python---CMDB配置管理数据库

由 一曲冷凌霜 提交于 2019-12-27 08:30:54

前戏：项目目的

是一个运维自动化管理项目：

　　为了减少人工干预，降低人员成本
　　---资产管理
　　--操作管理

避免人员直接操作服务器，使用后台去统一操作

一：实现方式

（一）Agent基于shell命令实现（在服务器去上安装Agent，在服务器本机定时自动去获取信息，发送到数据库，然后后台获取数据进行处理）

注意：一般我们不会直接将数据直接传递到数据库，会将数据传递到API接口先进行处理，过滤，然后才会发送到数据库。

注意：数据是由服务器agent主动发送至API

 实现方案：

本地执行cmd命令。
方法一：os.system("命令")    不可以返回数据
方法二：subprocess模块，使用进程执行命令，可以获取到数据Popen("命令")，进程.stdout.read()<py2>或者直接getoutput("命令")<py3>
    def agent(self,cmd):
        import subprocess
        try:
            ret = subprocess.getoutput(cmd)
        except AttributeError:
            sub = subprocess.Popen(args=cmd,shell=True,stdout=subprocess.PIPE)
            sub.wait()
            ret = sub.stdout.read()
        return ret
python实现agent

优点：信息采集快，由服务器自己采集信息传递到API

缺点：每台服务器都必须安装Agent

 （二）SSH方法：使用paramiko模块，通过中控机服务器统一去获取指定服务器的信息。

paramiko模块了解

def ssh(self,cmd):
        import paramiko
        #1.创建SSH对象
        ssh = paramiko.SSHClient()
        #2.加上这句话不用担心选yes的问题，会自动选上
        #3.用ssh连接远程主机时，第一次连接时会提示是否继续进行远程连接，选择yes
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        ssh.connect(hostname="远程主机名",port="远程端口",username="用户名",password="密码")
        #执行命令，获取结果到标准输入\出\错误流中
        stdin,stdout,stderr = ssh.exec_command(cmd)
        #4.获取命令结果
        result = stdout.read()
        #5.关闭连接
        ssh.close()
paramiko实现远程命令执行（方法一：使用用户名，密码） 
    def ssh(self,cmd):
        import paramiko
        #1.创建SSH对象
        ssh = paramiko.SSHClient()
        #2.加上这句话不用担心选yes的问题，会自动选上
        #用ssh连接远程主机时，第一次连接时会提示是否继续进行远程连接，选择yes
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        #3.获取私钥
        private_key = paramiko.RSAKey.from_private_key_file("文件：其中保存了私钥，用于解密")
        #4.通过私钥去连接远程服务器（前提是自己的公钥已经在对方的authorized_keys文件中，paramiko已实现）
        ssh.connect(hostname="远程主机名",port="远程端口",username="用户名",pkey="私钥private_key")
        #5.执行命令，获取结果到标准输入\出\错误流中
        stdin,stdout,stderr = ssh.exec_command(cmd)
        #6.获取命令结果
        result = stdout.read()
        #7.关闭连接
        ssh.close()
        return result
paramiko使用私钥去登录远程服务器执行命令

优点：不需要为服务器安装agent等软件

缺点：速度慢，适用于服务器少得时候

 （三）saltstack：使用master对slave进行操作，基于列队实现（使用广）

# 1. 安装saltstack
#       rpm --import https://repo.saltstack.com/yum/redhat/6/x86_64/latest/SALTSTACK-GPG-KEY.pub
#
#
"""
        Master： yum install salt-master
       Master准备：
            a. 配置文件，监听本机IP
                vim /etc/salt/master
                interface: 本机IP地址
            b. 启动master
                /etc/init.d/salt-master start


        Slave：  yum install salt-minion
        Slave准备：
            a. 配置文件，连接那个master
                vim /etc/salt/minion
                master: 远程master地址
            b. 启动slave
                /etc/init.d/salt-minion start

2. 创建关系
    查看
    Master：salt-key -L
        Accepted Keys:
        Denied Keys:
        Unaccepted Keys:
            c1.com
            c2.com
            c3.com
        Rejected Keys:
    接受
    Master：salt-key -a c1.com
        Accepted Keys:
            c1.com
            c2.com
        Denied Keys:
        Unaccepted Keys:
            c3.com
        Rejected Keys:


3. 执行命令
    master：
        salt 'c1.com' cmd.run  'ifconfig'

    import salt.client
    local = salt.client.LocalClient()
    result = local.cmd('c2.salt.com', 'cmd.run', ['ifconfig'])

