tag-icon • tag-icon ssh bash expect
！/usr/bin/env bash

从 bash 脚本：

source ./expect.sh

我包括一个期望代码：

#!/bin/bash
/usr/bin/expect <<EOL
spawn ssh-copy-id -i /home/user/.ssh/id_rsa.pub 111.111.111
expect '*?assword*'
send 'thepassword'
interact
EOL

我得到了这个：

spawn ssh-copy-id -i /home/user/.ssh/id_rsa.pub 111.111.111.111
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
[email protected]'s password:

然后我尝试连接并提示我输入密码...

检查服务器后，我确定没有上传密钥，因为我希望列出“authorized_keys”文件：

root@server: ls /home/user/.ssh/
known_hosts

我究竟做错了什么？

答案1

问题在于 ssh 客户端直接从终端读取密码，而不是从 stdin 读取。

我知道的解决这个问题的最简单的方法是安装“sshpass”，然后使用它（不使用 Expect）：

sshpass -p "thepassword" ssh-copy-id -i /home/user/.ssh/id_rsa.pub [email protected]

答案2

以下脚本也可以解决问题

#!/usr/bin/expect -f
#
# Install RSA SSH KEY with no passphrase
#

set user [lindex $argv 0]
set host [lindex $argv 1]
set password [lindex $argv 2]
spawn ssh-copy-id -i /path/to/your/.ssh/id_rsa.pub $user@$host

expect {
    "continue" { send "yes\n"; exp_continue }
    "assword:" { send "$password\n"; }
}

您需要使其可执行，并按如下方式调用它：

./ssh-copy-id.exp <user> <host> <password>

就你的情况而言：

./ssh-copy-id.exp root 111.111.111.111 thepassword

答案3

您正在复制密钥，/root/.ssh/authorized_keys而不是用户帐户。请注意以下位置：[email protected]'s password:
