本文主要是介绍python模块paramiko的上传下载和远程执行命令方法,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
1:连接远程linux主机并执行命令
- #!/usr/bin/env python
- import paramiko
- hostname='192.168.0.102'
- username='root'
- password='abc'
- port=22
- paramiko.util.log_to_file('paramiko.log')
- s=paramiko.SSHClient()
- s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
- s.connect(hostname = hostname,port=port,username=username, password=password)
- stdin,stdout,stderr=s.exec_command('free;df -h')
- print stdout.read()
- s.close()
执行结果如下:
- total used free shared buffers cached
- Mem: 2074940 2057420 17520 0 42416 1867968
- -/+ buffers/cache: 147036 1927904
- Swap: 2096472 240 2096232
- Filesystem Size Used Avail Use% Mounted on
- /dev/sda1 30G 12G 17G 42% /
- none 1014M 0 1014M 0% /dev/shm
- /dev/sda3 2.0G 289M 1.6G 16% /var
- /dev/sdb1 135G 14G 115G 11% /data
- /dev/sdc1 135G 127G 880M 100% /data1
- /dev/sdd1 135G 99G 30G 78% /data2
2:连接远程linux主机上传下载文件(paramiko模块是用SFTP协议来实现的)
- #!/usr/bin/env python
- import paramiko,datetime,os
- hostname='192.168.0.102'
- username='root'
- password='abc123'
- port=22
- local_dir='/tmp/'
- remote_dir='/tmp/test/'
- try:
- t=paramiko.Transport((hostname,port))
- t.connect(username=username,password=password)
- sftp=paramiko.SFTPClient.from_transport(t)
- #files=sftp.listdir(dir_path)
- files=sftp.listdir(remote_dir)
- for f in files:
- print ''
- print '#########################################'
- print 'Beginning to download file from %s %s ' % (hostname,datetime.datetime.now())
- print 'Downloading file:',os.path.join(remote_dir,f)
- sftp.get(os.path.join(remote_dir,f),os.path.join(local_dir,f))#下载
- #sftp.put(os.path.join(local_dir,f),os.path.join(remote_dir,f))#上传
- print 'Download file success %s ' % datetime.datetime.now()
- print ''
- print '##########################################'
- t.close()
- except Exception:
- print "connect error!"
执行结果:
- #########################################
- Beginning to download file from 192.168.0.102 2012-11-05 15:49:01.334686
- Downloading file: /tmp/test/wgetrc Download file success 2012-11-05 15:49:05.955184
