我想我没有看到任何人提出这个建议，而操作人员只是说“脚本”，所以……

我需要解决同样的问题，而我最舒服的语言是Python。

我用了paramiko图书馆。此外，我还需要使用sudo发布需要升级权限的命令。事实证明，sudo可以通过“-S”标志通过stdin接受其密码!见下文:

import paramiko

ssh_client = paramiko.SSHClient()

# To avoid an "unknown hosts" error. Solve this differently if you must...
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# This mechanism uses a private key.
pkey = paramiko.RSAKey.from_private_key_file(PKEY_PATH)

# This mechanism uses a password.
# Get it from cli args or a file or hard code it, whatever works best for you
password = "password"

ssh_client.connect(hostname="my.host.name.com",
                       username="username",
                       # Uncomment one of the following...
                       # password=password
                       # pkey=pkey
                       )

# do something restricted
# If you don't need escalated permissions, omit everything before "mkdir"
command = "echo {} | sudo -S mkdir /var/log/test_dir 2>/dev/null".format(password)

# In order to inspect the exit code
# you need go under paramiko's hood a bit
# rather than just using "ssh_client.exec_command()"
chan = ssh_client.get_transport().open_session()
chan.exec_command(command)

exit_status = chan.recv_exit_status()

if exit_status != 0:
    stderr = chan.recv_stderr(5000)

# Note that sudo's "-S" flag will send the password prompt to stderr
# so you will see that string here too, as well as the actual error.
# It was because of this behavior that we needed access to the exit code
# to assert success.

    logger.error("Uh oh")
    logger.error(stderr)
else:
    logger.info("Successful!")

希望这能帮助到一些人。我的用例是在大约300台服务器上创建目录、发送和解压文件以及启动程序。因此，自动化至关重要。我试过sshpass, expect，然后想到了这个。

我得到了这个工作如下

.ssh/config被修改以消除是/否提示-我在防火墙后面，所以我不担心欺骗ssh密钥

host *
     StrictHostKeyChecking no

为expect创建一个响应文件，即answer.expect

set timeout 20
set node [lindex $argv 0]
spawn ssh root@node service hadoop-hdfs-datanode restart

expect  "*?assword {
      send "password\r"   <- your password here.

interact

创建bash脚本并在文件中调用expect

#!/bin/bash
i=1
while [$i -lt 129]    # a few nodes here
  
  expect answer.expect hadoopslave$i

  i=[$i + 1]
  sleep 5

done

获取128个用新配置刷新的hadoop datanode -假设您正在为hadoop/conf文件使用NFS挂载

希望这能帮助到一些人——我是一个Windows傻瓜，这花了我大约5个小时才弄明白!

这应该在大多数情况下都有帮助(你需要先安装sshpass !):

#!/usr/bin/bash
read -p 'Enter Your Username: ' UserName;
read -p 'Enter Your Password: ' Password;
read -p 'Enter Your Domain Name: ' Domain;

sshpass -p "$Password" ssh -o StrictHostKeyChecking=no $UserName@$Domain

使用公钥认证:https://help.ubuntu.com/community/SSH/OpenSSH/Keys

在源主机中只运行一次:

ssh-keygen -t rsa # ENTER to every field
ssh-copy-id myname@somehost

这就是全部，之后你就可以不用密码使用ssh了。

# create a file that echo's out your password .. you may need to get crazy with escape chars or for extra credit put ASCII in your password...
echo "echo YerPasswordhere" > /tmp/1
chmod 777 /tmp/1

# sets some vars for ssh to play nice with something to do with GUI but here we are using it to pass creds.
export SSH_ASKPASS="/tmp/1"
export DISPLAY=YOURDOINGITWRONG
setsid ssh root@owned.com -p 22
