Not able to use geth attach

Question

I started Ethereum Blockchain using this command:

geth --datadir ./myDataDir --networkid 1114geth --datadir ./myDataDir --networkid 1114

and then from a different terminal, I am trying to connect to this using the following command:

geth attach http://127.0.0.1:8543

But I am not able to attach geth. I am getting the following error:

Fatal: Failed to start the JavaScript console: api modules: Post http://127.0.0.1:8543: dial tcp 127.0.0.1:8543: connect: connection refused

Answer 1

You are getting this error because you have not specified a port and address for geth process to connect. Due to this, when you are using geth attach, get is not able to find the address and port mentioned in the command. To solve this error, you have mention the address and port while starting the Blockchain. Like this:

geth --datadir ./myDataDir --networkid 1114 console 2 --rpc --rpcport 8543 --rpcaddr 127.0.0.1
