paramiko安装

Paramiko is a Python (2.7, 3.4+) implementation of the SSHv2 protocol.

error: command ‘x86_64-linux-gnu-gcc’ failed with exit status 1

解决办法：sudo apt-get install build-essential libssl-dev libffi-dev python-dev

再不行就更新, 就不信安不上, pip install --upgrade setuptools

批量执行: 

import paramiko

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('192.168.189.900', 22, 'yangxl', '123456')
stdin, stdout, stderr = ssh.exec_command('ifconfig')
print(stdout.read().decode('utf-8'))
ssh.close()

上传、下载文件:

import paramiko

ssh = paramiko.Transport(('192.168.189.128', 22))
ssh.connect(username='yangxl', password='123456')
sftp = paramiko.SFTPClient.from_transport(ssh)
# sftp.put('/home/yangxl/test.py', '/tmp/test2.py')  # 上传
sftp.put('/tmp/tmpaddon', '/home/yangxl/test3.py')  # 下载
ssh.close()

pip安装没有demo哦, 

执行 `python demo.py` 就能登陆机器,

        while True:
            r, w, e = select.select([chan, sys.stdin], [], [])
            if chan in r:
                try:
                    x = u(chan.recv(1024))
                    if len(x) == 0:
                        sys.stdout.write("
*** EOF
")
                        break
                    sys.stdout.write(x)  # 输出到标准输出
                    sys.stdout.flush()  # 刷新到屏幕
                except socket.timeout:
                    pass
            if sys.stdin in r:
                x = sys.stdin.read(1)  # 读入到标准输入, (稍后发送)
                if len(x) == 0:
                    break
                chan.send(x)
