请教bash调用expect问题，自动配置集群免密登录~~！自动集群SCP无法成功。

counterbyte

bash程序自动读取文件里面的IP地址然后执行Keys_scp.exp，并把参数传给Keys_scp.exp

#! /bin/bash

read -s PASSWD

ST_IP="HOST_IP.txt"
while read line_str ; do
        /usr/bin/expect -f ./Keys_scp.exp $line_str $PASSWD </dev/null
done < ${HOST_IP}

exit 0


Keys_scp.exp  接收参数并实现自动拷贝

#!/usr/bin/expect -f   

set PORT 22
set USER root
set HOST [lindex $argv 0]
set PASSWD [lindex $argv 1]
spawn scp -P $PORT -r /root/.ssh/id_rsa.pub $USER@$HOST:/root/.ssh/authorized_keys

set timeout -1

expect {
                    "*yes/no*" { send "yes\r"; expect "*password:*" { send "$PASSWD\r" } }
                            "*password:*" { send "$PASSWD\r" }
}

执行后出现的信息：
spawn scp -P 22 -r /root/.ssh/id_rsa.pub root@192.168.0.91:/root/.ssh/authorized_keys
root@192.168.0.91's password:
spawn scp -P 22 -r /root/.ssh/id_rsa.pub root@192.168.0.93:/root/.ssh/authorized_keys
root@192.168.0.93's password:
spawn scp -P 22 -r /root/.ssh/id_rsa.pub root@192.168.0.106:/root/.ssh/authorized_keys
root@192.168.0.106's password:

单独运行Keys_scp.exp  是可以的成功拷贝的~！
