In this tutorial, I'll walk you through the steps to install and configure an Ethereum node on your Linux box. An Ethereum node allows you to participate in the Ethereum network, verify transactions and synchronize a copy of the blockchain.
Before you begin, make sure you have the following prerequisites:
- A Linux machine with internet connection
- Enough disk space to store the blockchain (around 200GB at time of last estimate)
Step 1: Install Golang
Before installing Ethereum Node, you will need to install the Golang programming language. You can do this by following these steps:
sudo apt update
sudo apt install -y golang
Step 2: Install Ethereum
Once Golang is installed, you can proceed to install the Ethereum node. Run the following commands:
go get -d github.com/ethereum/go-ethereum
cd $GOPATH/src/github.com/ethereum/go-ethereum/make geth
Now that you have successfully installed the Ethereum node, you can proceed with the setup. Perform the following steps:
Step 1: Create a new data directory
Create a new directory for your Ethereum node data. You can choose any name and location you like. For example:
Step 2: Create a configuration file
Create a new configuration file called "config.toml". You can do this by running the following command:
Step 3: Configure network options
Open the newly created configuration file with a text editor and add the following lines:
Name = "IlMioNodo"
NetworkId = 1
SyncMode = "fast"
Enabled = true
APIs = ["eth", "web3", "net"]
In the [Node] section, you can specify the name of your Ethereum node.
In the [Network] section, you can specify the ID of the Ethereum network you want to connect to. ID 1 corresponds to the main Ethereum network.
In the [RPC] section, you can enable RPC access to your Ethereum node and specify which APIs are available.
Start the Ethereum node
Now that you have completed installing and configuring the Ethereum node, you can start the node by running the following command:
$GOPATH/src/github.com/ethereum/go-ethereum/build/bin/geth --datadir ~/.ethereum
The Ethereum node will start synchronizing with the blockchain. This process may take some time, so please be patient.
In this tutorial, you learned how to install and configure an Ethereum node on your Linux machine. You are now ready to join the Ethereum network and use your node to verify transactions and synchronize the blockchain.
