cd /opt/server/hadoop-3.1.0/sbin/

./start-dfs.sh
./start-yarn.sh

# 或者
./start-all.sh

一、爬取数据

1.1、歌单信息

sql 复制代码 
CREATE TABLE playlist (
    PlaylistID INT AUTO_INCREMENT PRIMARY KEY,
    Type VARCHAR(255),
    Title VARCHAR(255),
    PlayCount VARCHAR(255),
    Contributor VARCHAR(255)
);

            playlist_data = (type, title, playCount, contributor)
            cursor.execute(insert_query, playlist_data)
            db_connection.commit()

            time.sleep(0.1)
cursor.close()
db_connection.close()

        db_connection.commit()

        time.sleep(1)
cursor.close()
db_connection.close()

二、搭建环境

1.1、搭建JAVA

bash 复制代码 
mkdir /opt/tools
mkdir /opt/server

tar -zvxf jdk-8u131-linux-x64.tar.gz -C /opt/server
bash 复制代码 
vim /etc/profile

# 文件末尾增加
export JAVA_HOME=/opt/server/jdk1.8.0_131
export PATH=${JAVA_HOME}/bin:$PATH

source /etc/profile

java -version

1、配置免密登录

bash 复制代码 
vim /etc/hosts
# 文件末尾增加
192.168.88.110  [主机名]
bash 复制代码 
ssh-keygen -t rsa

cd ~/.ssh
cat id_rsa.pub >> authorized_keys
chmod 600 authorized_keys

1.2、配置hadoop

bash 复制代码 
tar -zvxf hadoop-3.1.0.tar.gz -C /opt/server/
bash 复制代码 
# 进入/opt/server/hadoop-3.1.0/etc/hadoop
vim hadoop-env.sh
# 文件添加
export JAVA_HOME=/opt/server/jdk1.8.0_131

vim core-site.xml

xml 复制代码 
<configuration>
    <property>
        <!--指定 namenode 的 hdfs 协议文件系统的通信地址-->
        <name>fs.defaultFS</name>
        <value>hdfs://[主机名]:8020</value>
    </property>
    <property>
        <!--指定 hadoop 数据文件存储目录-->
        <name>hadoop.tmp.dir</name>
        <value>/home/hadoop/data</value>
    </property>
</configuration>

hdfs-site.xml

xml 复制代码 
<configuration>
    <property>
        <!--由于我们这里搭建是单机版本，所以指定 dfs 的副本系数为 1-->
        <name>dfs.replication</name>
        <value>1</value>
    </property>
</configuration>
bash 复制代码 
vim workers
# 配置所有从属节点的主机名或 IP 地址，由于是单机版本，所以指定本机即可：
server

1、关闭防火墙

bash 复制代码 
# 查看防火墙状态
sudo firewall-cmd --state
# 关闭防火墙:
sudo systemctl stop firewalld
# 禁止开机启动
sudo systemctl disable firewalld

2、初始化

bash 复制代码 
cd /opt/server/hadoop-3.1.0/bin
./hdfs namenode -format

3、配置启动用户

bash 复制代码 
cd /opt/server/hadoop-3.1.0/sbin/
# 编辑start-dfs.sh、stop-dfs.sh,在顶部加入以下内容
# 编辑start-all.sh、stop-all.sh,在顶部加入以下内容
HDFS_DATANODE_USER=root
HDFS_DATANODE_SECURE_USER=hdfs
HDFS_NAMENODE_USER=root
HDFS_SECONDARYNAMENODE_USER=root

4、启动

bash 复制代码 
cd /opt/server/hadoop-3.1.0/sbin/
./start-dfs.sh

jps

5、访问

bash 复制代码 
192.168.88.110:9870

6、配置环境变量方便启动

bash 复制代码 
vim /etc/profile
export HADOOP_HOME=/opt/server/hadoop-3.1.0
export PATH=$PATH:${HADOOP_HOME}/bin:${HADOOP_HOME}/sbin
source /etc/profile

