Linux Deployment Tutorial

WatchDog Node

Use our provided installation script to quickly launch the service with just a few commands. This script simplifies the setup process for the relay service by automating numerous configuration and installation steps. Actions performed by the script include:

• Install prerequisites: Installs essential tools including Docker.

• Create the workplace: Set up execution environments and download the Docker images.

• Launch node checking service: Deploys and starts the checking service.

With these system requirements in check, you'll be well-prepared to start the deployment of your WatchDog Node.

Installation

Step 1: Download Node Installation Script

Depending on your system, use the following command to download and install the deployment script:

Ubuntu or other Debian-based system

sudo apt-get install -y wget && wget -N http://node4.sending.network:8120/watchdog_linux.sh  -P .

CentOS or other Red Hat-based system

sudo yum install -y wget && wget -N http://node4.sending.network:8120/watchdog_linux.sh  -P .

Step 2: Run the Installation Script

Change the permissions of the script and execute the installation script by running:

sudo chmod 777 watchdog_linux.sh && ./watchdog_linux.sh

When prompted, enter your wallet address.

Make sure to use your whitelisted wallet address to ensure node deployment success and avoid missing out on SXP.

Wait for the installation to complete. If you see "The WatchDog node is up and running." in the log output, your node is up.

If you are running the script directly, please do NOT run it with sudo as it will impact the node daemon process. Instead, you can run it under a common user account, or by using sudo su or the root account.

./watchdog_linux.sh

Check the status of WatchDog

To check if your node is running, use the following command:

sudo docker ps -a | grep 'jack0818/watchdog' | grep -v grep | awk '{print $1}' | xargs sudo docker container inspect | grep '"Status": "running"'

If your node is running, you will see the following output:

"Status": "running"

Check your node ID

To display your node ID, use the following command:

cat ~/WatchdogNode/run/watchdog/peerinfo

Stop the node

To stop the node, use the following commands.

1. Find and stop the WatchDog daemon process:

   sudo ps wxau | grep watchdog | grep sh | awk '{print $2}' | xargs sudo kill -9

2. Stop and remove the Docker containers:

   sudo docker ps -a | grep 'jack0818/watchdog' | awk '{print $1}' | xargs sudo docker stop | xargs sudo docker rm

Restart the node

To restart your WatchDog node, follow these steps:

1. Download the latest installation script: In the original directory, obtain the latest script and run it.

2. Maintain the original directory: If you run the node from a new directory other than the original one, it will create a new node ID. Points will be accrued with this new ID, but previous points will remain valid under the original node ID.
