Install your RPC node

Network details​

Here are the coordinates to the Arthera Mainnet

Running a RPC node​

1. Get a Linux machine that meets the requirements​

2. Install Docker​

See the Docker Installation Guide

3. Pull the latest Arthera node image​

docker pull arthera/arthera-node:1.2.1-rc.3

4. Create a folder to hold your Arthera node data​

mkdir $HOME/arthera

5. Generate your node key​

Run the command below to generate your unique node key:

docker run -it -v $HOME/arthera:/data arthera/arthera-node:1.2.1-rc.3 p2p genkey /data/node.key

Check to see if the key was generated successfully by running:

docker run -it -v $HOME/arthera:/data arthera/arthera-node:1.2.1-rc.3 p2p enodeurl /data/node.key

You should see an output similar to the one below:

enode://f2927b8b1bc1b05997acf60f713cda3c776300cdac52b80d8dbfb2b434ef0e7283f8d3ca891d832bab3927b03c52593e575d48d9916804af5bf66a75b5b1288a@127.0.0.1:6534

The output above is your node's enode URL.

6. Download the latest Mainnet genesis file​

Run the command below to download the mainnet.g genesis file:

curl -o $HOME/arthera/mainnet.g https://s3.eu-central-1.amazonaws.com/release.arthera-net/epoch7785.g

7. Test your node​

Replace the following variables and run the command below to start your node:

  • YOUR_PUBLIC_IP with your actual Public IP address.
docker pull arthera/arthera-node:1.2.1-rc.3
docker run --name arthera-rpc --network host -v $HOME/arthera:/data arthera/arthera-node:1.2.1-rc.3 \
  --port 6533 \
  --genesis /data/mainnet.g --genesis.allowUnknown \
  --syncmode full \
  --nodekey /data/node.key \
  --verbosity 4 \
  --cache 4000 \
  --nat extip:YOUR_PUBLIC_IP

Check the output to have the following info:

If you get messages like New block it means your node is syncing and working properly.

You can now stop the node with Ctrl+C, clean the output folder with rm -rf $HOME/arthera/arthera-node $HOME/arthera/chaindata and remove the docker container with docker container rm arthera-rpc and move to the next step.

8. Run your node​

Replace the following variables and run the command below to start your node:

  • YOUR_PUBLIC_IP with your actual Public IP address.
docker container rm arthera-rpc # remove any existing containers just to be sure
docker pull arthera/arthera-node:1.2.1-rc.3
docker run -d --restart unless-stopped --name arthera-rpc --network host -v $HOME/arthera:/data arthera/arthera-node:1.2.1-rc.3 \
  --port 6533 \
  --genesis /data/mainnet.g --genesis.allowUnknown \
  --syncmode full \
  --gcmode full \
  --nodekey /data/node.key \
  --metrics --metrics.addr 127.0.0.1 \
  --verbosity 3 \
  --cache 4000 \
  --nat extip:YOUR_PUBLIC_IP

Check the node was started with docker ps:

CONTAINER ID   IMAGE                                   COMMAND                  CREATED         STATUS        PORTS     NAMES
d6ac0f5fdf14   arthera/arthera-node:1.2.1-rc.3  "arthera-node --data…"   2 seconds ago   Up 1 second             arthera-rpc

and check the logs of the container with docker logs -f arthera-rpc. You should see the following output:

INFO [08-12|05:57:39.972] New block                                ....
INFO [08-12|05:57:39.972] New block                                ....

INFO [08-12|05:57:39.973] New block                                ....

Troubleshooting​

1. Node is not syncing​

The most common problems are firewalls and incorrectly provided external IP address.

2. Cleanup node data and restart node​

  1. Stop the doocker container with docker container stop arthera-rpc
  2. Remove the database with rm -rf $HOME/arthera/arthera-node $HOME/arthera/chaindata
  3. Start the docker container with docker container start arthera-rpc

3. Database is corrupted​
