一 CMDB简介
1.1 什么是CMDB？
CMDB（资产管理系统）是所有运维工具的数据基础
1.2 CMDB包含的功能
用户管理，记录测试，开发，运维人员的用户表
业务线管理，需要记录业务的详情
项目管理，指定此项目用属于哪条业务线，以及项目详情
应用管理，指定此应用的开发人员，属于哪个项目，和代码地址，部署目录，部署集群，依赖的应用，软件等信息
主机管理，包括云主机，物理机，主机属于哪个集群，运行着哪些软件，主机管理员，连接哪些网络设备，云主机的资源池，存储等相关信息
主机变更管理，主机的一些信息变更，例如管理员，所属集群等信息更改，连接的网络变更等
网络设备管理，主要记录网络设备的详细信息，及网络设备连接的上级设备
IP管理，IP属于哪个主机，哪个网段, 是否被占用等
1.3 实现的四种方式
1.3.1 Agent实现方式
Agent方式，可以将服务器上面的Agent程序作定时任务，定时将资产信息提交到指定API录入数据库
其本质上就是在各个服务器上执行
subprocess.getoutput()命令，然后将每台机器上执行的结果，返回给主机API，然后主机API收到这些数据之后，放入到数据库中，最终通过web界面展现给用户
#linux
import subprocess
import re
res = subprocess.getoutput("ifconfig")
print(res)
ip=re.findall('inet (.*?) netmask',res)
print(ip)
# windows
import subprocess
import re
res=subprocess.getoutput('ipconfig')
print(res)
ip=re.findall('IPv4 地址 . . . . . . . . . . . . : (.*)',res)
print(ip)
优点：速度快
缺点：需要为每台服务器部署一个Agent程序
使用crontab定时执行python脚本
# 1 进入创建crontab定时任务
crontab -e
# 2 写入任务（每分钟执行一次test.py）
* * * * * python3 test.py
# 3 编写test.py
with open('a.txt','a') as f:
f.write('hello world')
# 4 查看定时任务
crontab -l
1.3.2 ssh实现方式 （基于Paramiko模块）
中控机通过Paramiko（py模块）登录到各个服务器上，然后执行命令的方式去获取各个服务器上的信息
优点：无Agent
缺点：速度慢
如果在服务器较少的情况下，可应用此方法
import paramiko
import re
#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='101.133.225.166',port=22,username='root',password='')
# 执行命令
stdin,stdout,stderr = ssh.exec_command('ifconfig')
# 获取命令结果
result = stdout.read().decode('utf-8')
print(result)
ip=re.findall('inet (.*?) netmask',result)
print(ip)
# 关闭连接
ssh.close()
1.3.3 saltstack方式
此方案本质上和第二种方案大致是差不多的流程，中控机发送命令给服务器执行。服务器将结果放入另一个队列中，中控机获取将服务信息发送到API进而录入数据库。
执行流程:
第一步: 由管理员录入资产(主机名,SN等信息),通过后台管理,录入数据库
第二步: salt-master从数据库获取未采集资产信息的服务器
第三步: salt-master发送命令给salt-minion执行
第四步: salt-master拿到执行结果
第五步: 将结果发送给API
第六步: API将其写入数据库解释:
salt-master可以理解为主人
salt-minion可以理解为奴隶
优点：快，开发成本低
缺点：依赖于第三方工具
salstack的安装和配置
1.安装和配置
master端：
"""
1. 安装salt-master
yum install salt-master
2. 修改配置文件：/etc/salt/master
interface: 0.0.0.0 # 表示Master的IP
3. 启动
service salt-master start
"""
slave端：
"""
1. 安装salt-minion
yum install salt-minion
2. 修改配置文件 /etc/salt/minion
master: 10.211.55.4 # master的地址
或
master:
- 10.211.55.4
- 10.211.55.5
random_master: True
id: c2.salt.com # 客户端在salt-master中显示的唯一ID
3. 启动
service salt-minion start
2.授权
salt-key -L # 查看已授权和未授权的slave
salt-key -a salve_id # 接受指定id的salve
salt-key -r salve_id # 拒绝指定id的salve
salt-key -d salve_id # 删除指定id的salve
3.执行命令
在master服务器上对salve进行远程操作
salt 'c2.salt.com' cmd.run 'ifconfig'
# 基于API的方式
import salt.client
local = salt.client.LocalClient()
result = local.cmd('c2.salt.com', 'cmd.run', ['ifconfig'])
1.3.4 Puppet（ruby语言开发）（了解）
每隔30分钟，通过RPC消息队列将执行的结果返回给用户
二 三种方案客户端编写
2.1 目录结构划分
autoclient # 项目名
-bin # 启动文件路径
-start.py # 启动文件
-config # 配置文件路径
-cert # 私钥
-custom_settings.py # 用户自定义配置
-files # 测试数据文件
-board.out
-cpuinfo.out
-disk.out
-memory.out
-nic.out
-lib # 库文件夹
-conf # 配置信息文件夹
-config.py # 配置类
-global_settings.py # 全局常量配置
-convert.py # 公共方法
-src # 源文件
-plugins # 插件
-__init__.py # 初始化文件
-basic.py
-board.py
-cpu.py
-disk.py
-memory.py
-nic.py
script.py # 脚本文件
client.py # 客户端类
tests # 测试文件夹
# 总结：bin，config，files，lib，src几个文件夹
2.2 仿django配置文件
custom_settings.py
# 用户配置
PORT = 22
USER = 'lqz'
global_settings.py
#### 全局配置
PORT = 22
USER = 'root'
config.py
from config import custom_settings
from . import global_settings
class Settings():
def __init__(self):
#### 全局配置
for key in dir(global_settings):
if key.isupper():
#### 获取key所对应的值
v = getattr(global_settings, key)
#### 设置key以及值到当前的setting对象
setattr(self, key, v)
#### 自定制配置
for key in dir(custom_settings):
if key.isupper():
#### 获取key所对应的值
v = getattr(custom_settings, key)
#### 设置key以及值到当前的setting对象
setattr(self, key, v)
settings = Settings()

# API清洗的时候:
应该在新的POST数据中选取一个 唯一 的字段， 然后到数据库中作为where条件， 获取到对应的数据
问题是 应该选取谁？
选取的是 sn 序列号（mac地址） 作为唯一的字段
用sn遇到的问题：
虚拟机和实体机共用一个sn， 导致数据不准确
# 解决的方案：
a. 如果公司不需要采集虚拟机的信息， 使用sn没有问题
b. 采用 hostname 作为唯一标识
- 是允许开发可以临时修改主机名的
-实现方案：
-1. 给这些服务器分配唯一的主机名
-2 将分配好的主机名录入到后台管理的DBserver表中
-3. 将采集的client客户端代码， 运行一次
-4 然后将得到的主机名地址保存到一个文件中
第一天：
1. 给这些服务器分配唯一的主机名
2. 将分配好的主机名录入到后台管理的DBserver表中
3. 将采集的client客户端代码， 运行一次，
然后将得到的主机名地址保存到一个文件中
第二天：
