Unable to contact Ethereum node
Hi,
I have an issue when I want to deploy my Dapp on the server. This is the procedure that I have done :
Here there is the nodeInfo of my Ethereum node :
Can someone know what is the URL of my node or why Mix can't connect to it ?
Thanks
I have an issue when I want to deploy my Dapp on the server. This is the procedure that I have done :
- In a terminal : geth --port 30301 --rpcport 8545 --dev console
- In Mix Deploy>Deploy to network
- In the field "Ethereum node URL" : I put http://localhost:30301

You should put 8545 for the port.
Also you might need to add the option --rpc also.
Thanks a lot.
May I ask another question.
My account doesn't have any ether, but I want to deploy my Dapps on my private test blockChain. Do you know if I need any ether ? and how can I get some if I don't want to connect myself to the public blockChain ?
I got ether by mining into my private chain.

https://gitter.im/ethereum/mist
.. and so on
Start geth (without parameters).
Geth reports its "listening" on 30301.
I then start Mix and then Deploy>Deploy to Network. The dialog box reports:
"unable to contact Ethereum node on http://localhost:30301"
Tried altering 30301 to 8585, 30303 etc. No success.
When I edit the "ethereum node url" box, the red error report also updates instantly.
Running Mix on MacOSX.
Any pointers gratefully received.
I start geth with the rpc option:
geth -rpc
It starts ok eventually reporting:
.... server.go:552] Listening on [::]:30303
I then start Mix and attempt to deploy contract.
In the "Ethereum node url" box I enter
http://localhost:30303
No matter what I enter, underneath the entry box it reports (in red)
"Unable to connect to Ethereum node ...."
where .... is whatever entered. Interestingly as I edit the entry box
the red error message updates simultaneously. There does not
appear to be any attempt to connect to anything even after pressing the
reset button.
on a Mac OSX computer.
Mix crashes at different points. I cannot reproduce the exact point
at which Mix crashes.
1. Have to restart computer to get a "clean" state
2. Start geth in terminal
geth --rpc --rpcport 8585
3. Wait till geth starts updating blocks
4. Start Mix, point to right contract
5. >Deploy >Deploy to network.
6. In first box ensure it says the 8585 port
7. Maybe have to redo steps 1 - 5
8. Again try and deploy to network hoping port is configured ok.
9. Now can start to deploy by moving to next dialog box
10. Shifting away from this dialog box caused Mix to crash.
11. Restart at 1 etc etc
Most of the time Mix crashes immediately when going to >Deploy.
Sometime not. Sometime I can get to second screen of Deploy.
But when I move away from that screen it always crashes.
Any help much appreciated.
For the record, the setup I use on a Mac OSX is to use in terminal
geth --rpc --rpcport 8585
and then Mix>Deploy is pointing to node 8585.
My moto now is " keep things simple/minimal".
