pycrypto，由于 paramiko 模塊內部依賴pycrypto，所以先下載安裝pycrypto

pip3 install pycryptopip3 install paramiko

（1）基于用戶名和密碼的連接

import paramiko# 創(chuàng)建SSH對象ssh = paramiko.SSHClient()# 允許連接不在know_hosts文件中的主機ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())# 連接服務器ssh.connect(hostname=’c1.salt.com’, port=22, username=’GSuser’, password=’123’)# 執(zhí)行命令stdin, stdout, stderr = ssh.exec_command(’ls’)# 獲取命令結果result = stdout.read()# 關閉連接ssh.close()

（2）基于公鑰秘鑰連接

import paramikoprivate_key = paramiko.RSAKey.from_private_key_file(’/home/auto/.ssh/id_rsa’)# 創(chuàng)建SSH對象ssh = paramiko.SSHClient()# 允許連接不在know_hosts文件中的主機ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())# 連接服務器ssh.connect(hostname=’c1.salt.com’, port=22, username=’wupeiqi’, key=private_key)# 執(zhí)行命令stdin, stdout, stderr = ssh.exec_command(’df’)# 獲取命令結果result = stdout.read()# 關閉連接ssh.close()

SFTPClient:

用于連接遠程服務器并進行上傳下載功能。

（1）基于用戶名密碼上傳下載

import paramikotransport = paramiko.Transport((’hostname’,22))transport.connect(username=’GSuser’,password=’123’)sftp = paramiko.SFTPClient.from_transport(transport)# 將location.py 上傳至服務器 /tmp/test.pysftp.put(’/tmp/location.py’, ’/tmp/test.py’)# 將remove_path 下載到本地 local_pathsftp.get(’remove_path’, ’local_path’)transport.close()

（2）基于公鑰秘鑰上傳下載

import paramikoprivate_key = paramiko.RSAKey.from_private_key_file(’/home/auto/.ssh/id_rsa’)transport = paramiko.Transport((’hostname’, 22))transport.connect(username=’GSuser’, pkey=private_key )sftp = paramiko.SFTPClient.from_transport(transport)# 將location.py 上傳至服務器 /tmp/test.pysftp.put(’/tmp/location.py’, ’/tmp/test.py’)# 將remove_path 下載到本地 local_pathsftp.get(’remove_path’, ’local_path’)transport.close()

以上腳本讀取兩個參數(shù)，第一個為存放IP的文本，第二個為shell命令

執(zhí)行效果如下
