-bash: ssh-copy-id: command not found

The first solution :( need yum tool)

yum install -y openssh-clients

:( second solution requires network)

curl -L https://raw.githubusercontent.com/beautifulcode/ssh-copy-id-for-OSX/master/install.sh | sh

A third solution to the above requirements do not have :()

The following two scripts in the same directory, execute this script needs to have sudo privileges or root user to perform

install_ssh-copy-id.sh script

#!/bin/sh
# Installs ssh-copy-id into /usr/local/bin
if [[ $(id -u) != 0 ]]; then
   if command -v sudo >/dev/null 2>&1; then
      SUDO="sudo"
   else
      echo >&2 "Requires sudo but it's not installed. Aborting."
      exit 1
  fi
fi

$SUDO cp ssh-copy-id.sh /usr/local/bin/ssh-copy-id || { echo "Failed to install ssh-copy-id into /usr/local/bin."; exit 1; }
$SUDO chmod +x /usr/local/bin/ssh-copy-id || { echo "Failed to install ssh-copy-id into /usr/local/bin."; exit 1; }

echo "Installed ssh-copy-id into /usr/local/bin."; exit 0;

cat <<EOF
Now try logging into the machine, with "ssh '$1'", and check in:

  .ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

EOF

The above two scripts in the same directory, execute this script requires root privileges or sudo

carried out:

 chmod u+x install_ssh-copy-id.sh

carried out:

./install_ssh-copy-id.sh

The second and third in the same way, just download the file to a local, then simply modify the script under
