Node Installation

1. Checking OS

Currently, OS supports Ubuntu 18.04, CentOS 7.

~# cat /etc/os-release
    NAME="Ubuntu"
    VERSION="18.04.4 LTS (Bionic Beaver)"
~# apt-get update && \
      apt-get -y install sudo
~# sudo apt update
~# sudo apt upgrade
~# sudo apt install jq curl wget vim tar openssh-server net-tools -y
 # if it already installed it automatically skips

2. Checking HOME folder

~# export | grep HOME
    declare -x HOME="/home/omnione" | declare -x HOME="/root"
# in case, HOME="/root"
~# usermod -d /home/omnione <UserName>

3. Install Java and check

~# sudo apt install openjdk-8-jdk
~# java -version
    openjdk version "1.8.0_232"
    OpenJDK Runtime Environment (AdoptOpenJDK)(build 1.8.0_232-b09)
    OpenJDK 64-Bit Server VM (AdoptOpenJDK)(build 25.232-b09, mixed mode)

4. Install eosio/eosio.cdt

~# mkdir install
~# cd install

# eosio
~/install# git clone --recursive [source URL]

Check installation

~/install# nodeos -v
    v2.0.5
~/install# keosd -v
    v2.0.5
~/install# cleos version client
    v2.0.5
~/install# whereis nodeos
    nodeos: /usr/bin/nodeos
~/install# ls -al /usr/bin/nodeos
    lrwxrwxrwx 1 root root 29 Apr 21 18:08 /usr/bin/nodeos -> ../opt/eosio/2.0.5/bin/nodeos

5. Install Contract

~# cd ~
~# git clone --recursive [source URL]
~# cd ./eosio.contract/
~eosio.contracts# ./build.sh
~eosio.contracts# cd ./build/contracts/
~eosio.contracts/build/contracts# pwd
    /home/omnione/eosio.contracts/build/contracts

Addresses from pwd command are used to deploy the contact in the next step.

6. create Wallet and executing Wallet(keosd)

Wallet create

# cleos wallet create --to-console
Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5Kewn9L76X8Fpd....................t42S9XCw2"

Save the Wallet's password separately -> "PW5Kewn9L76X8Fpd....................t42S9XCw2"

Check Wallet open and List

# wallet open
~# cleos wallet open

# wallet list
~# cleos wallet list
Wallets:
[
  "default"
]

Check Wallet folder

# wallet 폴더 확인
~# ls -al $HOME/eosio-wallet
total 16
drwxr-xr-x 2 root root 4096 Jul 13 06:10 .
drwx------ 1 root root 4096 Jul 13 06:10 ..
-rw-r--r-- 1 root root 2900 Jul 10 05:42 config.ini
-rw------- 1 root root  439 Jul 10 05:45 default.wallet

Execute keosd

~# pkill keosd # 실행중인 keosd 중지 후 실행
~# keosd wallet open
~# cleos wallet unlock --password PW123...XYZ

Check Wallet

# wallet open 확인 (default, 별(*) 표시가 있어야 합니다.)
~# cleos wallet list
Wallets:
[
  "default *"
]

7. import Private Key to the executed Wallet

-> Script file / command (TBD)

~# cleos wallet import --private-key privateKey1Ddhs..................AM6KU2rdWSkA
imported private key for: EOS7WD2KwZLof..................KUzJyePLFqGNknytq

~# cleos wallet import --private-key privateKey2FdSF..................df6KU2reTXas
imported private key for: EOS5jtZK8qVAC..................kv1pTmyaoe24McGMv

Key check

~# cleos wallet private_keys --password PW5Jw8uKkk..........Ty97VN7oDHsrg
[
  [
    "EOS7WD2KwZLof..................KUzJyePLFqGNknytq",
    "privateKey1Ddhs..................AM6KU2rdWSkA"
  ],[
    "EOS5jtZK8qVAC..................kv1pTmyaoe24McGMv",
    "privateKey2FdSF..................df6KU2reTXas"
  ]
]
