Join Drew Falkman for an in-depth discussion in this video Testnet/Ropsten and mainnet deployment, part 2, part of Ethereum: Building Blockchain Decentralized Apps (DApps).
- [Instructor] Okay, so now I'm back.…I have now synced up my local testnet…with the Ropsten testnet.…I'm going to be honest with you,…it was not a completely smooth process.…It crashed a couple times.…I got some error messages saying…that it had stopped syncing.…And what I did was I just deleted my chain data directory,…and I resynced it again from scratch.…So it did take a couple tries, but here we are.…It is now just syncing live with the testnet.…Now that I've started Geth,…I can create a new command line tab.…
And from here, I can attach to the Geth server…and run command lines against it.…So what I need to do now is I want to go ahead and attach.…So we say geth attach,…and we then type in http://127.0.0.1:8545,…which is the Go Ethereum port.…So now I'm at the command line.…You can see all those API modules that I set up…when I started Geth are now available to me.…
