Setting up a shared VPS on Vultr . SSH Keys.

When setting up a shared VPS on Vultr and configuring SSH Keys for Linux, here's what you need to do:

1. Generate an SSH Key Pair (if you don’t already have one):

• On Linux or macOS, open a terminal and run:

    ssh-keygen -t rsa -b 4096
  

• Save the key pair to the default location (~/.ssh/id_rsa) or specify a custom path.

• You’ll get two files:

  • Private Key: id_rsa (keep this secure, never share it).

  • Public Key: id_rsa.pub (upload this to Vultr).

2. Add the SSH Key to Vultr:

• Go to your Vultr dashboard.

• Navigate to SSH Keys under the Products section.

• Click Add SSH Key.

• Paste the contents of your public key (id_rsa.pub) into the field.

• Give it a name (e.g., my-linux-key) and save it.

3. Select the SSH Key During VPS Deployment:

• When deploying your VPS, under Server Settings, select the SSH key you just added.

• This ensures secure, password-less login to your VPS.

4. Access Your VPS Using SSH:

• Once the VPS is deployed, connect to it using:

    ssh -i /path/to/private_key root@your_vps_ip
  

• Replace /path/to/private_key with the path to your private key and your_vps_ip with the IP address of your VPS.

Why Use SSH Keys?

• Security: SSH keys are more secure than passwords.

• Convenience: No need to remember or type passwords.

• Automation: Easier to automate tasks like deployments.
