How to Run a Nexa Node on a VPS? Running a Nexa node on a VPS is a straightforward process. Follow these steps to get your node up and running quickly: 1. Get a VPS Choose a VPS provider like DigitalOcean, AWS, or Linode. Set up your VPS and get your IP address. - **Resource Requirements:** Make sure your VPS has enough power. The storage will grow as the blockchain gets bigger. - **Operating System:** Use a Unix-like OS such as Ubuntu, Debian, or CentOS. These are reliable and commonly used for such setups. 1. Connect to Your VPS **SSH Key Authentication:** For better security, use SSH key authentication instead of passwords. Generate an SSH key pair with `ssh-keygen` and add the public key to your VPS. Use SSH to connect to your VPS: > ssh username@your\_vps\_ip 1. Update the System **Regular Updates:** Keep your system updated to get the latest security patches and improvements. You can even set up automatic updates for critical patches. Ensure your system is up to date: > sudo apt update && sudo apt upgrade -y 1. Install Dependencies **Right Versions:** Make sure to install the correct versions of dependencies. Some software needs specific versions to work correctly. Install the necessary tools and libraries: > sudo apt install build-essential libtool autotools-dev automake pkg-config bsdmainutils python3 libevent-dev libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-test-dev libboost-thread-dev libssl-dev libdb-dev libdb+±dev -y 1. Install Nexa Node Download the Nexa node binaries: > wget [https://www.bitcoinunlimited.info/nexa/2.0.0.0/nexa-2.0.0.0-linux64.tar.gz](https://www.bitcoinunlimited.info/nexa/2.0.0.0/nexa-2.0.0.0-linux64.tar.gz) > tar -xzvf nexa-2.0.0.0-linux64.tar.gz > sudo mv bin/\* /usr/local/bin/ Or compile from source: > git clone [https://gitlab.com/nexa/nexa.git](https://gitlab.com/nexa/nexa.git) > cd nexa > ./autogen.sh > ./configure > make > sudo make install 1. Configure the Node - **Configuration Options:** Besides the basic setup, you might need to customize parameters like `maxconnections` (for network connections) and `rpcport` (for remote procedure calls). Keep your RPC credentials strong and secure. - **RPC Security:** Bind the RPC interface to `localhost` unless you need remote access. If you do, make sure it’s well-secured. Create a configuration file: > mkdir -p ~/.nexa > nano ~/.nexa/nexa.conf Add this configuration: rpcuser=yourusername rpcpassword=yourpassword rpcallowip=127.0.0.1 server=1 daemon=1 1. Start the Node - **Initial Sync:** The first time you start the node, it will sync with the blockchain network, which can take a while. - **Log Management:** Regularly check the log files in `~/.nexa/debug.log` for issues. Set up log rotation to prevent logs from growing too large. Start your node: > nexad Check if it’s running: > ./nexa-cli getpeerinfo | grep inbound On gui: > getpeerinfo 1. Set Up Process Management **Systemd Benefits:** Using `systemd` ensures your node restarts automatically if it crashes and starts at boot time. You can customize the `systemd` service file to include specific parameters or environment variables. Use systemd to keep your node running: > sudo nano /etc/systemd/system/nexad.service Add this content: > [Unit] > Description=Nexa Node > After=network.target > > [Service] > ExecStart=/usr/local/bin/nexad > User=yourusername > Group=yourusername > Type=forking > PIDFile=/home/yourusername/.nexa/nexa.pid > Restart=always > PrivateTmp=true > [Install] > WantedBy=multi-user.target Enable and start the service: > sudo systemctl enable nexad > sudo systemctl start nexad > sudo systemctl status nexad 1. Open Firewall Port - **Securing Ports:** Only open the necessary ports. For example, port 7228 for network connections and your chosen RPC port if needed. Close other unnecessary ports to reduce security risks. - **Firewall:** VPS should have no router firewall. Allow the Nexa network port through your firewall: > sudo ufw allow 7228 If you are running Rostrum, also allow its port: > sudo ufw allow 20001 1. Monitor Your Node - **Regular Checks:** Keep an eye on your node with commands like `./nexa-cli getpeerinfo | grep inbound` to monitor its status, including block height and peer connections, gui command is only `getpeerinfo`, then can check the entries for the inbound field. - **Do Not Store Coins:** If you are setting up an open node like this on a VPS, do not use that node to store your coins. Keep an eye on your node: > ./nexa-cli getpeerinfo | grep inbound This guide should help you get your Nexa node up and running smoothly on a VPS. Thank you for your support!
