Compile

cd inrcrud
cd; source .bashrc; cd -
inery-cpp -abigen -o inrcrud.wasm inrcrud.cpp

Set Contract

cline set contract namaAkun ./

Unlock wallet dulu jika ke lock

cline wallet unlock -n namaAkun --password passwordDariFileTXT

Jika muncul seperti ini

Edit file config.ini

cd ~/inery-node/inery.setup/master.node/blockchain/config

nano config.ini

Temukan max-transaction-time (yang paling bawah) ganti dari 15000 ke 30000

SAVE, CTRL+X Y Enter

Contract siap ,lanjut membuat JSON RPC

Install Nodejs

sudo apt update
curl -fsSL https://deb.nodesource.com/setup_19.x | sudo -E bash - &&\
sudo apt-get install -y nodejs

Clone Repo

cd
git clone https://github.com/alteregogi/ineryjs.git
cd ineryjs

Install

npm install

Jika muncul seperti itu ,update menggunakan

npm install -g npm@9.2.0

Copy dan Edit file .env

cp .env-sample /root/ineryjs/.env
nano .env

Isi dengan data mu sesuai di dashboard. http://you_node_url:8888 ganti dengan http://IP.VPSMU:8888 Save

Jalankan

npm run rpc-example

OKAY!

Jika ada error seperti ini;

cause: Error: connect ECONNREFUSED IP.VPS:8888

Cara fix nya open port 8888

sudo ufw allow 8888; sudo ufw enable
