Logistics_Day03:业务服务器和大数据服务器

01-[复习]-上次课程内容回顾

主要讲解Docker 基本使用:Docker是什么、Docker 基本命令(镜像image命令和容器container命令)。

Docker容器引擎:虚拟化技术,将应用运行在容器Container中,方便进行部署、测试、迁移等开发操作。

  • 1)、Docker 容器引擎,典型C/S架构,客户端Client和服务端Server
  • 2)、Docker核心组件
  • Repository注册中心中央仓库:hub.docker.com
  • 镜像image,类似模板Template,可以从中央仓库拉取pull,也可以从Dockerfile构建
  • 容器container,类似创建具体实例
  • 3)、Docker命令
  • 镜像命令:search,pull,list,rmi
  • 容器命令:查看ps,创建run,启动与停止,删除容器

02-[了解]-第3天:课程内容提纲

主要讲解:如何将业务系统(仅仅以物流系统Logistics和客户关系管理系统CRM为例)实时增量采集数据到分布式消息队列Kafka(1个业务系统存储1个Topic:一对一)。

  • 1)、Oracle数据库(物流系统Logistics):使用OGG框架实时采集
1)、业务服务器数据库
  物流系统Logistics:Oracle数据库,运行在Docker容器
  客户关系管理系统CRM:MySQL 数据库,运行在Docker容器
2)、OGG 实时采集Oracle数据库表数据
  原理架构
  【如何配置】:OGG配置,一般都是Oracle数据库DBA,直接部署到Docker容器
  使用、测试

03-[理解]-业务服务器环境概述

解压提供项目虚拟机【node1.itcast.cn】和【node2.itcast.cn】,导入到VMWare虚拟机软件中,调整虚拟机资源配置,截图如下:

提供2个虚拟机,如果后续使用中,发现服务不可用时,直接删除虚拟机,重新解压,再次导入使用即可。

node2.itcast.cn 虚拟机来说,导入VMware以后,首次启动时,默认情况将安装所有大数据框架服务启动,需要稍等3-5分钟(至少),所有服务启动完成,登录CM界面:http://node2.itcast.cn:7180,关闭所有服务。

CM界面登录用户名和密码:admin/admin

物流项目中,为了简化,以物流系统和CRM系统为例,将业务数据存储到数据库中:

所有服务器使用数据库,都是部署在【node1.itcast.cn】机器上,查看镜像和容器

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-vdUCadCo-1621469545862)(/img/1615773180502.png)]

如下图所示,在node1.itcast.cn镜像如下:

查看node1.itcast.cn创建容器,依据存在镜像image创建,在容器中运行服务:MySQL数据库、Oracle数据库。

只要启动相应应用容器即可,比如启动MySQL数据库运行的容器,就可以使用MySQL数据库。

04-[掌握]-业务服务器之Oracle 数据库

首先物流系统Logistics使用Oracle数据库,采用Docker容器部署,启动容器Contanier,再启动Oracles数据库,进行访问,查看数据库database中表:物流系统相关业务表。

  • 1)、针对myoracle容器来说,启动容器以后,不会启动Oracle数据库相关服务,需要手动启动
  • 2)、Oracle数据库相关服务:数据库服务Server和监听服务Listener。

05-[掌握]-业务服务器之MySQL 数据库

客户关系管理系统CRM使用MySQL数据库存储业务数据,同样也是使用Docker 容器部署,启动容器(容器启动以后,就会启动MySQL数据库)。

启动容器,并且使用客户端DBeave连接MySQL数据库,方便操作数据库中表的数据

# 使用VMWare 启动node1.itcast.cn虚拟机,使用root用户(密码123456)登录
[root@node1 ~]# docker ps -a

06-[掌握]-OGG 数据同步之功能概述

针对整个物流项目来说,数据采集属于实时增量采集数据,只要业务数据一旦产生,就立即将业务数据获取,进行ETL转换,存储到存储引擎中(比如Kudu数据库和Es索引等)。

  • 1)、业务数据量比较多,快速存储
  • 2)、实时性业务分析统计,快速分析

使用OGG中间件(框架)实时采集Oracle数据库表的数据,同步到Kafka分布式消息队列中。

OGG 是一种基于日志的结构化数据复制软件,它通过解析源数据库在线日志:online log或归档日志:archive log获得数据的增删改变化(数据量只有日志的四分之一左右);

