Installation

Hardware Requirement

1. Install dependencies

sudo apt-get update
sudo apt-get install cmake

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. Download the source code

git clone -b v1.0.0-testnet https://github.com/0glabs/0g-da-client.git

4. Build combined server

cd $HOME/0g-da-client
git stash
git fetch --all --tags
git checkout f8db250
git submodule update --init

Configuration

nano /root/0g-da-client/disperser/Makefile

Replace your info at run_combined function:

--chain.rpc http://YOUR_RPC

--chain.private-key YOUR_PRIVATE_KEY

--encoder-socket YOUR_DA_NODE_IP:34000

Sample Makefile:

5. Creat service

sudo tee /etc/systemd/system/0gdacli.service > /dev/null <<EOF
[Unit]
Description=0G-DA-ClI Node
After=network.target

[Service]
User=root
WorkingDirectory=/root/0g-da-client/disperser
ExecStart=/usr/bin/make run_combined
Restart=always
RestartSec=10
LimitNOFILE=65535
Environment="PATH=/usr/local/go/bin:/usr/bin:/bin"

[Install]
WantedBy=multi-user.target
EOF

6. Start service

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

Check log:

sudo journalctl -u 0gdacli -f -o cat

# Stop Service and Delete node:

sudo systemctl stop 0gdacli
sudo systemctl disable 0gdacli
sudo rm /etc/systemd/system/0gdacli.service
rm -rf $HOME/0g-da-client
