python连接linux

使用python paramiko库，直接用pip安装pip install paramiko

其简单用法如下代码：

import paramiko

class SSH(object):
	def __init__(self, host, port, user, passwd):
		self.host = host
		self.port = port
		self.user = user
		self.passwd = passwd
		self.length = 0
		self.ssh = paramiko.SSHClient()
		self.ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
		try:
			self.ssh.connect(self.host,self.port,self.user,self.passwd)
		except Exception as e:
			print ('Exception:', e)
	def Execmd(self,exe_cmd):
		stdin, stdout, stderr = self.ssh.exec_command(exe_cmd, get_pty = True)
		return stdout.read()
if __name__ == '__main__':
	ssh = SSH(yourip, '22', youruser, yourpasswd)
	ss = ssh.Execmd('cd ~;pwd')
	print(ss)

其结果就会打印出你linux服务器home的目录即：b’/home\r\n’
