15     def connect(self):
16         while True:
17             try:
18                 self.s = paramiko.SSHClient()

23             except Exception as e:
24                 print self.connip, e
25 ###关闭连接
26     def sshclose(self):
27         self.s.close()
28 
29 ###在远程服务器执行命令,无输出
30     def execcommand(self, cmd):
31         self.s.exec_command(cmd)
32 
33 ###在远程服务器执行命令并且输出结果
34     def exec_log(self, cmd):
35         stdin, stdout, stderr = self.s.exec_command(cmd)
36         print self.connip, stdout.read().decode(), stderr.read()

39 ###上传文件到远程服务器
40     def trans(self, fromfile, tofile):
41         if os.path.exists(fromfile)  == True:
42             try:

44                 self.t.connect(username=self.connuser, password=self.connpass)
45                 self.sftp = paramiko.SFTPClient.from_transport(self.t)
46                 self.sftp.put((fromfile), (tofile), confirm=True)
47                 self.t.close()
48             except Exception as e:

52     def transclose(self):
53         self.t.close()

57 ###通过root账号和密码连接Linux服务器，IP和密码通过中文字符“￥”区分

60     def rootConn(rootfile,cmd):
61         with open(rootfile, 'r') as f:
62             result = dict(line.strip().split('￥') for line in f if line)
63             for v, k in result.items():
64 #                print v,k
65                 host = ConnLinux(v, "root", k)
66                 host.connect()
67                 host.execcommand(cmd)
68                 host.sshclose()
