python---堡垒机开发

 一：堡垒机需求分析

注意：

虽然我们在中间使用防火墙服务器对流量进行拦截和转发也可以起到过滤作用，但是我们无法去获取到完整，正确的操作记录。因为无论是客户端还是服务器端（管理员可能会去修改记录，而且可能会出现一个账号多人用，无法知道是谁操作了这台服务器）我们都无法完全控制。所以，我们可以使用中间件，替客户去执行命令，并且记录操作记录到堡垒机的数据库中

history        可以查看操作记录
history -c     清空记录

注意：

由于所有密码都存在堡垒机中，所以我们要保证其环境的安全性，，最好还有一个备份堡垒机

补充：远程登录服务器的方法

（1）账号+密码

（2）A将公钥放在对方B服务器，A就可以直接登录B服务器

公钥登录方法测试：

1.在本机生成密匙，公钥（后缀.pub）和私钥

2.将公钥远程拷贝或发生到对方服务器

 

 

3.要想公钥在对方服务器生效，需要将发送过来的公钥放在用户家目录下的.ssh隐藏目录，若是不存在该目录，需要先生成该目录，然后再加文件拷贝进入

4.将公钥在对方服务器中放入用户的家目录下的.ssh目录，并修改名为authorized_keys,才能生效

5.测试远程ssh登录

 二：数据表结构设计

from django.db import models
from django.contrib.auth.models import (
    BaseUserManager, AbstractBaseUser,PermissionsMixin
)

#主机表：含有主机名，ip地址，端口，外联IDC机房
class Host(models.Model):
    name = models.CharField(max_length=64,unique=True)
    ip_addr = models.GenericIPAddressField(unique=True)
    port = models.SmallIntegerField(default=22)
    idc = models.ForeignKey("IDC")

    def __str__(self):
        return self.name

#用户表，用于登录上面主机，若是只有用户密码，那么是一对多，但是包含公钥登录，所以结构变为多对多，第三张表我们需要自己去创建
class RemoteUser(models.Model):
    '''远程登录用户:1.私钥，秘钥，2.用户密码'''
    auth_type_choices = (
        (0,"ssh-password"),
        (1,"ssh-key"),
    )

    auth_type = models.SmallIntegerField(choices=auth_type_choices)

    username = models.CharField(max_length=32)

    password = models.CharField(max_length=64,blank=True,null=True)

    class Meta:
        unique_together = ("auth_type","username","password")

    def __str__(self):
        return "%s:%s"%(self.username,self.password)

#主机对用户的多对多，第三张表，用于和堡垒机的账号表多对多关联。也会和主机组多对多关联
class HostToRemoteUser(models.Model):
    host = models.ForeignKey("Host")
    remote_user = models.ForeignKey("RemoteUser")

    class Meta:
        unique_together = ("host","remote_user")

    def __str__(self):
        return "%s %s"%(self.host,self.remote_user)

#主机组，类似于角色分组。对各个主机进行分组管理
class HostGroup(models.Model):
    """存储主机组"""
    name = models.CharField(max_length=64,unique=True)
    #hosts = models.ManyToManyField("Host")
    host_to_remote_users = models.ManyToManyField("HostToRemoteUser")

    def __str__(self):
        return self.name

#堡垒机的账号管理，包括了权限管理
class UserProfileManager(BaseUserManager):
    def create_user(self, email, name, password=None):
        """
        Creates and saves a User with the given email, date of
        birth and password.
        """
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
            name=name,
        )

        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, name, password):
        """
        Creates and saves a superuser with the given email, date of
        birth and password.
        """
        user = self.create_user(
            email,
            password=password,
            name=name,
        )
        user.is_superuser = True
        user.save(using=self._db)
        return user

#账号管理，关联主机分为单个主机用户表HostToRemoteUser（主要是对某些用户的分配主机只有一台或者过少，不需要分配主机用户组），和主机用户组HostGroup
class UserProfile(AbstractBaseUser,PermissionsMixin):
    """堡垒机账号"""
    email = models.EmailField(
        verbose_name='email address',
        max_length=255,
        unique=True,