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-U2k9pp4B-1621469545868)(/img/1612320791630.png)]

OGG 能够实现大量交易数据的实时捕捉,变换和投递,实现源数据库与目标数据库的数据同步,保持最少10ms的数据延迟。

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-tIH4Mh89-1621469545868)(/img/1615776620433.png)]

应用场景:主要三个方面

  • 高可用(HA:High Availability)容灾
  • 数据库迁移、升级(支持跨版本、异构数据库、零宕机时间、亚秒级恢复)
  • 实时数据集成(支持异构数据库、多源数据库)

07-[掌握]-OGG 数据同步之基本原理及架构

Oracle GoldenGate 实现原理是通过抽取源端的redo log 或者 archive log ,然后通过TCP/IP投递到目标端,最后解析还原应用到目标端,使目标端实现 同源端数据同步。

详细OGG如何数据同步,基本原理和架构:

  • 1)、源端(SRC):获取Oracle数据表数据,从日志文件获取
  • 管理者:MGR(Manger)
  • 第一、进程:Extract提取进程,获取日志数据文件
  • 第二、本地缓存:Local TrailFile,将日志文件数据存储到本地TrailFile文件中,缓存
  • 第三、进程:(可选)Pump进程,将本地Local TrailFile发送给目标端
  • 2)、目标端(DST):发送数据到目标,如Topic
  • 管理者:MGR(Manger)
  • 第一、进程:Collect进程,接收源端pump进程发送的数据,新版添加进程
  • 第二、远程缓存:RemoteTrailFile,目标端接收到数据文件以后,进行缓存
  • 第三、进程:Replicat进程,复制进程,解析RemoteTrailFile文件,转换JSON格式,发送到Kafka

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-M4wB1aH3-1621469545869)(/img/1612321610205.png)]

OGG采集数据时,完整结构如上如所示:分为源端SRC和目标端DST,都有自己管理进程MGR。

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-qurbjIwG-1621469545870)(/img/1615777550837.png)]

Extract 进程用来捕获数据源,有三种类型:

  • 1)、initial load:加载整张表的数据,属于批量加载
  • 2)、恢复日志/事务日志:恢复数据库表的数据
  • 3)、捕获模型,实时监控日志文件,已有数据,立即捕获

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-LP2bY0Co-1621469545870)(/img/1615777650890.png)]

Data pump 是Extract的辅助可选组件,如果不配置Data pump,Extract将捕获的数据直接发给目标机器上的Collector进程。

08-[理解]-OGG 数据同步之拓扑结构及支持环境

OGG架构和原理,发现架构划分比较细(分工比较细),OGG在实际项目中,使用时,常见拓扑结构和支持环境,以后如果考虑使用OGG实时同步数据时参考。

Oracle数据库配置集群Cluster,称为Oracle RAC(Real Application Cluster

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-f1CDtZFO-1621469545870)(/img/1615778086744.png)]

由此可见,GoldenGate TDM的复制模式非常灵活,用户可以根据自己的需求选择特定的复制方式,并根据系统扩展对复制进行扩展。

源和目标的操作系统和数据库可以进行任意的组合。

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-to6k01Ee-1621469545871)(/img/1615778445595.png)]

目前来说,如果企业项目使用OGG进行数据同步时,通常还是SRC为:Oracle数据库,DST:Oracle数据库或Kafka消息队列。

09-[掌握]-OGG 数据同步之测试环境准备

如何配置OGG实现实时数据同步到Kafka,无需掌握步骤,比较繁琐,让DBA完成。

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-pimIV7dm-1621469545871)(/img/1615779520603.png)]

提供虚拟机【node1.itcast.cn】中Docker 容器【myoracle】已经安装完OGG(源端和目标端),只需要启动OGG的源端SRC服务和目标端DST服务即可。

  • 1)、源端SRC
  • Manager管理(mgr)、Extract进程、LocalTrail、Pump进程
  • 2)、目标端DST
  • Manager管理(mgr)、Remote Trail 、复制进程Replicat

[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-wv9v9JjV-1621469545872)(/img/1612324623208.png)]

由于使用OGG实时采集Oracle数据库表数据(日志文件),将数据同步到Kafka消息对象,所以首先启动Kafka服务(先启动Zookeeper服务),打开提供【node2.itcast.cn】,使用CM界面启动ZK和Kafka服务。