1.3、配置Hadoop环境：YARN

bash 复制代码 
# 进入/opt/server/hadoop-3.1.0/etc/hadoop
vim mapred-site.xml
xml 复制代码 
<configuration>
    <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
    </property>
    <property>
        <name>yarn.app.mapreduce.am.env</name>
        <value>HADOOP_MAPRED_HOME=${HADOOP_HOME}</value>
    </property>
    <property>
        <name>mapreduce.map.env</name>
        <value>HADOOP_MAPRED_HOME=${HADOOP_HOME}</value>
    </property>
    <property>
        <name>mapreduce.reduce.env</name>
        <value>HADOOP_MAPRED_HOME=${HADOOP_HOME}</value>
    </property>
</configuration>
bash 复制代码 
vim yarn-site.xml
xml 复制代码 
<configuration>
    <property>
        <!--配置 NodeManager 上运行的附属服务。需要配置成 mapreduce_shuffle 后才可
			以在Yarn 上运行 MapRedvimuce 程序。-->
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>
</configuration>
bash 复制代码 
cd /opt/server/hadoop-3.1.0/sbin/
# start-yarn.sh stop-yarn.sh在两个文件顶部添加以下内容
YARN_RESOURCEMANAGER_USER=root
HADOOP_SECURE_DN_USER=yarn
YARN_NODEMANAGER_USER=root
bash 复制代码 
./start-yarn.sh


1.4、MYSQL

bash 复制代码 
# 用于存放安装包
mkdir /opt/tools
# 用于存放解压后的文件
mkdir /opt/server

卸载Centos7自带mariadb

bash 复制代码 
# 查找
rpm -qa|grep mariadb
# mariadb-libs-5.5.52-1.el7.x86_64
# 卸载
rpm -e mariadb-libs-5.5.52-1.el7.x86_64 --nodeps
bash 复制代码 
# 创建mysql安装包存放点
mkdir /opt/server/mysql
# 解压
tar xvf mysql-5.7.34-1.el7.x86_64.rpm-bundle.tar -C /opt/server/mysql/
bash 复制代码 
# 安装依赖
yum -y install libaio
yum -y install libncurses*
yum -y install perl perl-devel
# 切换到安装目录
cd /opt/server/mysql/
# 安装
rpm -ivh mysql-community-common-5.7.34-1.el7.x86_64.rpm 
rpm -ivh mysql-community-libs-5.7.34-1.el7.x86_64.rpm 
rpm -ivh mysql-community-client-5.7.34-1.el7.x86_64.rpm 
rpm -ivh mysql-community-server-5.7.34-1.el7.x86_64.rpm
bash 复制代码 
#启动mysql
systemctl start mysqld.service
#查看生成的临时root密码
cat /var/log/mysqld.log | grep password
bash 复制代码 
# 登录mysql
mysql -u root -p
Enter password:     #输入在日志中生成的临时密码
# 更新root密码 设置为root
set global validate_password_policy=0;
set global validate_password_length=1;
set password=password('root');
bash 复制代码 
grant all privileges on *.* to 'root' @'%' identified by 'root';
# 刷新
flush privileges;
bash 复制代码 
#mysql的启动和关闭 状态查看
systemctl stop mysqld
systemctl status mysqld
systemctl start mysqld
#建议设置为开机自启动服务
systemctl enable mysqld
#查看是否已经设置自启动成功
systemctl list-unit-files | grep mysqld

1.5、HIVE(数据仓库)

bash 复制代码 
# 切换到安装包目录
cd /opt/tools
# 解压到/root/server目录
tar -zxvf apache-hive-3.1.2-bin.tar.gz -C /opt/server/
bash 复制代码 
# 上传mysql-connector-java-5.1.38.jar到下面目录
cd /opt/server/apache-hive-3.1.2-bin/lib

配置文件

bash 复制代码 
cd /opt/server/apache-hive-3.1.2-bin/conf
cp hive-env.sh.template hive-env.sh
vim hive-env.sh
# 加入以下内容
HADOOP_HOME=/opt/server/hadoop-3.1.0
bash 复制代码 
cd /opt/server/apache-hive-3.1.2-bin/conf
vim hive-site.xml
xml 复制代码 
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <!-- 存储元数据mysql相关配置 /etc/hosts -->
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value> jdbc:mysql://[主机名]:3306/hive?
createDatabaseIfNotExist=true&amp;useSSL=false&amp;useUnicode=true&amp;chara
cterEncoding=UTF-8</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>root</value>
    </property>
</configuration>

