python远程ssh

1. python远程执行命令

#!/usr/bin/python
# -*- coding: utf-8 -*-
import paramiko
# from cryptography.hazmat.backends import default_backend
import time


def excuseRemoteCmd(ipaddr, port, username, pwd, cmd):
    print(ipaddr, port, username, pwd, cmd)
    try:
        # 创建SSH对象
        ssh = paramiko.SSHClient()

        # 允许连接不在know_hosts文件中的主机
        ssh.load_system_host_keys()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

        # 连接服务器
        ssh.connect(ipaddr, port=port, username=username,
                    password=pwd, timeout=10)

        # 打开一个Channel并执行命令
        # stdout 为正确输出，stderr为错误输出，同时是有1个变量有值
        stdin, stdout, stderr = ssh.exec_command(cmd, get_pty=True, timeout=60)
        # 打印执行结果
        # for item in stdout.readlines():
        #     print item
        while not stdout.channel.exit_status_ready():
            result = stdout.readline()
            print(result)
            if stdout.channel.exit_status_ready():
                result = stdout.readlines()
                print(result)
                break
        # 错误打印
        err_list = stderr.readlines()
        if len(err_list) > 0:
            print 'ERROR:' + err_list
            # exit()

        # 关闭连接
        ssh.close()
        return stdout, stderr
    except Exception as e:
        print(e)
    return stdout, stderr

2. shell远程执行命令

# 远程执行脚本
CardCmd = "ssh -T -o ServerAliveInterval=5 -p %s %s@%s  "sh /opt/xxx/sed_network_card.sh %s"" % (
        remotePort, username, remoteIp, remoteIp)
    print("getNetCardCmd:%s" % (CardCmd))
    status, output = commands.getstatusoutput(CardCmd)
    if status != 0:
        print("cmd result:%s,status:%s" % (output, status))
        return status, output
 ----------------------------------------------------------------------------
 # 远程拷贝
 Cmd = "scp " + " -P " + remotePort + " " + SrcPath + 
        " "+username+"@"+remoteIp+":" + DstPath
    print("Cmd:", Cmd)
    status, output = commands.getstatusoutput(Cmd)
    if status != 0:
        print("cmd result:%s,status:%s" % (output, status))
        return status, output
