python利用paramiko執行伺服器命令

話不多說直接上**

封裝連線

@staticmethod

defconnect(ip, server_user, server_port, server_path):
"""連線伺服器
:param :
:return:
"""ssh =paramiko.sshclient()
private_key = paramiko.rsakey.from_private_key_file('
{}.ssh/id_rsa
'.format(server_path))
ssh.set_missing_host_key_policy(paramiko.autoaddpolicy())
try:
ssh.connect(ip, port=server_port, username=server_user, pkey=private_key, timeout=5, allow_agent=true)
return
ssh        
except
exception as e:
'connect_error info is {}
'.format(e.__repr__
()))
return

在伺服器執行命令

def

fabric_run_cmd(self, ip, server_user, server_port, server_path, cmd):
"""批量在伺服器執行命令
:return:
"""conn =self.connect(ip, server_user, server_port, server_path)
try:
if type(conn) ==dict:
return
conn
else
:                stdin, stdout, stderr =conn.exec_command(cmd)
'fabric_run_cmd_stdout info is {}
'.format(stdout.readlines()))
'fabric_run_cmd_stderr info is {}
'.format(stderr.readlines()))
channel =stdout.channel
status =channel.recv_exit_status()
conn.close()
'fabric_run_cmd_status info is {}
'.format(status))
if status ==0:
return
else
:                    
return
except
exception as e:
'fabric_run_cmd_error info is {}
'.format(e.__repr__
()))
return

將檔案傳送到伺服器

def

fabric_put_file(self, ip, src_file, dst_file, server_user, server_port, server_path):
"""傳送檔案到伺服器
:return:
"""conn =self.connect(ip, server_user, server_port, server_path)
if type(conn) ==dict:
return
conn
else
:            
try:
ftp =conn.open_sftp()
ftp.put(dst_file, src_file)  
#傳送檔案之前先判斷有沒有目標資料夾  如果沒有現在伺服器上建立資料夾
ftp.close()  #
在此判斷檔案是否傳送成功
return
except
exception as e:
'fabric_put_file_error info is {}
'.format(e.__repr__
()))
return
