概述
数仓采集之环境搭建sqoop,hive
安装mysql
参数之前的hive安装mysql的步骤：https://blog.csdn.net/weixin_44178366/article/details/120559203?spm=1001.2014.3001.5501
安装好mysql之后将mock的数据导入新建的gmall数据库
生成数据
# 修改application.properties,先修改为重置为1
[atguigu@hadoop102 db_log]$ pwd
/opt/module/db_log
[atguigu@hadoop102 db_log]$ ll
total 14780
-rw-r--r-- 1 atguigu atguigu 1601 Oct 19 23:08 application.properties
-rw-r--r-- 1 atguigu atguigu 15127607 Oct 19 23:08 gmall2020-mock-db-2021-01-22.jar
[atguigu@hadoop102 db_log]$
编写生成数据的脚本 db.sh
#!/bin/bash
for i in hadoop102
do
ssh $i 'cd /opt/module/db_log;java -jar gmall2020-mock-db-2021-01-22.jar 1>/dev/null 2>&1 &'
done
业务数据建模
可借助EZDML这款数据库设计工具，来辅助我们梳理复杂的业务表关系。

sqoop安装
#1.下载并解压
1）下载地址：http://mirrors.hust.edu.cn/apache/sqoop/1.4.6/
2）上传安装包sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz到hadoop102的/opt/software路径中
3）解压sqoop安装包到指定目录，如：
[atguigu@hadoop102 software]$ tar -zxf sqoop-1.4.6.bin__hadoop-2.0.4-alpha.tar.gz -C /opt/module/
4）解压sqoop安装包到指定目录，如：
[atguigu@hadoop102 module]$ mv sqoop-1.4.6.bin__hadoop-2.0.4-alpha/ sqoop-1.4.6
#2.修改配置文件
1) 进入到/opt/module/sqoop-1.4.6/conf目录，重命名配置文件
[atguigu@hadoop102 conf]$ mv sqoop-env-template.sh sqoop-env.sh
2) 修改配置文件
[atguigu@hadoop102 conf]$ vim sqoop-env.sh
增加如下内容
export HADOOP_COMMON_HOME=/opt/module/hadoop-3.1.3
export HADOOP_MAPRED_HOME=/opt/module/hadoop-3.1.3
export HIVE_HOME=/opt/module/hive
export ZOOKEEPER_HOME=/opt/module/zookeeper-3.5.7
export ZOOCFGDIR=/opt/module/zookeeper-3.5.7/conf
# 添加sqoop的环境变量
#sqoop
export SQOOP_HOME=/opt/module/sqoop-1.4.6
export PATH=$PATH:$SQOOP_HOME/bin
#3.拷贝JDBC驱动
1）将mysql-connector-java-5.1.48.jar 上传到/opt/software路径
2）进入到/opt/software/路径，拷贝jdbc驱动到sqoop的lib目录下。
[atguigu@hadoop102 software]$ cp mysql-connector-java-5.1.48.jar /opt/module/sqoop-1.4.6/lib/
2.3.4 验证Sqoop
我们可以通过某一个command来验证sqoop配置是否正确：
[atguigu@hadoop102 sqoop]$ bin/sqoop help
出现一些Warning警告（警告信息已省略），并伴随着帮助命令的输出：
Available commands:
codegen Generate code to interact with database records
create-hive-table Import a table definition into Hive
eval Evaluate a SQL statement and display the results
export Export an HDFS directory to a database table
help List available commands
import Import a table from a database to HDFS
import-all-tables Import tables from a database to HDFS
import-mainframe Import datasets from a mainframe server to HDFS
job Work with saved jobs
list-databases List available databases on a server
list-tables List available tables in a database
merge Merge results of incremental imports
metastore Run a standalone Sqoop metastore
version Display version information
2.3.5 测试Sqoop是否能够成功连接数据库
[atguigu@hadoop102 sqoop]$ bin/sqoop list-databases --connect jdbc:mysql://hadoop102:3306/ --username root --password 123456
出现如下输出：
information_schema
metastore
mysql
oozie
performance_schema
测试mysq导出数据到hdfs
需求一：将user_info表中的id，login_name,nick_name字段的值导入到hdfs中，
只要求导入id范围在100-200的
# select id,login_name,nick_name from user_info where id >=100 and id <=200
sqoop import
--connect jdbc:mysql://hadoop102:3306/gmall
--username root
--password 123456
--table user_info
--columns id,login_name,nick_name
--where "id >=100 and id <=200"
--target-dir /testsqoop
--delete-target-dir
--num-mappers 2
--fields-terminated-by "t"
# 使用-- query
sqoop import
--connect jdbc:mysql://hadoop102:3306/gmall
--username root
--password 123456
