python 模块sshtunnel使用

需要用到的模块：sshtunnel,paramiko

通过sshtunnel建立客户端与跳板机的隧道，然后再通过paramiko链接服务器即可

常见配置如下：

import paramiko

from sshtunnel import SSHTunnelForwarder

with SSHTunnelForwarder (

    ('跳板机IP'，port1),

    ssh_username=username,

    ssh_pkey='/home/username/.ssh/xx',

    remote_bind_address=('你需要连接的服务器IP', port2),

    local_bind_address=('客户端IP', port3)

) as server:

    client = paramiko.SSHClient()

    client.load_system_host_keys()

    client.set_missing_host_key_policy(paramiko.AutoAddPolicy()

    client.connect('客户端IP', port3, username)

    stdin, stdout, stderr = client.exec_command(command)

    print stdout.read()

    client.close()

port1，port2为服务器开放端口，port3是自己定义的端口
