1）把apache-hive-3.1.2-bin.tar.gz上傳到linux的/opt/software目錄下

2）解壓apache-hive-3.1.2-bin.tar.gz到/opt/module/目錄下面

[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的名稱為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，新增環境變數

[atguigu@hadoop102 software]$ sudo vim /etc/profile.d/my_env.sh

新增內容

#HIVE_HOME

export HIVE_HOME=/opt/module/hive

export PATH=$PATH:$HIVE_HOME/bin

重啟Xshell對話方塊或者source一下 /etc/profile.d/my_env.sh檔案，使環境變數生效

[atguigu@hadoop102 software]$ source /etc/profile.d/my_env.sh

5）解決日誌Jar包衝突，進入

[atguigu@hadoop102 lib]$ mv log4j-slf4j-impl-2.10.0.jar log4j-slf4j-impl-2.10.0.jar.bak

3.2 Hive元資料配置到MySQL

3.2.1 拷貝驅動

將MySQL的JDBC驅動拷貝到Hive的lib目錄下

[atguigu@hadoop102 lib]$ cp /opt/software/mysql-connector-java-5.1.48.jar /opt/module/hive/lib/

3.2.2 配置Metastore到MySQL

在$HIVE_HOME/conf目錄下新建hive-site.xml檔案

[atguigu@hadoop102 conf]$ vim hive-site.xml

新增如下內容

<?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>000000</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>

3.3 啟動Hive

3.3.1 初始化元資料庫

1）登陸MySQL

[atguigu@hadoop102 conf]$ mysql -uroot -p000000

2）新建Hive元資料庫

mysql> create database metastore;

mysql> quit;

3）初始化Hive元資料庫

[atguigu@hadoop102 conf]$ schematool -initSchema -dbType mysql -verbose

3.3.2 啟動hive客戶端

1）啟動Hive客戶端

[atguigu@hadoop102 hive]$ bin/hive

2）檢視一下資料庫

hive (default)> show databases;

OK

database_name

default
