To connect, remix to our private network, we need to change the Environment to Web3 Provider, under the tab Run. When you do this change, remix will prompt you to specify the Web3 Provider Endpoint — set the value http://localhost:8545. Unless you have changed the port explicitly, the default mining node will start on the port 8545.

Now we can deploy our smart contract to our private blockchain. Under the Run tab, make sure you have the right ethereum account selected, and then the right gas limit is specified. You can keep gas price and value as zero.

Code:
pragma solidity ^0.4.11;
contract Hello {
// a string variable
string public greeting;
// the function with the same name as the class is a constructor
function Hello(string _greeting) {
greeting = _greeting;
}
// change the greeting message
function setGreeting(string _greeting) {
greeting = _greeting;
}
// get the greeting message
function greet() constant returns (string _greeting) {
_greeting = greeting;
}
}
