00 PREREQUISITES

0.1 – System Requirements

0.2 – Hardware & Software

1. Linux, Mac, or Windows computer running the latest operating system (OS) version.
   (For Demo: MacBook Pro + MacOS Monterey 12.2)

2. Terminal Emulator / SSH Client

   • Mac: Terminal || Windows: PuTTy || Linux: Ubuntu Server

3. Login credentials for the server being accessed.

0.3 – Enabling / Disabling Secure Shell (SSH)

To access the server remotely, the user must enable Secure Shell (SSH) on their home system.

1. Enter the following command/s in Terminal to enable / disable SSH on the system:

   Code Block
   language bash
   sudo systemsetup -setremotelogin on #Enable SSH sudo systemsetup -setremotelogin off #Disable SSH Password: [?] #System password

...

01 SETTING UP THE REMOTE SERVER

1.1 – Connecting to the Remote Server

1. To access the server with SSH, run the following Terminal command/s (replacing the details inside the {brackets} with your provided credentials):

   Code Block
   language bash
   ssh

...

1. username@server-ip-address #Server access login Password: [?] #Access password #Use [CTRL+D] at anytime to suspend the connection.

1.2 – Optimize the Server for Node Operations

Once you’re connected to the server with SSH, follow the steps below to setup and install the dependencies required for your node.

1. Update the Ubuntu System and upgrade the OS components.

   Code Block
   language bash
   sudo apt update && apt upgrade && autoremove -y

1. Install the latest version of GoLang.

   1. Check and remove the existing GoLang version.

      Code Block
      language bash
      go version #displays the existing version sudo apt purge golang* #removes the existing Go version

   2. Use purge to remove the existing version; then, use wget to install the latest version.

      Code Block
      language bash
      sudo apt purge golang* #Removes the existing Go version. wget https://go.dev/dl/go1.17.7.linux-amd64.tar.gz #Installs the current version (go1.17.7 as of 2022-02-14). sudo tar -C /usr/local -xzf go1.11.4.linux-amd64.tar.gz #Extracts Go in the /usr/local folder mkdir ~/.go

   3. Set the environmental variables and $PATH location.

      Code Block
      language bash
      GOROOT=/usr/local/go GOPATH=~/.go PATH=$PATH:$GOROOT/bin:$GOPATH/bin

   4. Update the Go command.

      Code Block
      language bash
      sudo update-alternatives --install "/usr/bin/go" "go" "/usr/local/go/bin/go" 0 sudo update-alternatives --set go /usr/local/go/bin/go

   5. Confirm Go was updated to the latest version.

      Code Block
      language bash
      go version

2. Code Block
   go version

Top-level Updates

The following demonstration will exhibit the step-by-step processes of:

1. Logging into the system

   1. Username & password login by default

   2. Secure user credentials with a Public SSH Key.

      1. Option A → Run ssh-keygen command:

         Code Block
         ssh-keygen -t rsa

         Code Block

      3. Option B → ls -al .ssh

      4. fdafdasd

         Code Block
         ssh-keygen -t rsa

2. Get Erigon

3. Run Erigon + Setup as a service so it will run again after rebooting

4. Change the hostname of the server

5. Make an exception for SSH, then turn on the firewall.

6. Open Erigon port 30303 through the firewall to allow incoming connections to the node (allows for a trustless, distributed system).

7. Setup DNS so it can be accessed with a domain name.
