1. CMD是什么以及发挥什么样的作用

1.1：CMDB架构

文档使用CMDB部署redis集群来演示

1.2：CMDB核心功能

1、使用CMDB部署的服务，会服务器记录所有设备信息 ，包括机房，公网IP/私网，集群信息，负责人，连接交换机端口

带宽，硬盘，CPU内存等信息

2、在CMDB可以对服务管理维护，任意增删改查

3、CMDB可以配置图形界面，也可以使用命令终端操作

1.3：CMDB完成的工作

1. 选择安装哪些集群包
2. 推送新的服务器的DNS解析记录（内网，外网解析，以及DNS domain的C/S同步工作）
3. 新添加的服务器自动加入监控系统，包括在监控平台添加新节点
4. 生成防火墙规则，以及配置网络设备相关

二、CMDB的整体业务架构

客户端服务端架构，使用tcp通讯（不使用ssh）

2.1: 架构简介

1. c/s模型
2. 服务端负责调用数据库，并且实时和客户端保持通信
3. 客户端：配置agent端（脚本）在每一台客户端机器上，agent作为沟通的中间件，让所有客户端节点与服务端保持实时联系
4. 网络通讯：使用的tcp协议，ssh协议数量大了效率低(还需要配置公钥私钥
5. 数据库需要设计表结构，存储客户端以及部署的服务信息

2.2：部署redis准备

目录分配：

软件安装：/usr/local/redis/ #启动redis进程

配置文件：/usr/local/etc/redis #redis配置文件

redis存储目录：/data/.xxxx #存储一般单独分目录，给定足够空间，用隐藏目录是为了安全

日志目录： /data/log

redis是单线程运行，需要拆分成多个实例来启动（提升效率）

三、环境配置

基本环境准备，至少3台服务器

1. cmdb服务端
2. redis+cmdb客户端
3. 任意监控系统+cmdb

3.1: 做好cmdb服务端的解析工作

修改/etc/hosts,或者配置named解析。解析cmdb服务端

3.2：配置好python3的环境

yum install python3

3.3：第一台机器服务端配置好mysql server的环境

下载并安装mysql官方的yum repository

在server01上安装

[root@localhost ~]# wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm

[root@localhost ~]# yum -y install mysql57-community-release-el7-10.noarch.rpm

安装mysql

server01

[root@localhost ~]# yum -y install mysql-community-server

mysql数据库启动

server01

[root@localhost ~]# systemctl start mysqld.service

[root@localhost ~]# systemctl status mysqld.service

修改mysql密码

server01

[root@localhost ~]# grep "password" /var/log/mysqld.log

[root@localhost ~]# mysql -uroot -p

输⼊入初始密码，此时不不能做任何事情，因为MySQL默认必须,修改密码之后才能操作数据库：

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '123456';

下载安装pymysql库

server01

接下来 我们在第⼀一台机器器上 安装⼀一下 python3 需要调⽤用。pymysql 为了了后⾯面 可以操作DB

wget https://files.pythonhosted.org/packages/44/39/6bcb83cae0095a31b6be4511707fdf2009d3e29903a55a0494d3a9a2fac0/PyMySQL-0.8.1.tar.gz

ls

tar -xvzf PyMySQL-0.8.1.tar.gz

cd PyMySQL-0.8.1/

python setup.py install

python3

import pymysql没问题，说明安装成功

在server01上安装FTP服务

yum install vsftpd

service vsftpd start

默认的ftp路径：/var/ftp/pub/ #将软件包拷贝到该目录

为什么需要ftp服务？

1、当需要在客户端安装服务时，在服务端下载安装包安装

3.4: 在client01和02安装python3

客户端只需要安装python3，不需要安装pymysql，因为与数据库通信，是客户端通过服务端调用数据库

3.5：在client02安装nagios

nagios的配置文件后面将由cmdb来生成

host.cfgèdefine server

四、CMDB的mysql数据库结构

第一张表

第二张表

第三张表

存储定义类型，如定义redis nginx

结果如下：

建表语句

python使用 pymysql模块创建sql表格代码：

#存储服务器信息

sql = """CREATE TABLE IF NOT EXISTS SERVERS (

SERVER_ID SMALLINT UNSIGNED NOT NULL auto_increment,        #服务id

SERVERNAME CHAR(30) NOT NULL,                 #可以被解析成ip的机器名

INTERNAL_IP CHAR(20) NOT NULL,            #ip地址

ONLINE BOOLEAN,                服务器是否在线

PRIMARY KEY(SERVER_ID))"""             主键是server—id

cursor.execute(sql)

#存储进程信息表

sql = """CREATE TABLE IF NOT EXISTS PROCESS (

PROCESS_ID SMALLINT UNSIGNED NOT NULL auto_increment,     #安装软件的进程id

PROCESS_NAME CHAR(20) NOT NULL, #进程名

SERVER_ID SMALLINT UNSIGNED NOT NULL,                第一张服务器表对应的server-id，进程位于那台服务器上

SERVICE_ID SMALLINT UNSIGNED NOT NULL,             第三张表service表对应的service-id，进程对应的类型

MASTER BOOLEAN,            #是否为主，比如redis的主从，其他服务默认应当是主

SLAVE BOOLEAN,            #是否为从

PORT SMALLINT UNSIGNED,                #端口号

ONLINE BOOLEAN, #是否在线

PRIMARY KEY(PROCESS_ID))"""

cursor.execute(sql)

#存储服务id表

sql = """CREATE TABLE IF NOT EXISTS SERVICE (

SERVICE_ID SMALLINT UNSIGNED NOT NULL auto_increment,

SERVICE_NAME CHAR(20) NOT NULL,

PRIMARY KEY(SERVICE_ID))"""

cursor.execute(sql)

五、CMDB的菜单代码模块

准备

菜单模块2

异常退出，关闭进程的方法

六、CMDB的C/S模块和网络通讯的利用

七、CMDB的子进程代码模块

开启一个子进程

八、CMDB的推送部署模块

九、CMDB整体联调

代码

cmdb.py

环境代码
