Ssh连接部分：

import paramiko
import json
'''
ssh 连接对象
本对象提供密钥连接、命令执行、关闭连接
'''class Sshclass(object):# ip = ''# port = 22# username = ''# timeout = 0# ssh = Nonedef __init__(self,ip,username,port=22,timeout=30):'''初始化ssh对象:param ip: 主机IP:param username: 登录用户名:param port: ssh端口号:param timeout: 连接超时:return:'''self.ip = ipself.username = usernameself.timeout = timeoutself.port = port'''SSHClient作用类似于Linux的ssh命令，是对SSH会话的封装，该类封装了传输(Transport)，通道(Channel)及SFTPClient建立的方法(open_sftp)，通常用于执行远程命令。Paramiko中的几个基础名词：1、Channel：是一种类Socket，一种安全的SSH传输通道；2、Transport：是一种加密的会话，使用时会同步创建了一个加密的Tunnels(通道)，这个Tunnels叫做Channel；3、Session：是client与Server保持连接的对象，用connect()/start_client()/start_server()开始会话。'''ssh = paramiko.SSHClient()#远程主机没有本地主机密钥或HostKeys对象时的连接方法，需要配置ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())self.ssh = sshdef conn_by_key(self,key):'''密钥连接:param key:  str rsa密钥路径:return:  ssh连接对象'''rsa_key = paramiko.RSAKey.from_private_key(key)self.ssh.connect(hostname=self.ip,port=self.port,username=self.username,pkey=rsa_key,timeout=self.timeout)if self.ssh:print('密钥连接成功')else:self.close()raise Exception('密钥连接失败')def conn_by_pwd(self,pwd):'''密码连接:param pwd: 登录密码:return:  ssh连接对象'''self.ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())self.ssh.connect(hostname=self.ip,port=self.port,username=self.username,password=pwd)if self.ssh:print('密码连接成功')else:self.close()raise Exception('密码连接失败')def exec_commond(self,command):'''命令控制:param commond: 命令:return: 返回结构'''if command:stdin, stdout, stderr = self.ssh.exec_command(command)return {"stdin":command,"stdout":stdout.read(),"stderr":stderr.read()}else:self.close()raise Exception("命令不能为空")def close(self):'''关闭当前连接:return:'''if self.ssh:self.ssh.close()else:raise Exception("ssh关闭连接失败，当前对象没有ssh连接。")def upload_file(self,local_path,remote_path,file_name):# sftp_link = paramiko.Transport(self.ip,self.port)# sftp_link.connect(username=self.username,password=pwd)# sftp = paramiko.SFTPClient.from_transport(sftp_link)sftp = self.ssh.open_sftp()try:sftp.put(local_path+"\\"+file_name, remote_path+"/"+file_name)#print("上传成功")return ("上传成功"), 200except Exception as e:return {'error': '上传失败'}, 888finally:sftp.close()self.close()if __name__ == '__main__':ssh = Sshclass('192.168.115.23','root', port=22)pwd = "123456"local_path = 'D:\PyChrom\Python_Flask\自动化接口--Flask'remote_path = "/opt"file_name = 'file.py'ssh.conn_by_pwd(pwd)#res = str(ssh.exec_commond("ls /"))#print(res)res = ssh.upload_file(local_path,remote_path,file_name)print(res)

接口调试

后续优化思路：

目前只是远程连接+文件上传，后续会继续优化

弄个公共的nfs，平常一些脚本和包会放到这个nfs里，脚本或包自动从nfs里拉，然后执行脚本，即可部署，包括多机部署。