    )
    name = models.CharField(max_length=64, verbose_name="姓名")
    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=True)
    objects = UserProfileManager()

    host_to_remote_users = models.ManyToManyField("HostToRemoteUser",blank=True,null=True)
    host_groups = models.ManyToManyField("HostGroup",blank=True,null=True)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['name']

    def get_full_name(self):
        # The user is identified by their email address
        return self.email

    def get_short_name(self):
        # The user is identified by their email address
        return self.email

    def __str__(self):              # __unicode__ on Python 2
        return self.email

 完善操作记录表

class AuditLog(models.Model):
    '''日志记录'''
    user = models.ForeignKey("UserProfile",verbose_name="堡垒机账号",blank=True,null=True)
    host_to_remote_user = models.ForeignKey("HostToRemoteUser",verbose_name="主机账号",blank=True,null=True)
    log_type_choices = (
        (0,"login"),
        (1,"cmd"),
        (2,"logout")
    )
    log_type = models.SmallIntegerField(choices=log_type_choices,default=0)
    content = models.CharField(max_length=255,blank=True,null=True)
    datetime = models.DateTimeField(auto_now_add=True,blank=True,null=True)

    def __str__(self):
        return "%s %s %s"%(self.user,self.host_to_remote_user,self.content)

 三：业务调用

（1）backend_manage.py:配置Django环境，便于使用

    django.setup()

    finally:
        termios.tcsetattr(sys.stdin, termios.TCSADRAIN, oldtty)


# thanks to Mike Looijmans for this code
def windows_shell(chan):　　#windows使用多线程和socket方式交互
    import threading

    sys.stdout.write(

四：linux服务器上测试

（1）为项目创建一个公共用户，为堡垒机用户提供。密码设置简单

useradd crazyeye
passwd crazyeye
输入密码：123456

（2）正常启用项目

python backend_manage.py run

（3）需要用户登录账号后立即执行程序，减少用户权限

去操作用户家目录下的.bashrc文件，进行配置

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

# User specific aliases and functions
python3 /home/crazyeye/crazyeye/backend_manage.py run　　#用户登录后自动执行
exit　　#防止用户出现不可预期的错误导致上面的程序退出，而去操作账号下的其他数据，我们需要让上面程序结束后，账号退出即可

 五.实现web页面对堡垒机进行操作

linux下安装shellinabox实现web登录服务器

{% extends "index.html" %}
{% block right-content-container %}
           <!--Page Title-->
                <!--~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~-->
                <div id="page-title">
                    <h1 class="page-header text-overflow">Web Ssh</h1>

                    <!--Searchbox-->
                    <div class="searchbox">
                        <div class="input-group custom-search-form">
                            <input type="text" class="form-control" placeholder="Search..">
                            <span class="input-group-btn">
                                <button class="text-muted" type="button"><i class="demo-pli-magnifi-glass"></i></button>
                            </span>
                        </div>
                    </div>
                </div>
                <!--~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~-->
                <!--End page title-->

                <!--Page content-->
                <!--===================================================-->
                <div id="page-content">
                    <div class="row">
                        <div class="col-lg-12">
                             <iframe src="http://192.168.218.129:4200/" width="100%" style="padding-bottom:100%;background-color:white;"></iframe>
                        </div>
                    </div>
                </div>
                <!--===================================================-->
                <!--End page content-->
{% endblock %}

六.实现批量命令和文件功能

（0）添加数据表和业务流程图

1..数据表增加

class Task(models.Model):
    '''批量任务'''
    task_type_choice = (
        ('cmd',"批量命令"),
        ('file_transfer','文件传输'),
    )

    task_type = models.CharField(choices=task_type_choice,max_length=32)
    user = models.ForeignKey("UserProfile")
    content = models.CharField(max_length=255)

    date = models.DateTimeField(auto_now_add=True)
    def __str__(self):
        return "%s %s"%(self.task_type,self.content)

class TaskLogDetail(models.Model):
    '''存储每台主机执行结果'''
    task = models.ForeignKey("Task")
    host_to_remote_user = models.ForeignKey("HostToRemoteUser")
    result = models.TextField(verbose_name="任务结果")

    status_choices = ((0, 'initialized'), (1, 'sucess'), (2, 'failed'), (3, 'timeout'))
    status = models.SmallIntegerField(choices=status_choices)

    date = models.DateTimeField(auto_now_add=True)

2.流程图

（1）批量命令展示

（2）批量文件操作展示

 （3）全部代码展示

1.公共组件

<div class="col-lg-3">
                            <div class="panel">
                                <div class="panel-heading">
