python的paramiko模块

paramiko模块基于ssh，用于连接远程服务器并执行相关操作。

sshclient：用于连接远程服务器并执行基本命令：

import paramiko

# 创建ssh对象
ssh = paramiko.SSHClient()
# 允许连接不在know_hosts文件中的主机
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 连接服务器
ssh.connect(hostname='192.168.254.130', port=22, username='root',
            password='123456')
# 执行命令
stdin, stdout, stderr = ssh.exec_command('service iptables stop')
# 获取命令执行结果
result = stdout.read()
print(result.decode())
# 关闭连接
ssh.close()

 

import paramiko

transport = paramiko.Transport(('192.168.254.129', 22))
transport.connect(username='root', password='123456')

ssh = paramiko.SSHClient()
ssh._transport = transport

stdin, stdout, stderr = ssh.exec_command('df;ls')
res, err = stdout.read(), stderr.read()
reslt = res if res else err
print(reslt.decode())
ssh.close()

import paramiko
trans = paramiko.Transport(('192.168.33.128', 22))
trans.connect(username='root', password='123456')

sftp = paramiko.SFTPClient.from_transport(trans)
sftp.put('test', '/tmp/test')     #第一个参数是上传的文件及路径，第二个参数是服务器的路径及名称
sftp.get('/root/test/ftptest', 'p')      #第一个是下载的路径及名称，第二个参数是本地的路径及名称
trans.close()

import paramiko
 
private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
 
# 创建SSH对象
ssh = paramiko.SSHClient()
# 允许连接不在know_hosts文件中的主机
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 连接服务器
ssh.connect(hostname='c1.salt.com', port=22, username='wupeiqi', key=private_key)
 
# 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
# 获取命令结果
result = stdout.read()
 
# 关闭连接
ssh.close()
