How to install your SSH key on a remote server
1*. Nice way*
You can install an SSH key by executing
ssh-copy-id [email protected]
Now you can log in to the remote server with your password and ssh-copy-id will do the rest.
2. Manual way
Append your public ssh key to the authorized_key
file on the server.
As a one-liner:
cat ~/.ssh/id_rsa.pub | ssh [email protected] 'cat>> ~/.ssh/authorized_keys'
Conclusion
Both commands pretty much do the same. The first way is way easier though.
The next time you can connect to the server using your SSH key.
