Overview
When deploying code to a server, you may encounter an SSH key recognition issue, resulting in a "Permission denied (publickey)" error. This can occur if the SSH key is not correctly configured or if there are permission issues. This article provides steps to verify and resolve SSH key issues to ensure successful deployment.
Information
To resolve SSH key recognition issues during deployment, follow these steps:
-
Verify SSH Key Addition:
- Access the server and check the
~/.ssh/authorized_keysfile to ensure your public key is correctly added. - If not, add it by running:
echo your_public_key >> ~/.ssh/authorized_keys
- Access the server and check the
-
Use
ssh-add:- Start the SSH agent with:
eval "$(ssh-agent -s)" - Add your private key to the SSH agent using:
ssh-add path_to_your_private_key
- Start the SSH agent with:
-
Check SSH Configuration:
- Verify that your local machine's SSH configuration uses the correct private key by checking the
~/.ssh/configfile. - Ensure the correct
IdentityFileis specified.
- Verify that your local machine's SSH configuration uses the correct private key by checking the
-
Permissions Check:
- Ensure the permissions on the
~/.sshdirectory andauthorized_keysfile are correctly set by running:chmod 700 ~/.ssh chmod 600 ~/.ssh/authorized_keys
- Ensure the permissions on the

Frequently Asked Questions
- What should I do if I don't have an SSH key pair?
- If you don't have an SSH key pair, you should generate one using an SSH key generation command, such as
ssh-keygen -t rsa, and then follow the steps to add the public key to your server and the private key to your SSH agent. - Why did my SSH key setup stop working without any changes?
- There could be several reasons, such as server configuration changes, updates, or permission alterations. It's essential to verify the current setup and permissions to ensure they align with the required configuration.
