Python的paramiko，实现ssh

import paramiko
import ConfigParser

class ParamikoClient:
    def __init__(self,config_str):
        self.config = ConfigParser.ConfigParser()
        self.config.read(config_str)

        self.client = paramiko.SSHClient()
        self.client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    def connet(self):

        try:
            self.client.connect(hostname=self.config.get(‘ssh‘,‘host‘),port=self.config.getint(‘ssh‘,‘port‘),username=self.config.get(‘ssh‘,‘username‘),password=self.config.get(‘ssh‘,‘password‘))
        except Exception,e:
            print e
            try:
                self.client.close()
            except:
                pass
    def run_cmd(self,cmd_str):
            stdin, stdout, stderr = self.client.exec_command(cmd_str)
            print stdout.read()

client = ParamikoClient(‘config.ini‘)
client.connet()
client.run_cmd(‘date‘)

[ssh]
host = 192.168.1.101
port = 22
username = root
password = 123456
