Answer 1

IPFS daemon exposes by default three services on three different ports:

• 4001 peer2p which allows to join the network
• 5001 API server serving the full API (see documentation)
• 8080 Gateway server exposing a read only (like http://localhost:8080/ipfs/QmaG4FuMqEBnQNn3C8XJ5bpW8kLs7zq2ZXgHptJHbKDDVx)

The exception Error: serveHTTPGateway: manet.Listen(/ip4/127.0.0.1/tcp/8080) failed: listen tcp4 127.0.0.1:8080: bind: address already in use means that IPFS daemon can't start the gateway because you already have something running on this port.

To find what program runs on the port 8080 an stop it, you can execute the following command:

$ netstat -a | grep 8080 

Answer 2

If you cant stop the program running on port 8080 or you dont want to stop, then go in your home directory, then in .ipfs folder and change the port number in config file.
