用paramiko远程监控,下载，上传服务器

• 安装paramiko
• 代码如下

import paramiko
import paramiko
server_ip = '192.168.1.1'
server_user = 'root'
server_passwd = ''
server_port = 22
ssh = paramiko.SSHClient()
def ssh_connect():
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.load_system_host_keys()
    ssh.connect(server_ip, server_port,server_user, server_passwd)
    return ssh
def client_connect():
    client = paramiko.Transport((server_ip, server_port))
    client.connect(username = server_user, password = server_passwd)
    return client
def ssh_disconnect(client):
    client.close()

def exec_cmd(command, ssh):
    '''
    windows客户端远程执行linux服务器上命令
    '''
    stdin, stdout, stderr = ssh.exec_command(command)
    err = stderr.readline()
    out = stdout.readline()
    print(stdout.read())

def win_to_linux(localpath, remotepath,client):
    '''
    windows向linux服务器上传文件.
    localpath  为本地文件的绝对路径。如：D:  est.py
    remotepath 为服务器端存放上传文件的绝对路径,而不是一个目录。如：/tmp/my_file.txt
    '''

    sftp = paramiko.SFTPClient.from_transport(client)
    sftp.put(localpath,remotepath)
    client.close()

def linux_to_win(localpath, remotepath,client):
    '''
    从linux服务器下载文件到本地
    localpath  为本地文件的绝对路径。如：D:  est.py
    remotepath 为服务器端存放上传文件的绝对路径,而不是一个目录。如：/tmp/my_file.txt
    '''
    sftp = paramiko.SFTPClient.from_transport(client)
    sftp.get(remotepath, localpath)
    client.close()

class AllowAllKeys(paramiko.MissingHostKeyPolicy):
   def missing_host_key(self, client, hostname, key):
       return

def muit_exec_cmd(ssh,cmd):
    '''
    ssh ssh连接
    cmd 多命名
    '''
    ssh.set_missing_host_key_policy(AllowAllKeys())
    channel = ssh.invoke_shell()
    stdin = channel.makefile('wb')
    stdout = channel.makefile('rb')

    stdin.write(cmd)
    print(stdout.read())

    stdout.close()
    stdin.close()

cl = client_connect()
sh = ssh_connect()
muit_exec_cmd(sh,'''
    cd ~
    ls
    sar
    exit
    ''')
win_to_linux("t.txt","/data/t1.txt",cl)
cl.close()
sh.close()
