通过shell脚本连接远程机器，使用以下命令:

sshpass -p PASSWORD ssh -o StrictHostKeyChecking=no USERNAME@IPADDRESS

其中IPADDRESS, USERNAME和PASSWORD是需要在脚本中提供的输入值，或者如果我们想在运行时提供，使用“read”命令。

如此:

#!/usr/bin/expect -f
spawn ssh USERNAME@SERVER "touch /home/user/ssh_example"
expect "assword:"
send "PASSWORD\r"
interact

但是! !如果出现如下错误，只需使用expect而不是bash启动脚本，如下所示 而不是bash mysh .sh

/bin/myssh.sh: 2: spawn: not found /bin/myssh.sh: 3: expect: not found /bin/myssh.sh: 4: send: not found /bin/myssh.sh: 5: expect: not found /bin/myssh.sh: 6: send: not found

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。

这是我登录服务器的方式:

ssp <server_ip>

别名ssp = ' / home / myuser /文件/ ssh_script.sh” 猫/home/myuser/Documents/ssh_script.sh

ssp:

#!/bin/bash

sshpass -p mypassword ssh root@$1

因此:

ssp server_ip

在ubuntu linux -

ssh username@server_ip_address -p port_number

按enter键，然后输入服务器密码

如果您不是root用户，请在命令的开头添加sudo

在寻找这个问题的答案几个月后，我终于找到了一个更好的解决方案:写一个简单的脚本。

#!/usr/bin/expect

set timeout 20

set cmd [lrange $argv 1 end]
set password [lindex $argv 0]

eval spawn $cmd
expect "password:"
send "$password\r";
interact

把它放在/usr/bin/exp，所以你可以使用:

Exp <password> SSH <任何> Exp <password> SCP <anysrc> <anydst>

完成了!
