ssh_keys_authentication.sh

# Create ssh private and public keys on your local machine
ssh-keygen -t rsa

# Set permissions on your private key
chmod 700 ~/.ssh
chmod 600 ~/.ssh/id_rsa

# Copy the public key to the server
scp ~/.ssh/id_rsa.pub root@yourserver.com:~/.ssh/authorized_keys

# On the server, set permissions
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

# If you have SELinux enabled and your SSH Keys will not work
# try running the following command
restorecon -v /root/.ssh/authorized_keys

# If you want to turn SELinux off, while system is running
echo 0 > /selinux/enforce

# You can also turn SELinux off by updating config file
vi /etc/selinux/config

# and change
SELINUX=enforcing

# to
SELINUX=disabled
