description: Tutorial on setting up swarm node.

Setting up Swarm

To run swarm you first need to install geth and bzzd which is the swarm daemon.

  1. go install github.com/ethereum/go-ethereum/cmd/geth
  2. go install github.com/ethersphere/swarm/cmd/swarm

Now we’ll generate a new geth account.

  1. $ geth account new
  3. Your new account is locked with a password. Please give a password. Do not forget this password.
  4. Passphrase:
  5. Repeat passphrase:
  6. Address: {970ef9790b54425bea2c02e25cab01e48cf92573}

Export the environment variable BZZKEY mapping to the geth account address we just generated.

  1. export BZZKEY=970ef9790b54425bea2c02e25cab01e48cf92573

And now run swarm with the specified account to be our swarm account. Swarm by default will run on port 8500.

  1. $ swarm --bzzaccount $BZZKEY
  2. Unlocking swarm account 0x970EF9790B54425BEA2C02e25cAb01E48CF92573 [1/3]
  3. Passphrase:
  4. WARN [06-12|13:11:41] Starting Swarm service

Now that we have the swarm daemon set up and running, let’s learn how to upload files to swarm in the next section.
