Launch more than one node connected to Rinkeby from the same machine (change the port doesnt work)

Question

I would like to know if it is possible to launch more than one node connected to Rinkeby from the same machine through Geth and Mist.

In a local testnet, it is possible to do it changing the --port and --rpcport, but I am trying the same connecting to Rinkeby and I get the following error:

    Database closed                 
    Fatal: Error starting protocol stack: Access is denied.

I can launch another geth instance just if I disable the ipc-rpc (--icpdisable), but it is not the right solution since it is not possible to deploy Mist.

You could try using docker. There are lots of network configuration options with docker (it is can be a bit confusing often getting all this right actually).

Try run the following two commands. They bind the ethereum nodes to different ports.

docker run --name ethereum-one \
           -p 8545:8545 -p 30303:30303 \
           ethereum/client-go --rinkeby



docker run --name ethereum-two \
           -p 8546:8545 -p 30304:30303 \
           ethereum/client-go --rinkeby

https://hub.docker.com/r/ethereum/client-go/ <- is the reference. I'm sorry I can't give more details, but I know it is possible with docker. Good luck.

(I hope this works for you)
