Introduction

In this section, we cover how to install Mycelium. This guide can be done on a local machine and also on a full VM running on the TFGrid.

Currently, Linux, macOS and Windows are supported. On Windows, you must have wintun.dll in the same directory you are executing the binary from.

Considerations

You might need to run Mycelium as root, enable IPv6 at the OS level and disconnect your VPN.

Read the Troubleshooting section for more information.

Set Mycelium

• Update the system

  apt update
  

• Download the latest Mycelium release: https://github.com/threefoldtech/mycelium/releases/latest

  wget https://github.com/threefoldtech/mycelium/releases/download/v0.4.0/mycelium-x86_64-unknown-linux-musl.tar.gz
  

• Extract Mycelium

  tar -xvf mycelium-x86_64-unknown-linux-musl.tar.gz
  

• Move Mycelium to your path

  mv mycelium /usr/local/bin
  

Start Mycelium

You can start Mycelium

• Start Mycelium

  mycelium --peers tcp://83.231.240.31:9651 quic://185.206.122.71:9651 --tun-name utun2
  

• Open another terminal
• Check the Mycelium connection information (address and public key)

  mycelium inspect --json
  

Use Mycelium

Once you've set Mycelium, you can use it to ping other addresses and also to connect into VMs running on the TFGrid.

• Ping the VM from another machine with IPv6

  ping6 mycelium_address
  

• SSH into a VM running on the TFGrid

  ssh root@vm_mycelium_address
  

Mycelium Service (optional)

You can create a systemd service to make sure Mycelium is always enabled and running.

• Create a Mycelium service

  nano /etc/systemd/system/mycelium.service
  

• Set the service and save the file

• Enable the service

  systemctl daemon-reload
  systemctl enable mycelium
  systemctl start mycelium
  

• Verify that the Mycelium service is properly running

  systemctl status mycelium
  

Systemd will start up the Mycelium, restart it if it ever crashes, and start it up automatically after any reboots.
