Python 13:程序:堡垒机开发


1、需求

2、表结构

3、readme

4、目录结构

5、代码

6、测试样图 


一、需求

功能需求:

1、所有的用户操作日志要保留在数据库中(先存到redis中防止数据断线丢失)
2、每个用户登录堡垒机后,只需要选择具体要访问的设置,就连接上了,不需要再输入目标机器的访问密码
3、允许用户对不同的目标设备有不同的访问权限,例:
  1、对192.168.1.113有mysql 用户的权限
  2、对192.168.1.105有root用户的权限
  3、对192.168.1.100没任何权限
4、分组管理,即可以对设置进行分组,允许用户访问某组机器,但对组里的不同机器依然有不同的访问权限 

二、表结构

三、readme

 5 程序介绍
 6 1、所有的用户操作日志要保留在数据库中(先存到redis中防止数据断线丢失)
 7 2、每个用户登录堡垒机后,只需要选择具体要访问的设置,就连接上了,不需要再输入目标机器的访问密码
 8 3、允许用户对不同的目标设备有不同的访问权限,例:
 9   1、对192.168.1.113有mysql 用户的权限
10   2、对192.168.1.105有root用户的权限
11   3、对192.168.1.100没任何权限
12 4、分组管理,即可以对设置进行分组,允许用户访问某组机器,但对组里的不同机器依然有不同的访问权限

四、目录结构

五、代码

7 if __name__ == '__main__':
8     from modules.actions import excute_from_command_line
9     excute_from_command_line(sys.argv)
run.py

2、conf

六、测试样图

1、创建表结构

2、添加数据

 

3、登陆操作

4、命令审计

a、root用户(审计所有用户)

b、个人用户(审计当前用户操作命令)
