Common operation and debug steps

Quick start to running ICON2 node

Prerequisites

We recommend running nodes using Docker.

{% hint style="info" %} System Requirements

  • CPU: minimum 4core, recommend 8core +
  • RAM: minimum 16GB, recommend 32GB +
  • DISK : minimum SSD 1.5TB, recommend SSD 2TB +
  • Network: minimum 1Gbps, recommend 2Gbps +

External Communications

  • TCP 7100: TCP port used for peer-to-peer connection between peer nodes.
  • TCP 9000: JSON-RPC or RESTful API port serving application requests.
    P-Rep must allow TCP connections to port 7100 and 9000 of an external host.
    ( Use 0.0.0.0/0 for a source from any network ) {% endhint %}

{% hint style="danger" %} ICON1 node must be maintained until the migration is completed,
ICON2 node must be executed with the new server.

The citizen node operated Exchanges and another citizen node must run nodes after the Stage3 migration is complete.

SejongNet (TestNet) can be reset at any time. {% endhint %}

Default Directory Structure

The default project name is the base directory of the docker-compose.yml file.** **We recommend that you use the ICON2 official image(iconloop/icon2-node). If you want to create your new image, see the next section.

If you have imported or created an image, proceed to the next step.

  1. Create a base directory
  2. Create a config directory and import a Keystore file from ICON1 server.

For example:

  • base directory : /app/icon2-node
  • config directory: /app/icon2-node/config # location of keystore.json file

{% hint style="warning" %} If you are P-Rep, you must use the keystore.json file used in ICON1.

If they use dual Keystore:

  • Fisrt Keystore -> for voting and claim
  • Second Keystore -> for operating goloop node {% endhint %}
$ mkdir /app/icon2-node # make a base directory
$ cd /app/icon2-node
$ mkdir -p /app/icon2-node/config  # make a config directory, 

# Import a keystore file to /app/icon2-node/config/ from ICON1 server

The subdirectories(data, config, icon, logs … ) are created by docker engine, but config directory needs to importing your keystore file.

.

    ├── download.log
    ├── download_error.log # download  
    └── goloop.log   # goloop's log file

Open docker-compose.yml in a text editor and add the following content.

version: '3'
services:
  icon2-node:
    image: 'iconloop/icon2-node'
    restart: "on-failure"
    container_name: "icon2-node"
    network_mode: "host"
    stdin_open: true
    environment:
      SERVICE: "MainNet"  # MainNet, SeJong
      #IS_AUTOGEN_CERT: "true"
      GOLOOP_LOG_LEVEL: "debug" # trace, debug, info, warn, error, fatal, panic
      KEY_STORE_FILENAME: "INPUT_YOUR_KEY_STORE_FILENAME" # e.g. keystore.json read a config/keystore.json
      KEY_PASSWORD: "INPUT_YOUR_KEY_PASSWORD" # e.g. "/goloop/config/keystore.json" read a "config/keystore.json" of host machine
      FASTEST_START: "true"    # It can be restored from latest Snapshot DB.
      ROLE: 3 # preps = 3, citizen = 0

    cap_add:
      - SYS_TIME

    volumes:
      - ./config:/goloop/config
      - ./data:/goloop/data
      - ./logs:/goloop/logs

Enter the following commands: (These commands includes docker pull )

$ docker-compose pull
$ docker-compose up -d

How to check the status of the ICON2 node with logs

The booting.log contains messages about the booting status of the ICON2 node. It includes default configuration variables and Docker environment variable.

How to download ICON2 data (migrated backup data)

{% hint style="info" %} If you use docker, it’s not necessary. It is automatically downloaded in docker image. {% endhint %}

Installing aria2

Download version 1.36.0. There you can download source distribution and binaries for OS X, Windows and Android.

After installation is complete, download the backup data with the command below.