初始化表

bash 复制代码 
cd /opt/server/apache-hive-3.1.2-bin/bin
./schematool -dbType mysql -initSchema


1.6、Sqoop（关系数据库数据迁移）

1、拉取sqoop

bash 复制代码 
# /opt/tools
wget https://archive.apache.org/dist/sqoop/1.4.7/sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz

tar -zxvf sqoop-1.4.7.bin__hadoop-2.6.0.tar.gz -C /opt/server/

2、配置

bash 复制代码 
cd /opt/server/sqoop-1.4.7.bin__hadoop-2.6.0/conf
cp sqoop-env-template.sh sqoop-env.sh

vim sqoop-env.sh
# 加入以下内容
export HADOOP_COMMON_HOME=/opt/server/hadoop-3.1.0
export HADOOP_MAPRED_HOME=/opt/server/hadoop-3.1.0
export HIVE_HOME=/opt/server/apache-hive-3.1.2-bin

3、加入mysql的jdbc驱动包

bash 复制代码 
cd /opt/server/sqoop-1.4.7.bin__hadoop-2.6.0/lib
# mysql-connector-java-5.1.38.jar

三、hadoop配置内存

修改yarn-site.xml

xml 复制代码 
<configuration>
    <!-- Site specific YARN configuration properties -->
    <property>
        <name>yarn.nodemanager.aux-services</name>
        <value>mapreduce_shuffle</value>
    </property>
    <property>
        <name>yarn.nodemanager.vmem-pmem-ratio</name>
        <value>4</value>
    </property>
</configuration>

重启

bash 复制代码 
cd /opt/server/hadoop-3.1.0/sbin
./stop-all.sh
./start-all.sh

四、导入数据到hive

1、hive创建数据库

sql 复制代码 
create database music;
use music;

2、hive创建数据表

sql 复制代码 
# -- 将数据当做一列放入表中，后续再使用sql进行分割处理
CREATE TABLE chart_content(
   content STRING
);
CREATE TABLE playlist_content (
   content STRING
);

3、hive加载csv文件进hive表

bash 复制代码 
load data local inpath '/opt/data/chart.csv' into table chart_content;
load data local inpath '/opt/data/playlist.csv' into table playlist;

4、创建表

bash 复制代码 
CREATE TABLE `chart`  (
  `Chart` string,
  `Rank` string,
  `Title` string,
  `Times` string,
  `Singer` string
);

CREATE TABLE `playlist`  (
  `PlaylistID` string,
  `Type` string,
  `Title` string,
  `PlayCount` string,
  `Contributor` string
);

CREATE TABLE playlist (
   `PlaylistID` string,
  `Type` string,
  `Title` string,
  `PlayCount` string,
  `Contributor` string
)
row format delimited
fields terminated by ',';

5、将数据插入表中去掉","

sql 复制代码 
INSERT INTO TABLE `chart`
SELECT
  split(content, ',')[0] AS `Chart`,
  split(content, ',')[1] AS `Rank`,
  split(content, ',')[2] AS `Title`,
  split(content, ',')[3] AS `Times`,
  split(content, ',')[4] AS `Singer`
FROM `chart_content`;

INSERT INTO TABLE `playlist`
SELECT
  split(content, ',')[0] AS `PlaylistID`,
  split(content, ',')[1] AS `Type`,
  split(content, ',')[2] AS `Title`,
  split(content, ',')[3] AS `PlayCount`,
  split(content, ',')[4] AS `Contributor`
FROM `playlist_content`;


bash 复制代码 
SELECT
  PlaylistID,
  Type,
  Title,
  CAST(PlayCount AS int) AS PlayCount,
  Contributor
FROM playlist;
bash 复制代码 
SELECT
    REGEXP_REPLACE(Contributor, '"', '')
FROM playlist;
