This guide will walk you through setting up renterd on Linux. At the end of this guide, you should have the following:
  • Installed Sia renterd software
  • Created a renterd wallet


  • Network Access: renterd interacts with the Sia network, so you need a stable internet connection and open network access to connect to the Sia blockchain.
  • Operating System Compatibility: Ensure your Linux version is compatible with the renterd software. Check releases supported by Linux versions.
  • System Updates: Ensure that your Linux is up to date with the latest system updates, as these updates can contain important security fixes and improvements.
Your machine must meet the minimum requirements for renterd. Not meeting these requirements may result in preventing slabs from uploading and can lead to a loss of data. A stable setup that meets the following specifications is recommended.
  • A Linux distro with systemd (Ubuntu, Debian, Fedora, Arch, etc)
  • A dual-core CPU
  • 16GB of RAM
  • An SSD with at least 128GB of free space.
To be safe, we have set the recommended minimum RAM requirement as 16GB. This is because renterd keeps full slabs in memory when uploading. A full slab is 120MB, and a single upload may hold two or three slabs in memory. So while it is possible to run renterd with 8GB of RAM, you should only do so if you understand the risks.

Getting renterd

Remember to check which version to download to ensure it works correctly with your operating system. To do this, run uname -m in your Terminal Emulator.
  • x86_64 - Linux AMD64
  • aarch64 - Linux ARM64
  1. 1.
    Download the latest version of renterd for your operating system from the official website. For this guide, we'll be downloading the Linux version of renterd. Open the Terminal Emulator and run the following command:
If you are installing renterd on a Raspberry Pi or other ARM64 architecture, or you intend to use the Zen Testnet. Make sure to download the correct binary for your system.
Zen AMD64
  1. 2.
    Now that we have downloaded renterd, we can unzip and extract the renterd binary to our /usr/local/bin directory.
Zen AMD64
Zen ARM64
unzip -j renterd &&\
sudo mv -t /usr/local/bin renterd &&\
rm -fr
unzip -j renterd &&\
sudo mv -t /usr/local/bin renterd &&\
rm -fr
unzip -j renterd &&\
sudo mv -t /usr/local/bin renterd &&\
rm -fr
unzip -j renterd &&\
sudo mv -t /usr/local/bin renterd &&\
rm -fr
You'll be prompted to authorize this action by providing your system password. Type this in and press enter to continue.

Creating a wallet

  1. 1.
    renterd uses BIP-39 12-word recovery phrases. If you already have a 12-word seed, skip this step; run the following command to generate a new wallet recovery phrase:
renterd seed
A new 12-word recovery phrase will be generated, so please copy and store it in a safe place, as you will need this phrase to recover your wallet.
If you lose this phrase, you will lose access to your wallet and funds. Find out more about Your Sia Seed and why it is essential.
Generating a recovery phrase

Setting up a systemd service

Now that you have a recovery phrase, we will create a new system user and systemd service to securely run renterd on startup.
First, we will create a new system user with useradd and disable the creation of a home directory. This is a security precaution that will isolate renterd from any unauthorized access to our system. We will then use usermod to lock the account and prevent anyone from logging in under the account.
sudo useradd -M renterd &&\
sudo usermod -L renterd
Now, we will create a new folder under /var/lib/ titled renterd and give it the appropriate permissions. This folder will be utilized specifically to store data related to the renterd software. Open the Terminal Emulator and run the following commands:
sudo mkdir /var/lib/renterd &&\
sudo chown renterd:renterd /var/lib/renterd &&\
sudo chmod o-rwx /var/lib/renterd
Next, create a file name renterd.yml file under /var/lib/renterd/
sudo nano /var/lib/renterd/renterd.yml
Now, modify the file to add your wallet seed and API password. The recovery phrase is the 12-word phrase you generated in the previous step. Type it carefully, with one space between each word, or copy it from the previous step. The password is used to unlock the renterd UI; it should be something secure and easy to remember.
If you are planning to use renterd's built-in S3 API, make sure you enable S3 in your renterd.yml file.
Basic Config
S3 Enabled
seed: your seed phrase goes here
password: your_password
heartbeat: 5m
seed: your seed phrase goes here
password: your_password
heartbeat: 5m
enabled: true
disableAuth: false
address: "localhost:9885"
your_access_key: your_private_key
Once you have added your recovery phrase and password save the file with ctrl+s and exit with ctrl+x.
Next, we'll create a new system service to run renterd on startup:
sudo nano /etc/systemd/system/renterd.service
Once the editor loads, copy and paste the following into it.
You can now save the file with ctrl+s and exit with ctrl+x.

Running renterd

Now it is time to start the service
sudo systemctl start renterd
Your renterd service should now be running. You can check the status of the service by running the following command:
sudo systemctl status renterd
If the service was set up correctly, it should say "active (running)."
Starting renterd
  1. 3.
    You can now access the renterd web UI by opening a browser and going to http://localhost:9980.
If you are using the Zen Testnet, please note that the renterd web UI is accessible at https://localhost:9880.
renterd Login UI
Enter the API password you created in the previous step to unlock renterd.
Congratulations on successfully setting up renterd and taking a significant step towards renting storage space on the Sia network.
