Hive安装，

Hive安装，

一、概述

• hadoop-3.1.1.tar.gz
• apache-hive-3.1.1-bin.tar.gz

二、安装

1、安装mysql，并登录mysql，并修改权限：

yum install -y mysql-server

mysql

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

flush privileges;

2、配置环境变量

vim /etc/profile

#增加HIVE环境变量内容
export HIVE_HOME=/data/local/hadoop/apache-hive-3.1.1-bin
export PATH=$PATH:$HADOOP_HOME/bin:$HIVE_HOME/bin
export CLASSPATH=$CLASSPATH:$HIVE_HOME/bin

source /etc/profile

3、创建hive-env.sh文件：

cp hive-default.xml.template hive-site.sh
vi hive-site.sh

#增加内容
export HADOOP_HOME=/usr/local/hadoop-3.1.1
export HIVE_CONF_DIR=/usr/local/apache-hive-3.1.1/conf

4、创建hive-site.sh

vi hive-site.sh

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
    # hdfs的数据存放路径
    <property>
        <name>hive.metastore.warehouse.dir</name>
        <value>/data/hive/warehouse</value>
    </property>
    # 数据库连接
    <property>
        <name>javax.jdo.option.ConnectionURL</name>
        <value>jdbc:mysql://node1:3306/hivedb?allowMultiQueries=true&amp;useSSL=false&amp;verifyServerCertificate=false</value>
    </property>
    <property>
        <name>javax.jdo.option.ConnectionDriverName</name>
        <value>com.mysql.cj.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>
    # 其它
    <property>
        <name>hive.metastore.schema.verification</name>
        <value>false</value>
    </property>
    <property>
        <name>datanucleus.readOnlyDatastore</name>
        <value>false</value>
    </property>
    <property>
        <name>datanucleus.fixedDatastore</name>
        <value>false</value>
    </property>
    <property>
        <name>datanucleus.autoCreateSchema</name>
        <value>true</value>
    </property>
    <property>
        <name>datanucleus.autoCreateTables</name>
        <value>true</value>
    </property>
    <property>
        <name>datanucleus.autoCreateColumns</name>
        <value>true</value>
    </property>
</configuration>

5、将下载好的驱动拷贝到hive的lib目录下。

cp /data/local/hadoop/mysql-connector-java-8.0.12.jar /data/local/hadoop/apache-hive-3.1.1-bin/lib

6、在 mysql 服务器中新建空数据库 hivedb，跟 hive-site.xml 中配置的数据库名称一致

7、首次启动初始化schema

./bin/schematool -dbType mysql -initSchema

8、验证

[root@node1 conf]# hive
which: no hbase in (/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/hadoop-3.1.1/sbin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/hadoop-3.1.1/sbin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/hadoop-3.1.1/sbin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/hadoop-3.1.1/sbin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/hadoop-3.1.1/sbin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/hadoop-3.1.1/sbin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/hadoop-3.1.1/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/data/local/jdk1.8.0_191/bin:/root/bin:/data/local/jdk1.8.0_191/bin:/data/local/hadoop/hive-1.1.0-cdh5.7.0/bin:/data/local/jdk1.8.0_191/bin:/data/local/jdk1.8.0_191/bin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/hadoop-3.1.1/sbin:/data/local/hadoop/hive-1.1.0-cdh5.7.0/bin:/data/local/jdk1.8.0_191/bin:/data/local/hadoop/hive-1.1.0-cdh5.7.0/bin:/data/local/jdk1.8.0_191/bin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/hive-1.1.0-cdh5.7.0/bin:/data/local/jdk1.8.0_191/bin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/apache-hive-3.1.1-bin/bin:/data/local/jdk1.8.0_191/bin:/data/local/hadoop/hadoop-3.1.1/bin:/data/local/hadoop/apache-hive-3.1.1-bin/bin)
