this method… occur error…

—error message–
The Compose file ‘./Server/docker-compose.yaml’ is invalid because:
services.validator.extra_hosts contains an invalid type, it should be an object, or an array

Use Docker 20.10 or higher

If you can’t, find a way to replace the “extra_hosts” option in the “docker-compose.yaml” file.

Try the following.

  1. Remove “extra_hosts” option from “docker-compose.yaml” file
  2. Manually set the IP address to replace the “host.docker.internal” value in the “__init__.py” file. (172.17.0.1)

Thanks for sharing. I’ve passed this on to the dev team to take a look at.

It’s very impressive.
Thanks for sharing your own solution.

Do you mind if I ask

  • CPU and Motherboard Spec?
  • Daily mining rate?

I tried it on Ubuntu 20.04.

There were two problems.

  1. The double quotation marks seem to be missing.
    extra_hosts:
    • “host.docker.internal:host-gateway”

You need to modify it as above for it to work properly.

  1. On Ubuntu 20.04

/usr/bin/g+±7 -O2 -Wall ./*.cpp -o ./hashServer -lboost_system -lpthread -lcryptopp

The above command doesn’t work.

Just replace g+±7 with g+±9.

But it doesn’t use multicore.

How can I get it to work properly on Ubuntu 20.04?

  1. Fixed “extra_hosts” issue.

  2. Try running it with the “start_creditcoin.sh” script.
    And check if the “hashServer” process is running.

  3. When you need to stop mining, use the “-s” option in the “start_creditcoin.sh” script.

  4. The “environment variable” below is required.
    export CREDITCOIN_HOME=/root/Server
    Check the configure_creditcoin.sh script.

Check the changed history
start_creditcoin.sh

export CREDITCOIN_HOME=~/CreditcoinDockerCompose-Mainnet/Server

First, I set the HOME folder as above.

./start_creditcoin.sh

When I run the above command

CREDITCOIN_HOME is /root/CreditcoinDockerCompose-Mainnet/Server
No processing specification found for this machine. Ensure script sha256_speed_test.sh is scheduled in crontab.

The above came out.

And How do I run the hashServer process?

How can I run the server?

Check the install_apt_packages.sh script.

Check the sha256_speed_test.sh script.

If the environment is complex, write a script that runs only hashServer and use it.

  hashServerPid=$(head -n 1 $CREDITCOIN_HOME/hashServer.pid 2> /dev/null)
  kill $hashServerPid 2> /dev/null
  rm $CREDITCOIN_HOME/hashServer.pid 2> /dev/null
  sudo $DOCKER_COMPOSE -f $docker_compose down 2>/dev/null
  sudo docker network prune -f
  nohup $CREDITCOIN_HOME/hashServer 10000 >> $CREDITCOIN_HOME/hashServer.log &
  hashServerPid=$!
  echo $hashServerPid > $CREDITCOIN_HOME/hashServer.pid
  renice -n 10 -p $hashServerPid
  sudo $DOCKER_COMPOSE -f $docker_compose up -d
  hashServerPid=$(head -n 1 ~/CreditcoinDockerCompose-Mainnet/Server/hashServer.pid 2> /dev/null)
  kill $hashServerPid 2> /dev/null
  rm ~/CreditcoinDockerCompose-Mainnet/Server/hashServer.pid 2> /dev/null
  sudo docker-compose -f ~/CreditcoinDockerCompose-Mainnet/Server/docker-compose.yaml down 2>/dev/null
  sudo docker network prune -f
  nohup ~/CreditcoinDockerCompose-Mainnet/Server/hashServer 10000 >> ~/CreditcoinDockerCompose-Mainnet/Server/hashServer.log &
  hashServerPid=$!
  echo $hashServerPid > ~/CreditcoinDockerCompose-Mainnet/Server/hashServer.pid
  renice -n 10 -p $hashServerPid
  sudo docker-compose -f ~/CreditcoinDockerCompose-Mainnet/Server/docker-compose.yaml up -d

CPU Usage is great. But

2021-08-12 00:37:19 Open file descriptors: 163
Number of open Validator peers is 0.  Restart Creditcoin node? (y/n)

There are no open Validator peers.

I’ve been watching for the past hour but no connection with peers.

How can I solve this problem?

The peer problem seems to be a different problem from my environment.

Could it be a problem with the basic settings?

Did you check if port 8800 is open?

Yes.

Connection is fine without multicore script.

Could please tell me how to install this script?

I think it is different from the official installation method.

This is a script written by Gluwa.
There was no official manual.

This is a useful script, but
No problem even if you don’t use it.

Great. It works. thx.

Can I change the number of threads? Currently, all threads except one are used in all threads. As a result, the CPU overload is high. What if I want to use only 12 out of 24 threads?

thanks.
It’s hard time to solo miners :(.
