# SUI Network - complete guide to run a Node & Validator By [GLCstaked](https://paragraph.com/@glcstaked) · 2022-08-03 --- [SUI](https://sui.io) is a layer 1 blockchain designed by [Mysten Labs](https://mystenlabs.com/) from the ground up in smart contract specific language called [MOVE](https://docs.sui.io/build/move) This guide will go over installing a Full Node and Validator from scratch in order to run a Sui network node, assumes a fresh install of Ubuntu 20.04LTS. **Hardware Requirements**: Node Requirements: Full node requirements are lower, but storage can be expected to increase over time CPUs: 2 RAM: 8GB Storage: 50GB Validator Requirements: Validators perform work and deal with chain consensus, requirements are much higher. ![](https://storage.googleapis.com/papyrus_images/932852a329a334e4652991bde0018db618cdeabe930c7feff43f898593e2a115.png) Sui Full Node- Build from source -------------------------------- ### 1.     Start Up -initialize device Update your system sudo apt update && sudo apt upgrade -y **Firewall Settings** We will enable ports 8080 & 9000, don’t forget to enable your SSH port if you also require remote access. sudo ufw allow 8080/tcp sudo ufw allow 9000/tcp sudo ufw allow 9184/tcp sudo ufw allow 22/tcp # sudo ufw allow ssh sudo ufw enable Check status sudo ufw status   Good idea to check if you can still remote into server at this point before continuing ### 2\. install prerequisite software for Sui We need a lot of dependencies in order to run SUI **Install the following packages** sudo apt-get update \ && DEBIAN_FRONTEND=noninteractive TZ=Etc/UTC sudo apt-get install -y --no-install-recommends \ tzdata \ git \ ca-certificates \ curl \ build-essential \ libssl-dev \ pkg-config \ libclang-dev \ cmake **Install Rust** We will be using the latest version of the Cargo toolchain to build and manage the dependencies. You will need Cargo to build and install Sui on your machine. check for current installation cargo --version rustc --version Download Rust and Cargo from script curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh you will be prompted with options, select 1 for default installation run, to include  `PATH` environment variable to include Cargo's bin directory `($HOME/.cargo/bin).` source $HOME/.cargo/env rustup update stable Should you need to uninstall rustup self uninstall ### 3\. install form Sui from Git we will first fork the repository to our own account, you need to log into your `github.com` account and fork from [ GitHub - MystenLabs/sui: Sui, a next-generation smart contract platform with high throughput, low latency, and an asset-oriented programming model powered by the Move programming language ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Sui, a next-generation smart contract platform with high throughput, low latency, and an asset-oriented programming model powered by the Move programming language - MystenLabs/sui https://github.com ![](https://storage.googleapis.com/papyrus_images/26ad9bb5ddf0f26eecaf07840481b8886414769dfc9ab069d66b426720ef9367.png) ](https://github.com/MystenLabs/sui) back to the terminal of your device, clone the forked repository git clone https://github.com//sui.git change to our working directory cd sui Set up the Sui repository as a git remote git remote add upstream https://github.com/MystenLabs/sui Sync your fork git fetch upstream check out the devnet branch git checkout --track upstream/devnet make copy of the [fullnode configuration template](https://github.com/MystenLabs/sui/blob/main/crates/sui-config/data/fullnode-template.yaml): cp crates/sui-config/data/fullnode-template.yaml fullnode.yaml Download the latest `genesis` state for Devnet by clicking that link or by running the following in your terminal curl -fLJO https://github.com/MystenLabs/sui-genesis/raw/main/devnet/genesis.blob **Optional - Specify working paths** skip for now ### 4\. Create a System service to Run Sui **Create A Service** We will create a system service to run SUI in the background as a continuous process allowing the node to remain active sudo tee </dev/null /etc/systemd/system/sui-node.service [Unit] Description=Sui node After=network-online.target [Service] User=$USER WorkingDirectory=/$HOME/sui ExecStart=/$HOME/.cargo/bin/cargo run --release --bin sui-node -- --config-path /$HOME/sui/fullnode.yaml Restart=on-failure RestartSec=3 LimitNOFILE=65535 [Install] WantedBy=multi-user.target EOF Enable and Start our Service- this will start our node sudo systemctl enable sui-node sudo systemctl daemon-reload sudo systemctl start sui-node To check the status of the service sudo systemctl status sui-node To output the logs journalctl -u sui-node.service -f Our full node will be running in the background and should look something like this ![](https://storage.googleapis.com/papyrus_images/ec7d679b58a922a9ffe13599fe378284bcfc9f09bbec8dab98f4411df9dddca9.png) **Find your Node** check that your node is reachable externally and can be reached by other peers, community member build this tool to check on [ SUI NODETESTER -------------- Sui Node Tester With Love From Andrew | zValid https://node.sui.zvalid.com ](https://node.sui.zvalid.com/) to do this you may need to change the default settings in your `fullnode.yaml` config, follow the steps under ‘making changes to the node’ to do this. We need to make sure the `metrics-address` and `json-rpc-address` in the `fullnode.yaml` is 0.0.0.0 (it was 127.0.0.1 for me) like so ![](https://storage.googleapis.com/papyrus_images/fdf8d07e5f9f74ed6ce228f8e0c0e8e2389e252edcabb31f6a99f4977848b1ce.png) ### Other Useful Commands **Making changes to the Node** Stop the Node service sudo systemctl stop sui-node you can confirm its stopped with sudo systemctl status sui-node Locate and open the config file, you can find this with `ls -la`, and exploring the folders, it should be here by default though cd sui open the config, and edit in the terminal, `ctrl+o` to write the changes and `ctrl+x` to exit back to the terminal nano fullnode.yaml Restart the service sudo systemctl daemon-reload sudo systemctl restart sui-node Updating Sui Full Node- for Re-Genesis -------------------------------------- to upgrade Sui full node, follow this process. NOTE: this is for a re-genesis upgrade which requires a clean db and full restart. Keep and eye on [SUI discord](https://sui.io/#community) for devnet updates. **Stop the node** sudo systemctl stop sui-node **Move to working directory** cd sui **Remove the old on-disk database and 'genesis.blob' file** rm -r suidb genesis.blob **Fetch the source from the latest release** git fetch upstream **Reset branch** git checkout -B devnet --track upstream/devnet **Download the latest genesis state for Devnet** curl -fLJO https://github.com/MystenLabs/sui-genesis/raw/main/devnet/genesis.blob **Restart your node** sudo systemctl daemon-reload sudo systemctl restart sui-node this will take a while to compile all the packages and start to sync again, NOTE: your full node will once again be running at: [http://127.0.0.1:9000](http://127.0.0.1:9000) so we need to make changes to the .yml to ’find your node’, follow the sections for making changes and ‘find your node’ Sui Wallet ---------- Sui Wallet is an open-sourced wallet for SUI network, allowing users the ability to create an address, view and manage assets on the Sui network, and interact with dApps. This is now available on [Devnet](https://sui.io/resources-sui/introducing-sui-wallet/?utm_source=twitter&utm_medium=social&utm_campaign=twwallet) for testing, so we can experiment with SUI features on devnet.