--query "select id,login_name,nick_name from user_info where id >=100 and id <=200 and $CONDITIONS "
--target-dir /testsqoop
--delete-target-dir
--num-mappers 2
--split-by id
--fields-terminated-by "t"
sqoop同步策略
数据同步策略的类型包括：全量同步、增量同步、新增及变化同步、特殊情况
- Ø 全量表：存储完整的数据。
- Ø 增量表：存储新增加的数据。
- Ø新增及变化表：存储新增加的数据和变化的数据。
- Ø 特殊表：只需要存储一次。
全量同步策略
每日全量，就是每天存储一份完整的数据，作为一个分区
增量同步策略
每日增量，就是每天存储一份增量数据，作为一个分区。适用于数据量大的表
新增及变化策略
每日新增及变化，就是存储创建时间和操作时间，都是今天的数据。适用场景：表的数据量大，既会有新增，又会有变化
特殊策略
某些特殊的表，可不必遵循上述同步策略。
例如没变化的客观世界的数据（比如性别，地区，民族，政治成分，鞋子尺码）可以只存一份。
业务数据导入hdfs
分析表同步策略
在生产环境，个别小公司，为了简单处理，所有表全量导入。
中大型公司，由于数据量比较大，还是严格按照同步策略导入数据。
同步脚本分析
首日同步脚本 mysql_to_hdfs_init.sh
#! /bin/bash
APP=gmall
sqoop=/opt/module/sqoop-1.4.6/bin/sqoop
# 调用该脚本，会传入一个表名，日期
# 如果是输入的日期按照取输入日期；如果没输入日期取当前时间的前一天,-n判断是否存在
# 注意：如果配置了lzo压缩的话一定要在hadoop配置lzo的压缩格式（详细见hadoop的安装配置）
if [ -n "$2" ] ;then
do_date=$2
else
echo "请传入日期参数"
exit
fi
# 导数据同步函数：传入表名和sql

安装hive
1.解压安装
1）把apache-hive-3.1.2-bin.tar.gz上传到linux的/opt/software目录下
2）解压apache-hive-3.1.2-bin.tar.gz到/opt/module/目录下面
[atguigu@hadoop102 software]$ tar -zxvf /opt/software/apache-hive-3.1.2-bin.tar.gz -C /opt/module/
3）修改apache-hive-3.1.2-bin.tar.gz的名称为hive
[atguigu@hadoop102 software]$ mv /opt/module/apache-hive-3.1.2-bin/ /opt/module/hive
4）修改/etc/profile.d/my_env.sh，添加环境变量
[atguigu@hadoop102 software]$ sudo vim /etc/profile.d/my_env.sh
添加内容
#HIVE_HOME
export HIVE_HOME=/opt/module/hive
export PATH=$PATH:$HIVE_HOME/bin
重启Xshell对话框或者source一下 /etc/profile.d/my_env.sh文件，使环境变量生效
[atguigu@hadoop102 software]$ source /etc/profile.d/my_env.sh
5）解决日志Jar包冲突，进入/opt/module/hive/lib目录
[atguigu@hadoop102 lib]$ mv log4j-slf4j-impl-2.10.0.jar log4j-slf4j-impl-2.10.0.jar.bak
2.hive元数据配置到mysql
#1 拷贝驱动
将MySQL的JDBC驱动拷贝到Hive的lib目录下
[atguigu@hadoop102 lib]$ cp /opt/software/mysql-connector-java-5.1.48.jar /opt/module/hive/lib/
#2 配置Metastore到MySQL
在$HIVE_HOME/conf目录下新建hive-site.xml文件
[atguigu@hadoop102 conf]$ vim hive-site.xml
# 添加如下内容
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://hadoop102:3306/metastore?useSSL=false</value>
</property>
<property>
<name>javax.jdo.option.ConnectionDriverName</name>
<value>com.mysql.jdbc.Driver</value>
</property>
<property>
<name>javax.jdo.option.ConnectionUserName</name>
<value>root</value>
</property>
<property>
<name>javax.jdo.option.ConnectionPassword</name>
<value>123456</value>
</property>
<property>
<name>hive.metastore.warehouse.dir</name>
<value>/user/hive/warehouse</value>
</property>
<property>
<name>hive.metastore.schema.verification</name>
<value>false</value>
</property>
<property>
<name>hive.server2.thrift.port</name>
<value>10000</value>
</property>
<property>
<name>hive.server2.thrift.bind.host</name>
<value>hadoop102</value>
</property>
<property>
<name>hive.metastore.event.db.notification.api.auth</name>
<value>false</value>
</property>
<property>
<name>hive.cli.print.header</name>
<value>true</value>
</property>
<property>
<name>hive.cli.print.current.db</name>
<value>true</value>
</property>
</configuration>
3.初始化元数据
#初始化元数据库
1）登陆MySQL
[atguigu@hadoop102 conf]$ mysql -uroot -p000000
2）新建Hive元数据库
mysql> create database metastore;
mysql> quit;
3）初始化Hive元数据库
[atguigu@hadoop102 conf]$ schematool -initSchema -dbType mysql -verbose
4）启动Hive客户端
[atguigu@hadoop102 hive]$ hive
5）查看一下数据库
hive (default)> show databases;
OK
database_name
default
自此，整个数据采集通道全部打通，测试ok
日志信息：从生成然后自动上传到HDFS
业务数据：从生成然后手动导入HDFS,可结合定时任务自动去导
