I want to start rinkeby locally on network .......

When I run geth from command line, it uses datadir folder. While geth is running on I also want to start mist, but it give me error datadir is used by another process.

How I can run both simultaneously

Thanks in Advanced

  • Change geth data dir by specifying --datadir then both will work. – Jitendra Kumar. Balla Feb 14 '18 at 14:12

Although your question is not clear for me, I'll try to provide general steps to connect geth with Mist.

  1. start geth node: geth --datadir="/some/path/to/chaindata_folder" --rpc --rpccorsdomain "*" --rpcapi "eth,web3,personal,net,miner,admin,debug"
  2. start Mist in new Terminal tab / window with specified geth.ipc file (see it geth terminal): open -a /applications/mist.app/contents/macos/mist --args --rpc "/some/path/to/geth.ipc"
  3. attach geth.ipc in new Terminal: geth attach ipc:"/some/path/to/geth.ipc"

/some/path/to/geth.ipc - find in first terminal “IPC endpoint opened:”

  • Thanks, this worked for me..... For mac, first we have to run geth --rinkeby --rpc --rpcapi db,eth,net,web3,personal --cache=2048 --rpcport 8545 --rpcaddr --rpccorsdomain "*" and then run /Applications/Mist.app/Contents/MacOS/Mist --rpc ~/Library/Ethereum/rinkeby/geth.ipc – user23593 Aug 8 '18 at 6:04

I assume you want your mist to use the same datadir as geth.

Try to tell mist to use the geth.ipc file that geth creates, by giving it the --rpc "~/geth.ipc" param when starting it (of course, update that with the actual path to the geth.ipc file).

  • Hi, Thanks for your reply. Can you help me with, how to start mist from MAC terminal with geth.ipc Thanks – user23593 Feb 15 '18 at 5:05
