默认情况下, Hive 使用内嵌的 Derby 数据库保存元数据, 通常生产环境会使用 MySQL 来存放 Hive 元数据。

使用下面脚本一键安装MySQL 5.7 安装后会显示mysql的初始密码，是所有初始密码登陆后修改为你的需要密码

			
curl -s https://raw.githubusercontent.com/oscm/shell/master/database/mysql/5.7/mysql.server.sh | bash

2016-02-16T08:22:58.253030Z 1 [Note] A temporary password is generated for root@localhost: sd%%my.Ak7Ma
			
			

安装 MySQL JDBC 连接库。

			
curl -s https://raw.githubusercontent.com/oscm/shell/master/database/mysql/5.7/mysql-connector-java.sh | bash
			
			

创建一个 hive 数据库用来存储 Hive 元数据，且数据库访问的用户名和密码都为 hive。

			
mysql> CREATE DATABASE hive; 
Query OK, 1 row affected (0.03 sec)
			
			

创建用户hive并授权访问hive数据库

			
mysql> CREATE USER 'hive'@'localhost' IDENTIFIED BY 'hive';
Query OK, 0 rows affected (0.04 sec)

mysql> GRANT ALL ON hive.* TO 'hive'@'localhost' IDENTIFIED BY 'hive';
Query OK, 0 rows affected (0.01 sec)

mysql> GRANT ALL ON hive.* TO 'hive'@'%' IDENTIFIED BY 'hive';
Query OK, 0 rows affected (0.00 sec)

mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.00 sec)

mysql> quit;
Bye
			
			

安装 Hadoop 采用单机模式

			
curl -s https://raw.githubusercontent.com/oscm/shell/master/distributed/hadoop/hadoop-2.8.0.sh | bash
curl -s https://raw.githubusercontent.com/oscm/shell/master/distributed/hadoop/single.sh | bash
curl -s https://raw.githubusercontent.com/oscm/shell/master/distributed/hadoop/startup.sh | bash 
			
			

可以从 Apache 镜像站点中下载最新稳定版的 apache-hive-2.1.1-bin.tar.gz

			
cd /usr/local/src
wget http://mirrors.hust.edu.cn/apache/hive/stable-2/apache-hive-2.1.1-bin.tar.gz

tar zxf apache-hive-2.1.1-bin.tar.gz
mv apache-hive-2.1.1-bin /srv/apache-hive-2.1.1
ln -s /srv/apache-hive-2.1.1/ /srv/apache-hive
chown hadoop:hadoop -R /srv/apache-hive-2.1.1
			
			

			
cat > /srv/apache-hive/conf/hive-env.sh <<'EOF'
export JAVA_HOME=/srv/java
export HADOOP_HOME=/srv/apache-hadoop
export HBASE_HOME=/srv/apache-hbase
export HIVE_HOME=/srv/apache-hive
export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HIVE_HOME/bin
EOF

cat >> ~/.bash_profile <<'EOF'
export JAVA_HOME=/srv/java
export HADOOP_HOME=/srv/apache-hadoop
export HBASE_HOME=/srv/apache-hbase
export HIVE_HOME=/srv/apache-hive
export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HIVE_HOME/bin
EOF

source ~/.bash_profile
			
			

安装JDBC驱动

			
[root@localhost apache-hive]# ln -s  /usr/share/java/mysql-connector-java.jar /srv/apache-hive/lib/
[root@localhost apache-hive]# ll /srv/apache-hive/lib/mysql-connector-java.jar 
lrwxrwxrwx 1 root root 40 Jun 29 01:59 /srv/apache-hive/lib/mysql-connector-java.jar -> /usr/share/java/mysql-connector-java.jar
			
			

修改 hive-site.xml 配置文件，配置工作目录

			
<property>
    <name>system:java.io.tmpdir</name>
    <value>/tmp/hive</value>
</property>
<property>
    <name>system:user.name</name>
    <value>hadoop</value>
</property>

