```

## **Create zgs service (storage node) for your node to run in the background**

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

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

[Install]
WantedBy=multi-user.target
EOF
```

**Start Storage node**

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

#### Show logs by date

* full logs command

```
tail -f ~/0g-storage-node/run/log/zgs.log.$(TZ=UTC date +%Y-%m-%d)
```

* tx\_seq-only logs command

```
tail -f ~/0g-storage-node/run/log/zgs.log.$(TZ=UTC date +%Y-%m-%d) | grep tx_seq:
```

* minimized-logs command

```
tail -f ~/0g-storage-node/run/log/zgs.log.$(TZ=UTC date +%Y-%m-%d) | grep -v "discv5\|network\|connect\|16U\|nounce"
```

* check your storage node through rpc

```
while true; do 
    response=$(curl -s -X POST http://localhost:5678 -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"zgs_getStatus","params":[],"id":1}')
    logSyncHeight=$(echo $response | jq '.result.logSyncHeight')
    connectedPeers=$(echo $response | jq '.result.connectedPeers')
    echo -e "logSyncHeight: \033[32m$logSyncHeight\033[0m, connectedPeers: \033[34m$connectedPeers\033[0m"
    sleep 5; 
done
```

## Test Stoarge Node with storage CLI

Build Storage CLI with source code

```
git clone -b v0.5.1 https://github.com/0glabs/0g-storage-client.git
cd $HOME/0g-storage-client
git stash
git fetch --all --tags
git checkout e283cdbfef2f3e5c94f97ef4c1815b464851f399 
git submodule update --init
go build
```

Create upload.sh

```
nano $HOME/upload.sh
```

```
# Generate the file
  size=$(shuf -i 10240-51200 -n 1)
  filename=$(head /dev/urandom | tr -dc A-Za-z0-9 | head -c 10).md
  /root/0g-storage-client/./0g-storage-client gen --size $size --file ${filename}

# Upload the file
  /root/0g-storage-client/./0g-storage-client upload \
  --url http://127.0.0.1:8545 \
  --contract "" \
  --key "" \
  --node http://127.0.0.1:5678 \
  --file ./${filename} \
  --tags 0x

# Remove the file
  rm ./${filename}
done

```

Create upload service for your node to run in the background

```
sudo tee /etc/systemd/system/upload.service > /dev/null <<EOF
[Unit]
Description=station track service
After=network-online.target
[Service]
User=root
WorkingDirectory=/root/
ExecStart=sh ./upload.sh
Restart=always
RestartSec=3
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF
```

Start upload

```
sudo systemctl daemon-reload && \
sudo systemctl enable upload && \
sudo systemctl restart upload
```

check log

```
sudo journalctl -u upload -f
```

If you see this result, the test was successful
