I have developed a smart contract and compiled it with solc and bin and abi fils have been generated. Now, I want to deploy this contract using web3js in a linux server. How can I do it?

  • you can setup a private chin or a single geth node in your server. otherwise use ropsten network thorough metamask or myethewallet.

  • as you are new to the field, if you want just to test your code try to use instead testrpc or truffle. ethereum.stackexchange.com/questions/23842/…

  • @ Badr Bellaj Yes I am new to this field, but I have to deploy it in server.

To deploy a smart contract on ethereum, you have to make a deployment transaction.

A deployment transaction is send contract bytecode to empty address.

For example:

My add.sol

pragma solidity 0.5.1;

contract ADD {
    uint256 total;

    function add(uint256 a, uint256 b) public {
        total = a+b;

The bytecode of add.sol 608060405234801561001057600080fd5b5060b88061001f6000396000f3fe6080604052600436106039576000357c010000000000000000000000000000000000000000000000000000000090048063771602f714603e575b600080fd5b348015604957600080fd5b50607d60048036036040811015605e57600080fd5b810190808035906020019092919080359060200190929190505050607f565b005b808201600081905550505056fea165627a7a72305820e3f9b94abc880b4f5646678c218c6c79a98f8dad3a566a9822548d539b741a340029

The deployment transaction looks like:

    from: "0x......", // you have to unlock account first
    to: null,
    gas: 2000000,
    gasPrice: 1000000000,
    value: 0,
    data: "0x60806040523480156......"

You can call send transaction rpc through curl:

curl -vX POST localhost:8545 -d '{"method": "eth_sendTransaction", "id": 1, "params": [{"transaction object"}]}' -H "Content-Type: application/json"

Alternative you can call send raw transaction rpc if you want to sign with own private key:

curl -vX POST localhost:8545 -d '{"method": "eth_sendRawTransaction", "id": 1, "params": ["0x................."]}' -H "Content-Type: application/json"

so in a nutshell :

first: deploy a geth node in your server. here's a detailed tutorial https://medium.com/mercuryprotocol/how-to-create-your-own-private-ethereum-blockchain-dad6af82fc9f

second: once your node is running use Remix, connect it to your node RPC address and deploy directly from remix.
