Using web3js library, here is how you do it on nodejs serverside

//generate private key    
privateKey = web3.eth.accounts.create().privateKey.substr(2)

//generates pubKey from privateKey, encrypts it and store in keystore folder.
web3.eth.personal.importRawKey(privateKey, pin)
    .then((result) => {

    //store pub address.
    publicAddr = web3.utils.toChecksumAddress(result)
})

...

There you go.
