start 0gkv && \sudo systemctl status 0gkv

Check log:

sudo journalctl -u 0gkv -f -o cat

# Stop & Remove node

sudo systemctl stop 0gkv

sudo systemctl disable 0gkvsudo rm /etc/systemd/system/0gkv.servicerm -rf $HOME/0g-storage-kv
