Introduction:
In today’s digital age, security is of utmost importance, especially when it comes to accessing your server. Using SSH keys is an excellent way to enhance security while granting access. In this guide, we’ll walk you through the process of creating and setting up SSH keys for secure server access.
Step 1: Create Your SSH Keys
To get started, follow these steps:
1.1. Open your server terminal: Log in to your server as the user you wish to create SSH keys for.
1.2. Create your SSH keys: Run the following command to generate your keys. Replace <username> with your username:
sudo adduser <username>
1.3. Generate your keys: Run this command to create your SSH keys. You’ll be prompted to set a passphrase for added security.
ssh-keygen -t rsa -C "The access key"
You’ll now have a private key (id_rsa) and a public key (id_rsa.pub).
Step 2: Set Up Your Authorized Keys
Now that you have your SSH keys, it’s time to set them up for secure access:
2.1. Copy the private key: Save your private key (id_rsa) in a safe place on your local machine.
2.2. Copy the public key: You’ll need to add your public key to the server’s authorized keys. Run the following command on your server to achieve this:
cat id_rsa.pub >> ~/.ssh/authorized_keys
With this setup, your server will now recognize your private key for secure access.
Step 3: Securely Share Your Public Key
To access your server from a remote machine, you need to securely share your public key. You can do this by posting it on your WordPress blog.
3.1. Locate your public key: Find your public key file (id_rsa.pub) on your local machine.
Conclusion:
By following these simple steps, you can enhance the security of your server while allowing authorized users to access it securely using SSH keys. This method is not only more secure than traditional passwords but also more convenient.
Remember to keep your private key safe, and you’ll be well on your way to maintaining a secure server environment.
