1.paramiko安装
1)安装PyCrypto2.6 for Python 2.7 64bit。地址:http://www.voidspace.org.uk/python/modules.shtml#pycrypto
直接双击安装
2)安装ecdsa-0.10.tar.gz,地址:https://pypi.python.org/packages/source/e/ecdsa/ecdsa-0.10.tar.gz
解压缩后cd到目录下用python setup.py install命令安装
3)安装paramiko,地址:https://pypi.python.org/packages/source/p/paramiko/paramiko-1.12.1.tar.gz
同样用python setup.py install命令安装
2.使用paramiko远程登录到linux机器并执行命令
直接上代码
import paramiko_default_port = 22
def ssh(cmd, ip, usernamer, passwd):
"""
远程到目标机器并执行命令,返回执行结果
"""
out = None
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
ssh.connect(ip,_default_port,username,passwd,timeout=5)
stdin, stdout, stderr = ssh.exec_command(cmd)
out = stdout.readlines()
except Exception as e:
print 'ssh to %s\tError\n reason:%s'%(ip,e)
finally:
if ssh:
ssh.close()
return out
3.上传文件到目标机器
def upload(remotepath, localpath, ip, port, username, passwd):
t = paramiko.Transport((ip, port))
try:
t.connect(username=username,password=passwd)
sftp = paramiko.SFTPClient.from_transport(t)
sftp.put(localpath,remotepath)
except Exception as e:
print 'upload file to %s\tError\n reason:%s'%(ip,e)
finally:
if t:
t.close()
4.从目标机器下载文件
def download2(remotepath, localpath, ip, port, username, passwd):
t = paramiko.Transport((ip, port))
try:
t.connect(username=username,password=passwd)
sftp = paramiko.SFTPClient.from_transport(t)
sftp.get(remotepath,localpath)
except Exception as e:
print 'download file from %s\tError\n reason:%s'%(ip,e)
finally:
if t:
t.close()
paramiko没有直接上传下载文件夹的方法,可以用os.walk()等方法来遍历文件夹实现依次上传或下载。
