或者

yum install expect

!/usr/bin/expect  set timeout 10  set username [lindex $argv 0]  set password [lindex $argv 1]  set hostname [lindex $argv 2]  spawn ssh-copy-id -i /root/.ssh/id_rsa.pub $username@$hostnameexpect {            #first connect, no public key in ~/.ssh/known_hosts            "Are you sure you want to continue connecting (yes/no)?" {            send "yes\r"            expect "password:"                send "$password\r"            }            #already has public key in ~/.ssh/known_hosts            "password:" {                send "$password\r"            }            "Now try logging into the machine" {                #it has authorized, do nothing!            }        }expect eof