  <property>
    <name>hive.querylog.location</name>
    <value>/tmp/live/hadoop</value>
    <description>Location of Hive run time structured log file</description>
  </property>
  <property>
    <name>hive.exec.local.scratchdir</name>
    <value>/tmp/hive</value>
    <description>Local scratch space for Hive jobs</description>
  </property>
  <property>
    <name>hive.downloaded.resources.dir</name>
    <value>/tmp/hive/${hive.session.id}_resources</value>
    <description>Temporary local directory for added resources in the remote file system.</description>
  </property>

  <property>
    <name>hive.querylog.location</name>
    <value>/user/hive/log</value>
    <description>Location of Hive run time structured log file</description>
  </property>
			
			

把默认的 Derby 修改为 MySQL 需要在该文件中配置 MySQL 数据库连接信息。

			
<property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:derby:;databaseName=metastore_db;create=true</value>
    <description>
      JDBC connect string for a JDBC metastore.
      To use SSL to encrypt/authenticate the connection, provide database-specific SSL flag in the connection URL.
      For example, jdbc:postgresql://myhost/db?ssl=true for postgres database.
    </description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionDriverName</name>
    <value>org.apache.derby.jdbc.EmbeddedDriver</value>
    <description>Driver class name for a JDBC metastore</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionUserName</name>
    <value>APP</value>
    <description>Username to use against metastore database</description>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionPassword</name>
    <value>mine</value>
    <description>password to use against metastore database</description>
  </property>
			
			

将上面配置项 value 改为下面的配置

			
  <property>
    <name>javax.jdo.option.ConnectionURL</name>
    <value>jdbc:mysql://localhost:3306/hive?createDatabaseIfNotExist=true&amp;characterEncoding=UTF-8&amp;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>hive</value>
  </property>
  <property>
    <name>javax.jdo.option.ConnectionPassword</name>
    <value>hive</value>
  </property>
			
			

启动 Hive 前你必须做两件事，一是创建HDFS目录，二是初始化 MySQL 数据库。

为 Hive 创建 HDFS 工作目录并给它们赋相应的权限。

			
[root@localhost ~]$ su - hadoop
[hadoop@localhost ~]$ /srv/apache-hadoop/bin/hdfs dfs -mkdir -p /user/hive/warehouse
[hadoop@localhost ~]$ /srv/apache-hadoop/bin/hdfs dfs -mkdir -p /tmp/hive
[hadoop@localhost ~]$ /srv/apache-hadoop/bin/hdfs dfs -chmod g+w /user/hive/warehouse
[hadoop@localhost ~]$ /srv/apache-hadoop/bin/hdfs dfs -chmod 777 /tmp/hive
			
			

初始化 MySQL 数据库

			
[hadoop@localhost ~]$ /srv/apache-hive/bin/schematool -dbType mysql -initSchema

如果使用内嵌数据库 derby 请使用下面命令初始化

schematool -initSchema -dbType derby
			

启动 Hadoop

			
[hadoop@localhost ~]$ /srv/apache-hadoop/sbin/start-all.sh 
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [localhost]
localhost: starting namenode, logging to /srv/apache-hadoop-2.8.0/logs/hadoop-hadoop-namenode-localhost.localdomain.out

进入 Hive 然后输入 show databases; 测试安装是否正常。

			
[hadoop@localhost conf]$ /srv/apache-hive/bin/hive

hive> show databases;

至此 Apache Hive 已经安装配置完成！

尝试执行下面的SQL命令测试Hive是否正常

create database test;
use test;
create table test_table (id int,name string) row format delimited fields terminated by ',' stored as textfile
insert into test_table values (1, 'Neo');
select * from test_table;
			

hiveserver2 提供远程访问 Hive 服务，用户可以通过IP地址和端口号连接到Hive，类似mysql client

			
[hadoop@localhost ~]$ /srv/apache-hive/bin/hiveserver2

检查端口

[hadoop@localhost bin]$ ss -lnt | grep 10000
LISTEN     0      50           *:10000                    *:* 
			

测试 beeline 是否可以正常进入

			
[hadoop@localhost ~]$ /srv/apache-hive/bin/beeline -u jdbc:hive2://
