Instructions
Hello, I'm new to bitshares and I'd like to learn bitshares from building a private testnet.
But when I tried to build one referring to
-https://github.com/bitshares/bitshares-core/wiki/private-testnet
-https://dev.bitshares.works/en/master/development/testnets/private_testnet.html
it always stuck in 4-1
./witness_node --data-dir=data/my-blocktestnet --genesis-json=my-genesis.json --seed-nodes "[]"
it couldn't run a node

In tutorial , it says

Several messages will go to the console. When you see messages like these:
3501235ms th_a main.cpp:165 main ] Started witness node on a chain with 0 blocks.
3501235ms th_a main.cpp:166 main ] Chain ID is cf307110d029cb882d126bf0488dc4864772f68d9888d86b458d16e6c36aa74b

But my node couldn't figure it out.

• Build Environment

I build it on GCP
Linux instance-12 4.15.0-1032-gcp #34~16.04.1-Ubuntu SMP Wed May 8 13:26:26 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
(4 vCPUs, 15 GB memory)
50GB SSD

• Steps To Reproduce

I reproduced it according to the tutorial about ten times.
I tried running directly in bitshares-core, and make testnet_home in different location and run, but they all failed.
Only 1 time I succeeded in running witness_node in bitshares-core but it couldn't repeat later.

[pmconrad]

I think it can't find the genesis file because it is in a subdirectory. Try

./witness_node --data-dir=data/my-blocktestnet --genesis-json=genesis/my-genesis.json --seed-nodes "[]"

instead.

@cedar-book the documentation seems to be wrong in that detail.

Also, the error message from witness_node is misleading and should be improved.

[abitmore]

Or perhaps the program failed to parse genesis file due to wrong format or so? @heyasjack can you upload your genesis file so we can check?

@abitmore
Thank you for your help!

And the genesis has 2 version. I have tried both of them, but it seemed that both of them have similar problems.
The old one is from https://dev.bitshares.works/en/master/development/testnets/private_testnet_genesis_example.html#private-testnet-genesis-example
And the new one is copied from bitshares-core/libraries/egenesis/genesis-dev.json , which refer to #1591

the old one

@pmconrad Thank you for your help !
I tried your code in testnet_home, but it seemed to have a same problem.
And the genesis.json file have 2 version, I get confused of them.

The old one is from https://dev.bitshares.works/en/master/development/testnets/private_testnet_genesis_example.html#private-testnet-genesis-example
And the new one is copied from bitshares-core/libraries/egenesis/genesis-dev.json , which refer to #1591

I haven't change the genesis.json when I run the witness_node. Should I need to change some variable or chain ID of it?
And I'm going to try both of them using your code in different location now.

[abitmore]

@heyasjack try absolute path, e.g. --genesis-json=/root/bitshares-core/testnet_home/genesis/my-genesis.json?

Please make sure the file is there:

ls -l /root/bitshares-core/testnet_home/genesis/my-genesis.json

The old one with "block_signing_key": "--- set a public key ---" won't work anyway.

[heyasjack]

@abitmore Thank you for your advice!
But I failed again.
I used GCP ubuntu for testing, so maybe I had made something wrong setting.
And if you have some free time, could you make a test on your device according to the tutorial, so we can see whether the document is wrong or I made the wrong setting. https://dev.bitshares.works/en/master/development/testnets/private_testnet.html
I‘m all gratitude!

[heyasjack]

@abitmore @pmconrad Thank you for your help!
Well, I succeed in running the witness_node with
root@instance-7:/home/user1/bitshares-core# programs/witness_node/witness_node --data-d ir data/my-blockprod --genesis-json genesis/my-genesis.json --seed-nodes "[]"
which is from https://github.com/bitshares/bitshares-core/wiki/private-testnet.
I leave genesis file in bitshares-core/genesis/my-genesis.json, and the my-genesis.json is from https://github.com/bitshares/bitshares-core/blob/master/libraries/egenesis/genesis-dev.json
And later I will repeat these steps and check whether it is stable.

[heyasjack]

oh, I failed again. With almost the same steps.

Their difference begin from that.
But I noticed the difference between application.cpp:209 and application.cpp:353 ,but I don't know why and how to solve it...
I will test more and I hope you can give me a hand! Please!

[heyasjack]

Well, I FOUND IT!
So stupid I am, the my-genesis.json have something miss part maybe I missed them in the copy step.

[heyasjack]

Yeeeaaa, I repeat it successfully!

The most important things is the route and location, the tutorial has made misleading about the location, check the location of my-genesis.json when you run witness_node.

And the second point is the my-genesis.json, you should copy command
cp -r libraries/egenesis/genesis-dev.json testnet_home/genesis
and then enter the testnet_home/genesis and mv genesis-dev.json my-genesis.json
it often miss the first line of the file, check it first.

[heyasjack]

Oh, I suggest that the tutorial should be added using screen when running the witness_node and cli_wallet
