1、代码
import paramiko
# 创建对象
client = paramiko.SSHClient()
# 进行验证，填写yes
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect("172.27.236.108", 22, "root", "1")
# stdin 标准输入
# stdout 标准输出
# stderr 错误信息
stdin, stdout, stderr = client.exec_command("whoami")
print(stdout.read())
2、输出
报错关键字：
- paramiko
- Exception ignored in: <function BufferedFile.del at 0x03A9D898>
- AttributeError: ‘NoneType’ object has no attribute ‘time’
b'root\n'
Exception ignored in: <function BufferedFile.__del__ at 0x03A9D898>

3、解决办法
ssh返回的结果缓冲释放过快，未读完，就产生报错了。
加一个sleep 1秒就可以解决。
import paramiko
import time
# 创建对象
client = paramiko.SSHClient()
# 进行验证，填写yes
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect("172.27.236.108", 22, "root", "1")
# stdin 标准输入
# stdout 标准输出
# stderr 错误信息
stdin, stdout, stderr = client.exec_command("whoami")
print(stdout.read())
time.sleep(1)
