Set up an Ethereum development network in two minutes

ethereum-dev-mode.md

First, install the required software:

• Geth: http://geth.ethereum.org/downloads/
• Mist: http://github.com/ethereum/mist/releases

Instructions for Windows

• Open CMD (windows > run > type "cmd" > enter).
• Run geth.exe --dev --ipcpath geth.ipc console
• on the CMD window, type personal.newAccount() to create a password for your default (etherbase) account
• on the CMD window, type miner.start().
• open Mist.

Instructions for Mac

• Open Terminal (Cmd + space > terminal.app)
• Run geth --dev --ipcpath ~/Library/Ethereum/geth.ipc console
• on the Terminal, type personal.newAccount() to create a password for your default (etherbase) account
• on the Terminal, type miner.start().
• open Mist

Instructions for Linux

• Open your terminal of choice
• Run geth --dev --ipcpath ~/.ethereum/geth.ipc console
• on your terminal, type personal.newAccount() to create a password for your default (etherbase) account
• on your terminal, type miner.start().
• open Mist

That's it. You can use miner.start() and miner.stop() to control wether you computer will be generating blocks and validating your own transactions.

Troubleshooting

Mist started on the test-net

On Mist, change the network to Main Net (Develop > Network > Main net), terminate both Mist and Geth, and restart them.

Throw some feedback in the comments :)

This has nothing to do with a private network. This is about a connection to the public dev network. To start a private network you need to init your one network with a genisis file. And specify your own data dir in the geth command.

--dev creates a private network. From geth --help:

  --dev              Developer mode: pre-configured private network with several debugging flags

Thank you for all your valuable guidance and support. The instructions above worked a treat. The only deviation was step 3 on the Mac, which required me to open another Terminal window and attach geth to my ipc instance, before running the personal.newAccount and miner.start() commands.

I create private network and our group start miner.

Now I want to connect with Mist.

please advice me ...

Please, make a manual step by step for windows 10, install from scratch, create repositories, connect with web3, create JSON, the other solution to make the fog automatically create all this and even give the option of mining in the menu of minst, this would help more wallets to be open and a worldwide distribution, I am supporting ETH for adoption in my real projects on alimentae and start accepting ETH in the real world, but most of the world uses windows and it is necessary to make a complete manual to create other software to be complemented in our collection teams. #evertonfraga @evertonfraga

Hi, the --dev flag and the private network are two concepts that I'm trying to understand. Could you please help me with the following.

I've installed geth in a Raspberry Pi 3. I want to make two nodes (accounts) in the same RPi interact in a private ethereum network. If I start both nodes without the --dev flag I've managed to connect them. However since my hardware is limited (1GB ram) I always get the "out of memory error" if i try to mine without the --dev flag. So for this reason i use the flag but when i do so I cant make both nodes to see each other. Is it because what I'm trying to do and the flag are mutually exclusive or am I missing some configuration?

I can tell that I am initializing both nodes with the same genesis file. I've been careful with the enode and port numbers. So I'm lost as to whats happening.

Thanks in advance.

May I contact Mist support? Does anyone have this contact?
