python使用paramiko执行服务器脚本并拿到实时结果

这篇文章主要介绍了python使用paramiko执行服务器脚本并拿到实时结果，具有很好的参考价值，希望对大家有所帮助。

paramiko 执行服务器脚本并拿到实时结果

import paramiko

cmd = '{0}/{1} linux 32'.format('/root/installer', 'make_client_installer.sh')
print(cmd)
try:
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('xx.xx.xx.xx', port, 'username', 'password', timeout=5)
stdin, stdout, stderr = ssh.exec_command(cmd, get_pty=True)
while not stdout.channel.exit_status_ready():
result = stdout.readline()
print(result)
if stdout.channel.exit_status_ready():
a = stdout.readlines()
print(a)
break
ssh.close()
except Exception as e:
print(e)```

python paramiko模块使用

paramiko远程密码连接

# 基于ssh用于连接远程服务器做操作:远程执行命令， 上传文件， 下载文件
import  paramiko

# ssh root@172.25.254.250
# 创建一个ssh对象;
client = paramiko.SSHClient()

# 2. 解决问题:如果之前没有；连接过的ip, 会出现
# Are you sure you want to continue connecting (yes/no)? yes
# 自动选择yes
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

# 3. 连接服务器
client.connect(hostname='172.25.254.1',
   port=22,
   username='root',
   password='redhat')
# 4. 执行操作
stdin, stdout, stderr = client.exec_command('hostnaewdeme')


# 5. 获取命令的执行结果;
result = stdout.read().decode('utf-8')
print(result)

print(stderr.read())

# 6. 关闭连接
client.close()

paramiko批量远程密码连接

# 基于ssh用于连接远程服务器做操作:远程执行命令， 上传文件， 下载文件
import  paramiko
import  logging

from paramiko.ssh_exception import NoValidConnectionsError, AuthenticationException
def connect(cmd, hostname, port=22, username='root', password='westos'):
# ssh root@172.25.254.250
# 创建一个ssh对象;
client = paramiko.SSHClient()

# 2. 解决问题:如果之前没有；连接过的ip, 会出现
# Are you sure you want to continue connecting (yes/no)? yes
# 自动选择yes
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())

try:
# 3. 连接服务器
client.connect(hostname=hostname,
   port=port,
   username=username,
   password=password)

print("正在连接主机%s......." %(hostname))
except NoValidConnectionsError as e:
print("连接失败")
except AuthenticationException as e:
print("密码错误")
else:
# 4. 执行操作
stdin, stdout, stderr = client.exec_command(cmd)

# 5. 获取命令的执行结果;
result = stdout.read().decode('utf-8')
print(result)

# 6. 关闭连接
client.close()

with open('host.txt') as f:
for line in f:
line = line.strip()
hostname, port, username, password = line.split(':')
print(hostname.center(50, '*'))
connect('hostname', hostname, port, username, password)

paramiko基于公钥密钥连接

# 基于ssh用于连接远程服务器做操作:远程执行命令， 上传文件， 下载文件
import  paramiko
from paramiko.ssh_exception import NoValidConnectionsError, AuthenticationException


def connect(cmd, hostname, port=22, user='root'):
# ssh root@172.25.254.250
# 创建一个ssh对象;
client = paramiko.SSHClient()

# 返回一个私钥对象
private_key = paramiko.RSAKey.from_private_key_file('id_rsa')


# 2. 解决问题:如果之前没有；连接过的ip, 会出现
# Are you sure you want to continue connecting (yes/no)? yes
# 自动选择yes
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
try:
# 3. 连接服务器
client.connect(hostname=hostname,
   port=port,
   username=user,
   pkey=private_key
  )
# 4. 执行操作
stdin, stdout, stderr = client.exec_command(cmd)
except NoValidConnectionsError as e:
print("连接失败")
except AuthenticationException as e:
print("密码错误")
else:
# 5. 获取命令的执行结果;
result = stdout.read().decode('utf-8')
print(result)
finally:
# 6. 关闭连接
client.close()


for count in range(254):
host = '172.25.254.%s' %(count+1)
print(host.center(50, '*'))
connect('uname', host)

基于用户名密码上传下载

import  paramiko
transport = paramiko.Transport(('172.25.254.39', 22))
transport.connect(username='root', password='westos')
sftp = paramiko.SFTPClient.from_transport(transport)
# 上传文件, 包含文件名
sftp.put('/tmp/kiosk', '/mnt/kiosk1')
sftp.get('/mnt/kiosk', '/home/kiosk/Desktop/day18/kiosk')
transport.close()

基于密钥上传下载

import  paramiko
# 返回一个私钥对象
private_key = paramiko.RSAKey.from_private_key_file('id_rsa')
transport = paramiko.Transport(('172.25.254.39', 22))
transport.connect(username='root',pkey=private_key)
sftp = paramiko.SFTPClient.from_transport(transport)
# 上传文件, 包含文件名
sftp.put('/tmp/kiosk', '/mnt/kiosk2')
sftp.get('/mnt/kiosk2', '/home/kiosk/Desktop/day18/kiosk')
transport.close()