"""
saltstack安装 
    def salt(self,cmd):
        import subprocess
        result = subprocess.getoutput("Salt '主机名' cmd.run '"+cmd+"'")

        return result
中控机执行命令：subprocess执行salt 
    def salt(self,cmd):

        import salt.client
        local = salt.client.LocalClient()
        result = local.cmd(self.hostname,'cmd.run',[cmd])
        return result[self.hostname]
中控机执行命令：salt.client

优点：快，开发成本低

缺点：依赖saltstack

（四）使用puppet（使用ruby写的，python不易扩展）

优点：自动汇报

缺点：ruby实现

 二：代码实现（客户端）

 

bin目录（含启动文件）

from src.script import client
import os,sys

BASEDIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.append(BASEDIR)

if __name__ == "__main__":
    client()
start.py启动文件

conf目录（含配置文件）

import os

BASEDIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))


MODE = "Agent"  #SSH Salt

PLUGINS = {
    'basic':'src.plugins.basic.BasicPlugin',
    'disk':'src.plugins.disk.DiskPlugin',
    'mem': 'src.plugins.mem.MemPlugin',
    # 'nic': 'src.plugins.nic.NicPlugin',
}

# 如果采用SSH方式，则需要配置SSH的KEY和USER
SSH_PRIVATE_KEY = "/home/auto/.ssh/id_rsa"
SSH_USER = "root"
SSH_PORT = 22

# 用于API认证的KEY
KEY = '299095cc-1330-11e5-b06a-a45e60bec08b'
# 用于API认证的请求头
AUTH_KEY_NAME = 'auth-key'

ASSET_API = "http://127.0.0.1:8000/API/asset"


# Agent模式保存服务器唯一ID的文件
CERT_FILE_PATH = os.path.join(BASEDIR, 'conf', 'cert')

TEST_MODE = True
setting.py 
...
cert含有主机名信息

lib目录（含有链接库）

class BaseResponse(object):
    def __init__(self):
        self.status = True
        self.message = None
        self.data = None
        self.error = None
response.py定义一种数据格式用于在客户端传递 
import json as default_json
from .response import BaseResponse

def conv(obj):
    return obj.__dict__


class Json(object):
    @staticmethod
    def dumps(response):
        return default_json.dumps(response,default=conv)
serialize.py序列化上面的数据，将其变为可以在网络上传递的数据

log目录（记录日志）

client.py定义多种类，不同的方法与API交互 
from conf import setting
from .client import *

def client():
    if setting.MODE == 'Agent':  #"Agent"  #SSH Salt
        cli = AutoAgent()
    elif setting.MODE == "SSH":
        cli = AutoSSH()
    elif setting.MODE == "Salt":
        cli = AutoSalt()
    else:
        raise Exception("配置信息出错")
    cli.process()
script.py脚本，根据配置文件去选择实例化那种类，执行process方法获取数据

二级目录：plugins目录

from conf import setting
from lib.response import BaseResponse


def pack(hostname=None):
    response = {}

    for k,v in setting.PLUGINS.items():
        file_name,cls_name = v.rsplit('.',maxsplit=1)
        pk = __import__(file_name,fromlist=True)
        if hasattr(pk,cls_name):
            obj = getattr(pk,cls_name)()
            response[k] = obj.execute(hostname)

    return response
__init__.py定义pack方法去依次获取数据
from conf import setting

class BasePlugin(object):
    def __init__(self):
        mode_list = ['Agent','Salt','SSH']
        self.mode = setting.MODE

        pat = "command not found"
        if pat in sys_ver: #是linux...还是继续判断吧，应该不需要了
            sys_ver = self.shell_cmd("head -n 1 /etc/issue")

        if "Linux" in sys_ver:
            return self.linux()
        elif "Windows" in sys_ver:

        return ret

    def salt(self,cmd):
        import subprocess
        result = subprocess.getoutput("Salt '主机名' cmd.run '"+cmd+"'")

        return result
        # import salt.client
        # local = salt.client.LocalClient()
        # result = local.cmd(self.hostname,'cmd.run',[cmd])
        # return result[self.hostname]

    def ssh(self,cmd):
        import paramiko
        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
        private_key = paramiko.RSAKey.from_private_key_file("文件：其中保存了私钥，用于解密")
        ssh.connect(hostname="远程主机名",port="远程端口",username="用户名",pkey="私钥private_key")
        stdin,stdout,stderr = ssh.exec_command(cmd)
        result = stdout.read()

自定义js插件:实现动态获取，编辑数据

六：CMDB项目总结

1. 四种采集资产的方式（掌握3种）
    唯一标识的处理（选用主机名<人为定制规则>,因为其他的也是不具有唯一性，SN码在虚拟机上是一致的）
2. API
    API验证（时间验证，同一时间请求过滤，加密密匙）3次验证，（同加密cookie+时间限制+访问记录）
    数据库表设计
3. 后台管理
    js自定制插件（前端+后端配置），减少CURD操作
