用Python实现远程登陆主机执行命令或通过sftp上传下载文件,有个很好的模块paramiko模块来演示这些功能,使用起来很方便,大家可学习一下。写了几个小程序,用于说明此模块的使用方法。 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: 20749402057420175200424161867968 -/+ buffers/cache: 1470361927904 Swap: 20964722402096232 Filesystem Size Used Avail Use% Mounted on /dev/sda1 30G12G17G42% / none 1014M01014M0% /dev/shm /dev/sda3 2.0G289M1.6G16% /var /dev/sdb1 135G14G115G11% /data /dev/sdc1 135G127G880M100% /data1 /dev/sdd1 135G99G30G78% /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 from192.168.0.1022012-11-0515:49:01.334686 Downloading file: /tmp/test/wgetrc Download file success 2012-11-0515:49:05.955184 ########################################## ######################################### Beginning to download file from192.168.0.1022012-11-0515:49:05.955342 Downloading file: /tmp/test/xinetd.conf Download file success 2012-11-0515:49:10.929568 ########################################## ######################################### Beginning to download file from192.168.0.1022012-11-0515:49:10.929740 Downloading file: /tmp/test/warnquota.conf Download file success 2011-12-0515:49:14.213570 ########################################## ![]() (编辑:PHP编程网 - 黄冈站长网) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
