python中paramiko模块的使用

1、利用密码登录

#!/usr/bin/env python
#coding:utf8

import paramiko
import sys
host = sys.argv[1]
user = sys.argv[2]
password = sys.argv[3]
port = int(sys.argv[4])
cmd = sys.argv[5]


if __name__ == "__main__":
    paramiko.util.log_to_file('/root/test/testssh.log')
    s = paramiko.SSHClient()
    s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    s.connect(host,port,user,password)
    stdin,stdout,stderr=s.exec_command(cmd)
    print "--------Result from? %s -------" % host
    print stdout.read()
    s.close()

执行方式: python testssh.py 192.168.30.76 root password 22 "df -h"

2、利用key登录

#!/usr/bin/env python
#coding:utf8
import sys
import paramiko


host = sys.argv[1]
user = sys.argv[2]
port = int(sys.argv[3])
cmd = sys.argv[4]


if __name__ == "__main__":
    pkey = '/home/username/.ssh/id_rsa'
    key = paramiko.RSAKey.from_private_key_file(pkey)
    s = paramiko.SSHClient()
    s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    s.load_system_host_keys()
    s.connect(host,port,user,pkey=key)
    stdin,stdout,stderr=s.exec_command(cmd)
    print stdout.read()

运行方式:python testsshkey.py 192.168.80.88 username 22 "df -h"

3、上传文件到远程服务器

#!/usr/bin/env python
#coding:utf8


import paramiko
import sys

if __name__ == "__main__":
    t = paramiko.Transport(("192.168.30.76",22))
    t.connect(username = "root", password = "123abc")
    sftp = paramiko.SFTPClient.from_transport(t)
    remotepath='/tmp/testput.py'
    localpath='/root/test/testput.py'
    sftp.put(localpath,remotepath)
    t.close()

4、从远程服务器下载文件到本机

#!/usr/bin/env python
#coding:utf8


import paramiko
import sys

if __name__ == "__main__":
    t = paramiko.Transport(("192.168.30.76",22))
    t.connect(username = "root", password = "123abc")
    sftp = paramiko.SFTPClient.from_transport(t)
    remotepath='/tmp/testget.py'
    localpath='/tmp/testtget.py'
    sftp.get(localpath,remotepath)
    t.close()