启动OGG配置服务,分为源端和目标端,参考提供【启动命令:Oracle数据库和OGG服务.txt】,具体命令;

使用KafkaTool工具连接Kafka集群,查看Topic信息和数据

10-[掌握]-OGG 数据同步之物流数据同步Kafka

采用OGG中间件将Oracle数据库表的数据实时同步到Kafka消息队列中:

  • 1)、源端 :Oracle数据库【itcast】
  • 2)、采集工具:OGG,分为SRC和DST
  • 3)、目标端:Kafka 消息队列【logistics】

测试:向Oracle数据库某张表中插入insert、更新update及删除delete操作,查看Kafka Topic中数据

目前OGG11版本,延迟性相对较大,在2s左右,需要进行合理化调参配置,到OGG12版本,很快。

  • 1)、插入数据测试
-- 插入数据INSERT
INSERT INTO ITCAST."tbl_company"("id", "company_name", "city_id", "company_number", "company_addr", "company_addr_gis", "company_tel", "is_sub_company", "state", "cdt", "udt", "remark")VALUES(11, '广州传智速递邮箱公司', 440100, NULL, '广州校区', '117.28177895734918_31.842711680531399', NULL, 1, 1, TO_DATE('2020-06-13 15:24:51','yyyy-mm-dd hh24:mi:ss'), TO_DATE('2020-06-13 15:24:51','yyyy-mm-dd hh24:mi:ss'), NULL);

同步至Kafka Topic中JSON数据

{
  "table": "ITCAST.tbl_company",
  "op_type": "I",
  "op_ts": "2021-03-15 03:57:07.000306",
  "current_ts": "2021-03-15T03:57:20.578000",
  "pos": "00000000150000001245",
  "after": {
    "id": 11,
    "company_name": "广州传智速递邮箱公司",
    "city_id": 440100,
    "company_number": null,
    "company_addr": "广州校区",
    "company_addr_gis": "117.28177895734918_31.842711680531399",
    "company_tel": null,
    "is_sub_company": 1,
    "state": 1,
    "cdt": "2020-06-13 15:24:51",
    "udt": "2020-06-13 15:24:51",
    "remark": null
  }
}
  • 2)、更新数据测试
-- 更新数据UPDATE
UPDATE ITCAST."tbl_company" SET "company_name"='广州传智速递有限公司-1' WHERE "id"=11;

同步至Kafka Topic中JSON数据

{
  "table": "ITCAST.tbl_company",
  "op_type": "U",
  "op_ts": "2021-03-15 03:59:28.000248",
  "current_ts": "2021-03-15T03:59:40.378000",
  "pos": "00000000150000001980",
  "before": {
    "id": 11,
    "company_name": "广州传智速递邮箱公司",
    "city_id": 440100,
    "company_number": null,
    "company_addr": "广州校区",
    "company_addr_gis": "117.28177895734918_31.842711680531399",
    "company_tel": null,
    "is_sub_company": 1,
    "state": 1,
    "cdt": "2020-06-13 15:24:51",
    "udt": "2020-06-13 15:24:51",
    "remark": null
  },
  "after": {
    "id": 11,
    "company_name": "广州传智速递有限公司-1",
    "city_id": 440100,
    "company_number": null,
    "company_addr": "广州校区",
    "company_addr_gis": "117.28177895734918_31.842711680531399",
    "company_tel": null,
    "is_sub_company": 1,
    "state": 1,
    "cdt": "2020-06-13 15:24:51",
    "udt": "2020-06-13 15:24:51",
    "remark": null
  }
}
  • 3)、删除数据测试
-- 删除数据DELETE
DELETE ITCAST."tbl_company" WHERE "id"=11;

同步至Kafka Topic中JSON数据

{
  "table": "ITCAST.tbl_company",
  "op_type": "D",
  "op_ts": "2021-03-15 04:01:16.000109",
  "current_ts": "2021-03-15T04:01:30.756000",
  "pos": "00000000150000002328",
  "before": {
    "id": 11,
    "company_name": "广州传智速递有限公司-1",
    "city_id": 440100,
    "company_number": null,
    "company_addr": "广州校区",
    "company_addr_gis": "117.28177895734918_31.842711680531399",
    "company_tel": null,
    "is_sub_company": 1,
    "state": 1,
    "cdt": "2020-06-13 15:24:51",
    "udt": "2020-06-13 15:24:51",
    "remark": null
  }
}
