ssh多机推送公钥不会出现密码认证

#!/usr/bin/env bash
while read ip

do
{

    ping -c1 -W1 $ip &>/dev/null
    if [ $? -eq 0 ];then
            /usr/bin/expect <<-EOF
            spawn ssh-copy-id root@$ip
            expect {
                    "yes/no" { send "yes\r"; exp_continue }
                    "password:" { send "123456\r" }
            }
            expect eof
            EOF
    fi
    }&

done </ip.txt

wait

以上是推送的脚本

下面是执行后的情况

spawn ssh-copy-id root@192.168.95.128
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/

id_rsa.pub"

Are you sure you want to continue connecting (yes/no)? yes

/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

执行到这里就停了，按理说应该继续输入密码推送成功的才对
