Python:如何通过SSH执行多个命令,而无需在每个命令中登录

在Python中,可以使用paramiko库来通过SSH执行多个命令,而无需在每个命令中登录。paramiko是一个用于SSHv2协议的Python实现,可以用于远程执行命令、上传和下载文件等操作。

以下是一个示例代码,演示如何使用paramiko库通过SSH执行多个命令:

代码语言:txt
复制
import paramiko

# 创建SSH客户端对象
ssh = paramiko.SSHClient()

# 自动添加远程主机的SSH密钥
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# 连接远程主机
ssh.connect('远程主机IP', port=22, username='用户名', password='密码')

# 执行多个命令
commands = [
    'command1',
    'command2',
    'command3'
]

for command in commands:
    # 执行命令
    stdin, stdout, stderr = ssh.exec_command(command)

    # 获取命令执行结果
    output = stdout.read().decode('utf-8')

    # 打印命令执行结果
    print(output)

# 关闭SSH连接
ssh.close()

在上述代码中,需要将远程主机IP替换为实际的远程主机IP地址,用户名密码替换为实际的SSH登录凭证。commands列表中存储了需要执行的多个命令,可以根据实际需求进行修改。

安装:pip install Paramiko paramiko是用python语言写的一个模块,遵循SSH2协议,支持以加密和认证的方式,进行远程服务器的连接。 使用paramiko可以很好的解决以下问题: 需要使用windows客户端, 远程连接到Linux服务器,查看上面的日志状态,批量配置远程服务器,文件上传,文件下载等 "paramiko" is a combination of the esperanto words for "paranoid" and "friend".  it's a module for python 2.5+ that implements the SSH2 protocol for secure (encrypted and authenticated) connections to remote machines. unlike SSL (aka TLS), SSH2 protocol does not require hierarchical certificates signed by a powerful central authority. you may know SSH2 as the protocol that replaced telnet and rsh for secure access to remote shells, but the protocol also includes the ability to open arbitrary channels to remote services across the encrypted tunnel (this is how sftp works, for example). it is written entirely in python (no C or platform-dependent code) and is released under the GNU LGPL (lesser GPL). the package and its API is fairly well documented in the "doc/" folder that should have come with this archive. Requirements ------------  - python 2.5 or better <http://www.python.org/>  - pycrypto 2.1 or better <https://www.dlitz.net/software/pycrypto/> If you have setuptools, you can build and install paramiko and all its dependencies with this command (as root)::    easy_install ./ Portability ----------- i code and test this library on Linux and MacOS X. for that reason, i'm pretty sure that it works for all posix platforms, including MacOS. it should also work on Windows, though i don't test it as frequently there. if you run into Windows problems, send me a patch: portability is important to me. some python distributions don't include the utf-8 string encodings, for reasons of space (misdirected as that is). if your distribution is missing encodings, you'll see an error like this::    LookupError: no codec search functions registered: can't find encoding this means you need to copy string encodings over from a working system. (it probably only happens on embedded systems, not normal python installs.) Valeriy Pogrebitskiy says th
