Setting up SSH keys on a Red Hat Enterprise Linux 8 (RHEL 8) system allows you to log in to a remote server without having to enter a password. Here is an overview of the steps to set up SSH keys on RHEL 8:<\/p>\n

    \n
  1. Start by creating a new key pair on your local machine. This can be done using the ssh-keygen command:<\/li>\n<\/ol>\n
    \n
    <\/div>\n
    ssh-keygen -t rsa -b<\/span> 4096<\/span>
    \n<\/code><\/div>\n<\/div>\n

    This will create a new RSA key pair in the ~\/.ssh directory, with the private key stored in the file id_rsa and the public key stored in the file id_rsa.pub.<\/p>\n

      \n
    1. Copy the public key to the remote server by using the ssh-copy-id command:<\/li>\n<\/ol>\n
      \n
      <\/div>\n
      ssh-<\/span>copy<\/span>-<\/span>id user<\/span>@remote<\/span>-<\/span>server-<\/span>ip
      \n<\/code><\/div>\n<\/div>\n

      This will copy the public key to the remote server, and add it to the authorized_keys file in the ~\/.ssh directory on the remote server.<\/p>\n

        \n
      1. Test the connection to the remote server without a password:<\/li>\n<\/ol>\n
        \n
        <\/div>\n
        ssh user<\/span>@remote<\/span>-<\/span>server-<\/span>ip
        \n<\/code><\/div>\n<\/div>\n
          \n
        1. If you are using SELinux on your RHEL 8 system, you may need to configure it to allow SSH key-based authentication. You can do this by running the following command:<\/li>\n<\/ol>\n
          \n
          <\/div>\n
          sudo setsebool -P ssh_use_syslog on<\/span>
          \n<\/code><\/div>\n<\/div>\n
            \n
          1. To disable SSH password authentication and enable SSH key-based authentication, open the SSH configuration file:<\/li>\n<\/ol>\n
            \n
            <\/div>\n
            sudo nano \/etc\/ssh\/sshd_config
            \n<\/code><\/div>\n<\/div>\n

            and change the following lines:<\/p>\n

            \n
            <\/div>\n
            PasswordAuthentication<\/span> no<\/span>
            \nPubkeyAuthentication<\/span> yes<\/span>
            \n<\/code><\/div>\n<\/div>\n
              \n
            1. Restart the SSH service:<\/li>\n<\/ol>\n
              \n
              <\/div>\n
              sudo systemctl restart sshd
              \n<\/code><\/div>\n<\/div>\n
                \n
              1. You can also configure ssh-agent so that you don’t have to enter the passphrase every time you log in to the remote server. You can start the ssh-agent service and add your key to the ssh-agent keychain with the following commands:<\/li>\n<\/ol>\n
                \n
                <\/div>\n
                eval<\/span> \"$(ssh-agent -s)\"<\/span>
                \nssh-add ~\/.ssh\/i<\/span>d_rsa
                \n<\/code><\/div>\n<\/div>\n
                  \n
                1. To remove ssh key from ssh-agent keychain you can use<\/li>\n<\/ol>\n
                  \n
                  <\/div>\n
                  ssh-add -d ~\/.ssh\/i<\/span>d_rsa
                  \n<\/code><\/div>\n<\/div>\n

                  By following these steps, you can set up SSH keys on a RHEL 8 system, and use them to log in to a remote server without having to enter a password. Additionally, you can configure SELinux and SSH configuration file to allow SSH key-based authentication and disable SSH password authentication. You can also start the ssh-agent service and add your key to the ssh-agent keychain so that you don’t have to enter the passphrase every time you log in to the remote server.<\/p>\n","protected":false},"excerpt":{"rendered":"
