[Ethereum] connect Mist to geth running in private testnet

go-ethereummisttestnets

I'm trying to run a private ethereum testnet for myself. I have installed geth 1.6.7 from the official Ubuntu PPA, and downloaded the latest Mist release from its github repo.

I've run

geth --datadir="~/mydir" init my-gen.json
geth --datadir="~/mydir" --networkid 15 --rpc console

then, on another terminal:

mist --rpc "/mydir" --mode geth --gethpath "/usr/bin/geth"

but mist doesn't connect to the running geth console (I've also tried running geth without the console). it doesn't even find geth, so it tries to download it.

basically all the posts/issues I read were solved by adjusting the rpc/ipc path, but mine seems to be correct, as per geth's output:

IPC endpoint opened: /mydir/geth.ipc

Mist's log (excerpt):

[INFO] ClientBinaryManager - Initializing...
[INFO] ClientBinaryManager - Resolving path to Eth client binary ...
[INFO] ClientBinaryManager - Eth client binary path: /opt/Mist/nodes/eth/linux-x64/eth

[INFO] ClientBinaryManager - Verifying status of all 1 possible clients...
[INFO] ClientBinaryManager - Verify Geth status ...
[ERROR] ClientBinaryManager - Unable to resolve Geth executable: usr/bin/geth

how can I have Mist recognize the running geth instance?

Try this:

geth --ipcpath eth-test-chain/geth.ipc --datadir eth-test-chain --networkid 15

it worked for me. I guess the --rpc option is interfering with the IPC interface.

Or if you need to get access to console, from another terminal issue:

geth --ipcpath eth-test-chain/geth.ipc --datadir eth-test-chain --networkid 15 console

Move your ~/.ethereum wallet to a different location (if you already have one so as not to mess up your live stuff), take off the --datadir on your geth line, re-run everything, and it should work. ~/.ethereum is hard coded in Mist. (for now?)

https://github.com/ethereum/mist/blob/v0.3.8/modules/ipc/getIpcPath.js

module.exports = function() {
    var p = require('path');
    var path = global.path.HOME;

    if(process.platform === 'darwin')
        path += '/Library/Ethereum/geth.ipc';

    if(process.platform === 'freebsd' ||
       process.platform === 'linux' ||
       process.platform === 'sunos')
        path += '/.ethereum/geth.ipc';

    if(process.platform === 'win32')
        path = '\\\\.\\pipe\\geth.ipc';

    console.log('CONNECT to IPC PATH: '+ path);
    return path;
};

Alternatively, you can have just have the .ipc file in the right place that Mist is looking for it (specify an IPC file in the ~/.ethereum directory from geth and a datadir some other place), but to me this seems more complicated.

[Ethereum] Launch Mist directly on Testnet

You can run Mist and geth on the testnet, but the testnet contains around 1 700 000 blocks againt 2 300 000 for the mainnet. So it will take time. To run geth on the testnet, you just need to execute geth --testnet To run Mist on the testnet, just select Develop / Network / Testnet

Otherwise, if you just want to quickly develop a contract and create a dapp (meteor or not), I advice you to try testrpc and truffle.

- testrpc allows to create a testing ethereum private blockchain

Installation : npm install -g ethereumjs-testrpc

Start : testrpc

More info: https://github.com/ethereumjs/testrpc

- truffle is a framework which will help you to create, test and deploy a contract and also to build a dapp (web3 bootstrap for your contracts) :

Installatiion: npm install -g truffle

Setup:

truffle init to create a project

truffle compile to compile your contracts

truffle migrate to deploy your contract on your private test blockchain, or on the testnet or on the libe network

truffle serve to run your web dapp (nodejs)

More info: https://github.com/ConsenSys/truffle

Hope this help.
