Running A Sui FullNode

Sui Wizard makes life easy for setting up a fullnode for mainnet, testnet or devnet.

You can follow the doc or check out the medium blog.

​

System Requirements

As per the Sui documentation, the recommended minimum hardware requirements are as follows:

• CPUs: 8 physical cores / 16 vCPUs
• RAM: 128 GB
• Storage (SSD): 2 TB NVMe drive

​

Steps to Setup a Fullnode

​

Step 1: Connect to the Server

To connect to your server, use SSH or RDP to access the server terminal, allowing you to run commands directly.

​

Step 2: Download and Run Sui Wizard

• Download the script

  curl --fail --location --output helper.sh https://raw.githubusercontent.com/Scale3-Labs/sui-node-helper/master/helper.sh
  

• Give executable permissions

  chmod +x helper.sh
  

• Run the script

  If the script prompts to install dependencies, type ‘y’ to install them.

  ./helper.sh
  

​

Step 3: Configure the server for running Sui Mainnet Fullnode

• Once you are on the welcome screen, follow the screenshots below for the steps. Press Yes

• Read the instructions and press Yes to continue.

• Since we are setting up a Fullnode, we will select the RPC Full Node option.

• Select Setup Fullnode From Scratch

• For the next screen, you are asked to choose Sui network, we will choose Mainnet.

• On the next page there are two fields, you can keep it default.

1. Release Version or hash

   This is the sui-node version that has to be installed. The values can be either:

   • Github release: sui-v1.0.0, testnet-1.0.0

   • Branch: mainnet, testnet, or devnet

   • Commit Hash: ae1212baf8f0837e25926d941db3d26a61c1bea2, c525ba6489261ff6db65e87bf9a3fdda0a6c7be3

   Avoid using commit hash as much as possible, using Github Release is the easiest and recommended option.

2. Absolute folder for configs

   Path to the folder where you want to store all your Sui node configs. Configs include fullnode.yaml, binaries, etc.

   Make sure to remember this path for updating your node in future.

   

   After pressing OK or hitting enter/return, the download of the Sui binary will start, and once it’s successfully downloaded, the binary version will be displayed.

   Press OK to proceed to setup “systemd” service.

• You will now be asked to enter a path for storing data. If you’re unsure about the appropriate value, it’s recommended to keep the default setting.

  The folder path should be directed to a disk with ample free space for storing the Sui Blockchain data.

  

• The last step is to start the Sui fullnode process, press Yes if you wish to start or No if you want to make some changes and manually start.

• Once you start/restart your sui-node service, you can check the logs by running the following command:

  journalctl -fu sui-node
