Prueba en Rinkeby

Estoy tratando de probar en Rinkeby, así que ejecuté el siguiente comando

geth --rpc --rpcaddr localhost --rpcport 8545

Dentro de mi archivo Javascript tengo el siguiente código

if (typeof web3 !== 'undefined') {
        window.web3 = new Web3(web3.currentProvider);
        console.log(`Web 3 is: ${web3}`);
    } else {
        console.log('No web3? You should consider trying MetaMask!')
        window.web3 = new Web3(new Web3.providers.HttpProvider("http://localhost:8545"));
        console.log(window.web3);
    }

Sin embargo, todavía registra No web3? You should consider trying MetaMask!¿Qué es exactamente lo que estoy haciendo mal aquí? Configuré Rinkeby para que esté en localhost 8545.

Aquí está mi registro de terminal
