Once the Droplet is created, SSH into the server using a terminal or SSH client. Finally, run the necessary commands to install R and its dependencies. Enjoy using R on your DigitalOcean server!
Ssh Key Authentication
To access your DigitalOcean server, you’ll need to set up SSH key authentication. This is a more secure method than using a password, as it uses encryption to ensure that only you can access your server. To set up SSH key authentication, you’ll need to generate a public and private key pair on your local machine. You can do this using the command `ssh-keygen` in your terminal. Once you’ve generated your keys, you’ll need to add your public key to your DigitalOcean account. You can do this by navigating to the “Settings” tab in your DigitalOcean dashboard, clicking “Security,” and then clicking “Add SSH Key.” Paste your public key into the “SSH Key Content” field, and give your key a name. Then click “Add SSH Key” to save your changes.Logging In Via Ssh
Now that you’ve set up SSH key authentication, you can log in to your server via SSH. To do this, open your terminal and type the following command: “` ssh root@your_server_ip_address “` Replace “your_server_ip_address” with the IP address of your DigitalOcean server. If this is your first time connecting to the server, you may see a warning message. Type “yes” to continue. You’ll be prompted to enter the passphrase for your private key. Once you’ve done that, you’ll be logged in to your server. Congratulations! You’ve successfully accessed your DigitalOcean server. From here, you can install R and any other software you need to run your applications.Installing R On Ubuntu
Learn how to easily install R on Ubuntu 16. 04 in DigitalOcean with this step-by-step guide. By following these instructions, you can quickly get started with R programming on your Ubuntu server.
Installing R on Ubuntu is a straightforward process that can be done in just a few steps. In this guide, we will walk you through the process of installing R on a DigitalOcean Ubuntu 16.04 droplet.
