SUI is a layer 1 blockchain designed by Mysten Labs from the ground up in smart contract specific language called 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.Sui Full Node- Build from source1. Start Up -initialize deviceUpdate your systemsudo 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 statussudo ufw status Good idea to check if you can still remote into server at this point before continuing2. install prerequisite software for SuiWe need a lot of dependencies in order to run SUI Install the following packagessudo 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 installationcargo --version rustc --version Download Rust and Cargo from scriptcurl --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 $HOME/.cargo/env rustup update stable Should you need to uninstallrustup self uninstall 3. install form Sui from Gitwe will first fork the repository to our own account, you need to log into your github.com account and fork fromGitHub - MystenLabs/sui: Sui, a next-generation smart contract platform with high throughput, low latency, and an asset-oriented programming model powered by the Move programming languageSui, a next-generation smart contract platform with high throughput, low latency, and an asset-oriented programming model powered by the Move programming language - MystenLabs/suihttps://github.comback to the terminal of your device, clone the forked repositorygit clone https://github.com/<YOUR-GITHUB-USERNAME>/sui.git change to our working directorycd sui Set up the Sui repository as a git remotegit remote add upstream https://github.com/MystenLabs/sui Sync your forkgit fetch upstream check out the devnet branchgit checkout --track upstream/devnet make copy of the fullnode configuration template:cp crates/sui-config/data/fullnode-template.yaml fullnode.yaml Download the latest genesis state for Devnet by clicking that link or by running the following in your terminalcurl -fLJO https://github.com/MystenLabs/sui-genesis/raw/main/devnet/genesis.blob Optional - Specify working paths skip for now4. Create a System service to Run SuiCreate A Service We will create a system service to run SUI in the background as a continuous process allowing the node to remain activesudo tee <<EOF >/dev/null /etc/systemd/system/sui-node.service [Unit] Description=Sui node After=network-online.target [Service] User=$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 nodesudo systemctl enable sui-node sudo systemctl daemon-reload sudo systemctl start sui-node To check the status of the servicesudo systemctl status sui-node To output the logsjournalctl -u sui-node.service -f Our full node will be running in the background and should look something like thisFind your Node check that your node is reachable externally and can be reached by other peers, community member build this tool to check onSUI NODETESTERSui Node Tester With Love From Andrew | zValidhttps://node.sui.zvalid.comto 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 soOther Useful CommandsMaking changes to the Node Stop the Node servicesudo systemctl stop sui-node you can confirm its stopped withsudo 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 thoughcd sui open the config, and edit in the terminal, ctrl+o to write the changes and ctrl+x to exit back to the terminalnano fullnode.yaml Restart the servicesudo systemctl daemon-reload sudo systemctl restart sui-node Updating Sui Full Node- for Re-Genesisto 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 for devnet updates. Stop the nodesudo systemctl stop sui-node Move to working directorycd sui Remove the old on-disk database and 'genesis.blob' filerm -r suidb genesis.blob Fetch the source from the latest releasegit fetch upstream Reset branchgit checkout -B devnet --track upstream/devnet Download the latest genesis state for Devnetcurl -fLJO https://github.com/MystenLabs/sui-genesis/raw/main/devnet/genesis.blob Restart your nodesudo 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 so we need to make changes to the .yml to ’find your node’, follow the sections for making changes and ‘find your node’Sui WalletSui 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 for testing, so we can experiment with SUI features on devnet. Download the Chrome extension from the storeSlush - A Sui wallet - Chrome Web StoreYour Sui super apphttps://chromewebstore.google.comCreate a new account, click on the application > get started > create new accountAgree to the terms of service and click ‘Create’Here you will be prompted with a Seed Phrase, which is the only way to recover your account. Save this and find your wallet address here.Request Tokens These are testnet tokens with no value but you can experiment and get involved early to get familiar with SUI before mainnet release Now head over to the SUI discord, facet channel to request testnet tokens to your wallet like soThere’s a few features within the wallet we can test out, such as minting an NFTFound on the top right of the extension, click to expandFull Node with Docker compose– (pending)Sui Validator Node- (pending)
