How to transfer ETH between two addresses using geth and json rpc

Question

I have geth running on my server. I am building a php website which act as wallet. Now iam able to create addresses. I need to be able to deposit and withdraw ETH between addresses on same node. I start geth with below command.

go-ethereum/build/bin/geth console  --rpc --rpcapi="db,eth,net,web3,personal,web3" --rpccorsdomain "*" --syncmode "light"

How to acheive the functionality of a wallet on geth over rpc ? Is there a command or API call for that? Iam finding it hard to understand the documentation.

UPDATE: What I want to do is transfer ETH from one account to another. Below are the api calls i tried and the errors I got in the browser when i call transfer function in my php class. Can someone please correct me

Answer 1

In Geth console, you can use the sendTransaction function :

web3.eth.sendTransaction({
    from: "0xE618A4B5A516f371Ce26d9A1DBE7839F4e3812GB",
    to: "0xE618A4B5A516f371Ce26d9A1DBE7839F4e3812CB",
    value: web3.toWei(1, "ether")
})

Answer 2

You can use eth_sendtransaction to send a transaction to the destination

In the params section

params: [{
    "from": "0xb60e8dd61c5d32be8058bb8eb970870f07233155",
    "to": "0xd46e8dd67c5d32be8058bb8eb970870f07244567",
    "gas": "0x76c0", // 30400
    "gasPrice": "0x9184e72a000", // 10000000000000
    "value": "0x9184e72a", // 2441406250
    "data": "0xd46e8dd67c5d32be8d46e8dd67c5d32be8058bb8eb970870f072445675058bb8eb970870f072445675"
}]

You should get back a transaction signature

{
    "id":1,
    "jsonrpc": "2.0",
    "result": "0xe670ec64341771606e55d6b4ca35a1a6b75ee3d5145a99d05921026d1527331"
}

This works on accounts that have been unlocked in geth previously
