1. Generate private/public keys
ssh-keygen -t rsa
2. Upload the public key (id_rsa.pub) to remote server
scp ~/.ssh/id_rsa.pub howard@remoteServer:~/.ssh/
or
cat ~/.ssh/id_rsa.pub | ssh howard@remoteServer "cat >> ~/.ssh/authorized_keys"
3. Login to remote server and append the key
ssh howard@remoteServer
mkdir .ssh
chmod 700 .ssh
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
rm -rf id_rsa.pub
4. It's done!
To convert RSA private key to pem file, run the command below:
openssl rsa -in ~/.ssh/id_rsa -outform pem > id_rsa.pem