$ curl https://networkinfo.solidwallet.io/info/MainNet.json
{
    "network_name": "MainNet",  <- network name (MainNet, SejongNet)
    "index_url": "http://20.20.6.86:8080/file_list.txt", <- indexed file
    "checksum_url": "http://20.20.6.86:8080/checksum.json",  <- checksum file
    "updated_time": "2021-10-20 19:16:00.942"
}

Download a file_list.txt file

$ aria2c http://20.20.6.86:8080/file_list.txt

Download a checksum.json file

$ aria2c http://20.20.6.86:8080/checksum.json

Download URIs found in file_list.txt

$ aria2c -d data -i file_list.txt -V \
-j20 -x16 --http-accept-gzip --disk-cache=64M \
--allow-overwrite --log-level=error --log download_error.log -c 
  • download_error.log that checks the error log
  • -d data : The data directory to store the downloaded file
  • -i file_list.txt : Downloads the URIs listed in file_list.txt
  • -j 20 : Set the maximum number of parallel downloads for every queue item
  • -x 16 : The maximum number of connections to one server for each download
  • --disk-cache=64M : Enable disk cache
  • --allow-overwrite: Restart download from scratch if the corresponding control file doesn't exist
  • -c : Continue downloading a partially downloaded file

How to build ICON2 image from source

How to create a keystore file

A certificate is required to operate a node. There are two ways to create a certificate file or keystore file.

  • When you start a docker, you can create a certificate using IS_AUTOGEN_CERT environment variables.
      environment:
         IS_AUTOGEN_CERT: "true"
         KEY_PASSWORD: "password123!@#"
  • ${CERT_PATH}/autogen_cert.pem file is created with password password123!@#
  • You can create a certificate through the goloop cli command
# docker exec -it icon2-node goloop ks gen \
    --out keystore.json \ 
    --password YOUR_PASSWORD
  • keystore.json file is created with password YOUR_PASSWORD
  • If you have the der or pem file, run the following on the ICON2 server.
    You can convert it to json keystore with the command below. (The example below creates a private der.json file in the config directory)
$ docker exec -it icon2-node icon_wallet.py convert --filename private_der.der --password 1234  -vvv
I|20211024-11:12:08.000084|-|BOOTING.LOG|configure.py:91| Download new configuration

Arguments = Namespace(command='convert', filename='/goloop/config/private_der.der', password='1234', verbose=3)

Keystore file: /goloop/config/private_der.der, Keystore file type: der


hx address from der file : hxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
hx address from ICON wallet : hxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Convert file
Convert '/goloop/config/private_der.der' to '/goloop/config/private_der.json'
filename=/goloop/config/private_der.json, password=1234, keysecret=/goloop/config/keysecret

Create a Keystore file
	 Write to file => /goloop/config/private_der.json

    "address": "hxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
    "crypto": {
        "cipher": "aes-128-ctr",
        "cipherparams": {

}
	 Write to file => /goloop/config/private_der.json

How to control the ICON2 node

The command below is automatically executed in the container.

  • join : Join the network
  • leave: Leave the chain. When you execute this command, DB will be deleted and left the network

The command below can control the Goloop in the container.

  • start: Start the chain
docker exec -it icon2-node goloop chain start 0x1 # cid

or

docker exec -it icon2-node control_chain start

	 version : 0.1.29

✔ [DONE] 	['start'] count=0, func=view_chain, args=[], wait_state='started', check_state='started'
[2021-10-22 14:03:02.094] OK
  • stop: Stop the chain
docker exec -it icon2-node goloop chain stop 0x1  # cid

or

docker exec -it icon2-node control_chain stop

 version : 0.1.29
✔ [DONE] 	['stop'] count=0, func=view_chain, args=[], wait_state='stopped', check_state='stopped'
[2021-10-22 14:02:56.015] OK
  • ls: get the state
$ docker exec -it icon2-node goloop chain ls
[
  {
    "cid": "0x800c97",
    "nid": "0x53",
    "channel": "icon_dex",
    "state": "started",
    "height": 1034552,
    "lastError": ""
  }
]

or

$ docker exec -it icon2-node control_chain ls -f

	 version : 0.1.29
