[大数据]hive安装配置

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

[root@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

[root@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

[root@hadoop102 software]$ sudo vim /etc/profile

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

[root@hadoop102 software]$ source /etc/profile

5）解决日志Jar包冲突，进入/opt/module/hive/lib目录

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

6)将MySQL的JDBC驱动拷贝到Hive的lib目录下

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

7)在hive/conf下创建文件夹hive-site.xml

[root@Hadoop171 conf]# touch hive-site.xml

8)在hive-site.xml中写入以下内容

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    <property>
      <name>javax.jdo.option.ConnectionURL</name><!--mysql地址-->
      <value>jdbc:mysql://192.168.200.171:3306/metastore?createDatabaseIfNotExist=true</value>
      <description>JDBC connect string for a JDBC metastore</description>
    </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><!--mysql用户名-->
    </property>

    <property>
        <name>javax.jdo.option.ConnectionPassword</name>
        <value>1234</value><!--mysql的密码-->
    </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>192.168.200.171</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>

9）初始化元数据库

[root@Hadoop102 hive]# schematool -initSchema -dbType mysql

10）启动hive

[root@hadoop102 hive]$ bin/hive

11）查看数据库

hive (default)> show databases;

OK

database_name

default
