使用Paramiko实现SSH登陆，文件上传下载

1，SSh登陆命令行实现：

#!/usr/bin/env python
# encoding: utf-8
import paramiko

private_key_path = ‘/Users/aolens/.ssh/id_rsa‘
key = paramiko.RSAKey.from_private_key_file(private_key_path)
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(‘192.168.1.201‘, 22,username=‘root‘,pkey=key)
#ssh.connect(‘192.168.1.201‘, 22,‘root‘,‘aolens‘) #不采用迷药登陆时
flag = True
while flag:
    con = raw_input(‘输入要执行的命令: ‘)
if con == ‘quit‘:
        flag = False
ssh.close()
else:
        stdin, stdout, stderr = ssh.exec_command(con)
print stdout.read()

2，实现文件上传下载

t = paramiko.Transport((‘192.168.1.201‘,22))
t.connect(username=‘root‘,password=‘qixiang123‘)
sftp = paramiko.SFTPClient.from_transport(t)
#sftp.put(‘/Users/aolens/Downloads/1.sh‘,‘/root/1.sh‘)   #put上传文件到服务器,前边是上传文件地址,后边是上传后文件地址
sftp.get(‘/root/1.sh‘,‘/Users/aolens/Downloads/2.sh‘)    #get下载文件,前边是下载地址,后边是下载后存放地址
t.close()

结合SSH登陆，优化文件上传下载

#!/usr/bin/env python
# encoding: utf-8

import paramiko

private_key_path = ‘/Users/aolens/.ssh/id_rsa‘
key = paramiko.RSAKey.from_private_key_file(private_key_path)

t = paramiko.Transport((‘192.168.1.201‘,22))
t.connect(username=‘root‘,pkey=key)
sftp = paramiko.SFTPClient.from_transport(t)
flag = True
while flag:
    con = raw_input(‘输入要执行的命令: ‘)
if con == ‘quit‘:
        flag = False
t.close()
elif con == ‘put‘:
        com_add = raw_input(‘输入文件来源地址:‘)
        target_add = raw_input(‘输入文件存放地址:‘)
        sftp.put(com_add,target_add)
print ‘上传完成[=========================] 100%  ‘, "文件上传至:%s"% (target_add)
elif con == ‘get‘:
        com_add = raw_input(‘输入文件来源地址:‘)
        target_add = raw_input(‘输入文件存放地址:‘)
        sftp.get(com_add,target_add)
print ‘下载完成[=========================] 100%  ‘, "文件存放在:%s"% (target_add)

else:
print ‘输入正确的上传下载指令‘
print ‘上传: put ‘
print ‘下载: get ‘
print ‘=========================‘

对上边SSH登陆优化，输出信息

#!/usr/bin/env python
# encoding: utf-8
import paramiko

private_key_path = ‘/Users/aolens/.ssh/id_rsa‘
key = paramiko.RSAKey.from_private_key_file(private_key_path)
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(‘192.168.1.201‘, 22,username=‘root‘,pkey=key)
#ssh.connect(‘192.168.1.201‘, 22,‘root‘,‘aolens‘) #不采用迷药登陆时
flag = True
while flag:
    con = raw_input(‘\033[1;34m输入要执行的命令: \033[0m‘)
    if con == ‘quit‘:
        flag = False
        ssh.close()
    else:
        stdin, stdout, stderr = ssh.exec_command(con)
	for i in (stdout.read(),stderr.read()):
		print i
